I switched HDMI1 to: Picture Mode Settings > Expert Control > Color Gamut > Wide

The resulting measurements were based on DCI-P3 so I calibrated appropriately. Luminance of all primary and secondary colors had to be boosted substantially. Playing 1080P reference material gave very good results.

If we were getting DCI-P3 content I'd be happy, but the UHD Blu-Rays should be in a Rec.2020 container, not DCI. The EF has no where near enough control ability to move the colors to coincide with the D65 to max saturation 2020 line (except for Blue).

2016-2018 will be interesting as the new models come closer to true 2020 ability.
That is pretty much how my Gamut looks when doing a DCI-P3.

In the service menu you could try turning off Dimming, that will give you a nice boost in Nits. Probably what takes place when a UHD disc is flagged.

Yes. Color Gamut Wide does little more than extend 709 outward and does little to redirect colors to 2020. Fingers crossed for future models.

The EF9500 is a 10 bit panel. I went into SM using the SM remote. It said 10 bit.
That's what i thought, though , I've seen some thread claiming that EF9500 simply can't receive 2160p 10bit due to HDMI EDID connection issue. I think it is irrelevant whether it is true 10 bit panel or not.

Yep. Thanks you very much posting your findings as well. Looks to be the same results I had and was discussing while you were away from your set. So it makes sense that something like the bright red flare in the UHD HDR version of Mad Max would show up Orange instead of red on these TV's? Same with The Martian landscape (in the Martian) appearing more orange toned than it should?

It's a bit wonky and probably not the best for accuracy, but I've been able to push the colors toward rec2020 until the input pattern gets above 90% saturation. Except magenta...that doesn't take well at all to swinging toward the rec2020 space.

You say you hope that it is fixed on the next gen panel...but that does not help us now! :eek: I am hopeful either via firmware or CMS adjustments we may at least get the current sets to a place of more acceptable gamut mapping for rec2020. If not, at least I've been blown away by even 1080p content since calibration. Maybe I'll go for 3D versions of films vs HDR if this ends up being the case. Or looking closely if the Panasonic UHD Player offers the ability to turn off HDR (and hopefully also forcing the rec2020 gamut back to rec709).

@sillysally , does the use of a 3D lut offer you a better ability to actually map the display for rec2020? IIRC it seems like you've suggested it does. Although we'd need a processor that can accept HDR for it to be truly viable for UHD Blu Ray. Not to mention the $$$

I never meant to suggest in my post that The EF 9500 is not a 10 bit panel nor did Robert ever suggest otherwise. The Downconversion I was referring to was in regard to dolby vision and I should've been clear in my original post. I miss read the original posters question about the HD or signal he was referring to. I did not realize he was referring to the non DV HDR signals.
so, as I understand, apart from DV, there is no problem receiving 2160p 10bit signal??

But as I'm still confused if what you're saying is only related to dolby vision downscale to standard HDR? or does it affect color bit??

Makes one wonder if using WCG on a tv that does not reproduce it very well is worth switching to when watching HDR.

Does anyone game with the 55EF9500. I was looking at this TV but it seems the input lag is questionable.


Any gamers here want to chime in?
To also chime in:

Been gaming on it no problem since I got it in october last year.
I play very seriously in online FPS like Halo 5, R6 and Destiny.
Has not been hurting my KD due to any possible increase in input lag. Still wrek kids just as hard as I did on my previous set (which was in the mid 30's ms input lag). Including in fast-paced twitch style game-types like Swat in Halo.
Been playin the division and it looks and plays great.
I dunno how it'd fare for games like Killer Instinct/Mortal Kombat.

Would I like to know for a fact in the back of my mind that number was lower? Sure, but as it is I've only noticed it with timed button presses in Tomb Raider, but I've never tried that game on a different set to know what it would be like otherwise.

I had to put the set on Game Mode, and set it to PC and also make sure HDMI port was labeled PC - otherwise the delay is noticeable.
I'm using HDMI 1 and as Buzz's results found, that one had lower input lag across the board, so beyond a meter issue, I hedged my bets and use that directly to my Xbox and have sound out via optical from Xbox to receiver.

First few days playing with it I couldn't get over how good it look compared to my previous set (Samsung Plasma).
Colors explode off the screen and 3D models have added depth due to the ability to display true black.

