Cleaner behind display - brighter areas

I sprayed some cleaner (glass) on my Powerbook monitor and now I have lighter patches on my screen.
I think I got cleaner behind the screen. Will this eventually dry off, or is it something to majorly worry about?

Hi Kudos,
Spraying cleaner on the outside surface of the monitor shouldn't allow it to seep inside. However, Apple does not recommend using standard glass cleaning solutions on their TFT screens. Always use a specialised cleaning solution like iClean.
Try getting rid of the patches by rubbing the affected areas with a damp cloth. If that does not get rid of it, or if it is clear that the solution really did seep into the display itself, I'm afraid you've caused damage to the monitor which in theory is not covered by Apple Care.
Good luck!

The display brightness on my macbook pro is not working

I just bought a macbook pro in June and the display brightness keys are not working, nor is there a scale I can find in the system preferences to adjust the lighting level across the screen. Why is that and how do I fix it?

Go to System Preferences>Displays. You can adjust brightness there. Also make sure that the "Use all F1, F2, etc. keys as function keys" are unchecked in the Keyboard preferences.

Dimming Display Brightness to Zero

Hello All,
I have been having a problem with the display brightness adjustment for a long time. Basically, the display of my 17" 1GHz G4 cannot be dimmed to black. From the System Preferences the display brightness can be lowered with the slider. In the final third however dragging the slider further to the left not only does not reduce the brightness it actually slightly increase it, and the display start to flicker.
Any ideas what could be the cause?

That model doesn't support dimming the display brightness to zero, except through Energy Saver (which may not work with all third party USB devices), or a screen saver that has a picture that shows nothing but black. Some third party hacks dim the display, but they are not necessarily that reliable.
Only Apple's notebook displays dim to full black.

MacBook display brightness will not adjust

My MacBook display brightness is very low level, the F1 and F2 brightness keys bring up the transparent window and show brightness turned all the way down, but F2 does not increase the brightness. In Preferences, the display section shows the Brightness slider all the way to the top, and if I attempt to slide that down it snaps back to the top, and the actual screen brightness does not change from very low. I also have verified that the function keys are NOT set to lock out the brightness function, so pressing command and F1/F2 does nothing. So nothing from previous forums seems to apply! All other function keys operate properly (multi-window, volume, dashboard).

OK guys, think I found a solution to this one.
My girlfriend's mac had the same problem as yours, and I was motivated to fix it becuase I needed to use my mac for my dissertation and she kept stealing it!
anyway, turn the brightness all the way down, press it up once and you will see the screen flash. do it again, really fast up and down up and down and the scree will stay on as long as you keep playing with the buttons.
next, use this temporary fix to get into system preferences -> displays... and change the resolution to something considerably lower. then it stays on permanently. Not too sure about why this happens, maybe the mac can no longer handle that many colours or complexities?
sod it. enjoy.

What is the best way to clean the display on an rMBP and Thunderbolt display?

Can I use a damp cloth to clean my display on an rMBP and a Thunderbolt display, or should it be a dry soft cloth? My displays are in desparate need of cleaning.

This is what I now use:
http://www.officeworld.com/Worlds-Biggest-Selection/DRACB702288/13Q1/?gclid=COjp r8rOj7kCFVNo7Aode3EAxg
I discovered it in the supermarket. I dampen a small microfiber cloth (6x6) with the Windex and wipe the display. Then I use a large microfiber cloth (12x15) to dry it. Excellent results.
NOTE THIS IS NOT THE CONVETIONAL WINDEX CLEANER.
Ciao.

Which cleaning product to clean behind the glossy panel?

Hello. I have the gradient issue again but this time I can't get the inside of the screen clean. The yellow/grayish tint on the left side of the screen certainly is dirt becuase if I turn off the iMac and shine a light on the screen, I see white dust/dirt at the exact same place as the yellow/gray tint. The 3 fans of the iMac blow dirt/dust behind the screen. This is a major design flaw. But I can live with it 'cause I know how to fix it, but now the dirt won't come off! Any idea's?
What kind of matierial/product should I use to clean behind the glossy panel? Can I clean the actual screen too? Or is it better to leave that alone?

I use iClean which comes with an anti-static cloth. Works wonders on displays, mice, and keyboards available here:

Bright areas on one side during black screen?

I'm being picky, but wanna make sure this is just how it is, and not a problem with my copy.
When viewing a black screen - that is, a screen of black content, the side that would be on the right when holding the iPad in portrait mode has a couple of brighter areas, like the old school backlit displays. It's not terribly bright, just noticeable in that case.

Hi All
I seem to have this on my IPAD 1 ... It started today.. after close 2 two years.. and it has been a very good ipad so much so that for two years it has taught my 2 year old son everything.. now.. I think after so many drops.. today i saw that I have on my right side of the screen am seeing these lighting areas as if I am watching a stage with spot lights.. moreover the brightness (auto mode ) is not workign and if i increase my brightness the right side starts heating up... plus i also notice a small gap at the point of the volume button... Now.. my Question is would an LC Change help it.. Wow.. I just noticed that on the other sides there is a little brightness as well.. but only the right side shows a splot light affect?? any idea

Cleaning iBook Display

Can anyone tell me what the best way is to clean the display on an iBook? Mine is pretty dirty and could use a good wipe down. I'm not sure what the safest way to clean it is. Any tips would be greatly appreciated. Thanks.

