It seems like just yesterday that Samsung announced that QLED would be replacing SUHD. And while we had a tough time saying good-bye to Samsung's old moniker, QLED promises to be an even better screen technology than SUHD ever was.

It's so confident in QLED that Samsung's 2018 TV line-up offers six series of QLED screens – the Q9FN, the Q8FN, Q8CN, the Q7FN, Q7CN and Q6FN. These series almost directly mirror Samsung's line-up of 2017 TVs.
