The odd thing is that I get BLUE horizontal scan lines now whereas I got only green and red ones with the stock cable.
Is it because the cable is too long?
Im using LCD reduced (CRU) with a 7950.
I have three 3 foot cables and three 6 foot cables. Overall the shorter 3 foot cables do better. Also try using a different port of your 7950. My cards have two ports on each and the bottom card's second port got me the furthest overclock so it does matter. You might also try manually setting the total pixels down until they are as low as possible then up the refresh like i posted in my other post.
The difference in scan line's color is likely the difference in each DVI connection lane. You no longer get that color line because that lane of color is now stable or stabler(LOL).
