Hello RXT Users,
I bought a new Realme XT (6GB,64GB, Pearl White) Mobile, which works like a beast.
But within a week, I accidently noticed that the true deep blacks of Amoled display actually kills the surrounding Grey colour pixels especially in videos (or moving frames).
When I using Instagram, Samsung just posted some photos. when I try to swipe one photo horizontally, I noticed that the gradient colours (White to black) are like vanished some time and and a bluish shade is appearing btw the blacks and whites.
Then I started comparing this with other LCD panel, which is not doing these weird things. I also did a side by side comparison btw Realme XT and other LCD display by playing a dark horror movie. The results came was not expected.
First things first, the picture quality, colours, contrast and viewing angles are awesome in Amoled display, But the grey coloured details which are nearer to the black pixels are missing, they are completely gone.
Example:
• Original frame in the movie - A dark room with cupboards and interior.
• Picture shown in LCD display - white blushed dark room with cupboards and interior.
• Picture shown in Realme XT - A Deep Dark Black room with no interiors no cupboards or even no walls.
I can't understand why the Amoled display takes more time when pixels changes from black to grey colours, may it's because of low refresh rate.
Can anyone please tell the display refresh rate of Realme XT and try the above tests to clarify that I am not the only one who got these weird thing. Thanks in advance.
Note: I am using Amoled display for the first time.
This is quite disturbing to know. I was planning on buying XT and returning my Poco armoured, as it has ghost touch issues and I don't need that much processor power for daily usage.
Also, with XT getting started on development I hope I won't miss Poco. But with the above-mentioned issue, I'm getting skeptical because my primary reason to get XT was AMOLED display. I don't want to get disappointed by it.
Although it doesn't has ambient display and dark mode yet but I hope it'll be there in future updates.

After reading this post I checked my xt's display for the greys in dark scenes with my le 2 LCD display and I'm pretty satisfied. I was able to see most of the details of dark scenes that was visible on the other phone. Plus I found it's very vibrant as compared to the le 2 and brightness level is also much better.

I've noticed on hands-on videos that the Droid DNA has a blue tint on white backgrounds. Some reviewers have also mentioned this and the cooler nature of the colors. Another thing I've noticed is the colors seem less vibrant compared to the One X, which was more colorful and warmer. The blue tint was the first thing I noticed while all these review videos were extolling the greatness of the PPI. The blue tint on galaxy phones drives me batty, and this one might not be that different. Do you see the blue tint on your phones? My local Verizon store only has dummies. I might just wait for the Oppo Find 5. I really like how the screen looks on that phone.
One X was uncomfortably warm for me. Too yellow which I didnt like.
DNA is little more colder but colours still pop nicely. Much better contrast compared to One X that I had. It is right balance between what we have seen with One X and SMOLED display that my Note 2 has.
There is definitely no trace of the typical blue tint you see in AMOLED displays. It is definitely whiter than SGS3 and Note 2. But not as yellow as One X. It is perfect actually. You can never judge screen seeing videos. Choice of wallpaper, camera sensor and room lighting play huge role in how things look on camera. There is no doubt in my mind, this is best display I have ever seen on Mobile. PERIOD.
Maybe many reviewers are coming from One X which was considered to have best 720P display. But frankly for me it was too yellow to be natural.
Thanks for your reply. I have to disagree with you about not using videos to judge a display though. Every phone I've bought looks exactly like how I've seen it in videos. There are poor quality or off-color videos of course, but those are very easy to notice and disregard. With high quality videos, especially when you have the phone next to other devices that you've used and know how they should look, there's no room to blame the video. Apple's displays always look so good because they calibrate it properly. HTC and others need to take a hint. At least provide calibration software onboard if you don't want to do it manually for each device.
I've had a few replacements of the DNA for various issues and I noticed that they all had slightly different calibration profiles with whites of two of them being slightly red tinted and the others being either slightly blue tinted or in the case of the one I currently have, closer to neutral but the colors appear to be slightly less vibrant. They're all over the map, so I think it's just the luck of the draw. One thing I have found consistent is poor backlighting with shadowing on different edges of the screen on different units, especially the bottom (near the capacitive buttons). The pixel density and size is definitely phenomenal, but I miss the balanced calibration and completely even backlighting (to the edges) of my 4s.
No blue tint here.