Apple recommends you shut down your computer and remove the battery before cleaning. Then you dampen a soft, lint free cloth (like microfiber) and clean the display. Never spray any liquid directly on the display--only apply it to the cloth. If a damp cloth alone won't clean it, then another safe thing to use is the stuff you use to clean eyeglasses with, although it can leave smears, so you would want to finish up with a cloth damp with just water. I don't know about iKlear for the display--it is recommended for the white plastic parts. Try a damp cloth first.
If the display is grubby because dirt is being transferred from the keyboard, then clean the keyboard too and in the future, put something between the keyboard and the display screen before closing. There are many products made for this purpose, but a clean 8 1/2 x 11 sheet of paper will serve.
Be gentle when you clean the display--it is fragile.
Good luck!

Unable to turn down display brightness

I just unboxed a new Macbook, and I am unable to reduce the display brightness. Neither the keyboard brightness (f1) nor the slider in system prefs > display work; you can pull the slider down, but then it bounces back to full brightness. Has anyone else seen this?

If you have the ambient light sensor on and are under bright lights, that could be the outcome. You can turn off the ambient sensor to see if that is the issue. The check box for this is right below the slider you referenced.

Non-technical: cleaning your display and kit

Nowhere have I found advice on this topic. After much effort, I thought I'd share my experiences. If you're like me, a bit OCD about your kit and its appearance, this is for you.
This works for glass/synthetic displays, as well as aluminium housings.
Your iMac display (perhaps your Cinema display) suffers marks from fingertips, drinks and food. It's an unavoidable hazard. My 2013 iMac is a case in point.
The iMac has a glass bezel, the Cinema display is synthetic. It's my experience that both will benefit from the same treatment.
I've used glass cleaners, (non-abrasive) polishes and proprietary solutions such as iKlear. No matter the solution, and the cloth used, streaking and smudging are the result.
My solution is:
a clean duster, wet, wrung out - if you use a new duster, it's too soft, try to get an old one;
a microfibre cloth, dry.
Use the wet duster to remove all filth, then dry with the cloth. Repeat. And repeat. And repeat...
This might seem obvious, but if you Goggle for this solution you'll find very little guidance.

Seems self-explanatory to me.
Displays
Disconnect the display from power, from its connection to a computer, and from any external devices. Next use the cloth that came with your display or another soft, dry cloth to wipe dust from the screen. If additional cleaning of the display panel or case is required use a soft, slightly damp, lint-free cloth. Avoid getting moisture in openings. Don't use window cleaners, household cleaners, aerosol sprays, solvents, alcohol, ammonia, or abrasives to clean the display.
Warning: Don't clean the screen with a cleaner containing alcohol or acetone. Use a cleaner intended for use with a screen or display. Never spray cleaner directly on the screen. It may drip inside the display and cause damage.

Automatically adjust display brightness via Terminal / Pretty good solution

This hint is for all of you who experience any problem with the adjustment of the display brightness.
*Short version*
After a cold and/or warm start, it sometimes happens that the brightness was changed by the system itself to its dim power saver setting or maximum value and sometimes - what a big surprise - remains as it has been configured.
I had spotted plenty of articles about this phenomenon, but none of them yielded a solution. I then decided to solve this problem by going the pragmatically way and use some kind of software which dims the display to my preferred setting. And the winner is: brightness.
This tiny program works perfect and you will love its benefit by using it in terminal - yes, brightness is a command line utility. On top of this, brightness is able to control different displays, internal and external. The clou: beside using the precompiled binary you can also download the source code here, modify it to make the program fit your needs and then compile it using Xcode.
1. Installation
Download a precompiled version of the command line utility brightness here and extract the binary to your desired path (e.g. /usr/bin).
2. Usage
"brightness -l -v" dumps the current display attributes (-v for verbose mode) while "brightness 0.5" modifies the brightness of the main display to half of its max value and "brightness -m 1 1" let a second display become shiny. Just play little bit around.
3. Automatically launch
Simply create a .plist file and drop it, for example, in ~/Library/LaunchAgents. Or make use of an AppleScript or a Terminal Script to let it launch.
That's it. Comments are welcome.
*Long version*
It seems to be, that the adjustment of the display brightness of an iMac and MacBook/Pro (maybe also other models are affected) drives a life of its own. After a cold and/or warm start, it sometimes happens that the brightness was changed by the system itself to its dim power saver setting or maximum value and sometimes - what a big surprise - remains as it has been configured.
I had spotted plenty of articles about this phenomenon, but only found terms like "Did you already disabled the ambient light sensor", "Did you already reset the PRAM?", "Did you already reset the NVRAM?", "Did you already…BLAH". Far from it, all of these tips have one thing in common: none of them yielded a solution. As a last resort, I thought, it was a good idea to install 10.6 from the scratch just to find out that the above mentioned phenomenon occurs right after a few days of using OS X.
I then decided to solve this problem by going the pragmatically way and use some kind of software which dims the display to my preferred setting. There are a few applications to do this, but always it was necessary to drag a slider or type in a value to dim the display, so none of them allowed an automatic configuration. No, I am not a very sophisticated person, I only prefer to use software which is simply well-thought-out. And the winner is: brightness.

