starting with 2.6.36 my monitor detects a resolution of 1920x1199 instead of 1920x1200. The monitor displays 1920x1199 on its OSD, and as a result, I guess, the display is blurred in the middle section (top to down) - most likely due to stretching applied by the monitor.
I finally got some time to bisect this issue and found 81a14b46846fea0741902e8d8dfcc6c6c78154c8 drm/i915/sdvo: Set sync polarity based on actual mode causes the bug.
And, indeed, reverting 81a14b46846fea0741902e8d8dfcc6c6c78154c8 on 2.6.37.3 or 2.6.38-rc8 makes my monitor detecting 1920x1200 again.
Please note, this patch is part of a 3-series together with: b599c0bca1e08a89a7fc4305bc84f4be30ada368 drm/i915/hdmi: Set sync polarity based on actual mode d6d952689a48375afb97f619f77d548f16d45a92 drm/i915/pch: Set transcoder sync polarity for DP based on actual mode
