Alternatively, if your TV is old and damaged, you should know how to properly dispose of an old TV.

STEP 1 Know Your TV’s Resolution

  1. Start by figuring out your TV’s resolution. If you have a full HDTV, this will be 1920×1080; and if you have a standard HDTV, it will be 1366×768. Once you understand the resolution of your TV, it’s wise to determine what sizes TVs come in for 2023.

STAT: Aspect ratios (16:9, for example) signify the ratio of an image’s height to its width. This ratio means that any image portrayed is 16 units long by 9 units wide. (source)

STEP 2 Connect and Change Settings

  1. Connect your computer to your TV. Linking your devices should be done using an HDMI cable.
  2. Go to your computer’s search bar once your computer screen is mirrored on your TV. Then, hit the menu button and type in “display settings.” Next, click on the search result.
  3. Find the laptop screen resolution drop-down on the settings menu. There should be a handful of the different display modes you can choose from here. If you have a full HDTV, make sure it’s set to the 1920×1080 option. If your TV is not 1920×1080, check your TV resolution on the manual or online and set it to the proper resolution type.
  4. If you’ve put in the correct resolution and the screen still does not fit, you can find additional picture adjustments by going into the “advanced scaling settings.” Here, customize your scaling screen size to what fits best. Proper scaling will usually fall between 100-500%.


Some TVs don’t support the standard viewing aspect ratio of 16:9. If your device doesn’t use a 16:9, a 4:3 ratio will be the second-best option. But you can look at your user manual to find the correct aspect ratio.
