logitech keyboard with lcd screen manufacturer

Setting aside the screen for a moment, the G19 keyboard itself is only slightly more impressive than the most recent version of the G15. The core key design provides the same crisp keystrokes, with the same 12 "G" keys on the left edge. As with the G15, the G19 gives you three different switchable modes, so you end up with 36 effective customizable keys, along with on-the-fly macro recording. Logitech also includes another hallmark of its G-series keyboards, a switch that lets you disable the dedicated "Windows" key, so you don"t accidentally switch to your desktop screen during gameplay with an errant key press.

New to this model (aside from the color LCD) is its capability to recognize five simultaneous key presses. Macro-happy gamers and digital artists, in particular, should appreciate that feature, which opens up a greater level of mastery to run repetitive commands. We"re also glad to see that the G19 now has two powered USB 2.0 jacks. The G15 is stuck with USB 1.1, which is not as fast. Anyone who regularly transfers large amounts of data between a PC and a portable storage device or media player will benefit from that added bandwidth.

Other features include a smart drum-style volume control above the G19"s number pad, on top of which you"ll also find a set of easily accessible media play controls. As before, the G19 ties into iTunes, Windows Media Center, and other media software apps. Last but not least among the new, non-LCD-related highlights is the option to select from 16 million different colors for the backlit keys. You customize the colors through the only-somewhat-intuitive Logitech Profile software, which lets you tie three different colors to the three mode buttons for the programmable "G" keys. We wish it had a dedicated button to scroll through at least a few preset colors, though. We also wish Logitech would consolidate its configuration software into one application. Instead you have to bounce around between the G-series Key Profiler for setting up the G keys, and a separate LCD Manager app for the built-in screen. Which brings us, finally, to the color LCD.

As with the G15, the G19 provides you with a secondary display, ostensibly to minimize the number of times you switch out of a game to the Windows desktop to check the time, your in-box, or get other information. Unlike the G15"s two-tone model, the G19 gets full color output and a larger 320x240 screen size. Logitech includes 11 different applications you can use on the screen of the G19, among them a clock, a system performance monitor, an RSS reader, photo and video players, and an app that lets you play YouTube videos. All of those programs have option screens--accessible through both the LCD Manager software and through a set of screen menu controls on the keyboard itself--that let you change content source folders and make other adjustments.

The G19 also comes with built-in support for 46 PC games, and four different applications, including Ventrilo, the popular third-party voice chat software favored by many PC gamers. "Support" for those various titles means essentially that the screen will display different information, such as character stats and ammunition counts. We haven"t tried every game on the list, many of which are outdated, but we never found the game-specific information that handy during gameplay. We can see a few possibilities that would make the LCD screen more useful, such as giving you an extra inventory screen or showing an in-game map, but we haven"t seen those kinds of features implemented in the handful of titles we"ve tried. We do, however, like the Ventrilo plug-in that lets you know who"s talking, which can be useful if you don"t know everyone in your World of Warcraft guild by voice.

Potentially more exciting is that, as with the G15, Logitech also includes a software development kit for the G19"s LCD. It took a while for the enthusiast community to embrace the G15"s kit, but once it did, all kinds of mini apps became available for public download. We don"t expect the G19"s software library to have blossomed in the three months since the keyboard"s release, but without a critical mass of homemade applications, it"s hard for us to say what kinds of programs might come from the community. You can use some of the homebrewed G15 apps on the G19, but not all of them work on the new color screen. We also can"t help but wonder what effect the G19"s high price will have on the adoption rate among the enthusiast community. If fewer people buy the G19, that will surely affect the amount of collective effort behind any software development.

The keyboard everyone in the world drooled over for months and months is out there on the market. It’s got its own LCD screen, it looks slick as hell, and it costs a mint. You know you wantit, but should you really buy it?

The G19 is probably the second most anticipated keyboard of all time, after the infamous Optimus Maximus. The inclusion of a separate full-color LCD screen (an update to its predecessor, the G15) was like geek candy, but the question secretly on everybody’s mind was “is it actually going to be useful?” And as it turns out… not really. Let’s explore that right off the bat so you don’t have to read the rest of this review.

