So what HDMI ports does it have and what HDMI cables must you use?
4:4:4 chroma is very important to me. Especially when playing PC games on HDTV, because PC games tend to have smaller UI elements and smaller text. Without it, everything becomes blurry and looks odd. It's also important for consoles so I just make sure I have 4:4:4 enabled for all the inputs.
So those ports are HDMI 2 point...what?I has 4 HDMI inputs. It accepts 4k @ 60Hz @ 4:4:4 signal only on HDMI ports 2 and 3.
imgur keeps fucking up when I try to upload for some reason, but...
when I set windows scaling to 100 percent, 422 does clearly look worse than 444 on the last two lines, thought not completely unreadable like the examples posted previous, from my couch I can't tell the difference though, mostly because the image takes up about an eighth of my screen. I also can't think of any time I would set windows scaling to 100 percent on a TV when viewed from the couch.
My original question still stands, is this a make or break feature for a TV?

I've seen this said, but it doesn't make sense. The HDMI 2.0 spec has enough bandwidth to do 10-bit 4K60 at 4:4:4. And there are reviews out there of TVs that talk about their use as monitors.
In the end it shouldn't matter all that much, though. 4:4:4 is most necessary on quite thin elements like text. It's thus important for PCs in general, but not most games in specific. Power lines, bits of foliage, and particles may have a bit of extra shimmer with 4:2:0, but only when very tiny (and AA will help). That's why UHD Blu-ray was content to go with 4:2:0.
Here is a question for you guys
my sony 4k tv does 1080p 12 bit and 4K 8 bit. Would you guys recommend I use 1080p 12 bit?
That picture wasn't zoomed in my browser.But you don't have to disable Windows dpi scaling. You only need to not zoom the picture in your browser.
You will find lots of games with fine details or distance objects or little text where 422 will make those things way worse than 444 at your native resolution.
this right here are my exact feelingsYou could have 4k60hz on 10 bit at 4:2:0 (at least that's what you need to take advantage of HDR) and won't notice much. 4:4:4 is more for text. If you're couch gaming you're so far away that won't notice much. At least I don't...
That's strange. I'm using same settings on same gpu and don't get a washed out picture. Must be your display? The defaulting to 59.94 sounds like a vsync thing, but that shouldnt make much difference anyway.GAF in need of help
I have been playing with HDR for SW2 and i get a really washed out screen. I am currently running a 980Ti through a Marantz SR5010 reciever to my LG65ef9500 TV. I have my card running at 4:2:0@12 bit so i can get 4K 60fps w HDR. Is there anything i can do to get the colors to be more vibrant or is there something limiting the data flow in my setup.
For the record i cant 60fps to stay on, it defaults back to 59.94fps.
Am i having a video card issue or is there something w/ my TV.
Does HDR always wash out the colors?
can anyone post an HDR screen of SW2 so i can compare?
Is there any way else that i can check to see if HDR is working propperly on my setup?
Thanks in advance

It doesnt change your gpu settings, but it displays a 422 image. You can get 444 in pc mode though.Wait so game mode brings the settings to 422?
As someone with only a 1080p tv does this matter?

No don't worry about it. Technically yes, but if your current tv doesn't support 444 it doesnt matter.

Edit: it could be your receiver. My receiver supports 4k passthru, but not hdr, I hook my pc gpu into the tv itself, and an hdmi from the mobo to the receiver for audio. Try that.
Edit edit:. You will have to enable dual display to do this, most likely in your mobo bios on bootup. You use the integrated graphics for sound, and it sends a picture to the receiver, but you just select your tv input for the gpu hdmi and select the mobo hdmi on the receiver. Sounds complicated but is pretty simple once youre used to it!
Make sure you select "extend displays" in windows.
Have you tried plugging the pc directly to the tv? Also make sure you enable UHD color or HDMI deep color or whatever it's called in the lg menus.
HDMI deep color is on.
is there any way that i can test if I am seeing the full color range?
Thanks
Can anyone tell me if I can get any HDR benefit from my TV? Samsung 60JU7100 http://www.rtings.com/tv/reviews/samsung/ju7100
I am having a hard time understanding all the HDR stuff...
Any display that does over 100 nits of brightness(the SDR standard) will start to see the benefits of HDR. At >300 nits your samsung will have an ok HDR effect, nothing amazing but it will be quite noticeable.Can anyone tell me if I can get any HDR benefit from my TV?

Normally youd want the backlight at near maximum settings, but since your samsung isnt full array you'll have to balance it out. You want a bright image but not so much that it turns your blacks too grey.
Yeah, I've seen that matrix and I believe it. I just don't understand why it's the case. That same HDMI 2.0 spec sets max bandwidth at 18 Gbps. For 10-bit color in 4:4:4 (i.e. full data for every subpixel), that's 30 bits per pixel. At 60Hz, you need 1800 bits per pixel per second. A 4K frame is 8,294,400 pixels. So 4:4:4 10-bit color at 4K60 should require 14.93 Gbps, right? This leaves 3.07 Gbps headroom in the HDMI 2.0 spec. I couldn't locate data on HDMI bandwidth needs for audio, but I can't imagine 3 Gbps is somehow insufficient, even for many-channel hi-fidelity sound.It's a limitation of the HDMI spec. Look at this screenshot of the HDMI org themselves.

Imo, no. For video games, other factors like input lag, contrast, motion blur, general color accuracy, etc. are far more important make-or-break features in a TV.My original question still stands, is this a make or break feature for a TV?
This.4:4:4 literally does not matter unless you're using it as a monitor.
Majority of the content you'd use on that screen, outside of a PC environment, isn't built for that spec anyway.
How do you even tell? I just got a TV and spec sheets don't even talk about this.
