Dual monitor: how to change the refresh rate?
Hi,
I want to connect a second monitor to my tablet PC. I succeeded once when I connected an analogue monitor (Samsung 1600x1200@85Hz). Now I want to connect a digital monitor (Samsung 1920x1200@60Hz) and I am having serious problems.
Typically both screens go black when I connect the VGA cable. The PC has dvi output but I can't find a cable since the connector on the tablet side is non standard.
I believe the root of the problem is that the monitor refresh rate is set to 85Hz in Windows7 and Windows7 does not allow me to set it to 60Hz.
My question is how I can change the refresh rate of the monitor?
