Refresh rate probably.

Just tried changing it. That didn't help.

I had an issue with the Diamond Stealth card I used previously (flickering) so I bought this other one, an APAC brand S3 ViRGE DX. While this new one fixes the flickering problem of the old one, it's created the new issue I mentioned above. I can't keep buying these cards at $50 a pop hoping to get a good one every time. There's got be be a solution to this off-center image...

Which screen refresh rate and resolution are you attempting to use in Windows? For 640x480 try setting 72 Hz and 75 Hz (or higher) for the rest.

Sometimes, there are separate configurations on the monitor for CRT image positioning depending on the selected screen refresh rate and resolution.

Could it be that it's a really old crt monitor with manual controls that doesn't remember the settings for each configuration?

There should be software bundled with the driver to adjust the centering. You won't have such a util if you're only using Windows own driver. I used a utility with a generic Trident TGUI9940 back in the day with a crappy 15" monitor without digital controls.

My monitor is a CRT from he early 2000s. It doesn't have a way to remember settings, but on the other hand, isn't DOS and windows 95 set to 640X480 the same thing?

It really shouldn't be this complicated. My other ISA video cards work fine.

I'm trying to install the full package of the utils for W965 and it's saying I don't have the right card installed...
