Big congrats. I love my Samsung. Two things. First find out how to put on HDR+ and apply to all settings. Best advice I can give you. It's like lifting a veil on colors on all your inputs. Just awesome. Second for about 40.00 buy the Samsung 4K hard drive it has ten 4K movies and about 30 mini documentaries all in 4K video. It's just a simple 1TB hard drive preloaded with 4K movies like Life of PI, Forrest Gump, The Book Thief, The Counselor, the first two Star Trek movies (with Chris Pine), World War Z and others. If you really want to show off what 4K can do. I went this route because I didn't want to spend 250.00 on a 4K player and 30.00 for each 4K movies when 1080p and 4K is almost hard to differentiate for me sitting back 10 feet but I still wanted to show off 4K when I have visitors well worth the 40.00 bucks. I'll post a link in a second and only works with Samsung 4K UHD TV's.
