Hi there,
I just got my touchpad 16gb and on boot (dark) my screen looks like this:
Is this normal on touchpad or should I send it back.
Thanks for your opinions!

It's an IPS display pannel screen, which are known for being super bright and having light bleed on blacks. However, they also have the best color gamut (range) and quality. Apple uses them for all of their displays (including the ipad). You could turn down the brightness a bit if it bothers you.
Mine had the same issue

What do you mean by had? Did you send it in for repairs or did you cope?
Thanks.

If I were you I'd definitely send it back while you still can and claim one of the 100,000 - 200,000 HP is going to produce next month. Mine has a slight cloudyness / gohsting effect like yours but is barely noticeable even on max brightness on a black screen. These Touchpads have been know to have screen defects due to improper installation or settling in during production. So if it were me I'd send it in for repair. Sorry you just got it and will end up missing it while its away I feel your pain. Hope I could help.
To fix the issue...
Go to setting and slide down the BRIGHTNESS...
Hope to solve your screen issue.
Mine looks identical to yours. Though I don't notice it very often in normal use.reminds me of my old g2x screen (also ips). I guess just live with it.

Mine looks similar. Luckily it's only really noticeable as the device boots.

backlight clouding
my touchpad got the same issue, seems to be normal, sadly
Add another one to the list.
All 3 touchpads I purchased exhibit similar backlight bleeding--all along the same left side, near the speakers.
1 was about as severe as the attached picture in the OP. The others minimal.
My guess is faulty design in tandem with the IPS technology resulting in what seems to be widespread--aka normal.
Yeah, i notice it on my normal desktop IPS monitors as well, but mostly if you have brightness way up and a full black screen. IPS has a drawback that it does not display true black very well. I keep my normal monitors at like 30-40% brightness (much higher and I would go blind from it) and I don't really notice it.
All are the same
Have seen 6 of them plus mine...same issues.
Deal with it at 99... whe ask perfection for a tablet at the price of the photo frame. HP should return your money and donate the tablet to a poor kid in the third world. They will save some money in that case...
If less means "more" than "all" will be nothing!
Yeah my Asus Transformer IPS panel also had light bleed. It the IPS panels are excellent screens, but this is one of the prices you pay. Besides during normal use you don't really notice it.
I advise not staring at your screen while it's booting up.
Got my TP back from the European Service Center (located in Hungary) today.
Well, the bleeding on the left edge of the screen got slightly better BUT the operation left visible marks on the housing.
It seems they pried the Touchpad open with some sort of tool around in the area of the rubber seal surrounding the display, thus leaving "screwdriver-marks".
I will contact HP Support again.
Should have listened to you IPS Panel guys
I really hope i got a defective unit. This thing is completely washed out. Same app s running side by side with my first gen it looks like the brightness is way up and the contrast is off. Ive tried every setting possible. Anyone else ?
Also it seems to b e registering a constant touch on the screen. It goes into select mode as im typing

Sounds defective. My display could not be nicer and i have a bit of an obsession with screens. Can you post some pics or an hd video?

Pictures? My screen, as far as contrast and brightness is concerned, looks good.
Nevermind. Looked at it closer, their is significant ghoasting of the keyboard. Its a dud

I agree, mine is great.
Well I hoped that Asus after TF101 realized that the have to improve the build quality of their tablets. Imagine my madness when I discovered my new Prime is creaking...!!!
A little below of Top left corner of prime. God.....
TF101 was creaking but I never would thought that TF201 will be creaking too!
I thought it will be as good made as Ipad....
Well Asus - this is the last tablet I have bought from you...
Also got a question about the screen. Some times I can sense and see that despite of auto brightness off that the screen adjusts its brightness by itself. It is a little change but my sharp eyes can see this...
Do you have a similar thing?
Contrast changes dynamically when set to power saving mode.
TF201 / XDA premium
Yes I know. But I use all modes and feel the same that sometimes the screen changes a little the brightnes.
my prime seems pretty solid. maybe the glue on your glass panel needs to still set more. Man, Asus has really came up with hit or misses on a tablet being flawed or not. this is a great device though. at the area where you said you hear creaking, does it look like the panel is not flush there? where did you buy it from? you can always exchange it. I know some don't like having to send it off n wait for another one. hearing some of these panel or touchscreen issues be making me check mines on the spot. luckily mines don't show those symptoms.
Yes the brightness changes based on the lighting of the area at the time; it's called auto-adjusting. That is normal and I like that.
Mine is loose and not flush with the device on the bottom right but it is not a huge deal to me

