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

I'll update this review if I ever get it working. I bought it to use with Raspberry Pi 4 with Raspbian Buster. It had great reviews so I figured it would work right away. I was wrong. No matter what I try, it won't work. I get a "No Signal" window in the middle of the screen. The description states that it works on Raspberry Pi 4 without additional drivers. This couldn't be further from the truth. I've tried everything I can think of (and lots of suggestions online). Nothing seems to work. I left a question and am hoping that the manufacturer or someone working with the Pi 4 will answer it with some guidance. Until then I can't give more than 1 star.
