Hello. I've just bought a brand new Transformer, and I'd like to as a question. While my light bleeding problems are minimal, and I've been blessed with excellent battery life, I'm having a small problem with the display. My screen is plagued by evenly spaced darker/lighter vertical lines while in portrait mode (or horizontal while in landscape mode). They are very subtle, and can only be seen on a vertical background.
I can also notice dark lines moving across the white background while looking at the screen using a camera. Also a minor inconvenience, and it isn't noticeable if you don't try REALLY hard to find it.
I've searched all over the internet for info about this, but with no luck. Is this an inconvenience of the IPS panels, or a hardware defect?
Thanks in advance!
Hi
I have exactly the same problem as described in this Note 10.1(2014) post:
"Hi there,
not sure if it is the same thing. No matter what [Display/screen] mode I choose, yellow comes out quite muddy and dirty, I am not able to get a clear, nice yellow out of the screen, always turns out like brownish. Is this common? I had read about "accurate colors" which isn't the case with my unit. Other colors seem more natural to me...
Thanks in advance

On my screen, all other colors than yellow/orange look great....
But the difference in yellow/orange - when compared with a Galaxy s4 or iPad - is clearly visible. Have a look at a Shell, Tide or DHL logo or compare with the yellow in the chrome logo.
Does anyone experience the same issue?
yellow/orange color problem example picture
Here is an example of the different yellow colors between Note Pro 12.2, Galaxy S4 and iPad2 in a picture (out of camera).
Similar case to the lenovo Yoga 2 Pro "yellow correction"?
I hope it's not similar to the Lenovo "yellow correction" problem. The display of the yoga 2 Pro has similar technology as the Note Pro and many Lenovo users reported the "yellow" problem (a 116 pages thread in their support forum...):
"“The Lenovo Yoga 2 Pro utilizes a Samsung LCD panel with a Pentile Red-Green-Blue-White (RGBW) pixel matrix, as opposed to a standard Red-Green-Blue (RGB) matrix on more conventional LCD panels.”
=> look for "Yoga 2 Pro 13 Yellow Color Issues" at the lenovo forums,
the pictures in the first post are very similar to mine...
The good news: It seems that a BIOS Update by Lenovo helped to solve the problem there.
I just found this issue.
In my opinion, samsung put the CMYK filter in the display software . this make bright yellow in RGB turn into "process yellow" in CMYK (make the yellow is more brown.) which is more accurate for printing .
but on the LCD screen like computor and other mobilephone, it look dull and too dark.:crying:
Might be something wrong with yours. Yellow seems ok on mine. Sm-p900 vs Nexus 10

i have another color issue but with pink color i have patches of pink color in the bottom of the screen?
Evidently. The NotePro has an LCD screen, and the S4/S5/Note 3 are AMOLED.
You can't expect the two to look alike.

Hey guys. Sorry for my english. Have you found anything else? I'm having the same problem here. Some sort of greenish yellow, but no problems with any other color.
Have you returned your tablet for RMA?
Thanks!
Hey guys. I noticed that whenever I pull down my notification / settings bar the yellows displayed on background stuff looks normal. This is kind of an annoying find, as it shows that the note pro is capable of correct colors
Same problem. Is there a solution?
I know that its a old thread, but is there a solution to that problem?
yellow on the Note Pro 12.2 looks more like mustard.

