Vertical refresh visible in animations
Description
The horizontal refresh is not synchronized with the application so that the
vertical refresh
is visible in animations. The effect are horizontal lines in fast animations
or video playback

Affected Cards and Drivers
Different

Solution
I don't know why the nvidia drivers do not get this managed. The x-server
has a mechanism to
report a horizontal sync for applications. However the following solved the
problem:

With the nividia-settings tool generate a settings file that includes the
following lines:
 0/XVideoTextureSyncToVBlank=0 0/XVideoBlitterSyncToVBlank=0
Note that the settings are switched OFF The configuration can be found in
the "X Server XVideo Settings"
panel and is called "Video Texture Adaptor" "Sync to VBlank".
Tambien Sync to display device ponerlo a (*) TV-0

The settings have to be set with every start of the x-server e.g. by adding
nvidia-settings --load-config-only to the xserverrc
(/etc/X11/xinit/xserverrc)

Subject: Re: [Freevo-users] TV Out problem



I use a Via SP13000 with their built in via unichrome chipset and see
exactly the same thing!

I get about 6 to 8 vertical lines down the image, I assumed it was a
specific problem with the via chipset or similar.

I have seen this running Fedora Core 5 and 6