If you push in on the glass in this spot does your volume rocker move?
no it does not
That sucks man. I would be really annoyed if i had a creak in my prime. I have to wonder if they rushed through fixing the wifi issues and damaged some of the primes while in the process. I have seen all of the pics with the scratched bezels that look like the techs were using a flat-head screwdriver to pry these things apart. I'm not sure if mine never went for repair or if the tech that did mine just had the right tools and skills but it seems to be a perfect specimen physically at least. I would love to read an inside account of this product release.

The brightness changes when using this app huh? When u touch the screen to scroll it quickly brightens then goes to normal? It seems like the xda app not the prime
Modded by MBOK
I have an HTC G2, and whenever I touch the screen on a lighter background it changes the tone of the background to a pinkish color. It does it in XDA app as well as web browser, almost anything with a white-ish background. Sounds similar to what your experiencing, it only happens when you touch the screen, right?
the problem with the self adjusting brightness accurs while playing or watching youtube. It doesnt matter if am toutching screen or using dock keybord or just a mouse. I do not know if it is on purpose.
Did you notice the same issue?

I do. None of the other issues but noticed this brightness geekin out with the xda app
Ugh. Mine starting creaking today. It is like the left hand side of the screen has separated something. The right side feels solid. The left has flex to it - like the glass gives ever so slightly, resulting in a very annoying 'click'.
This really sucks, because otherwise the device is fine (no stuck pixels, wifi and GPS works). Guess I'll wait a week or so for Best Buy to get some local stock before taking it in for exchange.

I noticed that my xda app and all Tapatalk apps change brightness for some reason when pressing things I went into the settings on the app and changed the theme to dark works great now. I I also get a creak where my volume rocker is which is cool with me I figure its just because the gap where the rocker is I just don't press it

My TF101 had this and my TF201 does wiggle a bit in the top left. It makes sense with the volume controls there.
I`m very happy with my prime, and apart from the gps it seems to be without faults. But the auto contrast is really annoying. I get why it`s on in powersaving mode, but it is still there, even in performance mode. Is there any way to turn it off? I hope this can be brought to Asus`s attention.

This might be what you seeing at work. Its a new innovative technology from nvidia implented in tegra3 for further battery savings. They have another feature they added also but can't find the description on it.
" NVIDIA PRISM Display Technology - PRISM (or Pixel Rendering Intensity and Saturation Management) reduces a mobile device’s backlight power while simultaneously enhancing the pixel color to deliver the same visual quality with substantially extended battery life."
I have never had an issue like you describe... anyone else? Is it happening more in bright situations or what?
I don't have anything like this. Do you have auto brightness turned on? Could it be tied to that?
Sent from my Transformer Prime TF201 using Tapatalk
Get out of powersave mode.
I have noticed this too. On several occasions I have noticed the screen getting brighter or dimmer for no reason. I have checked and the Auto Brightness IS off. It doesn't happen all the time but I have noticed it.
I have auto brightness turned off, and I sometimes get this problem while watching certain YouTube videos. I can't think of any specific ones off hand. It's pretty annoying. I always run in balanced mode.
Same problem here.
A really simple way to see that, is set the contrast to the minimal (like when in bed ) and watch any video the luminosity will flicker a lot.
It seems that starting from 25% luminosity this effect is way less visible (even if still here).
Hmm... I've always had auto-brightness off and the display has never changed on its own.
But I usually have the brightness very low, and this may be my inability to notice these kinds of things.
Just did some testing, it's less visible when the brightness is turned up a bit, but still there. But I tried a regular movie, and I didn't notice it, but it was very obvious when watching anime. It happens in every power mode. I guess I can live with it if it's only visible when watching anime though...

