can you guys try this out and tell me if you see this on your screens. first turn down the brightness and go to a web page with lots off black text. on my screen everything black leaves a faint line across the screen wherever there is a black pixel from right to left. do you guys see this? out is much less noticeable when the brightness is turned up.
I've seen a tiny hint of this in my screen, but it hasn't bothered me. If it's severe in your phone, you may want to contact HTC.

yes I notice this as well but I have to say that is only noticeable with backlight set to minimum, and i think it's a normal behaviour of an amoled screen. Now I have one question about the screen too:
When I'm watching pics or movies the screen has a very good resolution. For all the rest the screen seems a bit dotted and grainy, especially with text. For example in the app launcher where the app's names are written in white and the background is black the text is not extremely clear and if I take a closer look theres seems to be pink pixelss on the letter's edges. I can notice this thing almost evrywhere but I think it's a lot more clear to see with text and the backlight set to max. do you manage to see this too or do you think that's because i have a defective phone?

the grainyness on thin objects like text is 100% normal, its just how these OLED displays work.
This guy did some awesome research into the graininess issue using a macro lens on his camera. Really interesting stuff...

Eheh it's me that started that thread and i think that guy really did a great job trying to explain what's the problem... now i'm curious to know how many people notices this because till now it seemed that only me and that guy could see this "issue" so sometimes i'm still worried i have a faulty phone...it won't be a good thing since I'm from italy and getting a replacement phone wouldn't be very easy
My screen also appears reddish when i turn off the blacklighting in the clock app :\ maybe its defective?

No, mine experiences the same thing. Seems like reds are more biased when less power is given to the LEDs (not exactly a "backlight"). This is slightly noticeable on the lowest brightness setting too.
And mine experiences the "black line" issue too. I guess it's just how OLED screens work.

colors on NOVATEK are horribly wrong... I think they might be the AMOLED screens that HTC had originally announced the phone with... Then they noticed the color issue with the new AMOLED technologies and reverted to the EPSONs.

Neither Novatek or Epson make AMOLED panels (only Samsung and LG) and if it was an AMOLED screen it would be noticeably better

The new phones have nova panels last I checked so they didn't switch anything to epson. If anything they ran both as tests and picked nova for whatever reason.

Mine is Novatek and black levels are amazing. Color quality is good as well. I have seen Evos with the purple tint though. I just don't think it matters what screen type it is.

very interesting... i thought all novateks would have the hue discoloration... perhaps its something that will soon be hacked out... either way, im happy with my epson
I have a related question.
I actually have a 0003, with the Nova screen. Is there a difference between the 0002 and 0003 models with the Nova screen?
Tilde do you have a 002 nova?
My 003 nova looks quite good
Swyped from my Evo 4G
I like the vibrancy of the Novateks over the Epsons anytime. Whether there is a pinkish hue or not is only distinguishable when setting it side-by-side with another device as your eyes are constantly adjusting the white balance to the brightness color you see. Therefore, the hue goes unnoticed most of the time anyways.
BTW, both screens are definitely not AMOLED. I wish Novas were 'cause then I'd be using the red tone tweak and would be saving 42% of battery life as it's been tested with the Nexus Ones.
I have a google io 0002 novatec and have compared it to a 0003 novatec and mine is noticeably brighter and more vibrant than the other one at full brightness. i do detect a cooler color temperature but it's only noticeable in contrast with a screen with a warmer temp. who is to say either one is incorrect? they both appear color accurate individually
My cousin darrell told my other cousin darrell that my first cousin darrell that his face kinda red. Figured it was from being in the sun a little longer then he aught to have been in it. But to be honest wit cha i reckon i wouldn't have noticed if darrell hadn't said nuffin. Its a little red but ain't too red i reckon.
Its like that little ding in your car door. It's small until someone points it out to you. Then all of a sudden WOW it got bigger magically.
The Nova panels are fine. Flash some ROMs or read a book.

i was going to say the same thing.. now the samsung moment, the colors on that screen are all jacked up.. but thats for another section in the forums!
love my 0002 NOVA. the screen is stunning and no matter how much I try to find flaws in it , I can't
I have a Nova and an Epson on hand right now and i prefer the Nova to be honest. The colors seem richer and not washed out.
After hearing this news about the new screens coming to the nexus one it got me thinking. Will i be able to purchase an after market nexus one SLCD and install it on my "OLD" Nexus one, if not why?
We probably won't know until someone actually gets their hands on a Nexus with the SLCD and decides to disassemble it to make sure everything is the same to know if it's possible. But screen replacement is always pretty risky so unless you know what you're doing, I wouldn't try it anyways.
To me the question is why would you even want LCD over amoled. Amoled is better. They are only using LCD for lack of supply.
yeah i would never try doing that. i will get someone to do it for me and have them be responsible for any mistakes they make!
yeah i doubt anyone will tare down their N1 unless they break it...

but if there was a way to kinda provide a type filter on the screen that would help reduce the reflectiveness of the screen and not by Anti Glare, glare is not the problem its mainly reflections
Super-AMOLED displays are AMOLED displays with an integrated touch function..

