2048x384 resolution monitor detected as 800x600...

I'm having GREAT difficulty driving a monitor with a native resolution of 2048x384 at 60Hz over DVI... (Yes that is the true native pixel resolution, no mistake)

I've tried 7900GTX and 8800GTX under XP and Vista, but nothing works. Windows reports the screen as 800x600.

The EDID information is being received correctly, and the correct timing values are set up (checked using XP, 7900GTX, and PowerStrip) but Windows just won't accept the resolution.


Does anyone have any similar experience, and hopefully a fix?

  1. you have a 16:3 monitor?!?!

    huh 8O
  2. Yes I do. Really. Custom built. Quite large...
  3. Now that's a incredibly odd resolution!
    Tell us the monitor model.
  4. I'm guessing its a plasma screen? If so be aware that the static image you'll have alot of the time as a monitor will ruin the screen with burn in...

    384 vertical pixels is a horribly low number for a computer screen :/
  5. You stated it is being detected as an 800 X 600...my guess is that it is being properly detected (you said EDID information was being received correctly); it's just that Windows doesn't know what to do with the odd resolution so it is defaulting to 800 X 600. Out of curiosity, can you force 512 X 384? Perhaps somebody much smarter than me could edit code to turn this into 3 or 4 virtual displays, placed side-by-side to create a full screen image...just thinking out loud...
  6. Did I mention that the screen is curved? hehe (due to NDA I can't say much)

    Not getting very far... The latest 8800GTX drivers for Vista see the correct resolution, but doesn't show any selectable refresh rates. Popping out from the Nvidia control panel to the Windows control panel, and the resolution becomes -1 x -1. Great.

  7. dumb question.

    but since this is for a commercial application, why not just give nvidia a call and ask their support directly?
  8. Your card has probably never seen that res before in its life, and was never programmed to do so. So it has an error.

    Bummer for the man with a horizontal slot for a monitor. Does it wrap around your eyes like that thing from Star Trek? That would be some cool stuff.
