Same here, however in the config file I changed V4 to V3 and it is readable now.

Thanks but did not do the trick for me.

I have the same hardware as you, but I don't have this problem. Are your headers properly soldered - no cold solder joint for example?

Not that i know. Pwnagotchi works fine.

Can confirm. Had the same issue, this fixed it.

switchin from v4 to v3 and then rebooting also fixed it for me took a long time to boot after the change tho (it might be because i have the 3 colour v4) because i see some red details now in the display
