Help! I can't display 1920x1200 w/ DVI cable on my 24inch

I just bought a BenQ 24 inch FP241W monitor and when I connect my computer with VGA I can display the monitor's native resolution of 1920x1200 but I can't display this when I connect with a DVI cable (the screen just goes blank for a few seconds and reverts to a lower resolution when I try).

Can anyone tell me why this is?

I have the latest driver's for my monitor and graphics card.

I guess there is a chance my graphics card can't display 1920x1200 via a DVI cable, but its a good graphics card so I don't think this is the problem.

These are the specs on my computer:
-Mainboard ? ASus M2N-E
-CPU - AM2 Athlon 64 3200+
-Video Card - Sapphire ATI Radeon X1600 Pro PCI-Express 512MB
-Memory ? DDR2 2 X 512MB
-Running - Windows XP Professional

Thanks for any help!

Contact ATI and see what they say.

In the past, when I contact them they seem to be helpful.

Graphics card's TV resolution

In reply to: Help! I can't display 1920x1200 w/ DVI cable on my 24inch

is 1024x768 per Sapphire web site. So as you indicated "I guess there is a chance my graphics card can't display 1920x1200 via a DVI cable" and that appears to be the case. While I was at Sapphire's web site I looked at other cards from them and saw that there were no cards from them with a higher TV resolution than 1024x768. I had to make the assumption that DVI resolution = TV resolution. I maybe reading it wrong, I?m just making a guess at it. I would email/contact Sapphire to confirm this. Maybe they can tell you more.

DVI is 'Digital Video Interface'

In reply to: Graphics card's TV resolution

With a good video card the DVI should support the same resolutions as the analog. I once had one that wouldn't, RMA's it and the replacement worked both at full resolution.

The wide scree resolution may be the prooblem. That is NOT exactly a TV resolution although it makes the pictures ratio fairly close to TV.

I suugested ATI because the video chip is theirs and they might have better drivers for it.
