DVI Problem almost solved, need a little more help

As some of you know I am having a few problems trying to get my new flat screen monitor to update smoothly when using Blitz3D\+ in windowed mode using a DVI cable.

Well after trying several older drivers (NVidia) I have found one that actually seems to resolve the problem but the trouble is that it doesn`t support my monitors optimum resolution, 1440x900, it only goes up to 1024x768. The feature to add custom screen resolutions was not in this driver or for quite a few after (they don`t work incidentally as they have the same screen update problems as I was getting before.)

My question is are there any other methods to add more screen resolutions to the older NVidia drivers if they don`t have the custom screen resolution controls? I have tried to install the monitors drivers thinking that this would do the trick but it hasn`t. The drivers say that my monitor supports 1440x900 but I cannot select that resolution as it doesn`t go that high. My card supports a higher resolution than 1440x900 too so I`m not sure why the driver doesn`t include them.

If anyone could help that would be great as I think that this may cure my update problem (fingers crossed.)

BTW the driver that I am using is 30.82, a really old one but it seems to work quite well.

That's odd, when I plugged in my new screen (DVI) I just had more screen res' available on the display properties, shoved it up to 1680x1050 and everything has worked fine.

This may be a ridiculous thought, but does your monitor have both VGA and DVI inputs? Can it switch between them by you pressing a button? Does your gfx card have 2 outputs?

Would the loss of quality provided by a VGA signal outweigh the ability to be able to do Blitz smoothly?

Can you see where I'm going with all these questions? ;)

I know what you are saying and have infact plugged my VGA cable back in, the hassle is not worth losing Blitz over. Sorry to keep bothering everyone with this.

Thanks anyway to all that helped.

You might be able to cobble together a modified monitor.inf file to explicitely specify the resolution you want in case the video adapter doesn't understand the monitor properly.

also, back in the day I was able to get my Voodoo3 to run some odd resolution at 100Hz after finding the place in the registry where it stored the available resolutions, and manually adding some. By default it would only go to 60Hz on some resolutions, but after the registry change I also had the 85 and 100Hz available for selection -- and they actually worked. (the monitor had an information option, where it would display the refreshrate it ran at)
