I have a stock 2010 2.8GHz quad core. My intention is for it to do double duty as an HTPC and general use. I have it connected to a VGA monitor via dual link DVI to VGA into a KVM switch. This works fine. I wanted to then add my 37" Vizio TV. That is connected via mini displayport to HDMI and a cat6 HDMI extender. With either one of these connected everything works fine. Because of this I am assuming the adapters, KVM switch and cat6 HDMI extender are not a problem. But when I connect both the TV works for about 30 sec then looses signal and the VGA monitor starts cycling through the desktop and extended desktop at different resolutions. Any ideas how to get the two to work together?
