display problem : tearing


Hello,
I installed Ati proprietary drivers, I'm on Debian Squeeze.
When, for exemple, I scroll in a web browser, the page is "tearing". A vertical line moves from the bottom to the top of the screen or from the top to the bottom, and the web page loads by following this line. This also happens if I move a window.
I supposed it cames from horizontal and vertical synchronization, so I edited my xorg.conf file and added the horizSynch and VertRefresh values (I founded it on http://www.lcd-compare.com/moniteur-...-W2361V-PF.htm). But it didn't change. Any idee ?
Here is my xorg.conf if it cans help :
Code:
Section "ServerLayout"
        Identifier     "aticonfig Layout"
        Screen      0  "aticonfig-Screen[0]-0" 0 0
EndSection

Section "Module"
EndSection

Section "Monitor"
        Identifier   "aticonfig-Monitor[0]-0"
        Option       "VendorName" "ATI Proprietary Driver"
        Option       "ModelName" "Generic Autodetecting Monitor"
        Option       "DPMS" "true"
        HorizSync    30.0 - 83.0
        VertRefresh  56.0 - 75.0
EndSection

Section "Device"
        Identifier  "aticonfig-Device[0]-0"
        Driver      "fglrx"
        BusID       "PCI:1:0:0"
EndSection
Section "Screen"
        Identifier "aticonfig-Screen[0]-0"
        Device     "aticonfig-Device[0]-0"
        Monitor    "aticonfig-Monitor[0]-0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
        EndSubSection
EndSection
Thanks for help.

Just open the Catalyst Control Center, go to Display Options and activate the Tear Free function.

The Tear Free Function is activate. I think it's more a refresh problem. When I look a video, it's jerky too.

Try reducing the '83' figure in this line

Quote:
HorizSync 30.0 - 83.0
Drop it in units of 5 or 10. Unless you have an absolutely massive monitor you can get away with less than that. That's 83khz. Your tv does 15.625khz (PAL) and a little less in NTSC
