Screen and Backlight quality?

Hello,
The display has a great resolution and has a wonderful size, but what can we expect from the screen brightness and contrast?
There is a review where the HD is compared to the Iphone 3G and the contrast and brightness of the iphone is even better (colors are stronger). Will the sold blackstone offer a better quality display contrast / brightness?
thx for any reply.

It's not the screen itself in which the IPhone is superior. Both screens (in darker situations) have quite similar brightness/contrast/color strength (looking at the Diamond and an IPhone 3G right now), and the Diamond is a hell of a lot sharper with 3 times the PPI.
But outside, on pictures and in well lit videos, the screen of the Diamond, Pro and HD all become a bit glared because they do not reflect all of the light, like the IPhone's glass screen, or the Blackberry Bold. They pick up some of the light which makes it harder to view the screen which is behind the top plastic layer, hence it looks as if their contrast is worse than that of the IPhone, which is not always the case.

In terms of DPI/PPI the HD will be lower than the Pro/Diamond I'm assuming since the horizontal resolution is the same even though the screen is wider and the vertical resolution is 'only' 160 pixels more in a screen that is a good bit longer than the Pro/Diamond.
Is this 'loss' of DPI/PPI in any way noticeable?

It is noticable, as soon as you stick your face into the screen and have good eyes The PPI is lower yes, but still much higher than say the IPhone (about 2.5 times higher). Since even on the IPhone you hardly notice pixels, the HD screen will still be tight as a drum, print quality for sure. The difference between the HD and the Diamond really is minimal.
Also, the huge screen means you will not be staring at your phone from up close since you have so much more real estate, you can hold it further away. Also I like the fact that the PPI have decreased in the width, because that makes all WinMo user interface bigger which is a plus imo, I really like the Diamond but their statement that you will only need one finger to control everything is BS.

Screens: LCD vs AMOLED

The one thing I wish the EVO had going for it is an AMOLED screen. I'm coming from a Nexus one with said screen, and it's gorgeous. Almost useless in direct sunlight, but gorgeous. Now their was an early Sprint ?Coming Soon site claiming the phone had an AMOLED screen http://www.androidguys.com/2010/03/28/sprints-htc-evo-4git-sizzles/ ---but this was prob an error. My question is: is their a huge, noticeable, difference in the two types of screens? EVO owners, give me your opinions!

Just had a live evo in my hands, and the screen is a beaut. I wouldnt worry about it not being AMOLED at all.

The screen is really a great screen.
I really don't notice much of a difference in colors / contrast / etc when compared to the ZuneHD, maybe it's the higher resolution / size that makes it look just as good.

meh, on the whole, AMOLED is all hype no show

AMOLED is trash I have a Nexus and an Evo and in direct sunlight my EVO is noticeable, AMOLED drains battery, LCD saves, colors are sharper but not brighter on AMOLED, brightness all the way up they both match up but the nexus(AMOLED) has a sharper scene
all in all not a big differ and Evo screen (IMO) has a better screen
1- colors are the same but sharper in AMOLED
2- direct sunlight LCD wins
3- colors are both bright
4- LCD battery saver
just a few details!

I thought that the amoled was more efficient.. so better than lcd

Phone Scoop comparesEvo screen to Nexus One Amoled
See below for review comparing the Evo screen to the Nexus One Amoled
Here is the link to the full article.

Screen
The screen on the HTC Evo 4G was, at times, a bit disappointing. Under medium indoor light, the screen is crisp and clear. Text looks sharp and legible and the dark, contrasty interface looks polished. Outside, the Evo 4G couldn't hold up to bright daylight. This made it tough to use for normal email and calling tasks, and nearly impossible to use the camera, since you have to tap an onscreen button to take a shot. In almost every way, the screen fared better than the AMOLED display on the smaller Nexus One. It was a bit brighter with warmer colors and much better outdoor performance. But it could still stand some improvement.

