Has anybody noticed the following phenomenon? You look straight at the tablet while holding it perpendicular to the floor at your eyes level.
Then you start tilting it towards yourself - brightness fades at about 45 degree but then returns at about 70 degree and stays at the original level almost to 90. Same if you turn the tablet around.
I would not be surprised if the brightness was gradually fading as the angle increased, but this is the fact that it fades and comes back as the angle increases is what's puzzling me.
Not a big deal, I am just curious.

Color saturation is different when "the angle increases". I suggest you look into LCD polarizing filters. It's probably the screen component you want to investigate in order to understand this phenomenon.
Could it be the amount of light the ambient sensor is picking up? If you have it set to auto adjust that is.

I could not find that info related to tf700 screen... even generic articles on IPS and SIPS do not contain detailed description of how exactly brightness changes with viewing angle.

Nope, I have it on manual.
In case you have a tf700 - can you see this phenomenon, or it is just me?
I tried tilting while the screen showing a blank white page - same behavior, and it was almost like I could see some evenly distributed cloudy matter under the screen while at about 45 degree angle, and then the matter disappeared as the angle increased past 45...

OK, so I wrote Asus on it in get in reply usual "do a factory reset, if does not help - open an MRA";
I still insisted and got in reply something like "in this case we suggest you open an MRA".
I then visited a couple of stores and while I could not find TF700, I examined screens of TF101, TF201, TF300, Galaxy Tab 2, Acer, Toshiba - none had the issue.
At this point mine is going back to the seller.

HELP!
I returned my TF700 and got another one - and here we go, THE SAME issue - I tilt the screen - brightness fades at 45 degree then returns at 75 or so.
Dear FT700 owners, take a few seconds, share your experiences with me, I do not believe I am the only one having this issue.
ASUS folks, I would really appreciate if you chime on this too. If I return my second TF700 - I am done with ASUS tablets in general.
I went through blurry TF101, not working TF201, and now two TF700 seemingly having a display issue, and this is while the display is the main selling point of the unit.

My screen constantly adjusts brightness, but it has nothing to do with tilting the tablet. I can hold the tablet completely still and the brightness continuously adjusts, especially while watching videos. I must admit that it does get distracting as it happens every couple seconds depending on what is shown on the screen. I have autobrightness turned off.

That is the dynamic contrast that you are speaking of. Basically, the tablet increases and decreases the backlight depending on how much white is on the screen, etc... Annoying, but it also helps make the screen look good (super high contrast)... No way to disable it yet though...

What? Nothing is changing on the screen so it can't be what you are saying. If the screen is displaying STATIC content it should display the same brightness no matter how you are looking at it. As I said before in a previous post, it is manufacturing of the cheap screen. How else do you think Asus made the Infinity the same price as the Prime? They had to take shortcuts and use cheaper inferior parts. Sorry.
Saywhat? The poster that I was replying to said that it was most noticeble while watching videos, not while the screen was static... Of course it's not auto-contrast if the screen is static!
Please actually read the posts before making stupid remarks!

I use Vplayer and Diceplayer which have the gesture controls to max bright the screen and Volume control. When I'm watching a movie I set it to high and I never have an issue with it dimming. Try it out.
I think it overrights the light sensor.

So you are saying that you set the brightness to max and leave it there while watching a video?? I think that would be way to bright for most movie-viewing scenarios!

I also have a "brightness flicker" issue.
Even on a screen that does not change at all.
I just have to open google maps.
About every 2-10 seconds there are one or a few flickers.
I tried different power saving settings and disabled auto adjust brightness.
Screen still flicker.
I just have received my tf700t and have not yet noticed this flickering in other apps.
emmemm
this is normal, i noticed this too, when you go into a video it flickers and dims down but when you go back to the home screen it flickers back to normal, this is the contrast system not some bs about a cheap screen used by asus.

Is there any way to reduce screen brightness even lower than what we could do with built-in settings? Thanks.

