I have it connected via DVI and I have installed the driver that it was inside the CD. Many times suddently it loses the signal from the PC and it appears 3 different weird pictures (with many colors) and even I here things (the media player playing music) it doesn't appears again the signal from the PC and I have to restart the system so it can see the signal from my system. I have tried with different dispaly and I didn't have problems so the system its ok. Any idea?
