Galaxy s25 mirrors screen to monitor

[Andrew23735]

So when I am at work I have a docking station for my work computer that lets me use multiple screens. i use the same charger to charge my phone. However, since i got the galaxy s25, my phone screen shows up on all the monitors. I have been scouring over google and the galaxy Ai assist for the last hour and a half trying to figure out how to turn this off. Is it possible?

Hi! Welcome to the samsung members community!

Do you have dex turned on?

[Andrew23735]

I do not. Never used it, I just got this phone like 2 weeks ago

Settings / connected devices / samsung dex

Dex is not turned on, never used it

[johnz237]

On your work monitors can you turn off auto detect for inputs?

To be sure though- go to settings- and make sure this is turned off *image. As even if dex is turned on it can trigger *i think

Well the thing is that it's just a docking station. It's a little box with multiple ports and does not have a screen. So I don't think it has setting you know

The docking station isnt remotely connected to the monitors? That's another level of doesnt make sense. To be sure- settings- smart view is turned off?

[Andrew23735]

The docking station is plugged into the monitors with HDMI cables. 

Smart view has all settings turned off.

Thanks for the help by the way, I hope I'm explaining things clearly enough

Ah, so that's the issue—if you have both Dex and Smart View turned off, it could be the HDMI just forcing a screen mirror. I'm unsure if that can be changed.

What I'll suggest is using Smart Tutor to see if they can assist:
