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...
