When checking the Advanced Display Settings on can click on the "Display adaptor properties 
for Display 1". In that window one can click on "List all modes". In this list the 
640x480 mode does show up.

The 2048x1152 does not show up anywhere, with edid on as well as when edid is 
off. So my guess is that this resolution is just not supported by the Windows 
Basic Display Adapter?
The same applies to the resolutions in the lines starting with VIC, though I 
did not check if the 1920x1080 is 60 or 50 Hz.

If there is anything else that I can do, let me know.

All the best,
Aaron
