How Do I Connect My Laptop To My TV?
There are several ways to connect your laptop to a TV. In most cases, you'll be able to connect one of these three connectors directly to your TV: VGA, DVI or HDMI. Additionally, unless you're using an HDMI connector, you'll need a 3.5mm audio RCA cable with a mini-jack splitter or a mini-jack connector in order to transmit an audio signal. In most cases you'll need one of the following adapter/cable combinations.
