AMELIN HDMI to MIPI Interface Driver Board for 1.39 inch 400x400 Round OLED

Product was received as advertised in only a few days which was great. There were a couple small smudges on the screen but light brushing with a q-tip took care of it.Display clarity and brightness look great so far. I'll need to do some simple graphics tests next and can share.In case you're trying to use this on a raspberry pi, you'll need to set the correct timings as the pi doesn't recognize the detailed timing descriptor. A windows PC figured it out right away, so I'm going to blame the raspberry pi.In your /boot/config.txt, simply add the following line:hdmi_timings= 400 0 400 20 400 400 0 20 4 12 0 0 0 60 0 31000000 0Also, if you made a custom user you'll need to add it to the video group:sudo usermod -aG video YOURUSERNAMEHowever, you should probably add every group the pi user is in. You can find that out with:groups pi
