    Hi, once again I come with an issue with my new computer that i did not have with the old one. When watching videos part of the image can become lined. Usually happens during fast movements or when the camera cuts to another perspective. And it also seems to like doing it more often to the colour red.

    I took a couple of screenshots, first one from a clip on youtube and the two bottom ones from a video on my computer. It was not the best screenshots to show the severity of the issue but since the lines are only the for a fraction of a section I had a hard time timing the pause.

    Sadly it is highly distracting with these lines, since it has a flcikering effect to the eye and is just so annoying.

    I am not sure I posted this in the right section, simply because I do not know what the problem is.

    I am very grateful for any assistance in this issue.

    Looks like Pixel Persistence or what they use to call ghosting in CRT days.
    The pixels turn off slowly leaving a ghost image.

    This site might explain it for you and the software can be used to test your display:http://www.prad.de/en/monitore/testsoftware/pixperan.htmlHave a very nice day.:)

    I thank you for trying but alas that was not the issue, had no problems during the tests.

    And also would it be captured on the screenshots if that was the problem? I mean because doesn't the screenshot capture the image the computer sends out and not the image that is displayed by the monitor? That seems to be the most logical way for it work in my opinion.

    And I used this monitor with my old computer and these was not any issue there.

    You're right, this has nothing to do with your monitor but (most likely) with your videocard and/or it's drivers. Looks like a case of lousy de-interlacing to me. Try installing the latest nVidia drivers for your videocard. If that doesn't fix it, you might have to tweak some settings in the driver control, but I can't help you there since I haven't had an nV card since the Geforce 4 series.

    I have the latest drivers installed aswell, maybe just have to wait untill a new set is released to see if it is improved then.

    And when it comes to settings I have been playing around abit there, but I am kinda a novice when it comes to it so I am not quite sure what to change that could affect it.

    Yep, he and you are right, wasn't thinking screen shot, oh well, sorry.:slap:

    Just thinking though, have you tried v sync off and on. I don't use NVidia either.

    Just tried fiddling with v sync, no change though.

    Is it just me or does the Nvidia control panel feel incomplete copared to ATI's?

    Try uninstalling your drivers and delete old folder..then reinstall another driver to see if you have issues with the other driver.

    I tried today with the drivers that just got released, sadly the problem is still there. Somehow it seems to happen more to the colour red than any other objects.

    Could it be caused by codecs? but that does not make much sense when I also have the problem on youtube since as far as I know it does not use the divX/Xvid/ac3 codecs I have installed.

    One more thing is that it seems to happend more in Windows media player than in media player classic but the image is alot sharper in windows media player than media player classic.

    So anyone have any more ideas? It really ruins alot of the fun in watching shows since i get so irritated by the issue.
