4 Best Ways to Fix HDMI Port Not Working on Windows

First, you need to press Windows logo key and P key on your keyboard at the same time. A list of display modes will appear.

Display modes in Windows 10.
Display modes in Windows 7.

The difference between each mode is as follows:

PC screen/Computer only — Only using the first monitor. Duplicate — Displaying the same content on both monitors. Extend — Using both monitors to display an extended desktop. Second screen/Projector only — Only using the second monitor.

Here you can try Duplicate, Extend or Second screen/Projector and see if the any of these modes can help project your computer to your monitor or TV via HDMI.
