A month ago I built an Asus system with an on board nVIDIA GeForce 6150 chip, and a DVI and VGA port that is being used by two monitors. The display driver version I'm currently using is 191.07. Here's the issue ... on certain occasions, after Windows 7 boots, the analog monitor's display is fine, but the digital monitor is black with the message "2: Digital Input Cannot Display this Video Mode". I usually have to disconnect and reconnect the VGA monitor in order for the video to display again on the digital monitor. This doesn't happen a lot, but just enough to be a nuisance. At this stage I'm not certain whether this is a hardware or driver issue. I understand that a newer video driver (195.55) has already been released by nVIDIA. However, before installing the new driver, I thought that someone may have some ideas on what may be behind this issue. Thanks.
