Report "After reconnecting my computer to my X20 Naga ii monitor, I receive NO video. I have checked the connections and I have both analog and DVI cables connected to the RIGHT places on both monitor and PC. However, there is no picture. When I access the OSD on the monitor, it says that it's in Video mode. I cannot seem to get it to switch to PC mode. It only gives me the options of AV and S-video for video sources. Can you help? Thanks"
