do you have the driver installed for it? that card is 7 year older than windows 95

That is a vanilla VGA card, it cannot do 256 colors in 640x480.

^This. That's a positively ancient card, not at all suited for PCs that can run (or even crawl) Windows 95. Windows 1.0, maybe...

Same here. Never got it to work in 640x480@256.
It had got a mode utility, though, to switch to CGA, EGA and Hercules emulation modes (works).
Plus, it supports 800x600@16 - according to the chip's datasheet.
- Again, never got that to work, either.

Had no idea it was that old, I suppose I have to look for a newer card that will work on Windows 95 with the 256 color option

Yes. Video memory is key here.

256 colours require 8 bits per pixel. To support 640x480@8b you need 640x480x8=~2.4Mb=300kB, but as you only get to choose between 256kB and 512kB, you need at least 512kB to support 8b colour at that resolution.

Tbh, I'd recommend going for at least 1MB so you can do 800x600@16b colour (65k colours), or more if you can find it. WIth 2MB you can do 1024x768 or 1152x864@16b (or 800x600@24b, but the added value of true colour is generally far less than the advantage of a higher resolution)

That's right. With 256KiB, 640x400 is about the maximum resolution (in 256c).
Unfortunately, this mode isn't supported by Windows 95. Some DOS games with VESA supported it, though (Höhlenwelt Saga ?).
If memory serves, some vendor drivers for Windows 2.x and Windows 3.x exited once.
(Paradise provided such a 640x400@256 driver for Windows 2.03, maybe Windows/386, too.)
