KDS AV-7TF 17" + SDR GeForce 256...what's the max resolution I can run?

[NFS4]

I've been trying to hit 1280x1024 but all I can seem to get is 60Hz...Is that all that this monitor or vid card can do?

Right now I'm at 1152x864 @ 75Hz

That would be the monitor, I've seen a Guillemot Prophet SDR do 1600x1200 @75hz. Is it an older monitor? I'm not familiar with KDS...

Did you install the latest inf for the monitor?

 

[NFS4]

I got the drivers from KDS...they're Win95/98 drivers though (I run Win2k).

Does anyone know where can I can get Win2k drivers.

The KDS AV-7TF is a 70Khz horizontal scan frequency monitor, thus it can only do a maximum of 65Hz at 1280 x 1024 resolution. It will do 85Hz at 1024 x 768. If you want to run higher resolutions and refresh rates, you need a monitor with higher horizontal scan frequency.

Good Luck

Jim,
While I don't know how to exactly figure maximum refresh rates/resolutions, I do know all monitors have a certain bandwidth cap which determines the max resolution/refresh rate the monitor can handle. Most all the clone FD Sony monitors have a 220MHz max bandwidth, sometimes called dot clock, anyway, this should allow 1200x1600@85Hz. My CTX Sony clone allows this resolution/refresh rate using a eVGA GFMX which has the same RAMDAC as the GF.
Here's a page from the site you link in your sig that list the specs for the KDS monitor.

As for NFS4's problem - check to see if the proper monitor is displayed in the display properties pannel, if so then it's most likly a Nvidia driver issue with Win2K. You can also try using a monitor driver in the Windows driver data base if Win2K has them - don't know, haven't tried it.

Sorry about the link, can't get the code to work right - M

Hardware resolution is ((hor. screen size in cm)/ (hor dot pitch in mm))*10
To make it easy for a e.g. 19" (17" visible) dotpitch 0.30


4*sqrt((17*2.54)^2/25)/ 0.30 * 10 = 1150 pix !
