Help with a TV

[BananaKing]

So, i find my self wanting to buy a new TV. its going to mainly for gaming. with all this talk about HDR and 4K. i think if im going to buy a tv, i want it to be future proofed for next gen at the very least. meaning 4k, HDR and most importantly, low input lag when it has both on.
 
i found this tv for a great price.

UHD  TV 49UH617V: UHD  TV| LG Levant
 
Now here are the questions i have.
Does this support HDR, the one that PS4 supports? as i heard some people having problems where their tv turned out to not really support them
If it does support HDR, does it have a low input lag while its on?
i heard when games are upscaled to 4k by the TV the input lag increases, is that true? will that happen with this tv?
 
i know it seems kind of redudant to play 1080p content on a 4k tv. but i want to get a 4k tv so i dont have to go and upgrade next gen. plus, i get the benefit of HDR gaming this gen.

-"Select LG 2016 4K televisions support HDR10, which we call HDR Pro" link
-HDR doesn't usually add lag, but some of the LG TVs seem to.  sauce
-tiny bit.  Will it be noticeable?  Hard to say.

guess ill have to wait for a better deal.

If you care about 4k + inputlag + HDR the only option that do a good job is the Samsung KS8000 right now. My point is most actual 4k in the market have bad inputlag with HDR enabled with few exceptions like the KS8000 family.

Can you hold a bit more??? Because I think better TVs will be showed in 2017 lineup... HDR is a bit early yet and not all supported TVs do a good job with it.

The RTINGS methods have some small but important flaws.

This mode 4k @ 60Hz @ 4:4:4 + HDR is only possible when the TV downgrade the color range to 8bits and that affect how the HDR is supposed to show (HDR10 requires 10bits)... that is an actual HDMI limitation and RTINGS did not say that to readers. The 4k @ 60Hz + HDR mode runs at 4:2:0 to reach the 10bits of color range (they didn't show that too).

In any case HDR indeed add a good amount of inputlag even in LG (B6 being one of the best options from LG)... Samsung seems to be the better one but not the ideal yet.

The best options I guess is wait the tech mature a bit... wait the 2017 models (at least it will made the 2016 get cheaper).

That tv seems to be  made for your market. So I dont  have enough info to give a suggestion. But  Im on the wait train. Next year we should see hdr explode and they'll  be a lot more to choose from.

Yeap... I guess most manufactures are still trying to find the best way to implement HDR... the results are too different across brands/models.

Side note.

I will love if some company do a 1080p HDR capable TV pleaseeeeeee... dreams comes true.

thanks. i will do just that, unless i somehow find a good deal on the Bravia X800D. i read those were good, right?

Yeap I read it is pretty good for gaming but it is average for movies... never saw one to be for I'm just saying what I read in forums... good inputlag in game mode too.

whats 4k 60hz 4:4:4. whats the difference between that and regular 4k 60hz?

It is called chroma subsampling a way to compress the image to use less bandwidth discarding information our eyes can't see (or at least won't make that difference). RGB uses the full chroma subsampling or 4:4:4 while the Y'CbCr can compress the image... eg. the Y'CbCr 4:2:2 requires two-thirds the bandwidth of 4:4:4 (RGB).

Said that the HDMI 2.0 (2.0a) has a peak bandwidth of 18Gbps that indeed limits the RGB (4:4:4) to use 8bits of color or Y'CbCr with 10bits of color but 4:2:2.





About the difference well... let's try.

so when i game, will i use 4k+HDR+60hz 4:4:4

or should i look at just 4k +HDR + 60hz

take into consideration that i want to play 4k and 1080p content with this.

You can't use HDR10 with 4:4:4 via HDMI 2.0... so it will drop to 8bits color or 4:2:0... PS4 Pro drops to 4k Y'CbCr (4:2:0) when your game is HDR ready.
For 1080p it won't make difference because HDMI 2.0 can handle 1080p RGB (4:4:4) with HDR10.
It is most for 4k where the Pro will chance between RGB (4:4:4) for games without HDR and Y'CbCr (4:2:0) for games with HDR.

There are input lag differences between 4:2:0 and 4:4:4 with or without HDR... each TV models is difference for each model... it is really a mess actually because each brand/model implement these things the way they thing it is better.

You need to read your TV specs to see which modes it supports.

Ohhh and why it is becoming a thing right now??? That is why 4k shows more pixels/details... in 1080p it was pretty hard to see chroma subsampling difference and 80% of content was 4:2:0 but now with these big 4k screens well you can see the difference in picture so manufactures started to give 4:4:4 options.

Pro has two modes: 4k RGB (4:4:4) and 4k Y'CbCr (4:2:0) and HDR10 only works with the last one.

4:4:4 is almost required when hooking a pc to it. it helps a lot with text.

DisplayPort can handle 4k 4:4:4 with HDR10 too but there is no monitor for that yet

jesus christ,... i shouldn't need an advanced engineering degree to buy a tv.
