Geforce 460 and DVI question

Discussion in 'Nvidia' started by Seasidepeter, Mar 31, 2011.

    I recently bought and installed a Palit Geforce GTX 460 1Gb - the sonic
    platinum edition. While the card powers my Relisys tl795 r-u monitor
    brilliantly, neither DVI ports work properly. I get a bright green
    background to everything.

    I've tried three different DVI cables with the same result.

    My monitor worked perfectly well from the DVI port on my previous
    Geforce 5600 card.

    Before I go through all the hassle of sending the card back - does
    anyone have any experience of the problem? Could it be the monitor?

    If the monitor worked with your old card, it's not the problem.

    I agree with Tom. It sounds to me like you've narrowed it down to bad DVI
    ports on your new vid card.

    Have you tried updating the card BIOS? I see Palit has one specifically for
    your card to fix some compatibility issue.

    Someone here may be reporting the same thing - more modern video
    card, DVI output, TL795. It would appear, something happens to
    the monitor, after it is run via VGA. Then DVI is screwed up afterwards.

    The VGA port apparently still works normally. Weird.

    I'd probably start with Moninfo, and see if the EDID still works.
    Perhaps the EDID got corrupted ?

    The EDID should work, whether you're connected via VGA or DVI.
    Communication with it, is serial, via a couple pins on the cable.

    I wouldn't trash the video card just yet.

    Thanks for the input - checked the BIOS upgrade and I get "no need to
    update your BIOS".

    I'm taking the machine to my friendly local repair shop, which has
    offered to try the card on different monitors. I'll post any results..

    <snip moninfo report>

    In case it helps anyone else - the problem was the monitor. I now have a
    sparky new widescreen running off the DVI, and my trusty old Relisys
    woreking as a second monitor from the VGA port.

    Actually, I don't know why I haven't done this before...