Incorrect, AMOLED has no back light and consumes roughly the same power that a TFT LCD uses just on the TFT portion of the screen. The TFT Portion of a Active Matrix OLED screen controls light on a PerPixel basis, illuminating each OLED pixel at whatever color is required vs LCD where the current is constantly on(except in a pure 0 0 0 black pixel) and controlling the Liquid Crystal portion rotating the LC to whatever degree to allow the backlight(A large % of the consumption) to shine through at a given color. And because of AMOLEDs aforementioned lack of back light it uses significantly less power.
I'm also confused as to what you mean by "color sharpness" Are you talking about the actual edge sharpness of an image or the color reproduction.
In which case the color reproduction on a AMOLED is more SATURATED not specifically more accurate, though the increased saturation makes the image appear better on average because most people enjoy over saturated images. The contrast ratio, which is the ratio of black to white, e.g. when a TV says it has a 3,500:1 contrast ratio then the luminance of a pure white pixel 255,255,255 is 3,500 times higher than that of a pure black 0,0,0 pixel. AMOLED displayes typically have a much higher contrast ratio due to the lack of a back light and the fact they can produce much "deeper" black pixels.

AMOLED actually bugs me, not only are they useless in direct sunlight(which I find myself under quite often) but it feels like colors are often OVER saturated, like the reds and oranges on my friend's Incredible look awful while I've never had that with my Hero, some colors on mine might be washed out but I'd rather have that than have a giant hodgepodge of colors on an AMOLED.

Another thing to consider is AMOLEDs "burn in". That means that pixels that do not change on the screen for a long time tend to burn in and show permanent shadows. This happens on the status bar a lot since it is nearly always displayed and unchanging.
Here is a thread of NexusOne owners documenting it.
http://forum.xda-developers.com/showthread.php?t=673513

As of last week I just switch over from At&t to Sprint wireless. I had two lines on my contract, wifey with the Samsung Moment and myself with the HTC Hero just to hold me off until the Evo release.
From what I thought isn't the Samsung Moment screen also uses the Amoled technology and the Hero is LCD?
Side by side comparison from low brightness to 100 percent, the Hero display looks so much better quality wise compare to the Moment. Hero seem more saturated and crisp whereas the Moment IMO seem much more dulled. Especially in the setting menu with the black background, the Moment is kind of like greenish black whereas the Hero is spot on black. Outside I'm having a very difficulty time navigating around Moment (brightness all the way up) whereas the Hero is still manageable.
By any mean I'm no expert in this display stuff but this is just my own little comparison of what I've seen between the two display.

Anyone know if the Evo screen is transreflective? A related question would be, is it even possible for AMOLED to be transreflective?

I compared my Evo screen with my old Hero screen and the Hero was a little brighter and with darker blacks. Even between LCDs there are differences.

Note 12.2 screen has 4 Million less subpixels...

The Note 12.2 uses a pentile [RB][GW] subpixel layout vs the TabPro 8.4 which has full [RGB].
Pentile screens use just 2/3 of the subpixels compared to full RGB.
Accordingly subPixel counts:
Note 12.2 ... 2560x1600x2 gives about 8 million sub pixels
tabPro 8.4 ... 2560x1600x3 gives about 12 million
Disappointing for a device priced so high with a 'Pro' tag?

i believe that the actual experience of using the tablet and getting the best out of it matters more than the on paper calculations

I have a Nexus 10 and a Note Pro 12.2 and can't tell any difference in pixel density so quit complaining about paper specs. It's a great tabet!

Turn that in to PPI and it doesn't look so bad. The gross PPI for the N12.2 is 247. The addition of the white sub-pixel (25% of the total count) reduces the RGB pixels by 8% each leaving them at 227 PPI each. The iPad Air is at 264 PPI and the net RGB for the N10.1-14 is 274 (gross is 299) resulting in the N12.2 having 14% fewer RGB pixels per inch than the iPad and 17% less than the N10.1-14. It's 24% less than the N10 which uses a RGB stripe display. Whether those PPI reductions are comparatively noticeable depends more on individual visual acuity and the distance the device is viewed from than anything else. Some reviewers commented on the display being less sharp when compared to the Tab|Pro 8.4/10.1 and N10.1-14.