I'd like to know this too, I have it at the lowest setting usually and it's still a little bright, I don't even need to turn it up outdoors.
On my modded galaxy s, the darky rom come with an app called "screen filter", it enable you to get your screen WAY dimmer, may be worth a look for in honeycomb, nice for froyo/gingerbread, you even have it in the task menu... my 0.02cents
I noticed that i always have to set it to the max cause it cut down on the glaze. This screen is like a mirror during the day.

try that app (requires root)
AdjBrightness doesn't work. I'm running Modaco ROM HR3, which means it's rooted, but AdjBrightness keeps saying it requires root. Thanks anyway.

Try "Brightness level" by curvefish. I can't guarantee it will work but it works on my g tablet?
Sent from my DROIDX using Tapatalk
I don't think any apps can make it dimmer, without rooting and system access. Brightness level widget doesnt make it any dimmer (it reports the brightness level as 8%, when the system brightness bar is all the way to the left, and when set to 0% in BLW the screen doesnt change).
One of the first things that I look for before buying any device is can the screen be set to a low enough brightness. Manufactures often overlook this in their quest to make screens as bright as possible, and in one case I ended up taping a piece of plastic over the screen of an Acer netbook as a filter to get the brightness down low enough to use in a dim room. In the case of the Transformer, I could not try before I bought, but the screen does go down pretty dim.
+1 for Screen Filter. I don't have a TF yet so I haven't tried it but it works great on my SGS and doesn't require root. I suspect it may not work as well on an LCD as on my SAMOLED screen on my phone since it doesn't actually reduce the backlight, but it's still worth a try.
Thanks, screen filter works!
Had my pad in my bag for work hanging off a chair.
Bag slides off chair and falls, maybe 2 feet to floor?
Now my transformer will not show anything on the screen. When I wake it, the screen lights up a pale black. It basically repsonds to waking it but there is nothing displayed on the screen.
I want to try and reset it but don't know how without waiting a few days until it dies.
Any suggestions?

That was the fastest, most trouble free customer support experience I've had in a damn long time.
Two thumbs up Asus.
They are sending shipping label and the pad will then be on its way to Asus support for anywhere from 5-14 days turn around time. (depending on availability of components)
good stuff, let us know how you get on.

This is a common issue with many transformers unfortunately after drops and knocks.
It is actually the data cable for the display coming loose, the back light is still on because the display is still powered, making the pale black of the screen. There is a guide somewhere on xda to take your TF and reconnect that specific cable. If you do not wish to take you TF apart I found hitting the back of the tablet (near the base where the connector is) it a flat palm can often knock the cable slightly back into place. This actually worked for me personally and it hasn't broken since.
Anybody else getting a washed out display at times? Almost like the contrast is too low and the whites are too bright? Seems to happen more on power save mode.
We already have a few threads on this. Switch to balanced or reboot.

I use it that way all the time. Doesn't go dim - as jrkart99 says - it goes too white and there's no contrast.
I know it's probably been addressed before but I was hoping for some kind of explanation to the lightbleed? on my TF700T. I question it because I ONLY notice it at the initial boot screen - when the "2nd" bootscreen comes (when the display dims), no bleed - Also, no bleed when on a black screen, watching movies, etc - nothing. Is the initial boot screen just set at an amazingly high backlight that absolutely any tablet (at least any TF700s) would experience this? Perhaps there is an alternate bootscreen I could install and test? I am rooted...
thanks for the advice
PS - I HIGHLY doubt anyone would return theirs for this
Do you mean the two spots on the right side, or do you mean bleeding out from other places? I have light bleed sometimes on the right side but it goes away after a minute or so. Like it has to "warm up" or something.
no, not really - at the initial boot screen, I notice it on all sides but mostly lower left around the "home" icons-when it appears - after the initial boot, it's pretty much gone - I am thinking that the boot up for some reason is set to such a ridiculously high brightness that 0 bleed (if it is even that) is impossible. Can you post a pic of yours during initial boot or a video?
I get lightbleed occasionally but it fades out after a few minuetes.

