[LINUX] Poor quality picture via HDMI (NVidia) - mwhwsmith - 2011-03-27
I have a Acer Aspire Revo 3600 (Nvidia ION) running Ubuntu 10.10 and XBMC which I have just installed along with the most recent NVidia drivers. Playback is onto a Loewe Individual LCD panel (1280x720)
I notice that in playback I get a line or discontinuity running horizontally across the screen about halfway down. It is most noticeable when the picture is changing rapidly.
I have been adjusting the various video settings (both in XBMC and in te NVidia X Server) and have adjusted the buffer to 512MB in the BIOS. However, I can't seem to get rid of the distortion.
Any ideas?
Many thanks

The kind of distortion you are describing is usually called tearing.
Try to enable vertical sync.

And disable composite.
/etc/X11/xorg.conf:
Code:
...
Section "Extensions"
Option "Composite" "Disable"
EndSection
