elecrow hdmi tft lcd display monitor 7 inch 1024x600 free sample
7inch HDMI LCD(C) supports various systems like Raspberry Pi, Banana Pi, Banana Pro, and BB Black to provide Lubuntu, Raspbian, and Angstrom images with a high resolution of 1024×600 and a Capacitive Touch Screen. Besides, it upgrades to an IPS screen with a larger visible angle and more clear display effect. Broadly you can apply it to raspberry pi, HDMI display screen, and other mini PC or even computer displays. If you gonna use it on raspberry pi zero and BB Black, you need to buy HDMI connect wire for the use and for raspberry pi zero you also need to buy A USB type A micro cable. Matched with raspberry pi, it supports raspbian, ubuntu to do single touch without touch, and while as A PC display, it supports Windows 10 / 8.1 / 8 / 7 to do the five-point touch without drive. For the Windows 10/8.1/8 OS, the touch screen supports multi-touch up to 10 points. For some Windows 7 OS, the touch screen supports single touch only. When working with Raspberry Pi, you should set the resolution of the LCD by yourself, or else the LCD screen will not work. When working with Beagle bone, this LCD module is used for display only so you can program the latest Angstrom image file to the board directly without any change. The BeagleBone will read the display parameters of the 7-inch HDMI displayer and set the resolution to 800*480 automatically.
This RC070C is the latest 7 inch portable HDMI monitor with high resolution. The resolution of the 7inch LCD display is 1024*600. This 7 inch monitor comes with a 2.0MP front camera that allows taking photos or video chat. It’s compatible with the latest Raspberry Pi 3B+/4B, BB Black, Banana Pi, and other mainstream mini PC. It is wonderful that it can be used as a Raspberry Pi display that supports capacitive touch control. It also can be used as a general-purpose-use HDMI monitor, for example: connect with a computer HDMI as the sub-display (the resolution of the output has to be able to adjust to 1024x600). Additionally, it works as a PC monitor and supports the win7, win8, and win10 systems.
I had to first edit the config.txt on my desktop computer to force the HDMI output and get a picture on that screen. Just uncomment hdmi_force_hotplug=1.
On raspberry pi, you will need to modify the /boot/config.txt file to make the screen work at a proper resolution. On Raspbian the default resolution will be 1280*720 and the letters look too small.
This will make the screen work at 1024x576 instead of the claimed 1024x600, but the problem with the 1024x600 is that it is not an standard resolution and that is why they ask you to delete "dtoverlay = vc4-fkms-V3D", but that dosen"t work on every OS
and connect the other end of the USB cable to the USB port of the LCD; then supply power to Raspberry Pi; after that if the display and touch both are OK,
Rotating the screen to the proper orientation proved challenging. The config.txt rotate commands don’t work with the raspberry pi4. I couldn’t get the xorg configuration to rotate the display. When I added kernel commandline parameters to rotate the display, that worked for the initial verbose boot screen… but once KlipperScreen loaded, it was the wrong orientation.
I recently found a discount code through SlickDeals for $10 off the Elecrow 5" HDMI Touchscreen display for the Raspberry Pi. Since the Raspberry Pi was introduced, I"ve wanted to try out one of these mini screens (touchscreen or no), but they"ve always been prohibitively expensive (usually $60+).
This screen hit the right price (even regular price is $40, which is near my "okay for experimentation" range), and I picked it up, not knowing what to expect. I"ve had mixed experiences with Pi accessories from Amazon, and had never tried a product from Elecrow.
The display is pretty solid, and comes well packed in styrofoam with four standoffs for mounting, a cheap plastic stylus, and a male-to-male HDMI daughter-card. Getting the Pi onto the board is easy enough; I used one standoff through one of the Pi"s mounting holes (on the side with the HDMI plug), then seated the Pi directly on top of the GPIO slot on the display board, so so the HDMI ports would line up perfectly on the other side.
The Elecrow officially supports the Raspberry Pi 3 model B, but I tested it with a 2 model B as well. I didn"t try it with a B+, but the hardware layout should work, so at least the HDMI display would work correctly (not sure about the touchscreen controls). The way the hardware is laid out, you seat the Raspberry Pi directly onto a GPIO socket (it takes up the first 13 sets of GPIO pins—pins 1-26), and then there"s an included HDMI male-to-male daughtercard that slots in nicely to connect the HDMI output of the Pi to the HDMI input on the display.
There"s an extra OTG USB plug on the display if you want to give it a separate power source, but if you plug it straight into the Pi"s GPIO, it will leech off the 5V connection. As long as you have a good 2A power supply for your Pi, though, you shouldn"t have to worry about supplying independent power to the display. In my usage, I only saw the overvolt indicator every now and then (just like I do in normal usage of the Pi 3, since it uses a bit more power than a 2!).
When I first booted the Pi attached to the display, there was a large white area on the right, and only the left portion of the screen was being used by the Pi (it was only using 640x480 of the 800x480 display). To fix this, you have to set a few display options in the configuration file the Raspberry Pi reads during startup to switch certain hardware settings.
Besides being a 800x480 HDMI display, the Elecrow also has a touchscreen overlay that allows simple one-point resistive touch detection on the screen. Note that at best, resistive touch is not nearly as responsive and intuitive as capacitive touch detection, which you"re likely used to on any recent smartphone or tablet screen. But something is better than nothing, when it comes to building simple UIs for "Internet of Things" devices or other fun things.
I tried to find some kind of downloadable driver for the XPT2046 touch controller, but didn"t find a lot of helpful information. Elecrow"s Wiki has some helpful information, a link to a setup PDF, a link to some configuration examples... but some of this seemed to be formatted incorrectly (likely due to bad copy/pasting or PDF formatting), so ignore that info and use this process instead (all commands run from the Terminal app):
For ~$30 ($40 without discount), I wasn"t expecting a mind-blowing retina display with excellent glare-reducing coatings and contrast. But I do expect no dead pixels, and at least a crisp, vibrant picture when looking straight on. This screen is "good enough" in that regard, though viewing angles aren"t too great; side to side is okay, but looking down from above or up from below results in a bit of a washed out picture. Also, there is no antireflective coating on the screen, so wherever you use it, you need to be aware of nearby light sources.
So, to summarize the review: this is everything I expected out of a sub-$50 display. It"s nothing like a high-end smartphone display with capacitive touch, so if that"s what you"re expecting, you"ll have to look elsewhere. But if you just want a small display that mounts to the Pi easily and is more affordable than the Raspberry Pi Foundation"s own 7" touchscreen, this is a great buy!
This LCD can support Raspberry Pi OS / Ubuntu / Kali / Retropie systems. When the LCD works on systems such as Raspberry Pi OS, the resolution must be set manually, otherwise, it will cause an abnormal display.
8) Connect the HDMI interface of the LCD to the HDMI interface of the Raspberry Pi, power on the Raspberry Pi, and wait for a few seconds until the LCD displays normally.
If you use the Buster branch system, you can use it according to the above configuration. But if you are using the Bullseye branch system, you need to modify the default KMS driver to FKMS driver for displaying the system desktop normally.
2. Input command xinput in the terminal, and check the touch ID of the main monitor. (There should be two IDs, you can touch displays to check which is the main one);
After execution, the driver will be installed. The system will automatically restart, and the display screen will rotate 90 degrees to display and touch normally.
( " XXX-show " can be changed to the corresponding driver, and " 90 " can be changed to 0, 90, 180 and 270, respectively representing rotation angles of 0 degrees, 90 degrees, 180 degrees, 270 degrees)
