    After months of saving I have just bought my ideal PC:

    AMD 64 FX 55
    2 x GeForce 6800 GT SLI
    2GB RAM
    Viewsonic vp201b

    The problem I have is that when I use the DVI cable with a 1600 x 1200 resolution, I keep getting these random purple coloured pixels on my desktop (XP - the one with the green fields!). There are not many of them (50 - 200), but there is enough to be noticable. They are random, sometimes in isolation sometimes in an arcing pattern. They seem to occur more on a green background and also against the sky. Some of them flash, others do not.

    They are not noticable when using the internet.

    They are VERY noticable when playing half-life 2. (especially in the sky)

    When I use any other resolution they disappear. They are also not noticable when I use the VGA connection at 1600 x 1200.

    To be honest I am very happy with 1600 x 1200 using the VGA connecter, but if anyone knows of a quick fix to enable me to use DVI (especially when you pay so much money you expect everything to work well!) I would be very grateful.

    After speaking to my PC manufactuer's help line, they said that my graphics cards probably did not support the 1600 x 1200 resolution. I find this hard to believe.

    Thanks for any ideas.

    You might want to check yer refresh rate... I dont much care for playing games (specially high end) on LCDs seeing as that most of them have CRAP for refresh.
