My son plays with a PS3 and a PS4; he says that there is a noticeable difference when using game mode. Maybe as much as a 1/2 second difference. Just his thoughts, not measured at all.
The PS4 must be turned on to be recognized before game mode can be selected. The PS4 is in HDMI 2.
We received the 48 inch version of the TV yesterday. So too early for a considered evaluation.
But, initial thoughts are very positive. I have scoured this forum for a couple of weeks. I had never heard of all the things that can go wrong with an LED screen. Clouding, flashlighting, light bleed, banding, oh my!!!! From what I have seen so far and after looking for it with a black screen at night and dark scenes at night, I have panel TS01 and I have not seen any such issues yet.
I went from my CRT Sony Trinitron Wega 1080i 36 inch. I loved that tv. But, after 8 years it died. I planned to get a Sony as I have only had a Sony for over thirty years. My husband is still watching and enjoying a 2003 Sony XBR LCD! But, after much research reading reviews and this forum, I decided on this Samsung H8000. It made the list of 10 best televisions in the world as did a couple of Sony televisions.
Right out of the box, the picture is crisp, no motion issues, colors are great, skin tones look natural, and the black levels are very dark with no light bleed at all. Right out of the box in standard picture mode, it is almost perfect for me. We tweaked the settings very slightly in standard mode. I put sound on clear voice mode.
The only trouble I am having at all is voice recognition when trying to use voice interaction.
I was actually sad to not get a Sony, seriously almost 1/2 my life with a Sony tv!!! But, this tv is amazing to me and is far superior in picture quality to my 2006 CRT. And, to the 2003 Sony XBR, granted that Sony is an older tv.
