Many thanks. Browsing the web I've read of several people claiming their HDDs work just fine with recent LG models and they're over 2TB.
I currently own a 2015 Samsung smart tv and it is capable to read 3 HDDs at once (5, 4 and 2 TB). Maybe recent smart TVs can't read GPT hard drives while older ones can?
I'm little confused here and I'd really prefer to know in advance what I'm getting, rather than make a purchase and then be forced to return the tv.
