Via Computer (PC or Mac)
Most televisions support connecting a computer by using a VGA or HDMI cable (depending on both your television and computer setup). If your computer and television both support HDMI then only an HDMI cable is required and similar with VGA. Note that you can also connect your computer to your TV via HDMI with a Chromecast device. If you are unsure what connections your computer and TV support, check with your computer manufacturer and TV manufacturer to determine compatibility.
