Description

If we get no EDID, try also VESA flatpanel extension.

I did add the flatpanel query for sake of completeness, I do not have any such hw to actually get answer for information request, but it also does not interfere my other test systems (we either get EDID data or fall back to default resolution).

About high resolution displays; the available documentation specify values for resolution as 12-bit integers, so the max resolution is 4095x4095. That will work for 4K, but 5K and 8K would not fit in. Currently, I have no information how to handle displays > 4K.
