A:AnswerI am actually looking for this info myself before making a purchase, as I want to featue for my Xbox One X. There are some conflicting info. Below is the review of rtings.com and they added this: Update 10/26/2018: We have received confirmation that the 49" NU8000 does support FreeSync". Some user reviews or other sites mention that 49 inch doesn't support FreeSync, I just don't know who to believe. I did try to see if stores have 49 inch of NU8000 and Q6FN, but couldn't find the one that had an updated firmware...
