Hello!
I noticed the other day that my installation of LibreELEC is showing a max resolution of 1280x800, and verified this is the output resolution on my TV. I have a 4K TV and 4K capable receiver so I would love to try to get this working. I went through the steps to create a custom EDID and specified 3840x2160 in the config file and it is still showing the max 1280x800 resolution.
I am running LibreELEC on a Surface Go 2, then to a USB-C dock (for HDMI and Ethernet), connected to a Denon receiver, then to an LG G3. All of these devices support 4K and was previously able to output 4K with W10 so I don't think this is a hardware limitation. Any help would would be appreciated!