I think you are talking about Tegra 3 DIDIM tecnology
and it can't be disabled on TFP
yeh, I guess that's it. I wish they would implement a way to have it disabled in performance mode at least.
Sent from my Transformer Prime TF201 using xda premium
I wonder if it's hardware related or software/driver related. Hopefully in future rom developers find a way how to disable it because it's really really annoying.
The best way to see it is to turn your brightness all the way down, go into a dark room, and play a YouTube video. You'll definitely see the contrast/brightness changing.
Sent from my ROOTED Transformer Prime
The above describes this issue perfectly. All the resets in the world will not fix it, I'm afraid. This is a "feature" of the Tegra 3 chip to increase battery life. I have been experimenting with this extensively. You will notice this much more when brightness is set low (in my case, below 20% or so). It is especially evident in large white or light grey areas of the screen. You will notice what looks like automatic readjustments of the brightness of these areas. It will appear as though the screen is the automatically increasing and decreasing brightness - and the effect is by no means subtle. Try watching a video where there is a lot of white sky. Have a look at this video:
Search for Youtube Video "St Patrick Swipe" if you wish. Set your brightness at about 10%, with auto brightness off. Ensure you are in Balanced power mode or Performance power mode (the effect is very evident in Powersave mode if you want to try that, but I guess that is to be expected). Switch the video to full screen and go to point 1:53 and watch as the two guys go through the gate and up the hill (until about 2:12). You should see the video darken and lighten noticeable (thanks to the good old grey Irish sky!).
For me, this is a show stopper. It means I cannot watch videos at lower brightness levels, when the effect is more noticeable. It also means that when browsing web pages (which have white backgrounds), I am constantly seeing this contrast readjustment and it is very annoying and distracting. I really wish I was the kind of person who notice this kind of thing, as I'm sure quite a few may not. I am returning this otherwise fantastic tablet because of it.
Yes, I know this is my first post and will probably be deleted (you guys are strict!), but I've been reading about this problem here (there are plenty of threads) and in other forums and just wanted to add my voice.
I noticed this the other day whilst watching this YouTube vid in bed with the brightnes low.
http://www.youtube.com/watch?v=uMm9E8pGZ7M&feature=youtube_gdata_player
It'd be a little better if it was a subtle change, bithgening ad dimmming slowly rather than the abrupt increase/decrease in brightness. It'd be even better if it could be disabled altogether but at least I know it's not a fault with the TP and is in fact a feature.
Thanks for putting my mind at rest everyone, I'll live with the annoyance.
I also really wish this could be disabled. It is very very noticeable when watching anime. Keeps changing from bright and vibrant to dark and dull

Just a quick heads-up: In the Acer Iconia A510, also a Tegra3 tablet, this issue does NOT occur.
So it's not a hardware thing and Asus needs to fix this
Could the problem be the proximity of the light sensor near the screen? Maybe it's bleeding light into the sensor.
i myself is having this issue, and i see it constantly cause it affects my eyes alot, my eyes feel like its re adjusting to the dark and brighter setting when it happens so i notice it instantly, i really do wish that it would stop, cause its hurt my eyes at night when the screen gets brighter, i think its affected by whats being displayed on the screen, if something is really too bright, it dims it and if something is too dark it brightens it but for gaming and viewing movies that can get very annoying since movies and gaming changes scene very often.

