if you came from a phone with 100% ntsc or an amoled you will be disapointed, the reds and greens are about 50% off in terms of accuracy the only accurate color are the blues.
the phone has 84% ntsc color accuracy only
i couldn't demo this phone before i bought it, i could have got a mi 8 for the same price with a samsung oled panel
You can tell this is where corners were cut. The color accuracy is mediocre, it leaves a bit to be desired. Reds are somewhat washed out, greens could be more refined, and whites have a blue-ish tone.

I used my old Motorola Moto G 1st gen to calibrate the screen but the Poco screen don't even come close to the Moto G screen. I think the Moto G 1st gen has one of the best IPS screen in terms of color accuracy even for todays standard.

On pixel experience keeping Blue at 97% while 100% Red and Green in colour calibration gives great colour viewing.

I wouldn't call it great, this tries to achieve an impossible task on a below average screen / display.
It somewhat tries to blnket the issue and fails miserably.

Not an app. Its an in-built feature available in most of the custom roms, its called "Live Display".
I am currently on Evo X even they have this feature.

HTC did it again but worse. Last year displays were different in color temperature but maintained similar contrast. This year the difference in display calibration is worse.
Before receiving my own unit, I tested 2 devices in the shops. The first one had worse contrast and too low gamma (less punchy brightness transition from dark to light tones). I was disappointed with the display (let's call it Type A).
Later on, I went to another shop and the display looked gorgeous. Higher contrast, accurate gamma and more neutral greyscales (let's call it type B).
Today I received my unit and unfortunately, the display was Type A display. Here are the results of the "poorer display". Unlike last year, it is not possible to determine the actual display ID by looking this up in the last_ksmg file in the proc folder under the root. The access is denied. So unless we root a device, we cannot determine the display ID.
As can be seen below, the color temperature and greyscale accuracy is mediocre. Contrast is only average. Chromaticity overall is good but red is oversaturated.
Brightness: 503cd/m²
True Contrast: 1,000:1
Dynamic Contrast: 1378:1
White Color Temperature: 7395°K
Average Color Temperature: 7417°K
Note that on this display, the i1 Dislay pro used by many press reviewers will overestimate color temperature by 5.5% on this particular display. So if you see values around 7900°K, this is broadly equivalent to the 7,400°K that I (and Anandtech) measured. UK Harware review probably also had a Type A display however the contrat values are likely due to methodology.
Although I haven't tested extensively, I can already tell that the dynamic brightness adjustment is still taking place, though it works differently v. last year's implementation. This is why the contrast values observed in the press reviews very widely between 980:1 and over 2300:1!
I will be measuring Type B displays in the shops to nail down the differences based on the same methodology (100% Voodoo Test patterns).

Apparently the HTC One's diplay latency is record breaking - measured at 46ms.
Source: Lesnumeriques.fr
It is not at the 1-20ms recommended by Microsoft but it is a great step forward considering the fact that modern devices barely go below 70ms. The previous record was held by the Note 3 with 67ms.
Newer devices:
Note 3: 67ms
LG G2: 110ms
iPhone 53: 75ms
Here is an overview for older devices:
It will be interesting to track the performance of other devices: S5, Z2, etc...

Their marketing said JDI. Sharp models came later in the year last year, early production were all JDI.
Guys how do you find the colours on the m8.... My reds are way over saturated... Is there a way to make them cooler?

The reds are not oversaturated. What you mean is the grey balance is too warm. Saturation and greyscale Balance are two different things.
None of the Displays on the M8 are overly warm. They are actually cooler than the norm. If you feel there is a red push, then probably you are coming from an AMOLED Display wich typically have more green and blue but is incorrect.
No.... What I mean is the reds are over saturated.... I have an n4.... The reds on my m8 are way off, side by side with n4, HTC 8s, nexus 7 and a galaxy tab3...m8 reds are way off, maybe I have a defective unit.... I just wanted to see if anyone else had the same issue

Do you see that on the color red? What do you mean by reds are cooler?
Saturation has nothing to do with color temperature. It has to do with the intensity of the color, not ist hue (which can be shifted toward other colors). For example, a red that is too blue move slightly towards purple and a red that is too green moves slightly towards orange.
Hence my question. If you say your reds are too cool, then it must mean they are too purple.
Saturation means how intensive the color is. If the reds are undersaturated they move towards grey and if they are oversaturated, they move towards "more intense" red. Overaturation cannot be described as cooler but you said your reds were cooler, so probably you mean your color temperature is too cool, hence greys and intermediary colors are shifted towards blue?
As you can see from the Review listed above, the M8 can have color temperature that is on the cool side (>7000K), however this varies from unit to unit, last year color temperature varied from 6,500K to 8,000K with Color temperature decreasing over time (probably because the intensity of the blue pixels decreased faster before settling).
If you feel your display is too cool, it is not a defect, it is luck of the draw. Many people actually prefered the slightly bluer displays last year because they had slightly larger contrast.but also because most displays are cooler by nature (since sunlight is warm and will cancel out the coolness when looking at the display outdoor.
The N4 had excellent grey balance, so probably your eye got used to a more neutral display. Wait a little bit and see how your perception adjusts. If you really don't like it, then return your device and purchase another one...
So far only a few reviews measured color temperature, and the values ranged from 7000K (pretty neutral) to 8,000K (cool) but it is also possible that some displays will have lower temperature (it was the case last year). I will receive my device tomorrow, so I will let you know how my unit stacks up.

Based on my test above, the reds are indeed oversaturated and the display is on the cool side, but both are independent. The reds can be oversaturated without being cool and the display can be cool without oversaturated reds.
Added my own detailed review of the display to the original post.
@puremind do you keep in mind that the M7/M8 feature dynamic contrast? maybe that's what's affecting the results?

