I recently purchased and set up the NEC Multisync 20WMGX2. It is a great looking monitor. However, when I look closely at the screen, there appears to be streaks of light going across it - almost like the appearance of snow or rain. I am only using the monitor with my PC. I have triple checked all the connections (DVI signal cable) and the problem persists. I have not touched any of the monitor settings and it is set to standard/initial factory settings. There is no TV or cable hookup, and I am unable to find any reference to this issue in troubleshooting part of the owner's manual. I am hoping that this problem is related to my lack of experience with LCDs. If it helps my os is vista and my video card is an nvidia geforce 6150 se. Any assistance is greatly appreciated. Thanks, Steve
