The technical term is "tearing". You get this when the screen is  
updated out of sync with the vertical retrace. This often happens on  
cheap LCD screens if the gfx card outputs a frequency not native to  
the LCD panel. Try different refresh rates, 50, 56, 60, 66 and 70Hz.  
Most likely the LCD screen runs at either 56 or 60Hz.


If you still see such problems even with the gfx card outputting the  
correct frequency, then you need to turn on sync on vertical retrace  
for your gfx hardware in xorg.conf.

[vdr] Nasty effect...

[JJussi]

Hi!

Is there setting what "removes" effect where when camera is moving side to 
side straight vertical lines are "divided" to 2 - 4 "zones" (inside zone line 
is "whole") and those areas are at different positions (horizontaly)

Like:

That "cut point" is moving upvard between different frames.

Screen is LCD.  1024x768 60Hz 

Is this something like screen is updated at wrong point (of time), syncing 
issue? Why screen is not updated progressive just before drawing.. Or is it 
so that video card don't know when TV is drawing the picture?!?