Dynamic contrast is only affecting constrast, not color temperature. I noted that in my post (and also under one of the Russian tests in my list) and the the contrast is 1,000:1 vs 1,300:1 dynamic.
Still these results are not so good on the Type A display.
Also I did compare two units in store, so I can really tell one unit had a much much better display. Last year displays were broadly equivalent except for brightness but this year the Type A display is quite poor (by my picky standards) and cannot compete with Samsung S5's Display. The 2.1 gamma means intermediary colors are a bit washed out. The display is not punchy and has no depth. So be careful what you get! My unit will go back. This is the display type tested by Anandtech, as they noted the same issues.
How do we determine what screen we have?
If reds don't appear to be over saturated can we assume we have the type B screen?
Yea i noticed different feedback about the screen as well...sigh

Red oversaturation is not the most visible aspect. The lack of punchiness and slightly washed out intermediary colors and lack of contrast is easier to spot.
When I am back from London I will measure type B and I expect to see correct gamma and higher contrast.
If you have rooted your phone you can use ES explorer or root explorer to view the last_ksmg file in the root's proc folder. If you look for Display ID you should find it there. It will likely say JDI something or Sharp something.
However it is not guaranteed that the display manufacturer will be different as JDI have a track record of having wide variance in terms of display characteristics. Still the displays are different enough that they could be from different manufacturers.
If anyone has access to a rooted device and can do the test it would be very helpful. Please comment what your subjective impression of the screen is and provide your display ID.

Thank you,
Could you also take pictures comparing the two models if possible?
Without context it is slightly difficult to determine what exactly constitutes "lack of punchiness and slightly washed out intermediary colors and lack of contrast."
Sorry - I'm not a bit of a noob when it comes to displays and colors!

Color accuracy isn't very good, especially for an IPS panel. Definitely a disappointment if you're used to the very saturated AMOLED displays, or even higher quality IPS displays. Blacks are pretty good, but color accuracy seems, at least subjectively, not much better than that of my Moto E 2015.
Both of the sites below have measured the Honor 6x screen for color accuracy/temperature/brightness/contrast etc. No need to ask opinions. On one of the sites, you can plug in your favorite phone to see how its results measure up to the Honor 6x.
http://www.phonearena.com/reviews/Honor-6X-Review_id4303
http://www.tomsguide.com/us/honor-6x,review-4137.html
For color accuracy, the 6X's Delta-E rating of 3.28 was once again better than the smartphone average (4.1), as well as the scores of the LeEco (4.99) and the Axon 7 Mini (3.92). (Numbers closer to 0 are better in this test). Once again, the Moto G4 Plus sported superior numbers, with a Delta-E rating of 2.33.
The one area where the Honor 6X fell a bit flat was color range. Covering 114 percent of the sRGB gamut, the 6X trails the LeEco Le S3 (137 percent) and the ZTE Axon 7 Mini, whose OLED screen hit 177 percent. The Moto G4 Plus' color range was more limited.
Color accuracy isn't very good
it is moderate and can not be differentiated with end user perspective. Not all the users can really understand or differentiate this so this is not an issue here at all.
Not so good but not bad either.moderate you can say
Bright colors are nice. Feels good to watch HD movies.
not that great..but ok
Good for the price.
Colors aren't great. Videos and images looked washed out and dull.
The ASUS ZenFone 6 (2019) has a crazy crisp display. Just kidding, this is automated text so who knows if this screen is any good. So, you be the judge! A higher rating indicates that it's extremely sharp and clear, and that you cannot see pixels with your naked eye.

I'm really curious as to the screen quality. I realise its gonna be different from an AMOLED panel that I'm used to, but all the other specs are so appealing!!

I think the zenphone looks a shade darker than the other led display due to its ips
I can confirm that there is a noticeable difference to a AMOLED display (coming from the Lenovo P2) and a side by side comparison clearly shows a better contrast in the Lenovo. But I also have to say that I only noticed that after a couple of hours with the Asus when checking back on the Lenovo. The display of the Asus is good and also in the dark not too bright.

I'm having same problem. Did you find fix to that? I fear that we need to wait for update. Twitch video quality is poor too. @megamefta
Apparently the max brightness the phone can go is application dependent, in Chrome it's 600 nits and in photos or its 550 or something. Can we expect a mod or anything to make it even that is 600 across everything in the future?

Double post.
Does anyone actually own this phone here?
How is the display in the real world . ALOT of folks on youtube are saying its pretty dark . I want to get it and understand its not oled but I dont want a dark display .
Yes sir, i own it. [emoji23] From left to right- P30 Pro, Zenfone 6, P20 Pro, i was outside under the tree, max brightness.
In general: for me the display is very good, just needs to be a bit more brighter.
PS: unfortunately this picture was shot by Galaxy A5 2015 [emoji16]
I'm coming from a OnePlus 3 and haven't compared to other recent phones, but I'm impressed with this display. It can get bright enough, at least for my usage, and even though blacks aren't as black as an AMOLED display, they're still black and not what you see on some cheap displays. Is a <Samsung-flagship> display better? Yeah, but the price is also higher than the ZF6.
The only setting I had to change was the colour mode. The two pre-defined options are "wide color gamut" (used by default) and "standard", which is more like sRGB. This is completely personal preference, for me "standard" looks more what I'd expect to see, not super vibrant colours that almost look fake. Anyway, it can be changed so it's not really a problem.
I didn't use the "always on" feature on my OP3 in order to save battery, but I can see users that liked that feature missing it on this phone.

I saw it happen once, so far. I bought the phone in March of this year, fwiw.
But it is not a regular occurrence, so YMMV.