Are u sure that opx is true black amoled??
What if I say you ... that ..It has a backlight ..
Wanna verify?
Important: make sure u have brightness slider to near low levels. This backlight is not seen at high brightness levels.
Download a gallery like quickpic that lets u open a picture in Fullscreen mode so that picture fills entire screen.
Make a bmp image in ms paint in windows and fill it with perfect black. Or download from some website with hex value coding -enter zero for all numbers
Now load this picture in quickpic or any other Fullscreen gallery.
Switch off every light in ur room .make d room jet dark
Wait a few seconds for your eyes to adapt to darkness
U will see the backlight instead of black.
For more easy recognition see in peripheral field of vision, where low light vision is good. (Focus point of eye doesn't have low light vision ,am a doc.) (see somewhere else, bring in the phone into vision filed)
If u think the gallery is d problem.
Do this same thing in any other amoled phone. You will know the meaning of black.
(I did in Moto x ghost )
It's not a backlight. No AMOLED screen uses a backlight. That would defeat the whole purpose of AMOLED.
What happens is, even if the pixels are black (switched off), they are fed a tiny amount of voltage from the motherboard to allow quick switching of colors so they are never completely turned off. As a result, even when displaying black they emit a very faint glow.
I'm not sure if this only happens on pentile displays (like the one in the OPX and most Samsung phones) and I can't verify since the only AMOLED devices I own are pentile, but my Galaxy S3 Neo also has this "problem". Personally I wouldn't worry too much about it, since even with the glow the blacks are WAY deeper than any LCD display with a backlight can produce.

Thank God man.
I thought my phone is fake display.
Ur reply is proof that knowledge helps..
Btw just curious.. what are you?? How do you know this information not available in internet... So nice to see you man.
And regarding ur doubt, whether this happens in non pentile array amoled ...
NO.
I own a RGB amoled -Moto x ghost phone. It doesn't happen there.
I will check in moto x droid turbo . My cousin has it. So I will do and post results here.
And I wish to add this :
A 312 ppi RGB amoled (I have moto x ghost, 720p, 4.7 inch) is way better much much better than 440 ppi pentile amoled ( I have opx, full HD 5inch)
If I compare the images, they are much cleaner and sharper than opx . It's like the image has a depth, there is some stillness kind of feel. ...( I use colour control kcal, and so I test the displays in many settings not just default.
For example to make the images look similar as moto x ghost so that we can compare, I use rgb values as 32, 30, 27 value at 123, contrast at 121 and then slide the brightness slider to 3/4 or more.
Now both images look same in terms of how much dark areas are visible , the white wash noted in opx is now gone.
Now the images are ready for comparision.
Now the difference is the sharpness or clarity in rgb amoled. The feel difference i get is that there is depth in RGB. Its has a grip.
i got the huawei mate 10 pro specifically for the thin bezels and oled display with no rounded corners or rounded screen and i have to say i absolutely hate the display, it reminds me of the samsung galaxy 4 years ago, the colors are so dull that my Xperia xz1 has noticably crisper more vibrant colors putting them side by side makes the huawei look like a joke where like 50% of it's colors are reduced especially with green, is this due to the preapplied screen protector will there be a big difference if it was removed? frankly i am shocked at how bad this screen is to my Eyes i don't love the screen of the s9+ either most oled panels appear very warm to me i think the note 9 is the only panel that hasn't from the brief experience i had with it but the s9+ is still miles better, i have put the color to as cold as i possibly can but it still appears so warm and yellow, i have my Xperia xz1 set to the extra vibrant mode with blue set to 150 so i prefer cold colors over anything, but seriously the color is so dull on the huawei so dull and dissappointing, the Xperia uses ips the huawei uses oled, ips is not supposed to be crisper and more vibrant.
Uhh you do know there's a color profile option under Display--->Color option right? I suggest checking that out cuz this post is pretty ridiculous
Plus the XZ1 has an HDR display according to the spec sheets so you're comparison to crispness is basically out of whack
When viewing my S21 straight on colours are accurate but when viewing from an angle of about 30 degrees I have a strong blue tint.
I know AMOLED screens do get colour shift but this is stronger than I expected, do all S21s do this?

No issues on my S10 AMOLED display.
You can try to adjust colours in settings - display with several options. And there are color filters you can set in settings - accessibility - visibility enhancements.
Maybe it helps ... a little bit.
Hi all,
I would like to get some feedback on the AMOLED display quality in regards to uniformity when displaying a grey screen?
Did Samsung improve anything here or do the AMOLEDs still have clouding issues and the displays are not really uniform?
I have a Tab S3 and Tab S4 both with some clouding visible especially when displaying grey and dark grey.
Thanx in advance,
am
From what I have seen the AMOLED display on the SGTS7+ is actually pretty good for watching videos, the colors are excellent and so are the blacks.
It's an excellent display, as long as you use it over 30% brightness
As soon as you dive under 30%, it's a color-calibration sh**show, with a huge green tint issue (pretty much the same thing for any high-refresh rate displays of 2020. This issue was fixed by the following generation of displays, with the help of LTPO technonology)
I use it 5-6h per day as laptop replacement, and it's a blast during day time. But as soon as I want to watch movie at night time, the green tint forces me to push the brightness higher than my eyes wished.
The severity of the green tint will vary from one unit to another, but no one is spared.
