How To Fix A Zoomed-In Computer Of A TV Screen

Several issues can cause your computer to be zoomed in on your TV, making finding the problem challenging for most people. First, when facing this problem, you should ensure your computer and TV have no outstanding updates that haven’t been installed.

You can also try to decrease the sharpness of the TV to less than 10 and see if this resolves the issue. You can try to relabel the HDMI connection on your TV that your computer is plugged into to your PC and see if this solved the problem. 

Step 3: Check The TV’s Resolution 

The next step with your TV screen is to check the TV’s resolution settings. You will need to open the menu, go to settings, and then go to advanced settings or advanced screen resolutions settings. 

Open the resolution options and ensure the TV is set to 1920 x 1080, which is the perfect resolution for most computers. Go back and see if the issue is fixed. 

Step 4: Change Your Computers Resolution

From there, click on the PC and devices selection and go to the display settings. On this page, you should see a slider for the resolution of the computer. Set this resolution to 1920 x 1080 and see if this has solved the problem.