Same here. No perceived difference in sharpness/quality with my Nexus 10.

All these calculations are a waste of time and effort. I can't tell the difference side by side so no one is going to be able to honestly perceive that one is better then another... These kind of arguments and numbers are only for haters or people who can't afford a device but want to convince themselves they really don't want it because of some technical specs that can't be perceived in real world usage/conditions.

Look it is what it is.
Samsung used a pentile screen in the 12.2 . Pentile screens have 2/3 of the sub pixels of a normal RGB display.
The display quality of the TabPro 8.4 is incredible, 1078 sub pixels per inch,
whereas the 12.2 pentile display clocks in at 494 sub pixels per inch.
As others have noted, the 12.2 Note screen is more than usable, but it's inferior to a full RGB display.

So you are not getting one ?!
As I said actual experience matter than paper specs and calculations etc. I have seen no one disappointed about the screen not on here or in a YouTube video but you . everyone is charmed by the beauty of the screen and happy with it . those calculations are not a deal breaker for anyone around here and if you are not happy with what you would get with the note pro you could simply get the 8.4 tap pro its a personal reference .

Sorry but you are being stupid. Stop analyzing the specs and actually try out the devices. No way you can perceive any difference under normal operating conditions. I truly feel sorry for you...

It's an lower quality display. The difference can be seen, and stated and is unexpected in a premium product.
If your charmed by the product or unable to see the difference, all the better.
Maybe Samsung has judged its target audience correctly.

Actually the way pentile and rgb stripe displays render information is totally different. Rgb use an entire pixel (rgb) to create an image. Rgbw displays render on the subpixel level. The pixels actually have no locked in grid they must conform to but rather work with all those around them to render the same resolution image as rgb with 2/3 of the subpixels. There is no discernable difference except that rgbw actually conforms to the process of the human eye better and thus can achieve better color parity with real life.
PenTile® technology is biomimetic, meaning it is designed to compliment the complex mechanics of the eye-brain system. As a simple example of eye mechanics consider how the eye utilizes the color blue. The eye has cone receptors that sense color and brightness, and discern patterns. These cones are sensitive to different wavelengths of color—primarily red, green, and blue. The blue cones detect mostly color (chroma) information, while the red and green cones do most of the work resolving images by discerning luminance, edges, and structural details of images, as well as contributing to color vision. The red and green cones are used independently, each cone seeing a "dot" of black and white—ignoring its color to produce high resolution luminance perception—and are used in opposition, comparing the amount of red versus green, to produce low resolution color perception.
If there was an obvious disadvantage I doubt one of the largest and most successful electronics companies to ever exist would not use pentile. Or have you all forgotten that the NOTE 3 pentile is hailed as the best screen on a phone period (with regards to new 2k screens coming this year) even beating out all lcd rgb competition?

PREACH.
The only other image related difference, I believe, is that the tab can record HD video at a higher fps. The camera only weighs in at a craptastic 8 MP, and I don't use my tablet, of all things, to film video. The s-pen, on the other hand, is fantastic for graphic work.

How is this stupid? We are not talking about a $100 or a $200 device; this is the most expensive Android tablet where EVERYTHING should be premium. When the build quality is already meh, not having 2560x1600 at standard RGB stripe for a LCD is a kick to the teeth.
The comparison with the Note 3 is asinine, because this is not 1080p AMOLED on a 5.7" screen where the tradeoffs with Pentile are more than worth it. 2560x1600 RGB is only 227 ppi, Pentile reduces it to 2/3 to 150 ppi. The claim you make that people can't see the difference like Retina iPad is ridiculous.
My brother has the 12.2 which I have actually used it so don't use the "you didn't tried it out hurr hurr" excuse to shut people up. Straight edges are clearly blurrier than my iPad Air. But hey if you like Samsung to continue selling you inferior specs at high prices be their guest.

