Fuck my prior preparation day with the Chromecast with Google TV before the hotel checking…
I don’t travel too often so my Chromecast needed some tweaking (AKA updating system and apps etc), I like to take it as a travel companion and found out this shitty frame around the TV.
It is the first time it happened to me, I can see this being annoying for frequent travelers.
Probably not custom. Many brands allow the tv to be put into hotel mode. If you have your own remote (or an IR blaster) then you can take them out of it.
The software was labeled with their brand.
