A Samsung LCD television can be used as a primary monitor for a PC. This is convenient for people who wish to use their PC to watch movies or do light Internet browsing from the comfort of their couch. Samsungs and most other new LCD TVs have a "PC input," which is actually just a standard VGA input. VGA cables connect your PC to a monitor, so if you already have one, you most likely have the cable.
Connect the VGA cable to your computer's "VGA out" port, usually designated by a blue colour. Connect the 3.5mm cable to the "audio out" port, usually designated by a headphone symbol or by being green.
Connect the other end of the VGA cable to the "PC Input" port on the back of your Samsung TV. It will be labelled as such. Connect the other end of the 3.5mm audio cable to the hole directly underneath the place where the VGA cable is connected.
Turn on the computer and the television. Go to your input options and select "PC." Your computer should now be using the television as a monitor.
Samsungs can be finicky about the type of VGA cable you use. Be sure that yours has all 15 pins, as some cheap cables do not. Have all of your drivers up to date before attempting to connect to your television.