But at the end it's not the pixel density. If you get the same effect with new technique, you don't need so high density. But as you said you see the difference in straight edges so probably buyers should then first check the screen do they see the same or not.
Sent from my N8000.

I have the note 3, note 10.1 2012 and the note pro 12.2, the note pro is much better than my note 3 and my note 10.1 2012 combined. If you want to complain about ppi, then you should complain about the first note 10.1. 1280 x 800 on a 10.1 inch screen vs 2560 x 1600 on a 12 inch screen. Considering the first note 10.1, that is a screen upgrade to me.

Good, I hope you don't buy a 12.2 for this reason. No one really cares and it's your loss... I firmly stick by my claims, I have better then 20/20 vision and at normal viewing distance (i.e. 18inches or so) it's impossible to tell the difference. You go ahead and stick face right up to the tablet screens and compare them side by side finding that under non normal usage it's technically possible to see a slight difference if that is what you need to do. 99.9% of people who want this tablet have no issue with the screen cause if you take away the specs and evaluate the screen under normal usage conditions it's as good as anything on the market. If you think your little online rant about the resolution is going to force Samsung to make a screen that meets your specs you need a reality check. I'm going to enjoy my Note 12.2 and in a year from now Samsung will likely release a newer upgrade model with a "better" screen (as that is what happens every year) that may meet your technical requirements. Until then you enjoy your little iPad Air and I'll me enjoying my Note 12.2!

How is this thread still going? Either you buy one, or you don't. I bought it, and I'm never looking back. It has all the functionality I need, plus things I've not yet gotten around to messing with. It's an awesome tablet. If subpixels are what you're in the market for, then you have done your homework and know this isn't what you need.
This is what I need. Very pleased.
Thank you, and goodnight.

