Im looking to do a tv upgrade and I want to use it both for watching TV and console gaming but PC gaming as well.
Ive narrowed my choices down to a samsung J series (for its 3d and HDR), K series (for its quantum dot display and wider color gamut) and the LG OLED screens (perfect contrast levels and 3d)
They all have fairly similar input lag, and 4-4-4 4k 60hz
I was wondering if anyone on here has had experience with these screens for gaming
Also curious about anyones experience with curved screens as well as using passive 3d for pc games

My system specs
CPU- 2500k @4.8
GPU 980 ti hybrid currently at stock
16gbs 1866

Check the refresh rate of the TV at 4K resolution that is very Important thing.
if the refresh rate the < 60, then display will give you so much of lag

and to play games at 4K you will get less frames because 980Ti is not fully 4K gaming card

980 ti can run a lot of games in 4k from a lot of benches Ive seen, especially with an OC which I will probably do as well
The screens mentioned all have 120hz native but I think they only accept 4k 60hz input and no 1080 120 hz
the input lag for all of them is around 20-30 ms.
The LG can do 4-4-4 4k but not 4-4-4 4k HDR
The Samsung can do both but no 3d of course

if 4K refresh rate is 60hz, then regardless to the GPU power you cannot see more than 60 FPS with any game
and
input lag is more, so, I think you cannot play games well with these monitors
and
your cpu is weak for 980 Ti, CPU could become bottleneck with 980 TI, I think you cannot utilize 980 Ti's full potential

Bottlenecks only happen asset lower resolutions, at 4k I'll be pushing the gpu so hard the it won't be waiting on the cpu to finish computations. What I'm interested in is in actual experiences with these screens. The response time for the screens is like 1 or .1 ms. The ks8500 has 23ms input lag while the c6 is like 32ms

Most of the 4K videos will be in compressed form and while decompressing for rendering it will be much much load to the CPU, so good CPU is required with 4K

If a ps4 can decompress 4k streaming I'm pretty sure a 2500k desktop cpu that's been overclocked can handle it. My phone can decode 1440p just fine not to mention.

You cannot compare with your phone's CPU, it is RISC cpu, while desktop is RISC, you can check the cpu utilization while rendering 4K

A third gen i3 can do 4k60 with 5% cpu use so I'm pretty sure a second gen i5 can do it too. What i need is info on the screens, not my system.

Are you using external GPU, if so, your GPU could be workhorse, Can you try to same play 4K content from iGPU with the same CPU and check how much cpu utilization is reaching?

Don't check from youtube, that is not the right test.4k we will call 2160p, so download and check any 2160p
(some videos will be labelled as 2160p but they run 1440p in actual, so you need to check properly). You need to check 4K loss less samples.
Download something from this website, or download this video from the link below and check how much cpu is utilizing while playing this video

Just did a 4k test, MPHC ran just fine with 4k downloaded content, never went over 60 % with the unreal engine doing a light build. V-lan took up to 100% if I skipped ever, but would be around 60% if I leave it alone. Gaming at 4k was great, got 45-65 fps with shadows of mordor with all of the settings maxed and everything else was hitting 60fps consistently.
