How to Connect a Desktop PC to a TV (Wireless, Free, Without Wifi, Without HDMI) [Step by Step] 2022
HDMI is a type of cable that transfers HD video and audio directly from your computer to your TV. Both your TV and your computer must have an HDMI port.
While HDMI is the best option, you can also connect your TV and computer via DVI, VGA, S-Video, or Thunderbolt connections. If you have an Ethernet cable connecting your computer to a modem, you don’t even need Wi-Fi to surf the web on your TV. You’ll also get faster streaming that way. The only downside is that you’ll have to place your laptop close to the TV.
A scan converter is a device that converts the video signal from the computer to the standard TV format. You may need to set up a scan converter to connect your computer and TV if they do not support a compatible combination of AV cable technologies.