Don't compare an LCD display to a LED display, especially an AMOLED or a Retina display.
The color gamut in an AMOLED display is 4 times that of an LCD display. That means an AMOLED display can display 4 times more vibrant colours than an LCD display.
An LCD panel will never display the same level of colour vibrancy as a LED panel. Which is why LED panels are so much more expensive. (A NotePro with an AMOLED display would've cost over 2000 quid.)
There's no solution because there is no problem. It's just how an LCD displays yellow.
Using a colour correction app won't work, because you can't increase the vibrancy.
No, I'm not trying to sell washing powder, just trying to understand an issue I've had now with two Pixel 2 devices, and one that I posted about on the colour saturation and accuracy thread on the Real Life Review boards previously.
My first Pixel 2 arrived in December and I was immediately underwhelmed with the colour balance on the display - regardless of configuration options. Whites were very yellow - not as bad as when the Night Light was on, but far from white. So I returned the device, and a new one arrived a few days later. My second Pixel 2 is undoubtedly much better than the first. Not only was the colour balance better, it was also noticeably sharper when compared side by side. However, it still has a definite yellow tint in the whites, and some images seem to show this more than others - for example, flesh tones in the otherwise superb photos (when viewed on the device) look odd.
It's most noticeable for me when I have a nearby monitor or screen to compare. Individually the phone does not look so bad, but the whites on my monitor, laptop, tablet and even old phones are significantly whiter. (I'm not helped by the fact that I work in front of a screen all day - so I'm rarely able to avoid the comparison.)
Hence the question - both my devices have had a distinct yellow tint in the whites. How about yours?
I'd really like to keep the phone - because pretty much everything else about it is great. However, it's not a cheap phone, and because of that I'm not sure I should be making such a compromise on the display.
Any feedback appreciated.
I went to Best Buy and looked at the Pixel 2 they had there, and it had a similar yellow tint to the one I had that I RMA'd, but I don't think the tint was as bad on the one at Best Buy as it was on the one I had.
To get a comparison I just loaded the Play Store app (white background) and compared to a sheet of laser printer paper I had on my desk (under fluorescent lighting in my office). I'd have say my whites were a bit colder (i.e. less yellow) than the paper appeared under these lighting conditions.
I tried changing colour mode, but that didn't seem to have a dramatic effect on the white point, though "saturated" looked a little different - I'm not sure whether I'd describe it as "warmer" (more yellow/less blue) or just having slightly more green, but there was a very small change in colour temperature in that mode. I use "natural" myself anyway.

Thanks for the feedback.... I'm using natural mode too - boosted, or saturated just make the whites more yellow for me. It's subtle - but noticeable.
I've also noticed yellowish whites comparing it to other screens. Even my old N6P had better whites. I don't know if it's a generalized issue we should worry about, or just stick with it.

It's just how these screens were tuned. They are much warmer than LCD screens and look yellow when u compare to basically any other display. It's a feature, not a bug. Stop comparing and you won't notice it ?

You're right of course, I need to stop comparing... I just got a bit paranoid after my original RMA'd device's screen was so poor. I think I'm going to stick with it.
Amoled or OLED screens are overrated, Poco-f1 screen doesn't lag behind in any circumstances.:cool
Yeah, but it drains more power even with an all black setup.

Lo. I wonder if you have ever used a Samsung device with sAMOLED display? Just place both a sAMOLED and a LCD display side by side and see the difference.

Previous phone was Galaxy S8, I don't find much of the experience difference.
IPS LCD and AMOLED displays has advantages and disadvantages
IPS LCD has that AMOLED doesn't have:
-Sharpness and Clarity is good
-Natural Colors (AMOLED is little saturated on Colors)
-Can recover to accidental burns or screen burns (AMOLED cannot recover on screen burns thus leaving white marks)
-Longer pixel life (AMOLED's pixel quality degrades over time)
AMOLED has that IPS LCD doesn't have:
-Improve battery life as turning off pixels without backlight (Good for Dark Themed apps, videos, photos)
-Brightness and Contrast is good
-Good Viewing angles
-Always-on Display (IPS LCD cannot support this due that it uses backlight rather than turning off black pixels thus increasing power consumption)
Verdict:
No clear winner. It is the preference of both users and the manufacturer on what type of display they want to use. This is why Xiaomi uses IPS LCD Displays because it is cheaper than AMOLED ones. The target is being a budget flagship-tier phone thus achieving it.

Yeah best done with a gray picture so you can see the burn in on the oled. After some burned oled I only buy IPS screens.
I can't understand the "true black" hype as there is no such thing in real life and as the brain even can interpret white as black if the contrast is right.
As long as OLED tends to burn in, it's a no-go for me.

