How To Use TV as a Computer Monitor?

Using a TV as a computer monitor is an excellent way to get a large display on a budget.

Modern TVs have high resolutions and large screens that can rival dedicated monitors.

With a few simple connections and settings changes, you can connect your computer to a TV and use it as a display in no time.

How To Use TV as a Computer Monitor?

What You Need

To use a TV as a monitor, you will need:

  • A TV with HDMI ports
  • An HDMI cable
  • A computer with an HDMI port or HDMI adapter

Check the resolution and refresh rate supported by your TV and graphics card. They should match for the best experience.

Connecting Your Computer to the TV

Follow these steps to connect your computer to a TV:

1. Turn Off Both Devices

Start by turning off both your computer and TV. This avoids any signal issues during setup.

2. Connect HDMI Cable

Connect one end of an HDMI cable to the HDMI port on your computer. Connect the other end to one of the HDMI ports on your TV.

3. Turn on the TV

Turn on your TV first and select the correct input source to display from the HDMI port. You may have to consult your TV manual to find the correct input.

4. Turn on Your Computer

Finally, turn on your computer. It should automatically detect and display on the TV screen.

That’s it! With just an HDMI cable, your computer screen is mirrored on the TV.

Adjusting Display Settings

Once connected, you may need to adjust some display settings for the best experience:

  • Resolution – Set your computer’s resolution to match the TV’s native resolution. This is usually 1080p or 4K.
  • Refresh Rate – Match your TV’s refresh rate, typically 60Hz. Higher is better if supported.
  • Overscan – Turn off overscan on your TV if the edges of the screen are cropped.
  • Display Mode – Set your TV picture mode to Game or PC mode to minimize lag.
  • Audio Output – If needed, change your computer’s audio output to HDMI for sound through the TV.

Make these changes in the display and sound settings on your computer. Consult your TV manual as well for any special settings.

Using a Wireless Connection

Instead of an HDMI cable, you can also connect a computer to a TV wirelessly:

  • Wireless HDMI – Use a wireless HDMI kit to transmit video and audio over WiFi to the TV.
  • Screen Mirroring – Use built-in screen mirroring like Chromecast or Miracast if supported by your devices.
  • Remote Desktop – Install remote desktop software like VNC on the TV and control your computer over the network.

Wireless options give you more placement flexibility and avoid running long cables. However, wired HDMI connections are more reliable and have less lag.

Tips for Using a TV as a Monitor

Here are some useful tips when using a TV as your computer display:

  • Sit at an appropriate distance from the TV based on its size. Too close and you may hurt your eyes.
  • Adjust text and icon sizes to make them legible on a large screen.
  • Use TV picture modes like Game or PC that reduce lag and improve text clarity.
  • Turn off motion smoothing effects on the TV to reduce lag.
  • Close unused apps and programs to maximize performance.
  • Use an ergonomic stand or wall mount to position the TV at eye level.
  • Add bias lighting behind the TV to reduce eye strain.

With the right setup, a TV can serve as an excellent secondary monitor or even a full-time display for your desktop or laptop.