Does anyone have both the TF 101 and the prime? I had gotten a replacement from Asus, and I noticed the screen would wash out a lot more on an angle compared to my TF 101, So asus replaced it (the first replacement was a C30 and they replaced it with a C20 which actually has better wifi range than the C30 did) And I noticed again that the screen would wash out more when held on an angle than the TF 101 did. Now I dont think I got two primes with the same exact issue so now I'm thinking that maybe its just the way the TFP LCD panel is. So I was wondering if someone that has both a TF101 and a Prime if they can do a side by side and let me know. Put the same wallpaper on both devices, and also set the brightness to the same on both devices(I set them both to max, with IPS+ off on the prime). Does the prime get more washed out when held on an angle compared to the TF101?
Thanks in advance
Put the Prime in Performance Mode and then re-do your testing.
Its an auto contrast feature of the tegra 3. Seems to happen more in lower power modes. Search for contrast on this forum there posts about it but its a feature not a bug. Higher brightness and super ips mode are also ways to reduce it from happening.
Oh yea and the 101 didnt have this feature.

Thanks, I was looking at that but wasnt sure if it was the same issue. I do notice the TFP washes out a lot more on an angle even when in performance mode. Since I got two replacements that were like this I'm thinking more its just the way it was made. When asus sent me the first replacement and I noticed it(I dont think I noticed it on my original TFP) I took a video of it washing out more compared to the tf101 when viewed on an angle. I'm pretty disappointed.. I have never seen an IPS screen wash out like that. It washes out on an angle more than my HTC Evo View(flyer) and that's not even an ips or slcd screen
Here are the links of the videos of the first replacement they sent me. This new replacement washes out the same way on an angle

I have both, and don't notice any difference except the 201's screen is much sharper and way brighter. I hack the 101 with revolver, and have left the 201 stock. Just got the GPS kit, and now get more sats with the 201 indoors! Too bad the GPS kit doesn't have a power jack. My 201 is a BCOKAS.
If those videos are accurately showing what you're seeing with the device in-person, then I would exchange the unit again. Mine looks nothing like that. Like others have said, the viewing angles on my TF201 are just as good as on my TF101. I'd say the Prime's screen is an improvement in every way, and I thought the original Transformer had a very nice screen.
What you are seeing is Light Bleed, you can search in XDA how to fix it yourself (you have to open your Prime) or return it to Asus. That is not how the screen should look.

Yeah, thats the way it looks in person. I really doubt asus will replace it a 3rd time... I'm waiting to hear back from Hai Trat. I expected the viewing angles to be the same as well. when I wish I could remember if my first unit washed out.. I think I was too anal about the dead pixels it had to notice if that one washed out. But after getting the 1st replacement and the 2nd and both washed out like that and both were different batches (first replacement was a C3, 2nd was a C2) I figured maybe it was normal. Guess not..

Nope, it's not light bleed. That unit does have some but the video shows it correctly, when viewed on an angle the whole screen clouds and washes out. And this is the 2nd one that has done this. My tf101 has some light bleed and doesnt do that at all. This 2nd replacement I have (the video is of the 1st one) the backlight bleeding isnt as bad and it still washes out like that on an angle.
Hmmm....Now that I do a direct side-by-side...in a dark room, with dark backgrounds on both tablets...I do see more of that "glow" that you're showing in your videos. The image is still crisp, but there is a distinct white-out, glow kinda thing going on. Maybe not quite as pronounced as your video, but that could just be lighting, camera, etc.
I probably wouldn't have noticed without doing the side by side video to see if I could show you how mine was OK, lol. LIke I said, the image and colors are still crisp, but there is a bit of that glow over the image.
I almost wonder if it isn't the oleophobic coating refracting the light. It's definitely not just general backlight bleed. My Galaxy Nexus (which also has an oleophobic coating of some kind) doesn't seem to exhibit the same off-axis behavior, but the screen is OLED, is much smaller, etc, so it's hard to make a direct comparison.
Your videos did seem pretty pronounced though. At this point I can't comfortably say one way or the other. I still think my screen looks great. I guess you just have to figure out if you're satisfied or not. In comparison to my TF101, I'd pick my Prime's screen every time.
