Interesting.  Seems Windows caches the list of resolutions (or the edid
blob) somewhere in the registry instead of loading it on every boot.
I've seen simliar behavior with usb device info.

[ something for the 5.1 release notes I think, thanks for testing this ]

That still leaves the question open why the list of resolutions is that
short  It should be more like this:

# qemu-edid | edid-decode | grep @
  640x480@60Hz
  800x600@60Hz
  1024x768@60Hz
  2048x1152@60Hz
  1920x1080@60Hz
    VIC 101 4096x2160@50Hz 
    VIC  96 3840x2160@50Hz 
    VIC  89 2560x1080@50Hz 
    VIC  31 1920x1080@50Hz 

Seems windows filters out a bunch for some reason ...

take care,
  Gerd
