My wife is fond of saying my an Alpha Geek... I correct her that no I'm a Retired Geek, I started messing with TVs over 60 years ago and started programing computers 50 years ago.
I see people asking if you can plug your phone/tablet/game into the TV on board ships.
I wondered myself, which is why I took along an HDMI cable and adapter.....
When we got into our cabin on the Nieuw Amsterdam I was tickled to see the TV was a Samsung of the same series (different model) as our home smart-TV.
When I turned the TV on it immediately started playing the Muster drill and safety video.
I also noted that the remote is a simplified remote with limited functions.
When we got back from our muster drill I took out my mini-flashlight to see what I could see, and saw the TV only had a cable in the Ethernet Port, there was the 2 @ HDMI ports and a USB-A port, just as I expected.
I took out my Samsung phone to see if the phone would detect the TV via Samsung's Smart Thing function, or via WiFi, or via Bluetooth. Only Bluetooth was detected, in fact I detected 6 different Samsung TVs!
When I turned the TV on it started playing the Muster drill video, again. In fact if I turned the TV on after it had been "off" form some time it always started the Muster Drill (this is the important part)
Because the TV did not stay at whatever I had left it on (eg like the Bow Cam), which is what my home Samsung Smart-TV does, I concluded that this TV is not running the standard Samsung software, but is instead running some custom package, where the TV "signals" the ships servers to start showing the Muster drill when the TV is turned on.
Now without a different remote I could not tell if HAL's software has the other inputs turned off or not, but I'm going to GUESS the answer is off.
Now this may only apply to the Nieuw Amsterdam in the fall of 2023... but it may apply to much of the fleet also
