Help with DeX setup

I’ve got an S24 ultra and one day overnight the screen stopped working. The phone seems fine

I connect it to a monitor via HDMI to USB C and I can see Samsung DeX asking me to unlock. Unfortunately I put my phone in airplane mode overnight so I can see on the DeX screen it’s in airplane mode so my bluetooth keyboard can’t connect

I’ve tried a powered USB C hub and a wired keyboard works but I never get a display on the monitor using the HDMI to USB C cable with the hub

Is there a keyboard shortcut that would take the phone out of airplane mode? Or is there a keyboard shortcut to enable Bluetooth?

I’m thinking the USB C hub isn’t good enough to use USB C to HDMI through it which is why I can’t get the display working

I don’t really want to go out and buy a DeX station either in case I have the same issue still

Thanks
