Low resolutions in Win NT.

[qwert]

I recently installed Windows NT on a computer using a AGP Viper 770. The problem is that I don't get a lot of resolution the maximum resolution that I get is 800 by 600 in "true color." I followed the directions for the drivers' installation carefully. My computer is PIII with 128mb of ram. The monitor is only few weeks old, and it supports high resolutions and refresh rates. Any suggestions, comments will be
greatly appreciated.

Truly very yours,

Your actually trying to change the resolution? And either the choice is not there or the resolution doesn't switch?

MS's knowledge base posts references to this with a Matrox and a ATI vidcard drivers. It may be true for the driver version you have. Maybe. Check and install the lastest driver from Diamond www.diamondmm.com/products/drivers/viperv770.html if needed.

The service packs are also life savers. Have at least SP4 installed. SP5 is better.

Thank you for your responce,

The setting does not have any higher resolutions available. I can lower the resolution if I want, but I am already using the highest resolution listed. Also, I used the drives that currently posted on dimond's web site to install the card. I had the same problem when I tried to install Win NT on a computer with a Vipper 550 AGP. I was thinking that it might have to do with the fact that is using the AGP port since Win NT only resently added support for that kind of device.

Thanks again,

Which service pack do you have installed?

I've installed a V550 and a TNT2 Ultra in two seperate systems with NT SP5 with no problems. If you have SP3 get SP4 or 5. Then reinstall the drivers.

I have SP4 installed. I am going to install SP5 and reinstall the drives. Hopefully that will do the trick.

Thanks
