Waveshare 3.4inch HDMI Circular Touch Display, 800x800, IPS, Up to 10-Point Touch for Raspberry Pi 5 /for Raspberry Pi 4B /for Raspberry Pi 3B+ /for Raspberry Pi Zero 2 W/for Jetson Nano for Mini PC

I *really* want to like and use this display - the construction looks and feels high-quality, it has a great weight to it, and seemed to be packaged well but so far I have not been able to get it to work, at least with my Raspberry Pi 3 Model B+ or Zero W (both of which are listed as supported). Contacted the seller asking for any sort of troubleshooting guide, was sent an "electronic manual" - a one-page PDF that included the instruction to "Connect the LCD to the PC via the HDMI interface, and Windows will automatically recognize the display function." For the price I was looking for something that I could get running either quickly or painlessly. So far this has been neither, but when support updates me on the ticket I submitted (and I have the free time) I will troubleshoot some more and update this review.