Three reasons why Xiaomi should go the OLED route :
True black :
Here's an example of true black :
On you Poco, go to full screen settings and turn off the notch. Now to two top corners are rounded as the bottom ones. Now go to a dark room, as if you were using your phone at night. Well you still see the top corners of your phone's screen on. Of course that color is black, but it's awful. (In a dark room you see it better, but I see it in the sun as well).
Always-On-Display or AOD :
You can't have AOD on an ips panel. End of the story.
Brightness :
Outside in full daylight, I constantly have to block sunlight off the screen and put it right up to my face to see what's on it. OLED is way brighter.
Bonus :
Dark mode is here in the MIUI beta and coming to everyone later. MIUI 11 will have it out of the box. This means phones with OLED screens will have a great battery advantage over ips.
Also - OLED and AMOLED tend to use very low PWM which may give you a headache/migraine.
For instance - Xiaomi Mi 8 with AMOLED panel has backlight that flickers at 100 Hz, Samsung S9+ has AMOLED panel with backlight that flickers at 215.5 Hz while Pocophone has a backlight that flickers at 2315 Hz (source - notebookcheck reviews)

They have pros and cons, both of them. While sAMOLED has better contrast, black colour, and often better viewing angles, IPS has most of the time better colour accuracy and it's better to look at while exposed to direct sunlight. I mean, you use the one which suits you the best. Unfortunately, Xiaomi uses probably some cheat IPS panels, so they look worse compared to some higher end phone with IPS panels.
True black is just an excuse ??
And amoled panels aren't bad or anything. They are just over rated and people say. Amoled- amoled l. Look it's not that a big of a deal.
And battery consumption difference is just minor
Like 3 or 4% through dark mode in amoleds too
So what's the hype
I just said Poco-f1 LCD panel is just as good as OLED
If not it's only a difference of 19-20
Nothing more
Ill always prefer lcd. When i bought the phone i had to keep it on over night for data transfer via wifi as i had no pc , to keep the wifi transfer app alive i had to keep screen timeout to never, on morning i noticed lcd retention all over the screen ?(similar to amoled burn in but not permanent), had it been an amoled surely my screen would have to be replaced day 2 of buying a new phone. I had to use the phone screen a lot but the Lcd retention went away completely after around 8 hrs:victory:, so no amoled ever unless they fix burn in!
lol this thread is like a circlejerk. my poco f1 has crappier display than my a2. it has the lowest quality lcd possible. this comes from someone who has used over 37 android smartphones throughout this decade with many being top tier flagships.
But poco F1 has a comparatively dim display even for an LCD. Under heavy sunlight it becomes difficult to see the display. On S10 for example you can clearly see it in any condition. That is why they bumped up the brightness in the poco X2
Im facing some display issues in my poco x4 pro 5g Indian variant
in dark mod or when opening a plane black photo in gallery the display not becoming fully black I can see some dark white areas in display but in certain brightness level only (20-50%) and little bit screen flickering.
No issue with always on display black areas are completely black
Is that a ui bug or hardware issue?
anyone facing the same?
Yeah I also got this issue. I don't have a link but you can look for "Oreo Colorizer" I don't specifically know how this works but I think it's a software issue.

This has a couple of solutions, sometimes it works, both options work for me tho. but i rarely or never use darkmode cause the blacks are 100% black and looks ugly in my opinion, i rather have a dark gray dark mode, but still i wouldn't use it that much
the screen is the best screen you'll get for mid range phones the screen pretty much is a flagship level screen. So i don't care much of the spots cause colors, contrast, the deep blacks it gives are perfect.
POCO X4 Pro 5G AMOLED screen shows some bright spots on dark/black images.
Hello everyone! I just got my POCO X4 Pro 5G phone yesterday. I absolutely love using it to bits. However, I noticed that while browsing through content on medium (40 - 50%) brightness, the phone does not actually go fully dark. Some parts are...
