How to Connect Your Computer to Your TV: Step-by-Step Guide

Have you ever wondered If you could watch your flickr photos and youtube videos on your TV screen through you PC, if yes then this is the right place for you to find out how to connect your PC or laptop to your TV, so that you could do whole lot of things other than watching videos, your word documents, excel spreadsheets on you TV screen.

It is very easy to set up the connection between your PC to your TV and can be done very cheaply, and in some cases free. The cost only comes in with cables and adapters which are cheap. It should be possible for everyone to achieve for well under $100. This post will cover the procedures of connecting your computer to your television. We will cover lots of different scenarios so I hope by the end of this article, you’ll able to achieve this goal.

WHAT YOU NEED

  • A Computer, desktops and laptops will both work. You will require a spare output from your video card (in some PC there are build-in outputs). Modern laptops often use USB-C (DisplayPort Alt Mode or Thunderbolt) or HDMI.
  • A Television with some type of AUX input. For best results, look for HDMI ports that support 4K/60 Hz and HDR.
  • A Stereo with some type of AUX input (optional if your TV speakers are fine). HDMI carries audio; otherwise you can use a 3.5mm-to-RCA lead or optical out if available.

AUX stands for Auxiliary, which means an input from an external source. Most televisions have these as they are what you would use to connect your DVD to it.

CHECK WHAT IS THE INPUT TYPE OF YOUR TV

  1. HDMI: High Definition Multimedia Interface: The simplest, best-quality option on most TVs and laptops today. One HDMI cable carries both video and audio, supports 1080p and 4K (and higher on newer ports/cables). Use High Speed/Ultra High Speed HDMI cables for 4K/60 and HDR, and make sure your TV input supports 4K/60 and HDCP 2.2 for streaming apps.
  1. DisplayPort / USB-C (DP Alt Mode/Thunderbolt): Common on PCs and newer laptops via USB-C. Many USB-C ports can output video using DisplayPort Alt Mode; some require a USB-C→HDMI or USB-C→DisplayPort adapter. Not all USB-C ports support video—check your device specs. Learn more about USB-C DP Alt Mode.
  1. DVI: Digital Visual Interface: Older but still seen on desktop GPUs. Works with adapters to HDMI (video only—add a separate audio cable).
  1. VGA/XGA: Video Graphics Array: Very old analog connection. Image can be soft and often limited in resolution on TVs. Use only if nothing else is available (you’ll also need a separate audio cable).
  1. S-Video / RCA (Composite): Legacy options only. Fine for old gear, but poor quality for text and modern content. Prefer HDMI or USB-C where possible.

How to decide which connection to use?

  • If computer has HDMI and TV has HDMI – Use HDMI (video + audio).
  • If computer has USB-C (DP Alt Mode/Thunderbolt) and TV has HDMI – Use a USB-C→HDMI adapter/cable (look for 4K/60 & HDCP 2.2).
  • If computer has DisplayPort and TV has HDMI – Use a DP→HDMI adapter. For 4K/60, choose an active adapter that supports HDMI 2.0/HDCP 2.2.
  • If computer has DVI and TV has HDMI – Use a DVI→HDMI adapter (video only) + separate audio.
  • If both sides have VGA – Use VGA (last resort) + separate audio.
  • Legacy mixes (S-Video/RCA) – Use matching adapters; expect low picture quality.

How To Configure Your Video Drivers:

  • Windows 11/10: Connect the cable, power on TV, select the HDMI input. Press Win+P to choose Duplicate, Extend, or Second screen only. Or go to Settings > System > Display to set resolution/refresh rate and identify displays. For wireless displays (Miracast), install the “Wireless Display” optional feature and use Settings > System > Display > Connect to a wireless display.
  • macOS (Ventura/Sonoma+): Go to Apple menu > System Settings > Displays to arrange screens, set resolution/refresh rate, and enable HDR if supported. For audio over HDMI, open System Settings > Sound > Output and choose your TV/receiver.
  • Laptops: Many models also support a quick monitor toggle via Fn + a function key with a screen icon.

Wireless Options (when you can’t run a cable): On Windows, use Project > Connect to a wireless display (Miracast). On Macs/iPhones, use AirPlay to a TV with AirPlay-2 support or Apple TV. From any desktop browser, you can cast a Chrome tab or your desktop to a Chromecast/Google TV.

Configure Your Vista Or Xp: These legacy steps are no longer required for modern systems. Use the Windows 11/10 or macOS instructions above for current devices.

After these steps you’ll surely be having videos both on your computer and your TV set. Now its the time for audio configuration.