Ah, ok, that makes more sense. I don't know if it would help at all as I haven't tried miself, but reflected light is mostly polarized, maybe getting light sunglasses with polarized lenses would improve readability?
I just tried that, it doesn't seem to work, what almost sort of worked was putting my sun glasses on the screen and that improved the visibility very considerably. I dont know the UV rating for my glasses but only down side is that my screen a tone darker with the phone set on "auto".

Hi,
I do have an issue with the screen of my SGN :
When the display is dimed at maximum and with grey backgrounds, horizontal lines like shades (in portrait mode) are visible.
It's almost like the screen were dirty.
Is it a special thing on amoled screens ?
Am I the only one with that ?
Thanks in advance for your reaction.
And sorry for my english, I'm french...

I have a SGN and I'm afraid I see the same thing. It's primarily on grey backgrounds...but sometimes is slightly visible on white backgrounds as well. Annoying....but the screen is otherwise brilliant. I suppose this is the price we have to pay...but I don't like it one bit ..
search the forum. There are threads about this and other display issues. You are far from being alone. I have sent mine back for this and other screen problems.

Yes, also present on the note... it is only viewable when you dim the screen and have a gray background. For example if you use the ScreenFilter app you can really see all the artifacts and lines. I don't really see this when you have full brightness.

Not got a replacement yet.
I've had two SGN's with these problems so far. The first one I ordered and the replacement I got. The first one I got even had dead pixels and dust behind the screen.
I don't think I will be getting a third one. Samsung really sucks at doing quality phones free from any defects. Just reading the threads about the SGN here on the forum shows that the screen is not the only problem. For an example, the physical buttons stops responding randomly and the note can't play some videos properly while other more older and cheaper phones can... I'm disappointed with these problems and I'm currently using my iPhone 4... Which works without any problem, but unfortunately doesn't have a 5.3" HD screen!!!!!
I have only seen 4 galaxy tab 7.7's so far and I noticed all 4 of them really have bad white levels as compared to my galaxy note, disabled the auto power saving and there is a difference in white levels but its still not even close to the galaxy note at the same brightness level. Even at brightness 25% on the note the vs 100% on the tab 7.7shows 'dimmer'whites. This is not a rant but I'm just asking if the screens are calibrated that way or should I keep looking?
Also I noticed that the mdine engine oon the tab provides oversharpening to a lot of my photos and its so obvious and makes the images look bd, supercurio has the same findings.
It is a pretty big screen so it may be they limited the brightnes to save battery power. While the claim is that OLED takes less power than LCD that is not always true. When displaying white, OLED tech uses like 4X as much power as LCD. The power saving comes in when displaying images with medium to darker colors.
What is the "mdine engine"? Is this something that can be bypassed by using a different picture viewing app?
It is amazing how Samsung seems to always add some crappy image "enhancement" like DnIE or such crap. Why can't they just leave our images alone, as we meant them to be? It is freakin' OLED man. You don't need any contrast or sharpness enhancement you knuckleheads! OLED by nature is sharp and has great contrast! Duh!
I don't know. My 7.7 is super bright, sharp and with way warmer colors than my Note.

I'm thinking the samr thing that samsung might ne limiting how bright the whites can go duebto the screen size but based on what I've seen on samoleds some screens juat put out better white levels, not really brighter but whiter.
For the mdine its running system wide.

The samoled plus tends to have more warmer colors than the samoled, is the whites on your tab 7.7 'whiter' than on the note at the same brightness level?

Yes I believe so, Supercurio knows more about that stuff.
EDIT:
simulated example done in photoshop, anyone with the tab7.7 and better photoshop skills feel free to redo this simulated image
Perhaps one of the other reason that the 7.7's screen isn't quite as bright, apart from the obvious power saving reasons, is an effort to possibly reduce the OLED degradation (burn-in) effect.
Either way, although I certainly noticed out of the box that my 7.7 wasn't as bright as my Note (or even my GS2 for that matter!), I was never really bothered by it because (especially when you use movie mode) the colour reproduction is very accurate, and paired up with the contrast levels, it's still fantastic!
I guess, to me, white doesn't necessarily mean I need to put on a pair of sunglasses while looking at my screen lol!
I just wanted to know if the norm has lower white levels, what bothers me more is added sharpening on some images.

Yellowish? Not at all! At least not with my unit anyway. Sure it makes the screen generally warmer in colour, but IMO, more than anything, it makes the colours look more accurate and natural.

Well ever since the Galaxy S changing the color mode to movie mode gives a yellowish cast, this is probably dependent on the calibration on the screen we get in the first place. I saw a friend's Tab7.7 the other day and his white levels were really brighter than my Galaxy Note. FWIW, its still a luck of the draw when it comes to color calibration on the screen. But thanks for that tip, when I'll purchase the Tab I'll make sure to also check out movie mode and see if it hits my requirements.

Very bright noticed the same with the Note ,
Nexus was somewhat easier on the eyes at night,
But probably like you I like a very dim screen at night.
When the brightness is turned all the way down on the 7.7,
is any banding or other issues seen like many report on the Note?
Blacks are black I'm sure but how are greys that are near black.
On the Nexus they were fine, but on the Notes I seen they could have been darker?
