Connect your PC directly to your TV in a fast, simple way. You can show what’s on your PC directly unto your TV by turning it into your monitor with a built-in speaker. You’ll need wires or video cables. You also need a smart TV that can read the signal and showcase it onto their AV1/2 or HDMI1/2 port.

Regardless, let’s talk to connect the desktop to the TV. It’s something people have been doing since the CRT days of TV and the VGA days of PCs.

How to Connect Desktop to TV

Modern TVs mostly use HDMI in order to connect with modern PCs. Otherwise you’ll need a VGA to HDMI adapter in order to establish a connection between the VGA port of a PC and the HDMI port of an HDTV.

Therefore, you’ll need the following to connect your desktop PC to TV.

  • An HDMI cable.
  • Adapters as required by your PC.
  • An optical cable connection if there’s no ARC.

Just connect the HDMI cable to your PC then switch to “HDMI1” or “HDMI2” on your HDTV to see a mirrored or duplicated version of your PC screen on the TV screen.

Make sure your desktop or laptop PC is close enough to the HDTV for the HDMI cable to reach between both of them.

Determine the Connection Type for Your PC

HDMI is usually the de facto video and audio connection format for modern HDTVs and HD PCs. You can also use a variety of other connection types used by PCs and laptops today. Many are compatible with a simple cable or adapter. Others require outright converters though.

Otherwise, you might instead have to use Chromecast, the Google Home App, and Google Chrome to screencast or mirror your PC screen onto your TV screen wirelessly.

The High-Definition Media Interface or HDMI Standard

This simple cable and port standard can be used to display your PC on your TV, among other media player connections. However, some device makers use a different size and version of HDMI port. It was also developed back in 2002.

This means that even though they’re compatible to most cables, you need a special cable to enable, for example, HDMI-eARC or HDCP or any other new feature on new HDMI specifications.

HDMI Connector Types

You have three main HDMI connector types. They’re purely based on the device size. Like how USB-A and USB-B ports work with PC-sized or peripheral-sized devices while USB-C, Mini-USB, and Micro-USB connectors are for anything the size of mobile devices.

  • Standard: The most common connector type. It’s the one found on the back of modern HDTVs as well as PCs and laptops. They’re about ½ of an inch in width. They’re also known as the HDMI-A or HDMI Type A connection.
  • Mini: The HDMI-C connector type is intended for portable devices such as smartphones, tablets, and smaller laptops. You’ll need a special cable adapter to connect a mini-HDMI laptop to a standard-sized HDMI-A port, but usually they come with such a cable.
  • Micro: The HDMI-D connector is for even smaller portable devices such as camcorders and digital cameras. This connector type is also found among single-board computers and even thinner laptops. They need a special adapter or cable to fit into HDMI-A ports.

The DisplayPort or DP Standard

DisplayPort or DP is used in some TVs. It’s a later format than HDMI (designed in 2006) but it’s not as widely adapted. However, it’s easily adaptable to HDMI. You can buy its simple cables online as well as brick-and-mortar computer peripheral stores.

You can also avail of VGA to DP or HDMI to DP adapters for this specific format that also combines audio and video together in one cable. DisplayPort 1.4 is superior to HDMI 2.0 in many ways, but HDMI 2.1 and above are all catching up.

The Digital Visual Interface or DVI Standard

Digital Visual Interface (DVI) was supposed to be the successor to VGA and AV but HDMI and DP came around and usurped this intention. It was the first format to stream uncompressed HD video, but like VGA it only streamed video and doesn’t combine audio in one wire or connection standard.

DVI is one of the first digital formats for PCs to use for monitors, hence its video-only wiring. You’ll rarely see it used for laptops but it’s prevalent among desktops. You can easily get a DVI to HDMI adapter or converter but you need a separate audio cable for the sound.

The Chromecast Standard

The Chromecast device connects to your HDTV via HDMI and powered by a USB power adapter. It could be setup by the Google Home App on your mobile phone. You can then use it on your Google Chrome web browser by clicking the “Cast” button available once the device has been setup.

Just launch Google Chrome then go to “More” or the Three Vertical Dots then press “Cast”. From there, choose between casting a tab, the desktop screen, or a file (like a video).

The Video Graphics Array or VGA Standard

This is a PC to monitor standard from 1987 that persists to this day but is giving way to the two-in-one audio-video connection afforded by the HDMI standard. The Video Graphics Array connector is a multi-pin one that sometimes requires screws on the side to keep it plugged in.

It’s also analog and requires a special converter box (and separate audio cables for the sound) in order to convert the VGA video feed into HDMI for your HDTV.

Other Audio-Visual Video Standards

Old Cathode-Ray Tube TVs use either RCA composite—1 yellow video cable, and 2 stereo sound cables (red and white)—or RCA component video cables—3 video cables (red, green, and blue) and 2 stereo sound cables (red and white). Some use S-video or SCART instead.

Thunderbolt 2 and 3 are for Apple Mac PCs. The Thunderbolt 2/3 port requires a dongle or adapter to use with an HDMI cable. Apple also has Lightning ports but they’re reserved for mobile devices like USB-C.
