[mythtv-users] nvidia colour problems with 185 drivers (mythTV)

[David Madsen]

I believe this was caused by a change in the NVIDIA drivers in how it
interprets the value of hue.  The older drivers expected the default
value of hue to be at 50% of max value, while the new scale has moved
the default to 0.  Nvidia-settings would fix this for you when you ran
it, but MythTV itself may be setting the hue value to something the
old drivers expect when you run.

You can try adjusting the hue playback controls within MythTV to see
if that fixes your problem.  I believe there have been some changes
recently in SVN to fix this, but if you are running from a .21 version
this is likely to be the problem.
