Created attachment 60467
  --> https://bugs.freedesktop.org/attachment.cgi?id=60467
drm output from 'dmesg' and output of 'xrandr --verbose' to hopefully describe
my setup

Since some time now 1920x1200 output on HDMI port of my nv50 based card shows
two black bands on the left and right side of the screen. It's clipping (i.e.
pieces of the desktop are not drawn), resolution seems to be correct. 

bisecting of the linux kernel got me here:

b2337f2333c0bdefc9b230da17ed7188e4eb7f6c is the first bad commit
commit b2337f2333c0bdefc9b230da17ed7188e4eb7f6c

    drm/nouveau/hdmi: enable sending of avi/audio infoframes

    Signed-off-by: Ben Skeggs <bskeggs-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

:040000 040000 edc0d0e6f57362c38edb0845cf19ee076a045f0b
364748b5ea73b322991331396fb218d8afd65fe7 M    drivers

And indeed taking out these changes from the current 3.4.0-rc4 kernel seems to
solve my problem.

Seems this enabling of avi/audio infoframes has some bad side effect for my
hardware.

Found that my monitor is one of a number of types that assume HDTV when they
receive audio infoframes:

Sure did, much cleaner than my dirty commenting out of the infoframes.

Sorry for missing this request. Is it still relevant for me to go test it?
(Have converted to triplehead ATI card and Radeon open source driver with it's
own set of problems since).

Closing issue since the original reporter no longer uses the hardware. And it
sounds like the screens are buggy, not nouveau, and the fix is to massage their
EDIDs, which is what the patches in the redhat bugzilla have done. Hopefully
they'll go upstream if they haven't already.
