[QUOTE=".... is UHD necessary or not?[/QUOTE]
Good question, the answer is Yes!
I was completely happy with the quality I was getting at my laptops HD1080 res., but I needed a newer, faster laptop for editing the UHD video files i was getting off my Q. So I got one with 16gb ram, i7 proc., 1TB drive, it also has a UHD 3840 x 2160p screen ( something a little more up to date). And I was blown away when i saw the same videos on the new computer! If you havent seen your 4k vids on a true UHD screen, you are missing the big picture ( pardon the pun). So yes UHD matters
