Help Needed witjh Older Graphics cards

[KWJay]

Hi Guys.

My mate recently bought himself a shiny new lg 19" widescreen monitor to run hos 360 and pc on. His 360 is plugged into the VGA port and we've bought a basic AGP graphics card (TNT2 Chipset) which has a dvi port on it so he can plug his pc into the screen (did have integrated graphics with VGA only).

The trouble is, windows finds the card on bootup, will re-boot and reload fine, but when i change the resolution the card stops out putting a signal! Now i thought it was just the card, so we got another to try again, This was a geforce4 Ti4200. Same thing happened.

I then changed the mobo and have re-installed windows but exactly the same thing is happening! Windows finds card then no signal when resolution changed. With the 2nd card in the pc won't even POST now!! I'm completely baffled by the whole thing!

Anyone got any advice? we don't want to spend any more money if possible! lol!

when you change resolution im guessing the card is running at a refresh rate that the tft can;t support. can fix this in 2 ways, set and apply cuztom rez in drivers, so that screen rez and refresh rate are applied together.

or, hook up to a crt, change the rez to whatever your gonna run on the tft and see what refresh rate is applied, then change refresh rate to 60hz, then plug it into tft.

happened to me recently, setting up server with a radeon 7200 card in it. when windows booted up it rez was out of range. turns out that it was refresh rate of 87hz being applied as standard.
hooked up to crt and found that out then changed it, installed correct drivers, shut down and connected back to tft. job done.

its always good to have a crt lying around. i still use a crt as my main screen.

Thats a good idea MAv, any idea how i'd add a custom res to the drivers?
