- Many Windows 10 users encountered that their PCs won't recognize the TV HDMI.
- It's possible that the problem is with the HDMI cable itself; make sure it's not damaged.

Users tend to connect a TV to their PC, and while this usually works, many have reported that Windows 10 doesn’t recognize their TV.
Normally, PCs are connected to Smart TVs via HDMI cable. And in the event that this issue occurs, it could be that the cable is damaged.
The first step is to double-check your HDMI cable. Your HDMI cable must be in good condition and correctly connected to your Windows laptop and HDMI device.
Test your HDMI cable to see if it is compatible with your system or the TV. It’s also a good idea to double-check the HDMI ports of the PC and the TV. You must ensure that the HDMI ports on your PC and any HDMI devices are in good shape.
Damaged HDMI ports may inflict the error that prevents your HDMI cable from working correctly on the Windows system.
Hence, if none is damaged, then you can go ahead and try some fixes in this guide.
