yes that is true on all n9's as far as I know. This is characteristic of the Pentile Amoled display. Are you seeing the purple tint though?

A: Oh, crap, now I looked at you photo. No, that should not be happening to my knowledge. I'll take a look tomorrow on your example case on both displays we are shipping with (we had plenty of versions of the displays during the making on N9, some times to the better, some times to the worse)

So it looks like someone is at least looking into it.

Please say so!

He might be used to zooming in on portret mode text and not notice the ugly phenomenon.

Since I first noticed the lines, I've now started noticing them everywhere, where there's something dark next to something light. Even just opening the vkbd in apps with white background in landscape view I see the lines fill the area above the vkbd.

Where is Konttori posting follow up to this, about his findings on testing displays?

So while I still have to see a working screen on the N9, I now know the problems aren't always as evident as on my device. This may explain why some here do see them, but wonder what the fuzz is all about. :)

(I was afraid I might have ruined his fun with the phone, but he'd already decided to sell it and go back to Symbian, anyway :) ...)

I'm also seeing the stripes. They show up in both portrait and landscape, but they are much easier to see in landscape. It looks like there is a "invisible line" that bleeds everything that's on the line through the screen (upwards when in landscape, in portrait it's to the right).
So there might be just white on the invisible line and there's no stripes on the screen. But when black text hits the line, the black bleeds through the whole screen.
Here's a oh, so wonderfull paint illustration... :D

It's really hard to get proper photos of it, because it's not that bad, and when trying to get photos you actually need to make them bit blurry or the lines disappear into the moire noise.

I got my N9 on Saturday and noticed the pink fringing on white text and the left edge of a white panel straight away. Sadly that seems to be an issue with pentile AMOLED displays just not being as good as RGB panels. It reminds me of Windows text anti-aliasing. I stare at Mac screens most of the time with occasional switches to Windows so I notice these things. I would hope it could be tweaked though. MacOS on the same panels doesn't have the same issues Windows has so it can be alleviated with software obviously. To me it just looks like the sub-pixel rendering algorithms need a bit of a tweak.

The black spots on dark grey screens I noticed last night watching a video in a dark room and then discovered this thread. I've got a black line about 4mm wide stretching about 2/3rds of the way over the screen about where the volume buttons are. I've got two parallel lines about 4mm wide and 2cm long in the middle of the screen toward the right edge. I've got another blotch near the bottom left of the screen. I only notice these when displaying something dark grey in the dark. I was playing Tron (the movie) on it so you can imagine how distracting dark splotches are on a mostly dark grey movie. (As an aside, the movie player skips frames all over the place on movie files that worked great on my C7 - hope they can get a better performing codec sorted)

The black spot issue is obviously a manufacturing issue and it's very, very disappointing. I don't notice it 99% of the time but I know it's there. When it's such a beautiful and expensive slab of technology, little flaws are not acceptable. If I wasn't enjoying the phone so much otherwise I'd send it back. I figure I'd give it a while to see if Nokia responds to this issue and fixes it in a later production run. Seems pointless getting a replacement just now if it comes from the same production run. Surely they're going to have the same issues with the Lumia 800 which shares a similar screen?

The automatic screen brightness adjustment also seems to have a life of it's own. I hope that's fixable in software also because it does ramp up and down a bit too aggressively.

Love the phone and OS but I'm somewhat disappointed by the screen.

Does anyone have this problem?

http://img231.imageshack.us/img231/2826/blackspots.jpg

Apologies for the picture quality, but in person it's very noticable. There are also black patches scattered on the lower part of the screen. They are not dead pixels. Rather like 'after burn' effect on a plasma screen. Or a soot in the screen. Those two black lines are also manifested during the phone's boot up just beside the Nokia logo.

Kindly check your screen if anything like this happens. You must be in a dark room and using the camera function. I forgot to set the screen brightness to full, but I think it will manifest more. The issue will never show up when you're in a perfectly lit area.

I think Nokia should be informed about this issue.

I'm waiting for a new unit replacement.

I have a 64GB device. Anyone with 16GB seeing the issue?

I quickly tested a blue model at a store and it had the same issues with the reddish/green lines. So 16GB devices have the same issues as well.

My 64GB model just came back from the repair shop and they apparently swapped the display to a new one. However, this didn't improve matters as the issue with the lines still exists. The display actually seems to be slightly worse since the red tint on left side of the display, when it is positioned vertically, is now much more noticeable than with the old display.

I got it from a Finnish cellphone store called Elisa Shopit and it's made in Finland. I don't think that really matters though since I believe that they use the same components everywhere and in every N9 model.

Another weird thing with this device is that when I opened it and started it up, the default pics/videos were all missing. The box was sealed and everything. But to have those exact same spots you are is kinda of weird to me.

Also this one doesn't have a dark pink hue/tint on the side. There is a slight tint. Better than the previous one I had.

Therefore, my assumption was that, because of this, when the n9 is in darker environments, this purple or pink over-saturation is still there.

Apparently, in the PR 1.1 release of the N9, Konttorri claims the following:
"Color management is less nervous than before (neutral sRGB space color palette is now used always, except in clearly outdoor situations, when oversaturation is applied to adjust how eye desaturates content in brightness)."

Let's hope that this is what I and others in this forum have been experiencing and gets fixed! :)
Lol!!, I'm still a bit confused as I also could be interpreting my issues completely different than those voiced by Konttorri.

Oled is still in it's baby steps and this kind of issues are not totally surprising.

AFAIK despite being marketed as an AMOLED CBD, the N9 is a SAMOLED (pentile) + Nokia twks.
And yet jakiman's Samsung Omnia 7 (SAMOLED pentile) doesn't have the 2nd issue listed in his post?

(if the LG ones don't have this pink bleeding)

I didn't worry about it, because I had the same already in my N8, so I just think it is a common AMOLED issue (screen bleeding, or however you want to call it)...

Therefore it doesn't bother me, because it's only visible to me in rare conditions (using the phone in pitch black night, which is really seldom for me).

And it is also certain that it doesnt matter what model you get, 16 or 64GB, the culprit is the Pentile Matrix screens used in these devices. There are some who get lucky with less tint and some unlucky people get annoying tint, black spots, and whatever other display issues that have come up in this op. :mad:

Unfortunately, getting a replacement is like taking a gamble on whether your replaced device will be better or worse.
