Waveshare 5.5inch HDMI AMOLED 1080x1920 Resolution Monitor AMOLED Capacitive Touch Screen with Toughened Glass Cover Supports Multi Mini PC as Raspberry Pi4 and Multi Systems

OLED works well, still need to test lowering the brightness and touchscreen. Seems well made

The vertical.format of the videomis great! The touchscreen and the screen itself are very responsive and good. If you want to start an open phone/tablet , I'd start right with this screen and the RPi.

I'm now on my fourth 5.5" 1920x1080 AMOLED Waveshare screen for a single project. I'm hoping to run the AMOLED off a Raspberry Pi 3, putting both in a self-designed and -printed enclosure (see picture), which will occupy 2x 5.25" bays. When the screen is working, the whole system is absolutely beautiful, with color and resolution comparable to a high-end smartphone and working capacitance input. Make sure you've properly configured your Raspberry Pi and/or workstation. Details can be found on the Waveshare wiki.I don't know why some people are saying it doesn't do full 1920x1080 resolution. It absolutely does. I can drive 1920x1080 with 90-degree rotation from both the console and Xorg by following the simple instructions on the wiki.Waveshare includes a great little set of bridges. I use two -- the HDMI-to-HDMI, and the micro-USB to USB-A. These are exactly what you'll need for interfacing with most RPis.That's the good. Now the bad: first off, the micro-USB power jack is inconveniently placed. A plug that goes to the left will interfere with the HDMI bridge. A plug that goes straight up will add to the total height, making the system difficult to enclose. You pretty much need a micro-USB plug which turns to the right, and makes the turn low.Much worse is the fragility of the device. The first arrived with a crack, and I got a replacement. I managed to crack the second pretty thoroughly and quickly. The third I treated very delicately, and the screen remains intact. After a few days of use, however, the screen no longer powered on, and plugging in the microUSB makes the green LED flash. The wiki claims that this means the USB power is insufficient, and a 2A 5V DC supply ought be used. I went ahead and hooked up a 2.5A 5V DC supply from a Raspberry Pi, and I get the same green flashing light with no display.I've gone ahead and ordered a fourth, making three that I've paid for. One I definitely broke myself. I'm not sure what happened to that third one; for now I'm assuming I somehow broke it, and thus not returning it, but we'll see how this fourth one goes.When it works, this is a great device. I'd just like to see it work reliably.

very satisfied ! (discard my question asked here, I used another computer and the touch feature worked, probably the usb port with my first computer is not working )

Edit 2: I really liked waveshare for their hardware but now I like them for their response to inquiries and concerns. Giving another star. Their timezone is opposite from mine but they got back to me every evening with updates and suggestions.Edit 1: I'm updating my review because I screwed up. This screen comes in a cardboard box with foam cutouts for shipping. I had not realized that a small piece of foam had logged its self in the hdmi output slot. I was able to very carefully extract the foam using tweasers and bingo! It works.I still have some issues with the screen. It's hands down the prettiest compact panel I've ever seen. The trouble is the documentation. There really isn't any. There is a doc on the wiki for basic trouble shooting like screensaver, touch rotation, etc. Unfortunately there isn't anything regarding the pins. Furthermore, this doc wasn't linked to on amazon and you can't get this panel working for a pi without modifying the config.txt in /boot/ with text from this doc.It's frustrating because I know there have to be pins on here for power, ground, and probably even audio out for speakers. Nothing is labeled though and there isn't documention for pins so I can only use the headphone jack for audio and I'm forced to power via micro usb. That's really restricting when creating a portable design.Still, it's a beautiful display. Easily the best best panel I've even purchased and I've probably bought a dozen at this point.
