Subtle waves on screen... from my new Arcade VGA or my computer?

[ebo0763]

I just hooked up my new Arcade VGA on my PC. Everything is fine except there are waves (sometimes horizontal or diagonal) going across the sreen. It doesn't distort the image, it's more like white (or bright) and pretty fast and chaotic. It's not there all the time, it depends on the image of the game. In fact, most of of the time when you can see it, it's pretty subtle, but it's still there and I know it's not supposed to be there. It's especialy noticable on a blue surface. For instance, at the title screen of TMNT 1, it's at its wost.

I tried two monitors, the WG k7000 and the WG k7400, same thing for both. Andy at Ultimarc didn't think it would be the card itself but rather an interference. I removed the possibility of an magnetic interference from the electrical tranformer box by moving further in another room. I even tried in another house to see if there was something wrong with my house wiring. Same thing.

I'm running out of ideas. Could it be the computer? Mine is a Dell Optiplex GX280 and I'm very happy about it. I hope I wont have to change it... what do you think?

What resolution are you running?

It's a 15 kHz monitor.

Try a different vga cable from card to monitor?

[Nephasth]

No, what is your resolution set at on your computer?

Ok well, thanks guys but I've found the problem. There was teeny weeny little short in my cable wiring.