I think its normal.. my original prime had the light bleeds near home buttons too. I happened to have one of those from best buys first batch the sent in plastic no bubble wrap mailers so it had a dent on the box on the same side the light bleed was the strongest. But so far of the two inifinitys ive opened up at Best Buy, light bleed was in the exact same places.
The teardown from the Prime showed that it is caused by the screws holding the screen in being too tight. If you take it apart you can fix the light bleed spots by adjusting these screws.

I have the same lightbleed on a bottom of my screen (at 3-4 spots) going to the right side as well (1-2 spot). They all gone on the 2nd boot screen. Do you think that this will decrease the life of the screen?
Also I have notice something else and I really not sure what is causing this. I have setup brightness to about 30%, then If I start watching anything (Netfilx, YouTube or movie) my screen is start adjusting (change brightness up and down) like Auto Brightness options is checked, especially when it has a white (or very bright) background color. It is very annoying and very distracting for you eyes. Never happen on my Prime.
Does anyone have experienced the same problem? Any idea how to fix this are very much appreciated.

Regarding your second issue that is a known "feature" called Dynamic Contrast.
Quoting the All in one Infinity Guide stickied in the General Forum:

Yes,that is a "feature" called Dynamic Contrast but not all of us like it.Follow the directions from this post to disable but keep in mind that your device must be rooted.

I have what sounds like the exact same lightbleed locations. If I watch something late at night with all the lights off it is very apparent.
I don't think it decreases the life of the screen, my TF Prime had much less lightbleed, but it never expanded or anything.
So whilst playing around with the power settings, i noticed that when you set it to power saver setting, the screen does like 3-5 flickers, and you can clearly see the picture quality get worse. the colors get bad and everything doesnt look right. now this is not smart dimmer because im pretty sure this happens as soon as you hit the button and not when its just a dark scene or a movie.
try this for me someone, take a look at the screen in normal mode, then hit the power saver one and you will notice the screen slightly flicker and then you will notice the colors would go a little off or off contrast or something.
tell me im not crazy
Everything looks fine on mine.

You are not crazy. It definitely looks washed out or something, the contrast goes screwy. I've noticed that before. I turned off the auto dimming just because it was constantly going back and forth, but set it fairly low and keep it on normal mode. battery life is roughly the same. The screen is what chews up the battery life.
Yep, noticed it too. The contrast lowers and everything starts to look like you've been using a cheap detergent... Also, on power saving mode the light doesn't transition so much as walks the stairs with a bad leg. Very irritating when you have a live wallpaper that simulates a cloudy day scene and the brightness keeps flickering. Turned off auto brightness on day 1, so that's not it.

when using power saver mode, it actually adjusts the contrast of the display which is why it looks more washed out.
at the same time, contrast is improved when using high-performance mode.
so no, no one here is going crazy.

this is correct. its intentional. meant to save power in powersavings mode. if you rooted and have a overclock app installed, like ATP tweaks, that allows you to set the power modes, you can set balanced to 1ghz. it won't trigger the nvidia prism power savings. its only activated when pressing powersavings tab. of you set any other tab to 1ghz, your screen will look fine.
f.y.I. there's a tweak in Nexus7 forum, tegra3, that can disable smartdimmer feature also. smartdimmer isn't just lowering brightness either. you can disable smart dimmer manually or use the flashable zip. check nexus 7 forums for details.

Actually, yes, it *is* smartdimmer - trust me - if you don't believe me, go disable smartdimmer while in powersave mode - you'll see that the screen quality/brightness immediately goes back to what you are used to in Balanced/Performance mode...

Still the same. Iv'e been trying different color backgrounds/brightness levels/power modes and all I see is the screen flickering 2 or 3 times, just making it darker, not washing out the colors.
Just tried power save.
Blacks look a little washed out, not a massive difference here.
Turning on the IPS+ brings everything back contrast wise.
I have smartdummer disabled too.
I'll say essentially no real difference.
