connecting tv and pc problems!!!!!!!

Hooking the TV to the PC would be the ideal way to do it. Some monitors have a built in video switch. If yours does, there will be a switch on the monitor to switch to a second PC. That's more than likely what that port is on your monitor. At any rate, you'd never be able to access any of the video cards features for the secondary display if the primary monitor had a passthrough port (which I've never seen).
