Pros: Excellent picture, standard picture settings require a lot of changes. Great viewing angle. Auto up converts USB movie disk, BD disk and sat/cable inputs just fine. I used a color calibration disk in BD player to set up.

Pretty much everything off.
Excellent WIFI and smart functions, no issues. Sometimes take a while to up convert USB/wifi video to 4k. Not to bad.

Cons: Some very minor light bleed noticeable in the middle edges on a pure black screen. Bleed can be muted with darkness setting. Does not support ARC (Audio return control). But does support audio control. Had to hook an optical out cable to my receiver for surround system audio when accessing media server from the TV wifi or USB connection. HDMI through the receiver is controlled by television very nicely.

Other Thoughts: I am going to open a ticket with Samsung on the ARC to see if maybe a software update can correct problem. Weird since it has AC. Just bothersome that I have to change the TV audio source when content is USB or WIFI instead of Audio back feeding through the receiver HDMI out cable.

Pros: Input lag: 27.4 ms. Response Time: 8.7ms. This TV cannot do 1080p @ 120Hz but it can do up to: 4k @ 60Hz @ 4:4:4. Note the only graphics card that has HDMI 2 which is needed to support this is the geforce 900 series.

Cons: No displayport
