Trying to use old (dvi out) gpu with new Asus monitor =no signal

[DarkSideA8]

Pulled out an old ATI gpu to try to connect to a new Asus monitor. Long story as to why - but to cut to the chase... We get no signal.

Bought a new dvi to hdmi converter cable and we got no signal in either hdmi inputs.

Card seems to be working (fan on the gpu spins) and all connections are solid

Ideas? Is the presumption that the gpu is dead - or is there another possibility? (don't have another gpu to try, atm)

Huh. There was a response here a moment ago...

We used a cable like this https://www.bestbuy.com/site/insignia-6-dvi-d-to-hdmi-cable-black/6187119.p?skuId=6187119

Is there any reason that this might be the problem?

Edit - I found the old ATI converter dongle. I hope to try it out tomorrow. There's some indication on old forum posts from yesteryear that it is required 'magic' to get the card to talk to the monitor.
