Tried the same Deza 2 experiment, but this time with the XRGB2+. The funny thing about the 2+ is that the EDGE sometimes sees this correctly as VGA.
Here is the first shot where the EDGE recognizes the 2+ as YPrPb (same as the XRGB-3):
And here is VGA:
I wouldn't call that much of an improvement... Actually I don't see any at all. The blue and red colors are still messed up like always but this time the picture is squeezed from 720x480 to 640x480 and it's extremely noticeable.
It looks like it wont solve this problem just by making the EDGE detect the correct colorspace. Actually I'd rather have it detect it as YPbPr, like it does now, and get an image with correct pixel width.
Perhaps it could work somewhat correctly if we could just manually change the input colorspace to YPbPr 444? But I don't know shit about colorspaces and whatnot, I'm just guessing
The only positive thing about the correct VGA detection was that I could actually move the picture horizontally a bit further using the XRGB2+, before the colors got messed up... That's also a very strange EDGE problem :/
