MBPro acting strange when connected to a tv

[zoran]

Im connecting a 16" M1 MBP to a TV using an HDMI cable, but on the TV i can only see the opened windows scattered all around. I cant get out of this mode, cant see each window/app separately, cant operate the mbp normally... and everything on my mbp display is so much smaller... dont look normal to me.

How does your MBPRO react when you connect it to your tv via the HDMI?

I have no idea what this means, can you show us a photo?

When I connect an external display I always switch from mirroring to extended desktop.

Hmm... i have 3 HDMI ports on my TV. One of them is called eARC/ARC the other two have no special inscription. On the eARC port i noticed that it works fine, whereas on the 2 plain HDMI ports the problem occurs... all ok now.
