Thanx for replying . . .
My onboard graphics supports VGA, DVI, HDMI and DisplayPort. My new monitor also has all of those connections. I have only been able to get a signal displayed on my monitor through the VGA input and, after hours of frustration, the HDMI input. BUT, when I choose the HDMI input my mouse and keyboard input is ignored. So all I have is a lovely Windows 7 logo page. When I use the monitor OSD to choose the DVI or DisplayPort input all I get is a brief popup saying "no input found". Any ideas or suggestions are very welcome.
