Resolution

I have an issue with the default EDIDs that are provided. I have need to be able to run at 1920x1080 30HZ but I can't figure out how to get any EDIDs to work. I copy/pasted the edid-decode hex from a monitor that is listed at 1920x1080, but it keeps coming back saying 3840x2160.

Any help that can be provided would be greatly appreciated.

I will try to make a 1920*1080@30FPS EDID and I will reply you if any progress is made.