3. Automatically launch
Sure, OS X provides different ways to launch a program automatically. If you are an enthusiast, feel free to use the one you prefer and stop reading, because you are already finished. If you are not that familiar to OS X take the next step as an advice.
An easy way to trigger OS X launching a program automatically is to add the desired program to your Login Items. But, in this case, it will not work the easy way, because we have to launch a so called classic command line utility with a given option. It is not like starting Mail or iCal, which appears as typical applications to OS X. You must start brightness via Terminal by typing "brightness 0.5" (without quotes) to modify the main display brightness to half of its max.
We now use a Launch Agent. Just create a .plist file, e.g. com.brightness.plist, with your favorite text editor. For the lazy ones here comes the template (simply copy and paste):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Disabled</key>
<false/>
<key>Label</key>
<string>com.brightness</string>
<key>ProgramArguments</key>
<array>
<string>/usr/bin/brightness</string>
<string>.5</string>
</array>
<key>RunAtLoad</key>
<true/>
</dict>
</plist>
Save the file in ~/Library/LaunchAgents, if you want brightness to be executed everytime you log in.
You could also use an AppleScript. Copy and paste this code "do shell script "brightness 0.5"" (without the leading and closing quotes) to a new Script. Then choose Save As and enable the Option to make it Execute only. Now add the Script to your Login Items.
Another option is to use a Terminal Script. Copy and paste this code
#!/bin/bash
/usr/bin/brightness 0.5
exit 0
and save it as, for example, brightness.sh. Make the Script executeable and add it to your Login Items.
That's it. Comments are welcome.

Thanks. Works great. I made a ScriptBundle and a User Agent (launchd) . So if someone sets the display brightness to maximum, it automaticaly corrects it at next login.
The ScriptBundle contains your mentoined command line utility and the following applescript:
do shell script quoted form of (POSIX path of (path to resource "brightness")) & " 0.7"
Be aware of the space in " 0.7" or whatever value you have set.

IPad2 display colors are strange.

iPad2 display colors are wrong. When I reboot the device by holding down both the home button and the sleep/wake button for 10 seconds, the screen with the Apple logo in the center is bright red instead of dark grey. Does this indicate a hardware fault? Was working normally until a few days ago.

Settings>General>Accessibilty>Invert Colors>Off. Did you check that?
I just checked on my iPad and apparently that is not the problem. If your screen has turned red, try tapping the iPad on the back a couple of times and see if that helps. Read this discussion.

@ psyhcomania
dis is wat some else stated on the other post. but this is for the n78.
"i discovered that the brightness now depends by the sensor near front camera! if u put the n78 under a lamp 4 few secs it'll be soooo briight! then if u close the lamp u could see the brightness going down! this sensor is reallyreally sensitive with the firmware n° 11.043!
i found another problem: the speakers quality. It's really bad if u put the volume at max! i hoped it will improve with the firmware uptading... but it was just a hope N73's speakers are better! "
maybe its a new kinda of features or something.

PCM-M10 Display Brightness

I got a PCM-M10 recorder, and it's great.
My only complaint is that the display is too dim. As far as I can tell, there is no way to adjust the brightness. I've seen photos of the PCM-M10 on the web, and the display appears MUCH brighter than mine. But the photos could have been maniuplated, of course.
Does anyone else have this problem? I'm thinking I may have a defective device.

I got another one, and the display is exactly the same. Lesson learned: Don't trust the photos that you see online. It's not at all bright. But I'm convinced that this recorder is the best of all that are available. Too bad Sony had to fake the display brightness in their ads.

Using two external displays that are NOT mirrored

i have a MBP early 2008, meaning the external display port is a dual DVI-I port. I have have two external displays, both samsung syncmaster xl2370 with native resolution 1920x1080. i have a dual dvi-i to vga splitter. when i connect both displays, they mirror one another, which is not what i want. rather, i want to have my MBP display, and two external displays that are not mirror images of one another. according to apple, if i buy a dual dvi-i to dvi splitter, i get the same effect. i've read on various forums about hardware alternatives, like buying a usb to dvi or usb to vga adapter, with some reasonable results (except a bit of sluggishness). the best one seems to be the diamond: http://www.diamondmm.com/BVU195.php
it mostly gets good reviews, but is sluggish. does any know of any better options?
many thanks, jovo

Welcome to Apple Discussions!
USB is slow partly because it is processor and driver dependent. Best to go with a straight video solution, such as Matroxes products like this one: http://www.matrox.com/graphics/en/products/gxm/dh2go/
