I just got my new MacBook Pro 2.4ghz with 256mb nvidia card. I also upgraded RAM to 4gb ::drools:: I also picked up a 30" cinema display hd at the same time. I've gotta say... I was absolutely in love... until I noticed that the darker (mostly black) portions of the screen would random flicker with static lines. I thought that maybe it could be static from my speakers, so I unplugged them and move them away. Still the problem was there. I changed outlets and everything. I even plugged the cinema display into an entire separate outlet from the Macbook pro. Same issue... So I returned the cinema display and bought a new one... And guess what... SAME problem! This weekend I'll try plugging in a different LCD to my macbook pro to see if it's something wrong with the notebook. I think I've fully eliminated electrical interference since I've turned and unplugged every device except the laptop & monitor and it still happens. Thanks in advance for any help that anyone can provide. TechTool Deluxe tests passed for everything including vram.
