Actually under control panel, you should have an nvidia control panel icon. The 6200’s support dual display and seem to support tv’s though there may be some models from some manufactures that do not. Here is the manual for the control panel.
Once you get the tv and monitor setup, look into the “full screen video mirror” options. I’m not that familiar with nvidia cards but it seems to have similar capabilities to ati’s theater mode. With ati’s theater mode, whatever video is playing will automatically be sent full screen to the tv. It has to be playing on the monitor also, but can be minimized, behind other windows etc. so you can work with your computer. If no video is playing, whatever is on your monitor (desktop, windows etc.) will be shown on the tv. There’s one catch with ati cards at least. Any playing video can take over the tv signal (video playing on a web page, a video preview box on a video conversion or editing program etc. even if it is not the front window and or minimized). I have found that If I leave a player open (even if it isn’t actively playing anything), it will lock the tv onto its video so you can have other video going and still be able to play video.
