no 4 k option when sending through sound bar.
I recently bought the 2022 Apple tv 4K. I noticed when I connect the apple tv directly to my tv I can select the 4k picture quality. But as my tv does not have an HDMI out, I need to send the apple HDMI cable to the sound bar first then into the tv. When I connect this way the apple tv no longer gives me the option to select 4K, the highest 1080p.
What am I doing wrong, both HDMI cables are 2.0 or 2.1, all 3 devices are ARC.
I could use the optical from the tv back to the sound bar but then, I will need to make use of the sound bar remote. I quite like that the apple remote controls everything.
Is there another way to send 4k picture quality via the sound bar?
