DVI issues

Submitted by uncleck on Thu, 2008-09-18 17:18

As I said, I have gotten a 4:3 AR (aspect ratio) monitor to work.  My widescreen monitor works with DVI in XP, but not in Vista.  And it is definitely a driver issue - ATI has admitted as much.  Just look in the AMD forums, for instance.

Apparently, no matter what settings one uses in Catalyst, upon reboot the driver defaults to the highest values for both the screen resolution and refresh rate in the monitor's EDID - even though the highest refresh rate is for lower screen resolutions and the highest screen resolution only works with lower refresh rates.   My 4:3 ViewSonic, which does work, has for its highest EDID values: 1280x1024 @ 75Hz.  And it works at those settings.  On the other hand, my widescreen monitor has 1920x1200 @ 60Hz all the way down to 1280x1024 @ 75Hz.  (Highest res-lowest refresh and lowest res-highest refresh)  But when Vista starts, the DRIVER defaults to 1920x1200 @ 75Hz (highest res-highest refresh), and therefore, I get no picture.  So yes, one could say that it is my monitor's fault - for having more than one screen resolution and refresh rate referenced in its EDID.  But the fact remains that ATI's driver is unable to correct for this.  Something that I have never experienced with any nVidia driver.

DVI and ATI

I am running a Viewsonic LCD monitor with DVI connection and it works fine with my MSI OC Radeon 4870. I would guess there is something wrong with your monitors DVI connection or your individual cards DVI port if your DVI is not working. It's definitely not a driver issue.

What is a driver issue I wish they would have addressed is the problem running Battlestations Midway. the atikmdag driver does not get along with BSM and crashes the game 2 seconds after gameplay launch, with a display driver not responding error. This does seem to be pretty wide spread based on the posts online and it doesn't appear anyone with a 4800 series card is able to play BSM currently.

No fanboys here

I have gotten a 4:3 AR monitor to work with DVI in Vista (ViewSonic 922), but not a widescreen.  I am curious as to what motherboards you, who have not experienced the issue, are using.

 BTW, people who cannot spell should be careful applying the word "stupid" to others.  (I'm just saying. . .)

Still haven't fixed major issue...

But ATI, in its infinite incompetence, still hasn't fixed the DVI issue with Vista:

In short, all 3800 and 4800 series cards seem not to work with DVI connections in Vista.  It is definitely a driver issue, because DVI works in XP and VGA connections work in Vista.

Apparently they don't see this as a problem.  I wonder how many repeat customers they are losing because of this.  I, for one, will be returning to nVidia for my next graphics card purchase.  In fact, ATI's failure to even address this issue has soured me on ever using another of their cards in the future.