The screen itself is good. It’s 320×240, nice and sharp, and color is vibrant. It’s basically like your average mid-range cell phone screen. Viewing angle is pretty dismal, but you’re usually right in front of it and it swivels vertically anyway. So what’s on it?

Well, the screen has a few basic “channels.” YouTube, RSS Feed, song display, “my videos,” a clock, a performance monitor, a picture viewer, and a timer. Of these, the performance monitor is really the only useful one, because I can’t think of a reason you’d want or need to navigate YouTube or your pictures and videos via this tiny screen. The onlysituation I can think you’d do it is while in a full-screen app or game that doesn’t minimize or alt-tab well. The RSS reader is adequate, but only displays one story at a time. You’d really have to try hard to make use of this thing.

Where’s my bandwidth monitor for uTorrent? Where’s my ammo readout in Counter-Strike or my mini-map in Assassin’s Creed? Of course, it’s on the game and app developers to make that happen, but it’s on Logitech to press them on it. If Logitech is going to roll something like this out, they needed to roll out big or customers are going to see that they’re paying for a fantasy device.

Lastly, the LCD screen is not some self-contained little thing. It runs a bunch of processes in the background all the time, and on XP at least also had an item (or two) in the taskbar all the damn time. Come on, that’s unforgivable.

So unfortunately, that’s the G19’s primary selling point, and it’s not very convincing. Maybe in a year there will be more support for it, or a touchscreen, or what have you, but at the moment it’s just not worth it. But what about the rest of the keyboard?

The G19 is, aside from the screen, a very competent keyboard. The keys are big, well-spaced, and have a pleasant resistance to them. They seem to project further from the base than other keyboards, but I have been using the very flat Lycosa for months, so that could just be a bad comparator. The backlighting is the best I’ve seen, and covers the entire rainbow; you can set colors to profiles so you know which you’re in. All illumination turns off with the touch of a button so you don’t have to fiddle with anything if you want a blackout while you watch a movie.

Like the G19’s predecessor, the G15, you’ve got macro keys on the left side and a hard profile switcher — work, play, movie editing, or what have you. Plus, like most gaming keyboards, it detects games you start and will automatically launch a macro/key profile. The macro editor worked well and I use it for blogging shortcuts (inserting image code, signatures, etc) and that sort of thing. I’m not a big macro user but if you are I think you’d enjoy this. The macro keys themselves (G1-G12) are easily available and organized into little blocks of four, excellent for finding without looking (the F-keys are also blocked, thank god).

The other features on the keyboard include a (thank you Jesus) Windows key disabler and the usual media controls. The media buttons worked perfectly for me, although it would have been nice to have them be able to launch the player instead of just control it. The big mute button and volume wheel are responsive and feel good.

So what we’ve got here is a failure to launch. The LCD screen has a lot of potential but is only used for mundane tasks which have no real reason to be on there, or at least don’t justify the cost. Other than that, it’s a great keyboard. I enjoy typing on it, the macros are handy and responsive, and everything works perfectly well. It’s just not worth dropping $200 on because it has a screen. Logitech makes great keyboards, and you’d be better off going with another one, at least until this one has adequate support from the community and industry.

In software, it"s said that everything grows until it can read mail. In hardware, the corresponding dictum is that everything grows until it has an LED screen. Accordingly, Logitech has taken its high-end G15 gaming keyboard and added an attractive, if superfluous, display."The Logitech G15 keyboard offers an integrated LCD screen which can be customized to view vital in-game information, system status, CPU memory available or data from other applications without interrupting game play. The G15 keyboard offers PC gamers a tactical advantage with six programmable G-keys - and three mode keys - to create useful macros on the fly that play-back with a single key press."

The keyboard is $100 and available immediately. Availability of in-game support, however, is a bit cloudy. But really, it"s the glowing red, KITT-like awesomeness on sale, not actual utility.

Last month, Logitech sent over a brand new, fairly expensive mouse and keyboard combination that the company is marketing to gamers. If purchased together, at full MSRP, the G19s and G602 (review here) would cost the average consumer a whopping $280. And that"s before tax and/or shipping. But is the recently-refreshed combination really worth all that cash?

