Display brightness diagnostic apps for uneven brightness

hi forum,
switching from a MB, it seems that the brightness of the display on my MBP is kind of spotty (or not distributed evenly). i've read that it's quite common on the PB and MBP.
as much as i trust my naked eye, is there any apps to diagnose/verify this issue? will apple replace my MBP since it was purchased less than a week ago?
thanx in advance.

There is a program called LCDTest that has some gray screens in it under the Pixel test section. I think a full gray screen is one of the best ways to view non-uniformity.

Help, my iTouch 5 is stuck on the highest brightness, with option for auto-brightness. I've tried restoring, restarting and rebooting.

This burns battery way too fast, causes it to heat up fast, and is overall incredibly annoying.

The 5G iPod does not a Autobrightness. It does not have an ambient light sensor.
See if the following will allow you to adjust the brightness
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Uneven brightness in my macbook

I have a macbook with uneven brightness display. Strangely, the right quarter of the display is not as bright as the right. The unevenness is noticeable and I cannot bear it after a relative long time of work before it. I have tried with different brightness setting, no work.
I don't know how to solve this problem.
Two weeks ago, I have call the local apple service, they refused to replace the display for me. How can I solve this problem ?

Sorry... it resolved my uneven brightness problem. I was hoping it would do the same for you. Mine was actually dim in both lower corners but it is now perfect after doing the advanced calibrate.
Can you take it to an Apple store so you can "show" someone the problem? If not, I can see how this is going to be tough to get repaired over the phone.
Sorry, I hope someone else chimes in here with a suggestion.

I want to change the settings (brightness, contrast, gamma) for my internal cam on Macbook pro. I find having to but a third party software (iglasses, webcam settings) to control basic settings as unnecessary and exploitative. Does anyone have a solution?

I want to change the settings (brightness, contrast, gamma) for my internal cam on Macbook pro. I find having to but a third party software (iglasses, webcam settings) to control basic settings as unnecessary and exploitative. Does anyone have a solution?

It is not about payment of $19.95 (Igalsses) or $7.99(webcam settings). This is a very basic setting that should be available in the system settings. The automatic setting of the internal cam does not work great on low lighting as everyone is aware.
i am just amazed how users take in lying down and suggest solutions such as paying for a 3rd party paid app or improving the lighting in your room.

30" uneven brightness, shows as a dark band

Hi everyone,
I had a perfect 30" Cinema Display. Lately it started to show a dark horizontal band which starts at the middle left and extends to nearly 75% of the display's width. It's clearly the backlight which is causing this and after a while of use it normally gets a little brighter and therefore less noticable. This behaviour started only a few days ago and before that the backlight was relatively even.
Since it's only a few months old, it's still under warranty, but I know that the whole display will get exchanged for another (often not really "new") one. Mine has not a single dead or stuck pixel and I fear that if I take it to an Apple Dealer to get it exchanged, I might get one with even backlight but maybe dead pixels.
Is there any way to make sure to only get a replacement which has no dead pixels? Mine has none and I do not want to get a replacement that's not as good just because of my backlight issue...
Any help or ideas are appreciated!
Thanks
Björn
PowerBook G4 Mac OS X (10.4.3) 30" ACD

I have exactly this same problem.
I purchased ACD 30" from Apple.com (online) early December 2005. Only one dead pixel and backlighting was very even and no dancing green pixels. I use it with a PC (using the ATI Radeon 9600 Pro PC & Mac Edition).
Then, suddenly about a week ago, a dark area developed. It starts on the left of the screen, is about 3 inches tall, and then extends to the right a little over half the screen, gradually tapering off.
It's a fuzzy, darkish area, ie not with hard boundaries, but very noticeable (most of my windows have white backgrounds). It just looks like the area is dirty (yes I've tried washing it!).
The area starts quite dark and then gets somewhat lighter the longer the display is on, but never goes away, not even close.
I run the display at minimum brightness (I work in the dark!), but even when I turn it up to max brightness, the area gets brighter, but is still dimmer than the rest of the display (which is otherwise very even).
Is this just that the backlight has a certain area that's dim or partially burned out? Are there multiple backlights on this display? Or a single one (w/ spreaders) running along the left edge maybe?

HT1430 My new iPAD3 has uneven brightness on screen. Left half is brighter than right half. Any suggestions how to fix it?

My new iPAD has uneven brightness on screen. Left half is much brighter than right half. Any suggetions to fix it or shall I go for warranty replacement?

If restarting or rebooting doesn't resolve the issue and the device is new, I would contact Apple or wherever you bought the iPad, show it to them and if they can't figure out, ask for a replacement.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

Uneven brightness

I am using an image for floor in a 3D model. In the render you can see the repeating pattern of uneven brightness from 1 side to the other. Is there a technique that will even out the brightness across the image left to right or up and down. Thanks.

figured it out.
copy the image on top of itself.
add a adj layer - brightness
lower the brightness
add a gradient to a layer mask that revels only the right half.
viola.

