MacOS 15.2 screen mirroring stuck on when smart tv is used as a monitor.

I should add that I have two monitors attached, a Dell 43" P4317Q as my main screen connected by Mini DP to Thunderbolt and a Dell 27" U2414H as my side screen connected with HDMI. If I turn off screen mirroring then it defaults to the 27" and doesn't display the mirroring icon in the task bar.

Same problem here with my Mac Mini M4 and LG OLED. It just started without warning. I’ve tried everything toggled all of the settings and I can’t get it to indicate that it’s not screen sharing. I’m feeling insecure about it like my computer is possibly sharing my screen with the neighbors TV?

Every time I change inputs, when I go back to the input my Mac mini is on, the input resets back to video mode instead of the PC mode I set it to.

I don't think I have noticed that with my M1 Mini.

I have the same issue. I have 3 displays, one of which is the HDMI connection to a 4k TV. I have to reset the display parameters after every boot up. Something is seriously broken in the .2 update!

I have the same problem with Mac mini M4 and a Samsung S90C

Same problem here I have the M4Pro hooked to a 55" Samsung TV and screen mirroring to itself its my only connection to the Mac M4 Pro MacOs 15.2 update..... 15.1 was fine no problems

I wonder the same thing is it sharing my screen to a neighbors ? ugh

I have the same problem with my m1 max and my phillips c1 monitor since yesterday's update. I can use the display as such but it now seems to be delayed.

Same problem here with Mac Mini M2 and HP Z38c ultrawide monitor

Crazy. Every time I boot up the computer, the OS forgets my monitor setup. Have to redo everything from arrangements to resolutions! I sincerely hope Apple addresses this soon.

This has also worked for me, I was using a smart TV as a monitor for my M4 Mac Mini

it is showing my 65inch LG OLED TV as 72inch.