The Logitech G19s is easily the most feature-packed keyboard that"s ever entered my home, thanks to its built-in LCD screen and programmable macro buttons; however, the average customer isn’t likely to find a convincing reason to spend $200 for Logitech"s latest refresh of the G19s gaming keyboard.

That’s not to say that the device isn’t equipped with its fair share of bells and whistles but, while the G19s certainly isn’t running low on style or panache, it feels like Logitech skipped out on pretty much every major feature I’d expect to see in a keyboard with such a steep price.

Where are the mechanical switches? Why would I want powered-USB ports, as opposed to a wireless device, when the G19s doesn’t even include the headphone jack needed to plug in a headset? And why does the keyboard rely on an application that slows down my CPU boot and shutdown times?

Enough with the rhetorical questions, though. Let’s dig into the Logitech G19s bit-by-bit and see what consumers should expect from a brand new unit, what we liked about the company’s latest gaming keyboard and the various reasons why we still aren’t quite sold on the Logitech G19s.

Just as you might expect, the Logitech G19s has all the usual buttons you"d expect to find on a QWERTY, Windows-ready keyboard. The device also includes the usual suite of media keys, plus a rolling input for volume control , along with a handful of buttons mean to select/toggle various features and functions of the Logitech G19s.

Each input on the keyboard is coated in a UV-protective coating, to keep the keys from fading after a few weeks/months of heavy usage, and the folks at Logitech thoughtfully decided to make both the arrow and WASD keys a lighter shade of gray. It may not seem like much but, between those and the LCD backlighting behind every key, you shouldn"t ever really have an issue getting your hands lined up properly on the G19s.

The Logitech G19s also features a full-color LCD panel built directly into the device, which can be used to display everything from game stats to the headlines from your favorite RSS feeds. It can even play your favorite YouTube videos, provided they aren’t locked to the browser; however, the frame rate does take a pretty significant dive.

Less exciting features include a pair of powered USB ports can be found on the upper-edge of the keyboard and molding on the bottom of the G19s that is intended to help you manage the wires from your headphones and/or mouse. Assuming you haven"t spent close to a $100 on the G602 wireless gaming mouse that Logitech is hoping consumers will pair with the G19s and/or several hundred dollars on one of the many wireless gaming headsets currently available to PC gamers.

While I’ll always have a soft spot in my heart for the distinctive clicking sound produced by many of the world’s top mechanical keyboards, I’ll admit to being pleasantly surprised by just how little noise the G19s has created since showing up at my apartment last month. Not pleased enough to overlook the lack of mechanical switches under the keys, but we"ll dive into that later.

The keyboard’s UV coated keys may take a bit more force to register an input but they also feel like they’ll continue to hold up under the hours and hours of daily usage that they’ve seen in the last few weeks. The backlit keys also make it easy to see what I’m doing, regardless of the current light level in my home office.

As someone with some relatively sizable hands, and a tendency to get a bit clumsy when playing late-night Dota matches, I appreciated having a hardwired switch that enables/disables the Windows key on the G19s. Accidental minimizations aren’t necessarily an everyday issue for me but they’re just frequent enough for the switch to be one of my favorite features.

The programmable keys that line the left side of the keyboard are also handy for certain games and other tasks; especially if you’re playing an MMO or other game where macro inputs are both more efficient and (sometimes) the difference between life and death/rage quits. I also find them surprisingly useful in my day-to-day life, though I suppose not everyone is slapping the same footer paragraph onto a handful of new articles each business day.

Best of all, each of the twelve keys can be programmed three times, toggled via a set of keys in the upper-left corner of the device, and the ability to alter the backlight behind your keys makes it easy to remember which macro configuration is currently enabled. Advanced coders will also be happy to know an emulator for the Logitech G19s" built-in LCD screen comes bundled with the software, making it a bit easier to program and test your own applets for the device.

That’s how much Logitech wants customers to pay for the Logitech G19s. Two hundred dollars for a new keyboard that, while certainly pleasing to the eye, seems to value outward appearance more than usefulness or general functionality. I mean, it doesn’t even include mechanical inputs.

There are at least two different Das keyboards for significantly less, and I bet the Control and Alt buttons on those don"t start to wear out after just one month"s worth of usage. I wish I could say the same for the Logitech G19s.

