A similar patch as done in [1]
commit bc42aabc6a01b92b0f961d65671564e0e1cd7592 Author: Adam Jackson ajax@redhat.com Date: Wed May 23 16:26:54 2012 -0400
drm/edid/quirks: ViewSonic VA2026w Entirely new class of fail for this one. The detailed timings are for normal CVT but the monitor really wanted CVT-R. Bugzilla: http://bugzilla.redhat/com/516471 Signed-off-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>is needed.
I sent a patch to the dri-devel list [2].
It is strange though, that Windows despite using EDID according to Adam Jackson supposedly gets this right, that means gets a working image on the monitor.
Testing another TV (LG SL80), I had the same problems with, with a Lenovo T60 instead of the ASUS EeePC 701 4G, it worked fine (bug 53544 comment 5) [3]. Therefore the problems seems to be something else and needs further investigation. Please do not commit this patch.
