Windows 10: Windows 10 HDMI output only works on a few Smart TVs

I have a Dell XPS 15 9570 running the latest version of Windows 10. I've been projecting to a duplicate display monitor for 4 years. A couple months ago, the projection stopped working after a Windows 10 update. At first I thought it was the update and backed out the update, still didn't work. Then I suspected the HDMI circuitry or cable. I switched the cable, still didn't work. Then I tried connecting a Samsung Series 6 TV and it WORKED! I've tried various TVs and monitors over the last month and have found Samsung Series 6 and Series 7 work, but Visio, TLC, and other Samsung TVs don't work.


Anyone have any idea why only certain TVs work with my Windows 10 HDMI output? Any suggestions for a solution so I can go back to my original monitor would be greatly appreciated.

Connecting a windows 10 laptop to a smart tv using a hdmi cable

Hi,

Thanks for posting your query on Microsoft Community.

HDMI cables do support audio signals, but not all HDMI-enabled video cards support audio. If your HDTV has an audio input, you might be able to connect a separate audio cable from your computer's sound card directly to the TV. Otherwise, you'll need to
connect the audio signal to a different output device, such as external computer speakers or your home stereo system. Follow these methods and check if it helps:

Method 1
I suggest you to refer to the suggestions provided by Karthik Vengaloor and Kaplana from the following link and check if it helps.
