High definition TVs give consumers access to HD content in the form of Blu-ray discs, broadcast TV and cable TV. You can also use your HDTV as a computer monitor to run your computer. The larger size of an HDTV would be great benefit for a graphic artist, video editor or someone who prefers to have several windows open and visible at the same time.
1. Connect the VGA cable to your computer just as you would if you were using a regular computer monitor.
2. Connect the other end of the VGA cable to the “VGA” or “PC Input” on the back of your HDTV. If your TV has a DVI PC input instead of VGA, then use a DVI cable to connect your computer.
3. Turn on your computer, right-click the desktop and select “Properties.”
4. Go to the “Settings” tab and adjust your computer‘s resolution to one that your TV supports. Refer to your HDTV’s manual for resolutions that are supported. Your HDTV’s native resolution will either be 1280-by-720 or 1920-by-1080, so you should set your computer to one of those.