I think it’s also worth pointing out that just about everything that currently sets the G19s apart from other keyboards are features that require you to take your eyes off your monitor. I don’t know about you guys, but taking my eyes off my screen is the last thing I want to do in the middle of a game; much less reflex-focused games like Call of Duty, Dota 2 or League of Legends.

While the keyboard’s YouTube applet quickly became a personal favorite – if only because it gave me a chance to say, “Hey, look what this thing can do…” whenever friends come over – there’s no discernible way to alter the button combination that queues the videos. It’s an all-or-nothing setting that either plays any/every YouTube URL that hits your clipboard, or the keyboard ignores any/all attempts to push video to the G19s’ 2-inch screen.

The Logitech G19s is great but, at the end of the day, I just cannot envision spending two hundred dollars on it. Then again, I don’t play games for a living – well, at least not competitively --so it’s always possible that I just don’t understand why a particular feature of the G19s makes the device worth its current price. I’ll also admit to being a bit of a penny-pincher when building/outfitting my computers.

Watching Curren$y videos on the keyboard’s diminutive LCD screen is entertaining once or twice, but not something I’d ever do outside of the rare occasions when I can show the feature to a friend that’s yet to see the new toy on my desk. The same can be said for just about every other applet currently available for the G19s.

I mean, nobody really needs anything more than the $10-$20 keyboard/mouse combo that used to come standard with any new computer, but the whole idea is that it’s fun to pack a few extra features into an otherwise boring device that many of us use on a daily basis.

So, from that perspective, the G19s succeeds in just about every way you could hope for. It’s flashy, packed with over-the-top functionality and just enough practical application for a certain crowd to justify the purchase. But the lack of mechanical switches is just too big an oversight for me to ignore, and I suspect I’m not alone.

DISCLAIMER: As mentioned at the top of this post, the Logitech G19s review you just read is based on time spent with a keyboard provided to me (free-of-charge) by a representative of the popular peripheral manufacturer; however, Logitech did not retain any say in the contents of this review.

Have you had a chance to spend any time with the latest iteration of the Logitech G19s? Disagree with our analysis of the popular peripheral manufacturer’s latest premium gaming keyboard? Think you’ve discovered something (like a new applet) that would change our mind about the Logitech G19s?

I"m considering the possibility of my friend (although he"s being kind of a d♥♥♥ lately & hard to get a hold of) modding the screen from my G19s (the one that is wearing out & I"m attempting to replace) into an external USB case so that the screen can still be used, if not the keyboard itself; the only reason I even considered this was because he"s been known to put backlit, high-definition screens into old handheld game systems, so he"s pretty smart when it comes to this, but it might require leaving the entire board for the keyboard in one piece (if anything, I suppose I could keep the old keyboard connected to the computer for the screen only & use another keyboard that isn"t having the sticking problems)... Of course I still have to use old software/drivers regardless, seeing as Logitech still can"t seem to fix the issue... And just FYI, the G19 also has the capability to play videos (even online videos & live streams) & picture shows on it, however I"ve never used it for that purpose (it was always used for informational purposes in my case). There were a number of functions that were also available, however I didn"t particularly want those running while running games or streams of those games, using more processing power/bandwidth than is necessary.

Of the nearly 200 we"ve tested, the Keychron Q6 is by far the best keyboard. While we recommend the full-size Q6 here, the Q-series consists of a range of keyboard sizes, from the typing and programming-friendly Keychron Q2 to the tiny Keychron Q4 or even the TenKeyLess Keychron Q3. Regardless of what size you get, each Q-series keyboard offers an unparalleled out-of-the-box typing experience and an incredibly durable build quality.

The frame of this keyboard is solid aluminum, so we don"t recommend tossing this into your backpack and bringing it on the go unless you"re adding weight for a workout. Within this aluminum frame, the PCB sits slightly suspended in gaskets. This gasket-mounted style adds a bit of bounce when you type and reduces the overall impact of bottoming out the keys. It also gives room for two layers of sound-dampening foam around the switches to reduce the ping and rattle of your keys while you type.

