How can I tell if a video card is fixed frequency? I have an old CRT that only works with fixed frequency cards. When I plug it into a normal video card there is lines of red going from up to down on the screen.

Just look for an old @ss card that sucks at any 3d and costs a lot


Look up the specs for the monitor and set the video card to a res/refresh/whatever it will support on another monitor, then try using the fixed freq. one

Single frequency cards haven't been produced for a long long time (< 1991). Long before the advent of 3d. I think only the oldest ISA vga cards were fixed frequency. I used to have a CGA card which were fixed frequency but I never had a fixed frequency VGA card. Modern cards could technically be used but most modern cards I've seen don't come with any software to adjust the exact frequencies anymore.

What's this old CRT you have anyway that only works with fixed frequency cards? Are you sure it's even a vga monitor? Monitors are so cheap now that I don't think you should bother with a really old monitor.

Wait a sec, do you have one of those old 20-22 inch workstation fixed frequency monitors?

It's a Mirror C/T-20HA 20" monitor.


So your saying taht I can put a fixed frequency on a modern video card?

I want to use this monitor on a server, so the video card doesn't need to be 3d.

Anyone know what settings this monitor uses?

I made a cable and pluged it into a normal video card, and got different results when I changed the frequency.

almost gauranteed to be 60hz but the resolution is a shot in the dark, hopefully it uses a "standard" rez, and not some bass ackwards sheet.
