Hi.
A newbie here although a very long time happy user (but not very techie).
I have a new GMKtec NucBox G10 (AMD Ryzen 5 3500U) on which I've installed Libreelec 12.2.0 (seemed the most stable at the time but......!). Outputting to an LG TV.
I have an issue trying to reduce the display resolution from 3840x2160p to 1920x1080p. I'm trying to do this because playback is suffering (e.g. audio only) at the higher resolution. But if I do this and then reboot the Libreelec splash screen appears, freezes, and then a small window with Libreelec in it appears in the top left of the screen.
Hours of AI (not) assisted (not) help has found no resolution. The best I can get SSH to do is reboot without the error but then the display resolution changes back to 3840x2160p.
Am I correct to be trying to reduce the resolution to improve playback performance? If so, how can I do it? Would a more up to date Libreelec version help (there was some issue doing this which I've forgotten given the day I've had!)? Is this an issue with this hardware (I've always used Intel before)?
I tried a forum search but it's hard to come up with a good search term.
Cheers
