Q: Interference lines on 30-inch display

Hi there,

Since I started using my 30-inch Cinema Display with my new Mac Mini it shows on very dark areas and black some estrange lines, like interference or "visual noise".

That lines are always "moving" like old televisions with signal interference. Some times are less, and some other more.

It has a Mini DisplayPort To Dual-Link DVI Adapter and the graphic card NVIDIA GeForce 9400 working in a resolution of 2560 x 1600 32 bits color.

Can anybody please help me to solve this problem?
Thank you in advance.

Mac Mini 2.53 Ghz Intel Cuore Dio, Mac OS X (10.6.6), 4 GB 1067 MHz DDR3

That's DVI noise. Is the Apple Mini DisplayPort to Dual-link DVI Adapter a recent purchase from Apple? If so, return it for another one. The one you have is defective.