Samsung FIRMLY believes that pentile is a better screen technology than lcd they are the ones driving it's development. It is more akin to how the human eye actually works and it is easier on the eyes. The number of sub pixels is the same just one per every four is white, It is 30% more energy efficient and it requires fewer sub pixels to display at the same resolution, the human eye will see it the same as a higher resolution. To be technical though gentile displays have ZERO sub pixels. Each individual subpixel is rendered separately. They are not in pre defined groups and can be combined into any number of logical pixels. So technically the screen is using 12,288,000 individual pixels.*
conventional RGB stripe displays render (draw) images by assigning a color and luminance (brightness) to an entire RGB-triplet as a whole pixel, adjusting its three RGB subpixels to set a single addressable point. Images on a PenTile RGBW™ panel are subpixel rendered, meaning they are drawn at the subpixel level (the individual points of light), rather than to the whole pixels of an RGB stripe display. In fact "pixels" in the traditional sense have been eliminated in PenTile RGBW™ displays; individual subpixels are not restricted to use in one pixel group, but instead participate in multiple "logical" pixels in their surrounding vicinity.
Subpixel rendering dramatically increases addressability and enables the sophisticated image processing used in PenTile RGBW™ displays.
That is from nouyance the company that invented pentile and rgbw They also say
PenTile® technology is biomimetic, meaning it is designed to compliment the complex mechanics of the eye-brain system. As a simple example of eye mechanics consider how the eye utilizes the color blue. The eye has cone receptors that sense color and brightness, and discern patterns. These cones are sensitive to different wavelengths of color—primarily red, green, and blue. The blue cones detect mostly color (chroma) information, while the red and green cones do most of the work resolving images by discerning luminance, edges, and structural details of images, as well as contributing to color vision. The red and green cones are used independently, each cone seeing a "dot" of black and white—ignoring its color to produce high resolution luminance perception—and are used in opposition, comparing the amount of red versus green, to produce low resolution color perception.
The PenTile RGBW™ layout uses each red, green, blue and white subpixel to present high-resolution luminance information to the red and green cones, while using the combined effect of all the color subpixels to present lower-resolution chroma (color) information to all three cone types. Combined, this optimizes the match of display technology to the biological mechanisms of human vision.
Other human-vision factors such as the logarithmic representation of luminance values, variable resolution between the center and edge of vision, and the separation and compression of brightness and color differences are also exploited in the design of PenTile RGBW™ displays.
The human eye perceives the resolution of the PenTile RGBW™ panel as the same as an equivalent RGB stripe panel, yet the PenTile®*panel uses one-third fewer subpixels. Consider the figure below to understand how this is accomplished.
At the top is the PenTile RGBW™ layout; at the bottom RGB stripe. The circle at the bottom center demonstrates the finest pattern of vertical black and white lines an RGB stripe display is capable of rendering. This requires three columns (R + G + B) be turned "on" and an equivalent width of three columns be turned "off" to write one cycle of a black and white line. From a suitable distance this collection of color subpixels appears to the eye as a white line.
The top center circle shows the equivalent pattern of vertical black and white lines written to the PenTile RGBW™ layout. From a distance the array of color subpixels in two columns will appear to the eye as a white line, identical to that generated by the RGB stripe layout, and the following two columns will write the corresponding black line. With only four columns being used to accomplish the same linear cycle that required six columns for legacy RGB stripe, two columns are saved. Hence, PenTile RGBW™ technology maintains the same resolution with one-third fewer columns, one-third fewer subpixels and one-third fewer transistors in the array. This results in wider columns and improved aperture ratio (ratio of transmissive area of a subpixel to the total area of that subpixel).
The circles on the right of the figure demonstrate the finest pattern of black and white lines which may be written horizontally to RGB stripe (bottom) and PenTile RGBW™ (top). Note that both layouts require the same number of rows for horizontal lines.
from this information we can see that a rgb display and a rgbw pentile are equal in displayed resolution and the pentile is more efficient. In black and white images and full color media Petite and rgb are 100% indistinguishable and only when displaying text against a fully saturated background (color text against a solid Colored background) or a sudden transition between two colors can a difference be seen and these are almost unnoticeable on high density displays like the Note 2014 or Note 12.2 pro. What you call drawbacks to pentile I call progress and efficiency. If I can't see a difference there isn't one. Only mine is bigger and more useful with better battery life. I owned the 2014 and work around and begrudgingly sell ipad airs on regular basis. I also have perfect vision in one eye and nobody I have EVER had come into my store has seen the 12.2's Screen as anything short of magnificent. Yes I suppose if you get close enough to your screen that you can barely focus on it that You could see a difference but ya Know I have a life and at normal viewing distances it is flawless. I mean I guess I better not buy a laptop anytime Soon since their dpi's are lower than an ipads right? Or if I want something really worth owning I need that 20" 4K tablet. And my TV is only 1080p? Its 50" THAT'S ONLY 44 DPI OMG I BETTER TRASH IT!!! Forget viewing distances I can't believe I enjoy this crap. I need at least an 8K tv to get a good dpi now I just need to wait about 6 years before I can own a tv again. And a 100" tv? Give me 16k and we can talk.

AMOLED whites look the best they ever did on the Note 5

Granted, they still can't reach the same level of good looking brightness (even if they are "accurate") as top-end LCDs like the iPhone panel, they're getting closer with each generation. It sucks the whites only look best in high dynamic contrast environments with sunlight. AMOLED screen efficiency might take a couple of more years before it can hit 500 knits of brightness on pure white content (or above 70% APL) on maximum manual brightness and not autoboosting

I agree, side by side with my S6 the Note 5 is much cleaner/brighter/sharper.

I have an i6 for work and a Note 5 personally. I much prefer the Note 5 screen in all environments.