Each keyboard comes with an included toolkit consisting of a hex key, a screwdriver, a switch puller, and a keycap puller, all specifically to deconstruct your keyboard. While this might seem counterintuitive, it means you have infinite possibilities to tweak and adjust the keyboard to be completely yours. Plus, you can easily repair the keyboard, improving its overall longevity. The software allows for a similar range of customization, meaning that you can create and play around with the hardware, software, and firmware to have a completely personalized board. Of course, you don"t have to alter the board in any way, especially since the stock components are all very high-quality, so just leaving the board as-is feels and sounds excellent.

The Logitech G15 keyboard is squarely aimed at gamers, but everyday users will like some of the design touches that have been incorporated. The soft blue backlighting and integrated flip-up LCD screen are features we wonder how we lived without, and the layout shows obvious signs of responding to customer feedback. The gaming macro keys round out this all-around king of keyboards. While the key pressing was slightly soft for our tastes, regular typing tasks were not a problem

There has been a recent barrage of keyboards and mice from all the major players. Most of these new input devices are geared toward gamers and media center users. The choices run the gamut:  From wireless to ergonomic, from Bluetooth enabled to pointer integrated Frankenstein-like keyboards. Logitech leads the pack, having introduced more new input devices in the past few months than in the previous three years combined. One that will no doubt catch everyone’s attention is the gamer-geared G15 keyboard. The glowing behemoth of a device is a force to be reckoned with. While it is not wireless, nor does it sport the remarkably useless keyboard mounted scroll wheel, it does contain the first multi-line programmable LCD screen. Intrigued? We were.

Out of the box, you get the keyboard, removable wrist rest, install CD and quick start guide. The G15 is wider than most keyboards in order to accommodate a number of programmable buttons along the left side. The top edge sports what look like handles, though why these are necessary is a mystery. Close to the center of the top edge are two USB ports, along with grooves in the bottom surface for running wires. The housing is a metallic light blue, which matches the backlight well. All tolled, the G15 looks mammoth on a desk, but elegantly technical, and not awkward.

Even though the keyboard is large, there is little wasted space. The G15 oozes with functionality and features. Most notable is the large, blue backlit LCD screen at the top. The LCD can be flipped down, again for a more professional look, or opened to expose the screen and media keys below. The LCD can be programmed to display different information by game developers, such as ammo, chat, etc. The default use while navigating through Windows is to cycle between displaying one screen with the date, time and an analog clock, and a display of CPU and memory usage. We didn’t realize how useful this was until we had a chance to experience it. As of the time of publication, there is a small community of G15 fanatics that is still in its infancy and assembled around G15forums.com. There is a program called LCDHype that can be used to create scripts for added LCD screen functionality. How truly useful the LCD will be is yet to be determined, but the prospects are great.

The second major feature of the G15, and the reason it is gi-normous, is the large set of programmable macro keys along the left side. Three sets of six macro keys adorn the side, along with three mode keys. The mode keys switch the set of 18 macro keys to a different set of macros, effectively making the keyboard capable of supporting 54 macros. Is this overkill? Not really. As any gamer knows, in any one game you can have different modes of play or different characters. Having the ability to switch between sets of macros is almost essential. In addition, the software supports profiles, which means that the macros are entirely game dependant. Open up World of Warcraft, and the LCD proudly displays, “World of Warcraft profile activated.” We found with City of Heroes, we had to switch back to Windows and then to the game for the profile to be correctly loaded (most likely due to the game having a separate loader, which dupes the software). Macros can be recorded using the software application or in-game with the macro record button.

The media keys are your usual, standard keys seen on many keyboards now:  Play, pause, stop, forward, and back. The center wheel spins to adjust volume. The media keys are relatively old hat for Logitech now, and support for media players is widespread. As an added bonus, the LCD will display track information for most players.

One of the stranger features of the G15 is the gaming mode switch. Such a broadly named feature should have wide-ranging effects, optimizing the keyboard performance to standards never before seen in gaming peripherals, right? This one just turns off the Windows key. We were slightly underwhelmed, even though it is a useful feature. The mute button is placed outside of the media space, where it can be accessed when the LCD is closed.

