Question about Sony Ht-Sf150

Sorry - I was referring to a monitor...
The soundbar is controlled via bluetooth without any problems.

The HDMI input is located centrally under the stand's attachment - it works perfectly with a Lenovo notebook.
Incidentally, the screen can be controlled in various ways.

If you look at the HDMI section in the specifications (https://www.sony.ch/de...), you should see that no HDMI input was promised. There is only one HDMI output: (Input/Output: 0 / 1 (ARC)). - Input 0 / Output 1.
