           Summary: Add GPU scaling for DVI displays (for R420)

           Version: unspecified
          Platform: x86 (IA32)

            Status: NEW
          Severity: enhancement
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org

I'm using an Apple Cinema Display 20". It has a native resolution of 1680x1050.
No other native resolutions seem to be supported. As the radeon driver does not
support GPU scaling for DVI connected displays (as far as I understood), it's
currently not possible to run other resolutions on this display. Please add
this (IMHO very basic) feature.

Also pleas allow scaling while keeping the aspect ratio of the resolution (i.e.
adding black areas left/right or top/bottom.

I'm running this display connected to a Radeon X800(R420).
