Review on UCTRONICS Raspberry 1024×600 Capacitive Touchscreen 7", Portable, HDMI, HD by Joachim Stephenson

Mine has worked out a box with a raspberry pi4. You need to connect the touch function to the pi4 with a USB cable for it to work. The picture quality is excellent. 4k videos look great on it. Retropy games are pretty decent once you set the resolution. It's hard to find an enclosure for it, even a 3D printed one, as the HDMI and USB layouts are different from most 7-inch displays.