I used iP6, G3 and now the Note 5. For now Note 5 has the best display ever. Colors are popping out of the screen and the blacks are, oh man.. There is nice amount of sharpening too, not too much like the G3.
But the whites.... They are a litte bit weird man. If you directly looking at the screen, the whites are white. If you looking at the screen with different angles, they start to turn a bit yellowish or bluish white depending on your viewing angle.
But not that much of problem, i dont even bother or care it. I'm loving the screen

Thats the biggest trade-off with AMOLED's. But, it's more than worth it for everything else we get though compared to LCD

AMOLED screen does not need as high a brightness as LCD screens due to its high (infinite) contrast ratio. Example: people were surprised to learn that the Nexus 6's max brightness is around 250 nits because they were accustomed to brightness readings of LCDs. This is another area where reviewers created reality distortion field in favor of Apple products, and seeing everything else through from that distorted viewpoints.
Do note that I do not dispute that the higher the brightness, the better screen is. I am saying that at the same brightness, AMOLED screen will always be more legible and pleasant to the eyes in changing environments. Comparing the two technologies in the absolute and judging one to be superior is not a smart move.

Lol nexus 6 screen was garbage. Some leftover from below par quality amoleds that samsung doesn't use on its phones.

Ya, I played around with a Nexus 6 at an AT&T store and held it next to my Note 5 with both at max brightness and my god the Nexus 6 had a ridiculously yellow tint and had the most severe burn ins compared to all the other amoled devices on display in the store. And the difference in max brightness was so significant it looked like the Nexus 6 was at min brightness next to my Note 5 when both were maxed out.

Mediocre - Subpar screen quality

My 32/3 Mi Max just arrived today, not too happy with the screen. It seemed so dull, some leaks on the edge. No competition between AMOLED screen and this. But the 7' LCD of 1920x1200 mediapad X2 is still a height better than this. Heck, even redmi note 2 is better. A little disappointed, glad I didn't go all out with 128/4 version.

Mine isn't that bad. Download Color Changer Pro from the Play Store. You can increase the saturation and colors in it. Mine almost looks as good as an AMOLED now minus the blacks.

The screen protector you have reduces screen quality especially black levels. 100% the cause. Most of the full cover glass for 2.5d screens does not actually adhere to the screen reducing contrast.
The screen quality is v.good although it uses software contrast boosting to make the colors nice, which can crush some details in colors.
Take off the screen prortector and show the same photo, you will see the big difference.
Btw what case do you have?

I've made some comparison photo from some of my available devices on hand. It's horrible, They're definitely cutting corners on the screen. Even my $60 Alcatel phone looks better. My Mi Pad, and Redmi Note 2 have the same "washed out tinting" issues, but this is definitely worse than that.
Just for a note:
I took of the screen protector

Did you read what I said about your screen protector.
The screen is IPS, there will always be changes in brightness when viewing off axis. It's called IPS glow. Depending on the screen, you will see it more from different angles. Mi Max might look better at a different angle than the other phones.

Now you can see the contrast is increased and black levels are better.
This is why I hate phones with 2.5d screens. You can get these full cover protectors which reduce quality or normal glass protectors which don't cover the screen fully. There is also tpu screen protectors which will cover fully without reducing quality, but they feel a bit rubbery and are hard to apply.

I forgot to put the note on the bottom, I took off the screen protector.
All LCDs have that bleeds, glows or whatever you want to call it, I'm well aware of that. But, If you need to put your phone in an angle to get correct color reproduction, i think it defeats the purpose of "IPS" display in the first place.

IPS screens don't really have a purpose, it's just a screen type. Every type of screen has its flaw.
Amoled has image retention and must use pwm to reduce brightness. Some people notice the flicker/eye strain from it.
TN panel has inverted colors instead of ips glow. IPS still has better viewing angles and IPS glow is only noticeable at certain angles.