How To Configure Your Audio:

  • HDMI to TV/AVR: Audio is included. If you don’t hear sound, select your TV/receiver in Windows Sound > Output or macOS Sound > Output.
  • USB-C/DP→HDMI adapters: Most pass audio; pick one that lists HDMI 2.0/HDCP 2.2 if you need 4K/60 & streaming app compatibility.
  • Analog setups: Use a 3.5mm stereo plug to RCA pair cable between the PC’s headphone out and the stereo/TV’s AUX in.

This procedure can also be applied when connecting PC to a Projector.

Quick Tips & FAQs

4K at 60 Hz & HDR:

Use HDMI 2.0 (or newer) on both ends and a certified High Speed/Ultra High Speed HDMI cable. For DP/USB-C sources, choose an active DP→HDMI 2.0/2.1 adapter that supports HDCP 2.2.

USB-C port not outputting video?

Not all USB-C ports support video. Check your laptop’s specs for “DisplayPort Alt Mode” or Thunderbolt.

Overscan / edges cut off:

Set the TV’s input to “PC” mode if available, disable overscan on the TV, or use the scaling/underscan slider in Windows/macOS display settings.

No sound over HDMI:

Pick the TV/receiver as the output device in system sound settings. Some DVI/older adapters carry video only—use a separate audio cable.

Approx. costs (typical street prices):

HDMI cable ($8–$20), USB-C→HDMI 4K/60 adapter ($15–$40), DP→HDMI 4K/60 active adapter ($20–$45), long certified Ultra High Speed HDMI 2.1 cable for gaming ($20–$40), Chromecast/Google TV or Apple TV for wireless casting ($29–$149).

Casting from Chrome:

Open Chrome → menu → Cast → choose Cast tab or Cast screen.

Now it’s all done, we hope that you wont find any difficulties connecting, but if you are, do leave your queries in comments.

What’s New in This Update

  • Added modern ports: USB-C (DP Alt Mode/Thunderbolt) and DisplayPort with adapter guidance (active vs passive) and HDCP/HDR notes.
  • Replaced legacy OS steps with current Windows 11/10 and macOS display/audio instructions, including Miracast and AirPlay links.
  • Included wireless casting (Chromecast/Google TV) and quick Chrome casting steps.
  • Expanded 4K/60 & HDR requirements and troubleshooting (overscan, “no sound over HDMI,” USB-C video support).
  • Added current price ranges for common cables/adapters to help readers budget under $100.

  1. It is not possible to accomplish connecting both video and audio from your computer to your TV without either a PC input on your TV or an audio/video signal combiner. The special device required for this is costly. I found a cheap one once on Amazon but it quit working after a few months and they are now, no longer available.

    I have a set of computer speakers remoted to underneath my TV with simple connections from my computer. A cheap audio signal splitter will allow you to have sound at both your TV and your computer with two sets of computer speakers. They are usually on the shelf at Walmart. The audio on the cheap computer units while not as good as a quality sound bar is quite reasonable. The video is of course simplicity itself. Use an HDMI signal splitter with signal booster to connect both your TV and your PC monitor and set your TV’s or TV and monitor, for the appropriate HDMI connection. I use a 50 inch set for my TV and a 43 inch TV for my monitor. The two splitters and booster are quite reasonable. The cables about the same cost as the HDMI splitter/booster.

  14. how do i find video card to change settings on computer to transfer over to TV? when i follow these steps, once i go into advanced, how do i find the tab that corresponds with the video card? i can’t find this. any help?? Thx

    Go into your “Control Panel” and load up your “Display” propertiesClick the “Settings” tab and you will probably still see one monitor depending on what type of connection you used.Click “Advanced” and then select the tab that corresponds to your “Video Card” in my case it was Geforce 6600 GT.
    Here you have all the options for your card. If you are using a Nvidia card, click on n-View Display Settings, otherwise, whichever option shows you multiple display types.

However, if I switch HDMI inputs on my TV to use my cable box or Xbox and then try to go back to my computer input, the screen just goes black; and it stays that way until I disconnect and reconnect the HDMI cable from the back of the TV. I have to do this every single time I switch back to my PC’s HDMI input in order for it to work. Is there any way around this??

A few hours later the screen on the TV started going funny and now my TV doesn’t work with my HDMI connected to my computer or PS3. The TV a Sharp 42″ Aquios still works for cable and the computer a Dell laptop still works. Is it my HDMI cable that went bad or something more? Any help would be greatly appreciated.
