tcl 55us5800 lcd panel quotation

Then again, if you want a 65-inch Roku TV, your only option is to go 4K, and the 65-inch TCL 65US5800 is a great value. But for smaller sizes, the standard 1080p Roku TVs are better deals.

These sets" main competition, aside from other Roku TVs, comes from the 4K sizes in Vizio"s D and E series. The pricing is comparable, but from what I"ve seen the Vizios deliver better picture quality largely thanks to their local dimming backlights. Of course the main reason to get a Roku TV is for its superior streaming and app experience, and if that"s your aim, and you want 4K, these TCLs are just the ticket.

Series information: I performed a hands-on evaluation of the 50-inch 50UP130, but most of the observations I mad there apply to the two sizes in the US5800 series as well. All sizes in both the UP130 and US5800 series have identical specs and according to the manufacturer should provide very similar picture quality. The only differences between the two series are the remote and styling; see below for details.TCL US5800 and UP130 series 4K Roku TVs

The menus and apps loaded quickly on the TCL TV, which behaved every bit as speedily as the Roku Streaming Stick. For more on Roku in general, check out that review.

I reviewed the TCL 50UP130 (which Roku says has the same image quality as the US5800) and the Insignia NS-­50DR710NA17, two 50-inch 4K Roku TVs, together as part of the same comparison lineup. Image quality, as I saw with last year"s non-4K Roku TVs, was good but not great, and as I"ve seen with so many reviews in the past, there"s no real benefit to having 4K resolution, whether via streaming or Blu-ray. Unless you plan to use these TVs as large computer monitors, you won"t see much, if any benefit compared to 1080p models, even on the larger screen sizes.

Dim lighting:Compared against the Vizios, the TCL and Insignia had a difficult time reproducing the same convincing depth of black. In Samsara, for example, the screen behind the titles, the shadows around the erupting volcano and the recesses of the carvings all appeared relatively light. Compared against the Samsung and LG in this test, however, the Rokus weren"t significantly worse, the the Roku"s detail in shadows was fine.

Video processing:As I expected from 60Hz TVs the Roku sets delivered minimal motion resolution, so sensitive viewers might notice a bit more blurring than on other TVs, but I found it difficult to see any loss of detail with normal program material. They delivered 1080p/24 cadence well, and both were solid combatants of input lag (see the Geek Box below for more)--although the Insignia was slightly better at 28ms, compared to 45ms for the TCL.

Uniformity: Both Roku TVs were a bit worse than the others in this category, with more brightness variations visible across the screen in test patterns. With most content the variations weren"t visible, however, and when I watched a bit of hockey--with fast camera movement and a mostly-white screen that can expose such variations--the Roku sets didn"t look any worse than the others. They also lacked any of the egregious bright spots and "flashlights" that can plague other LCDs.

First a note about TCL, a manufacturer that few are familiar with in North America. This is a huge company with a $4B panel manufacturing facility in China. They also have a research facility in Silicon Valley and claim to be the third largest manufacturer of TVs in the world.

I can’t honestly say that the picture quality on the 4K UHD version of the TCL Roku TV looks appreciably better than the 1080p version. With good 1080p and 4K sources there is a bit more clarity and cleaner images edges. Picture quality including blacks, contrast, and color is not the standout feature of these TCLs. Black levels suffer turning more bluish black at times. From side angles contrast and color saturation degrade worse than the average LED backlit LCD TV, but less than expected. This begins at around 15 degrees off-center. Motion blur is rarely visible, though judder (side to side jerky motion especially present when a camera pans slowly) is present due to the fact that there is no refresh rate smoothing features present in the TV. Even though TCL states that the TV is 120Hz, it"s actually a 60Hz native panel. Another exception to the specifications is that this is not the full array direct lit backlighting you should compare with top quality and brands. In this case, full array direct lit LED to LCD is just an economical way to produce the TV much like some of the very small inexpensive 32” models we"ve seen from other manufactures. This is evinced by screen uniformity that is weak both on black and solid medium grays. This means that you may see some clouding along the edges or corners when displaying a black or very dark screen. From our experience with LCD TVs, it may become more pronounced over time. With a gray or medium color screen you may see some darker shadows in various areas of the screen. When viewing our stock Fifth Element BluRay we noted some inaccuracy in colors with a red push causing flesh tones to look flushed. Greens are also difficult for the TV to produce accurately. On the positive side, I was impressed with the brightness produced.

All of that said, the picture is just a hair better than acceptably decent is the best way I can put it. It"s certainly not bad and a bit better than we expected. You aren"t spending a lot to get a superior panel or color performance on this TV. That"s not its strong suit. For the price, the picture is actually very good.