I have to agree that the full screen coloured screen protector is POS, just realised that it doesn't have any glue in the middle, making some gap between the screen and the protector. Gonna order some better one.
Besides the screen, it's a solid good phone I reckon. I get more than what I bargained for because it's really is an inexpensive phone.. too pampered by AMOLED I guess.

The battery life is amazing. I recently got the 3/32, currently 8.5 hours SOT and 40% battery left.
Hows the miui 8 rom? I've left mine on miui 7 for now as I've read some bad things about it on the miui forum.

There is some full coverage protectors with glue in the middle, at least for other phones. Not sure if there is one for mi max but if there is, they are very rare.

It's fresh out of the box. Haven't really tried anything yet, but I'm on 8.0.1.0 apparently. I'm not sure about the battery life.. I'm more than happy to get 6.5hrs sot. My daily driver is iPhone SE, hands down its a beast of a phone, 9 hours on time give or take.
I just ordered Nillkin glass protector for my mi max, kind of expensive, but can't go wrong with that one. Please share with me if you found any good full screen glass protector.

The big draw of the Mi Max screen is the size, not the color accuracy or black levels or brightness. It's an average screen, not mediocre like a lot of cheap Chinese Android junk but not as good as an LCD on a flagship device. AMOLED is on a different planet because of the crazy saturation and inky blacks. I've had a few phones with AMOLED and although they're great for viewing photos and videos, they're not good for web surfing or working with documents because white draws more power. I didn't have any issues with burn in though.

1. The photo attached in the first post doesn't actually have the mi max in it. I suggest you remove it.
2. Second, the comparison album you made on imgur has software buttons and doesn't actually show that it's a Mi Max, while the separately attached photo in that same post has the xiaomi rom running. The separately attached photo clearly shows its the Mi Max and the display looks great to me with no issues.
My personal experience is also that the screen is great and I'm not sure where you're coming from...

In the first post, Mi Max is the middle phone. The user has installed a full coverage black glass screen protector which reduces the contrast as there is an airgap between it and the display.

I thought long and hard about wading into this thread, but after using the phone for a week I figured why the chuff not.
So, yeah, after 7 days use I've got to say I think the screen is pretty great! I haven't seen any hint blue tint I've read about in a few reviews, although, my device is much newer than the first batches and preproduction models, so that could explain it.
It's not as punchy as an AMOLED, but AMOLED colours are often way inaccurate. Which brings me to my next point, I find the screen pretty spot on in terms of colour accuracy (visually speaking at least, I've got no idea as to the reproduction of the panel on a spec level). It's definitely an improvement over my Meizu M1 Metal.
For the money, it's hard to fault this device. It's by no means perfect, but it's 1/5 the cost of a Samsung Galaxy Whatever.

It is a bit on the blue side but just a bit & you correct it with enabling reading mode & moving slider to the beginning position.
Did my own view test today by using MX player & putting it in to the 32 bit RGB display colour format and then I played a 10 bit Hevc movie. Well the display is quite good but nothing mind blowing. Luminance is an a down side required for something like HDR but it can pass presumably if you use it in controlled darker environment. Actually with brightness set to 11 out of 15 possible (which translate into 73.3%) its good enough but if you go over that contrast and with it quality begins to go down drastically, 12 (80%) is top & even that I would call a compromise. Don't be missed by this for a mobile phone LED display this one is perfectly fine, not a stellar one nor the best one out there but perfectly fine. The little more brighter displays won't make much of the difference between 450 & 550 nits their is little to non difference you will be able to see in this particular case regarding LCD's, next category should be a 700~1000 nits but mobile phones & only couple of them are stepping in lower margins of that category.
At the end I just can't not to wonder if the guy who did a calibration of the display had a little problem with its eye sight because you see as much a display is on a cold (blue) side & that is minimal a tad or two the photos (with main camera) are proportionally on the opposite warm (yellow) side.
Best regards.
