             Bug #: 45968
           Summary: [RADEON:KMS:RS780:HD3200] l 2560x1440 detected by
                    monitor as 1280x1440, every second pixel missing
    Classification: Unclassified
           Product: DRI
           Version: unspecified
          Platform: Other
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: ranma+freedesktop@tdiedrich.de


My new monitors native resolution is 2560x1440 which requires dual-link.
I'm using the DVI-Cable that came with the monitor.
KMS/Xorg claims to have set the resolution to 2560x1440.

Debian/unstable
Linux 3.3.0-rc3 (built from source)
libdrm 2.4.31-0 (built from source)
xserver-xorg              1:7.6+11 
xserver-xorg-video-radeon 1:6.14.3-2 (tried building from source, had the same problem)
Gigabyte GA-MA78GPM-DS2H

As a workaround, custom 2560x1440@30 and 2560x1440@24 modelines work, but seems very suboptimal...