The TCL Roku Remote is really a Roku manufactured remote. Roku is good at operation, and I like the speed with which the small simple remote controls everything. The audio/volume buttons are located on the right side of the remote. It"s easy to accidentally press the mute button. The picture and other menu settings are accessed from the asterisk wheel button. Conveniently, there are buttons for Netflix, Amazon instant, Mgo, and rdio on the remote face. There are free Apps for iOS and Android smart phones that even contain a voice controlled search. I did not try the voice search nor the smart phone App. But just know that it"s an option. I like the simple Roku remote.

Simplicity and savings are the hallmarks of the TCL Roku TV 55US5800 4K Ultra HD TV. The 55-inch set has Roku TV"s expertly designed smart-TV interface, with thousands of online channels, and is available for $500. It"s not quite our top value pick, but the TCL"s features and price should make it an instant favorite among bargain hunters.

The TCL Roku TV has two splayed feet on each side to support it on a table top; it"s a design similar to that of Vizio and other popular models. For connecting the TV to other components, the TCL includes four HDMI ports (all supporting 4K copy protection) and built-in Wi-Fi for making that all-important internet connection to support Roku"s channels.

The TCL LCD set uses LED full-array backlighting but not local dimming. Consequently, it can"t independently adjust the brightness of different parts of the screen as adroitly as other sets. Furthermore, the TCL Roku TV does not support the latest high-dynamic range (HDR) or Dolby Vision picture formats. So it lacks the ability to display subtle contrasts, and the set"s skewed color balance can make the picture look cooler and lacking in warmer deep red tones.

In our tests, the TCL Roku TV revealed some weaknesses, particularly in color accuracy. In our charts, it was very skewed toward the cooler blue end of the spectrum, making for less than accurate color reproduction.

The 55-inch TCL Roku TV delivered over 98 percent of the standard (rec. 709) color space, but its color accuracy waned with a Delta E score of 10.49 (numbers closer to 0 are better). By comparison, a 50-inch Insignia Roku TV had a much better Delta E score of 1.12. Extended viewing confirmed our results.

In The Martian, the TCL Roku TV"s picture could make faces look plastic and artificial. (A complaint I also had with Vizio"s much more expensive P-Series set.) The Red Planet also tended to look more gray, compared with the orange hues of the dust clouds emphasized by top-notch sets such as LG"s OLED TVs. Even a white turtleneck looked more blue on the TCL TV.

A 4K music video of an Emi Meyer performance showed that the TCL picture loses out in rendering deep reds, such as those in her dress, which lacked saturation and depth. Viewing The Amazing Spider-Man 2, however, didn"t elicit any obvious flaws.

Similarly, the TCL Roku TV did a good job upscaling HD content to 4K. While the TV is rated as a 120 Hz set in some literature, it"s a 60 Hz display, which means that some fast motion can look a little blurred. However, I didn"t find any such shortcomings distracting. In fact, while there"s some softness to the picture, eliminating some details such as the distant stars in the movie Gravity, there aren"t any excessive artifacts (usually associated with excessive video processing) in chase scenes like those in Skyfall.

TCL"s 55-inch Roku TV has several preset audio settings, including Normal, Speech, Theater and Big Bass. The Theater option delivers the most expansive, open sound, but the audio is still very compressed and focused toward the center of the image.

The speech mode is moderately effective at emphasizing dialogue but could be better (especially for late-night viewing when you"re trying to keep the volume down but still want to follow the plot). Switching to big bass doesn"t so much boost the lower notes as it does suppress the higher ones, giving you the false impression you"re getting more from the low end. While serviceable, the built-in sound system of the TCL Roku TV is generally tinny and scratchy compared with a good $200 sound bar.

For example, I was able to download and install a new YouTube app faster than I could perform a similar update on LG"s webOS system. Additional benefits include a 4K Roku channel that makes it easier to find high-resolution content, and the My Movie Watchlist, where you can add movies you"d like to see and have it automatically notify you when the programs become available.The best feature of the TCL TV is its Roku interface.

Making fine-grained picture adjustments to the TCL set isn"t something most owners are likely to do, but TCL now allows you do so, albeit via a free smartphone app. You can tweak color gamma presets, noise reduction and white balance.

While it is far from the best 4K ultra-HD display we"ve tested, the 55-inch TCL Roku TV gets a positive rating thanks to its Roku smart-TV interface and exceptionally low price. Shoppers should note, however, that the Insignia Roku TV we"ve tested offers a better, albeit smaller, 50-inch picture — as well as the same excellent Roku interface — for the same price.Today"s best TCL Roku TV 55US5800 4K deals
