I’m using an LG 45-inch UltraGear monitor, which has a 5K resolution and is supp?

Yeah, This happened to me too. I had to make sure I was using a high-speed HDMI cable and then select the monitor as the default device in the old Windows sound control panel. Good luck!

Agreed, and also double-check that spatial sound is turned off in Windows—sometimes that setting blocks Atmos from enabling.

Agreed. I had the same problem. For me, it turned out I needed to manually select the monitor as the Atmos device in the Dolby Access app, not just in Windows sound settings. Let me know if that works.

Agreed. Yeah, and make sure you're using a high-speed HDMI cable too—older ones can limit the audio signal.

Same here. Also, have you checked if the Atmos app or your media player is set to output in that format? Good luck!