My display starts "buzzing" when I increase brightness.

My display starts "buzzing" when I increase brightness, but gets lower decreasing lights. It seems to be originated in the left down corner on the back side.
It sounds like an electrical short circuit. Shall be needed assistance?

Actually, Apple says to use the Disk Utility program on the installed system to "Repair Permissions" as the program uses a database that is updated to the proper settings for the version of 10.6 that you are using.
The original DVD may have 10.6.0 on it but the computer may be running 10.6.2
The original DVD doesn't have any changes in the permissions that Apple has included with updates.
http://support.apple.com/kb/HT1452
There is also an Apple document that says that just about every warning you see in the window while doing the repairs should be ignored. I just uncheck the details box and wait for the "Permissions Repair Complete" statement to appear.
http://support.apple.com/kb/TS1448
I don't know if a permissions issue is causing the video settings issue, but it can't hurt to run the program.
Zapping The Pram is also a powerful reset mechanism you can try.

App for Calendar display on desktop

I'd like to see the Outlook 2010 calendar on my PC desktop, akin to an Android tablet widget. Desired view would maybe be the month overall with small text in the cells, and then a more detailed view at bottom for either the current day or the next
few scheduled appointments. Can someone recommend a good (preferably free) app for this functionality? Thanks!

Hi, This won't work even, as mentioned by Pedro even if we set the Defer Reqd. Enforcement property to YES, since there are couple more fields in the same record which are set to be Required TRUE. The reason behind this is the navigation is moved to a new block (Calendar block) hence Record level validation will fire and prompt to enter other required fields before displaying the calendar popup which are actually null.
Same holds good for IPSA solution, if we have just one Item in a record which is Mandatory then we can go with IPSA's solution.

Hi,
I want to display the demo calendar on a date field which is mandatory i.e., Required property is set to TRUE, also there are couple more items in the same record which are Mandatory as well.
My problem is when I press F9 for Calendar on the date field, it prompts me "Field must be entered", I came with alternate solution when the Required property is set to TRUE and value is NULL, I copy the SYSDATE to the current item before calling the calendar and when I press F9 it takes me to the next mandatory item in the record as the record validation fires.
Is there any way I can solve this problem?
Any help much appreciated.
Thanks in Advance,

Air Display app for Mac Air???

Will Air Display app for Mac enable me to use my Mac Air display on a larger, Windows monitor? Thanks.

Yes, but not the Mac app, the Windows app. Just buy the Windows version of the Air Display app from the Avatron web site: http://getairdisplay.com, and download the free Air Display video drivers for your Mac.
You can try the Windows app for free for up to an hour of connection before deciding whether or not to buy.
Cheers,

The Best Brightness and contrast for my monitor

I have an acer monitor AL2016W. I managed to get it too work but the screen is too bright. What is the best brightness and contrast for it? I have a resolution of 1850 x 1250, can I safely change that on my mac mini? Thank you for yuor help.

If you are using windows 8 - go to the start screen and just start typing Power.
When you start typing in, "Just Type" kicks in and starts searching for what you are typing, The default is to look for applications, but the power options you need are under settings.
So Click on Settings, and you'll see power options on the left.
Click Power Options and once you get to there, you should see a slider on the bottom of the window to change the brightness, I added a screen shot for you.
good luck

If the lyrics aren't in the ID3 tags (track info) they won't display.

15" C2D uneven brightness

So...
I've had the MBP since Monday and I've been noticing that there is some uneven brightness on the screen. There are two areas specifically: Right side (about 1cm along the edge) and bottom (about 2cm tall, about 4cm above the edge.) Both of these tend to fix themselves if I contort my viewing position, but at a normal viewing position (i.e. what I used with the old powerbook, I see the variations.)
Anyone else see something like this?

I Googled pixel size for Ipads and checked this size against the blury photos. They seem to be less than the max pixels allowed. Must be another solution????

Ged,
whilst generally I agree with you a question (or two) for clarification so we can be sure we're not comparing apples with oranges
I'm not familiar with O2's product lineup but given you're on Annex M is that a business package?
Are you on an Infinity residential or business package?
On the subject of the offshore support teams my experience from the other sife of the fence is that many, many of them are very technically orientated. The problem is that the ISPs they work for don't give them access to many of the tools that are needed (they need to raise internal requests to even get line checks done in some cases) and also they are very heavily scripted & monitored in what they do/say on a call.
Sounds like O2 are operating as a contact centre rather than as a call centre which is much more preferable from the customers point of view.
DISCLAIMER: although I work in the industry I do not work for BT and any opinions given are purely my own.
