[Q] black clipping in note 10.1 ?

hello guys
i want to buy android tablet soon & i like the note 10.1 very much
so i want to ask u
does the note 10.1 have black clipping issues like galaxy s3 ?
& is it software or hardware related ?
Below is a attachment of test pattern, you have to download and view the image within note gallery, preferably in a dark room, and at maximum brightness. if you can see the left bar boxes 10 to 1 with little to no gradual gradient then most likely note has the black crush issue
if someone can post screenshots of this 4 images on his tab
thanks

So many views yet not one reply

I'm not sure if I have a problem or not lol

I see the numbered gradient bar in all four pictures. They look the same on my Note 10.1 as they do on the external LCD connected to PC. I think black clipping just affected the original Note OLED. Note 10.1 is PLS LCD. Looks fine on my Note II too.

[Q] yellow/orange color problem

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.

Galaxy s6 edge screen issue

My Galaxy s6 edge has an issue displaying video. Everything looks good but whenever it shows night scene or really dark scenes there's black blotches on the screen that makes the picture quality look 8 bit or it looks like it's watercolor. I was wondering if it's normal or a issue with my display. There's a video on YouTube called The Dark Knight The Joker's Last Scene where i can really see the effect. It's especially noticeable when I watch it in a completely dark room at night.

Maybe a defective screen. Bring your S6 back to Samsung for warranty repair.

Vivo NEX display light bleed issue.

Hey Guys, while I was watching something on the Netflix last night, spotted some hazy areas on the NEX and when I cross checked the same video on my Note 8, it was just fine on the Note 8. So, it was a pretty bad light leak on the NEX. I have put up a video of the same on the link below. check it out and also uploading an image of the same. Please let me know if anyone of you have this issue.

To spot it, go to a dark room and download a dark grey image and view it in the full screen at full brightness. Also attaching the image that i used for testing.

Well it’s not only note 8 but also presented at Galaxy s8/s9 series.
I’ve noticed too at my S9 plus unit that got earlier April.
Simple you’ve got used and live to that as there’s no other solution even getting replacement device or replace screen there’s no warranty will be free of that kind of issues.
There’s details review from Anandtech to that issue presented as I said Galaxy S9 series.
Take a look over here as I assume Vivo Nex also using AMOLED display from Samsung.
Only my OP5T does not show that issue with dark scenes at low light level brightness.

Well im just saying with above post that's those issue are common with AMOLED panel.
You can try your luck by replacement either whole device with new one or go service and being replaced by new panel
But as i said there is no warranty new device or panel will not have the same issue:fingers-crossed:
It's your personal choise what going to do

That's a shame. Because, I have had the note 8 for the last 9 months and luckily have had no issues. And I yeah I don't think the replacement is going to help, but just giving it a try and hoping I get a good panel

My Vivo NEX viewing angle not Good. If I see the screen straight (90*) screen looking something yellowish if I change the viewing angle a little it became cool white. Is it screen problem or display

Viewing angles on my phone looks pretty good. Yes there will be a slight shift of colour, but that happens on all the phones. So, I don't think it should be an issue unless its really bad on yours.

I just tried your posted image I didn't notice any bleed. Sucks you must have gotten a bad panel. GL on the replacement let us know how it goes.

I got the replacement from Amazon and the new one seems fine

Yellow tint at the bottom half of the display

Hello everyone!
Did anyone notice this ugly yellow tint at the bottom of the screen? It about 1/4 of display along from camera side. Could anybody prove that the problem could be fixed by update? I have MIUI 9.5.16.0 ODGRUFA on my phone, official Russian rom.

Put screen contrast to Increased contrast not atuomatic.
If there's till problem maybe your screen has problems.

I have already put the contrast to Increased. It has a little effect, but I steel see the warm tint at the bottom. It visible only on a white background and none-visible on any others colors (tested with Screen Test app). This not interrupting with using the phone and could be ignored, but my old Redmi Note 3 Pro has the clear white color and I don't understand how the top-phone like Mix 2s could has a defect like this.
I have created the same thread on the MIUI official forum and as I see this is the mass global problem, but not everyone notices the yellow tint. Many of users are talking about the same on the Russian forums (4pda, for example) .

install aida64 app and check whether its a 1080p jdi video panel
if yes then its a hardware panel calibration issue and u must try replacement as same happened with me on mi mix 2 in which i had 1/4 upper part red tint and this problem cant be solved by any software update and in worst case u can adjust its calibration by flashing a custom kernel which support kcal color profile but that will only reduce that tint and not completely eliminate it

As far as I know, there are only JDI panels. I did not find more than that when I searched the internet (which just criticized them for their low quality and the bad choice that Xiaomi made with these)

Yes, here is JDI, the only one panel in all Mix 2s smartphones.