Now I just need to upgrade my PC so I can play games @ native 4K. :p

This is also what I've been wondering. If it would (visually) accept the rec2020 input better by just using standard gamut and bumping up color a bit. It wouldn't map any better OOB when metered, but that way it can avoid the higher saturations that are most noticeably wrong upon viewing. Would be kinda sad though as wider color reproduction was something I was excited for in content. But with colors properly calibrated in rec709 on my set for 1080p disks, I'm certainly not disappointed that I can't reproduce Highway Sign Green :nerd:

I believe that is the reason based on meter readings relative to the desired color space.

Can someone clarify on this thread??

http://www.avsforum.com/forum/166-lcd-flat-panel-displays/2226162-uhdtvs-not-supporting-2160p-10-bit.html


All HDMI ports on many UHDTVs aren't created equal and manufacturer datasheets are vague at best. Just recently, when calibrating my clients' televisions, I started testing the 4K inputs on UHDTVs to see what resolutions, colour spaces, and bit depths could be displayed and which ones would give me the “no signal” indicator. What began as a little test with one manufacturer has become a big thorough test with all. The UHDTVs tested at this point are demonstrating the same performance issue: no 10-bit support for 2160p over HDMI.


In their literature, these panels are advertised as supporters of deep colour and in some instances even have a menu function to turn on support (and restart the TV). At 1080p 10-bit is supported, but not with 2160p. Is it a fallacy in advertising or on the belief of the manufacturer?


All of these TVs will support 1080/60p 10-bit (and will take a 12-bit signal, too), but they all give us a blank stare when the resolution is switched to 2160p at 24Hz or more. This is a bit surprising to me because of the 10-bit deep colour advertising. It also raises concern because the UHD Blu-ray format is native 10-bit and would require the user to select 8-bit output, thus eliminating a major benefit of the format. I will also mention that these tests were done at all colour spaces of 4:2:2, 4:4:4, and RGB 16-235.


I can't speak for streaming content; if the streamed signal is 2160p @ 10-bit, then the TV may just very well display it as such, and thus manufacturers can advertise 10-bit performance at the panel. Although I suspect many of us early adopters will be concerned about inputting 10-bit external sources for the highest quality signal.











LG 65EF9500

All four HDMI inputs are HDMI 2.0 and support HDCP 2.2.
Selectable Deep Colour option for all HDMI inputs, but does not accept 2160p at 10 bit. New diagram showing an image of 4:4:4, 4:2:2, and 4:2:0 when over this option. Maybe that's LG's definition of deep colour?
When OLED-light set to 85, the TV achieves ~300cd/m2 with a 100% white window in ISF Expert mode calibrated to D65.
All four inputs accept these signals:

Resolution | Output Color Format | Output Color Depth
2160p60 | YCbCr420 | 8 bit
2160p59 | YCbCr420 | 8 bit

2160p30 | RGB | 8 bit
2160p30 | YCbCr444 | 8 bit
2160p30 | YCbCr422 | 8 bit

2160p25 | RGB | 8 bit
2160p25 | YCbCr444 | 8 bit
2160p25 | YCbCr422 | 8 bit

2160p24 | RGB | 8 bit
2160p24 | YCbCr444 | 8 bit
2160p24 | YCbCr422 | 8 bit

Robert is the same person who early in February told me that the February build EF9500 displays and TVs had the banding problem fixed. Not at all.
Be careful, Robert will send you a threating PM about defaming and ask you to delete your post!

Will be interesting to see what you decide and what adjustments you make if you decide on using standard instead of wide. I don't have a meter, so all I would adjust is color and tint. The problem with HDR, we really don't know what it's suppose to look like, and this tv, like many of the early HDR capable tv's, never will be able to accurately display the color for HDR.

No not at all, I wish it was a viable solution.
The new Lumagen Pro 4444 is said to be able to process 3DLUT's for UHD, but that is still in the Beta stage.

Also there is HTPC's (madVR) that may be able to process 3DLUT's for UHD, but that I think is still in Beta stage also.

How is black crush on these displays, I can handle it in tv/movies but not in my gaming
You can modify your brightness and gamma settings under the game mode preset, and on top of that almost every game nowadays also has individual brightness control. Although it can occasionally take a minute to find the right balance, I haven't had any issues. Obviously if you are willing to sacrifice more of the true Black abilities you really don't have to worry at all. But like I said, I've been able to find good balance for gaming.
