Weird Display problem.. Please assist

The bigger the cable the lower the quality, I had to spend a fortune getting a decent 10m one.

But if you were using the same cable before... I don't think better cards give out 'stronger' signals or anything. Have you moved the cable around since you changed the card? It is possible you've damaged it, or have it running a different route through the room (could be interference from something).

Only one way to check though, use a short cable and see