One thing Logitech has improved over the past few years is the quality of their software. That is apparent with the great configuration utility included. We found it to be very stable, and experienced no stability problems or unusual behavior. The included application allows the user to set up macros and adjust a few simple settings such as the time between LCD screen displays. The software ships with several profiles for popular games, which most gamers will probably discard for their own custom settings. The macro functionality adds a layer of productivity to the G15 as well. You could add a profile for any program, essentially making every program instantly scriptable.

On the tactile side, the G15 is a solid keyboard for everyday use, but does feel slightly “mushy.” There’s no satisfying click of the keys, but the spring back and elevation are comfortable. The wrist rest is more show than functionality, having no padding and being relatively flimsy. Some gaming keyboards sacrifice aesthetics for ergonomics, adding oddly shaped gaming pieces to the keyboard. The G15 is more of a keyboard for the avid gamer that doesn’t want to explain their input device to a casual onlooker.

The Logitech G15 is simply the keyboard to beat. The aesthetics, functionality, and uniqueness make the competition look like a child’s toy. While the full functionality of the G15 LCD has yet to be realized, even the simple programs are useful, and Logitech deserves kudos for the fact that it’s there at all. The macro keys are simple to program and arranged in a manner that makes them useful for everyday applications, and even more so for gamers. Simply put, the G15 draws a lot of attention, and it deserves it.

They say that only bad workmen blame their tools, but that’s a sentiment that doesn’t really carry over to the world of PC gaming where having the right peripherals can make all the difference. Not in the “if you own this keyboard you can be a pro gamer” kind of way perhaps, but definitely in the “this keyboard is comfortable and easier to use” way. If you’ve got a keyboard that you’re at ease with then it stands to reason that you can play better with it.

With that in mind, fans of Logitech’s older G-series keyboards such as the G15 and G11 will be pleased to know that the general feel and ergonomics of the newest G-series keyboard is essentially unchanged. The G19 differs from older models in a number of ways, but the sturdy keys and QWERTY spacings haven"t changed at all, so anyone upgrading from a G15 to the G19 won’t have to adjust in any way.

Well, that’s true for the standard alphanumeric keys anyway. The extra keys – the G-keys, the media controls, the volume controls and so on – have all been quite heavily altered from previous designs, so there might still be a small learning curve for upgraders. Still, in terms of comfort and design the G19 is a joy to use, with each key having a good amount of resistance and feedback when you hit them – ker-thunk!

Interestingly, not all of the extra functions have been expanded for the G19 as you might expect though. While the new LCD screen certainly has been improved (and we’ll get to that in a minute), some features have been trimmed down. There used to be 18 programmable G-keys for you to assign macros, shortcuts and commands to on the G15 and G11 models, but now there are only 12.

What used to be three columns of buttons organised into three blocks is now only two columns and, while that’s not going to be a problem to the everyday user or FPS gamer, hardcore MMORPG players may find something to complain about here. To regular MMOers macros are a great way to save time and effort when grinding, so scaling down the number that you can set up on a keyboard may be reason enough to stay with an older keyboard.

Thankfully though, the G19 still retains the profile function of the older G-series keyboards and you can cycle between different macro settings using the three M1, M2 and M3 buttons at the top – so 12 G-keys really equates to 36 G-keys. That’s without even considering the fact that you can set up different profiles for different games too and the G19 can still detect when you launch a specific game and will enable the profile for you automatically.

The question is whether or not there is anything in particular worth boasting about here? Game-detection and automatically loading game profiles is all well and good, but the earlier and significantly cheaper G-series keyboards could do that all too. In fact, close inspection reveals that the G19 actually uses the same software as the G15 – so, there really is nothing new in terms of how customisable the keyboard is. Same profile system, same drivers, but less keys.

The media keys have changed a bit at least, with the buttons now being a lot smaller, but chunkier than those on the G15 which sat flush with the board shell. The controls have been relocated too, shifted over above the numpad instead of beneath the LCD – probably because the LCD has changed drastically too.

The volume control in particular is worth pointing out as it’s now a fancy, small scroll wheel. While it looks very swish with its rubberised grip and all, we actually weren’t big fans of it when we had to put it to use. Not only did it wobble noticeable in the body of the keyboard, but we found it also a little insensitive, with multiple spins needed to really alter the volume.
