Very Strange Problem , fixed..Resolution on Monitor

post #1 of 2
Thread Starter 
Hey guys , this is if by anychance some unlucky sole bumps into this problem , I found no answers on the internet.....soo heres my story...



I recently purchased a 24` Monitor , I plugged it into my PC , and the max resolution the monitor would go would be 1920*1080 (Windows would let me go to 1920*1200 , BUT the actual monitor would not go beyond 1920*1080 , resulting in the desktop extending beyond the monitor) , but it was rated for a max resolution of 1920*1200.......

I tried a hole bunch of stuff , tried the scaling in nvidia control panel , tried powerstrip , made my own driver for the monitor , tried to change the Edid on the screen etc...nothing worked.... , and I then tried re-installing the GPU drivers , When my graphic drivers were uninstalled , the monitor worked perfectly , was at a resolution of 1920*1200.......

thus , one could safely think to themselves that their is no hardware fault , as it works fine right now (no nvidia drivers installed) , however upon installing the forceware drivers (never made a difference which version) , I ran into the same problem , max resolution would be 1920*1080......and if i made it 19200*1200 on windows the desktop would extend......

I was convinced that this is a software problem , as this problem only happened when I installed the drivers.

I contacted Acer , and they got back to me very very quikly , this is the reply I got after explaining my situation and a few other emails :

Hi,

Are you running vista found this on a thread on nvidia website seems the vista drivers from nvidia are a bit buggy a lot of people are experiencing this problem makes me want to buy an ATI 3870 X2 but i hate ATI:

I guess you've run into the same problem I and some other people have been frustrated by since Vista came out.

Basically, it seems like something in the Vista drivers changed, ending up with the monitors not being recognized as Plug&Play components, which in turn forces the drivers into some kind of safe mode limiting the resolution to 1024x768. I've had this happening to me with a 8800 GTX and my two TFTs, too. One isn't recognized at all, the other one (I guess on the primary DVI port) gets the "safe mode" treatment.

From my own testing, the cause is almost certainly in nVidia's Vista drivers', though, as the problem doesn't happen with the same system under XP (TFTs recognized correctly), and it doesn't happen under Vista using an ATI-based card. (TFTs also recognized correctly) It also is monitor-specific, as I could test with a new Samsung 205BW a couple of weeks ago, and it worked fine with the nVidia card and drivers.

Your options, alasly, come down to either hoping for nVidia to eventually rectify the problem (but after over half a year, there's much hope left here), or changing your system in one of two ways: ( a ) buy a new display, ( b ) get a ATI-based graphics card.

I know this is probably really frustrating, but there's no other fix at this point.

soo after gettin that email i just felt great....searched all over the internet and found very similar problems but no solutions....

anyways , I was using a DVI cable , I thought to myself , let me just try using a VGA cable.....now , it shouldent make any difference , as with no drivers installed the DVI did work fine....but i was just pulling strings here , and thought maybe it might work......


believe it or not , using a VGA cable , and it works fine , when I set my resolution to 1920*1200 in windows , the monitor scales perfectly........


I still dont understand how this solved my problem , as the drivers were definitly causing the problem..... , i tried a different DVI cable later on and the same thing......its like the drivers dont like a DVI cable , despite the fact that the connector im using right now is a DVI convertor on my card , soo essentially Im still kind of using a DVI.........


hope this helps anyone with a similar problem , took me 3 days....not bad goin

Screen wont go above 1920*1200
Screen wont go above 1280*1024
Screen wont go above 1600*1200
(just added this in soo it shows up in a google search)


peace
