Display keeps dimming

I am trying to watch tv on my imac with eyetv 2, but the display keeps dimming after about 2 mins. I have the screen saver set to come on after 2 hours and i also have set it to 2 hours to set the screen to sleep. How can i stop the screen from dimming when i am trying to watch tv. I must note this is only when i am wathing it in a window and not full screen. Any help would be great.

I think that there is a glitch in the Energy Saver system pref.
My Mac dims the screen after about 60 seconds, regardless of whether the check box to dim the screen is selected in Options or not. This is irritating when reading news articles, watching video, etc.
The fix is, as Barry said in his first post. Go to System Prefs/Energy Saver/Options and check the box Automatically reduce..., then exit the Energy Saver prefs by selecting Show All or quitting System Prefs. Then return to System Prefs/Energy Saver/Options, uncheck the box and quit System Prefs. Your screen should not dim any more.
However, if you restart the Mac, the problem will return and you have to go through the fix again to get it to stop.

Display keeps dimming after 30 seconds, randomly!

After 30 seconds or so, the brightness will dim. I know this can be turned off (at least I think), but I can't figure out what is causing it. It also seems to be random, but that may just be my imagination.
How can I keep my display from dimming after 30 seconds? Thanks.

You might try to reset the SMC and/or PRAM.

It's the same... if you click restore defaults, which mine was, they are both set the same.

RANT: Why does screen keep dimming even when "DIM" is disabled?

ARGH this is buggin' me!
I turned off the dim under custom in energy saver. i am reading a document and it keeps dimming and it's annoying as doo doo. anything i can do?

What about the option of "Automatically adjust
brightness as ambient light changes" in
Preferences/Displays?

William - anyone with this problem I can guarantee
shut off every screen dimming option.
I have this issue. It seems to be intermittent.
What seems to improve it - Restarting, or unplugging
and re-plugging in the mag safe charger.
These have been my only solution. I have even turned
off all display changes for battery power so that
there shouldn't be any "confusing" factors for the
computer.
I wouldn't care so much about this issue if it wasn't
for the screen whine with decreased brightness.
I trust apple will fix this with software or firmware
updates.
I checked my 1.67 PB 15", it does what is being described. Software?

My screen keeps dimming automatically

My brand new Macbook Pro's screen keeps dimming the screen all the time regardless of which setting is it on. Its the first time it does that today and it's so annoying!!!! I have the following options: Put the hard disks to sleep when possible, slightly dim the display when using this power source, automatically reduce brightness before display goes to sleep and restart automatically if the computer freezes.... The only thing that is check marked is Put the hard disks to sleep when possible and automatically reduce brightness before display goes to sleep... Any advice? I googled a bunch of stuff but I don't have the options they give to help my problem such as un check the automatically adjust display or what not...
Thanks

I dont have that option available....
You have to go to System Preferences > Displays (not Energy Saver where you were).
If you really don't have it, and you have an external display attached, that's the reason why. If that's the case, let me know, and I'll give you directions to do it.

Screen Brightness Keeps Dimming

My new Sony SVS131290X laptop will not keep it's screen brightness lit. It keeps dimming by itself. I have tried setting the function + F6 key, going to power options and adjusting the brightness there, and also tried advanced power options. It dims after 30 seconds. Has anyone else had this problem?

Hi everyone, I just recently purchased a Sony Vaio Pro 11" and I have been struggling with this issue the past 2 days, and now I have a proposed solution! Prior to doing this I had tried two things (outlined below) and neither of them fixed the issue for me, so if you are in the same boat this might work for you too. WHAT WORKED for me was going to the graphics properties control panel:Right click on the Desktop home screen and select "Graphics Properties" > click the "Power" tab > click "On Battery" > and under "Display Power Saving Technology" click OFF That fixed all my auto-brightness adjusting woes. Hopefully this helps someone else The two steps I took that didn't quite work:1. Went to Vaio Control Center > Image Quality > turned OFF the auto brightness = still had the dimming issue2. Went to the Start screen, scrolled down to the apps section and in the search bar > typed services.msc > opened up Services > clicked "Sensor Monitoring Services" > went to the drop down menu and changed from "manual" to "disabled" and restarted my laptop = still had dimming issue

My ipad2 screen keeps dimming and staying that way. And I can see the reflection of the app I most recently closed. Help?

My ipad screen keeps dimming and has ghost images of the previous open app. Can this be fixed? Help.

Did you ever resolve this issue? I have an iPad with a similar problem. After a software update the screen went very dim. I have just finished trying to restore the iPad to the latest iOS 8.1.3. The display is still very dim. The backlight does change when you adjust the brightness slider but at maximum brightness it is just barely possible to see what is on the screen. What makes me think this is software related is, like you said, there are remnants of previous screen images overlaying the current screen. For example, when I restored the ipod, I enter DFU mode so the screen showed the "Connect to iTunes" images. After restoring and rebooting there is not change but the "Connect to iTunes" images are still showing up on top of the normal screens. Even if I power off the iPad and turn it back on that image still appears as if it is permanently burned into the LCD. There are more previous screen images appearing underneath the current screen as well (e.g., I can see the System Settings window faintly under whatever screen I'm currently on). Would like to know if your problem required a new logic board, new LCD, or if you were able to resolve it with software tricks. Please respond if possible.

My display keeps changing to 800x600 after upgrade to 10.8.3

After upgrading to 10.8.3 my display keeps changing to 800x600 after it wakes up from sleep. I have to go to preferences and set again, and it works. It is quite annoying. Any clue.

Not much to go on.
What monitor and connection method are you using with the mac Mini..?
Have you tried resetting the > NVRAM and PRAM
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.

If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Ignore any other messages that appear in the Terminal window.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.

Why does my screen keep dimming and brightening?

I'm just sitting here in front of my fire during a mid-March snow storm in Maine, and my screen keeps dimming and then brightening. It's getting quite annoying. What is going on?

OK, I figured it out - it's the auto brightness adjustment. Found the answer in the pane to the right of my comment.

My AppleTv keeps dimming as if it is in energy saver mode. My DVD player and TV do not do this. How do I disable the energy saver feature on AppleTv? BTW this is my second AppleTV device so it does not appear to be a product defect.

My AppleTV keeps dimming as if it is in energy saving mode. My TV and DVD/Netflix player do not do this. How do I disable the energy saver feature in AppleTV? BTW: This is my second AppleTV device so it does not appear to be a product defect.

I keep seeing versions of this same question, and it's always the same answer: it's the TV. Well, it happens to me as well. But it only happens when viewing programming via Apple TV. My cable is totally fine: no dimming. Only with Apple TV. So what's the answer?

Display too dim

I am running Windows Vista in Boot Camp on a mini. The display is an Apple Studio Display connected to the mini via an Apple DVI to ADC Adaptor. The keyboard is an Apple Pro Keyboard with no brightness controls. After Windows boots, I login, the desktop comes up, and then the display automatically dims to its lowest setting. Pressing the button on the display, which brings up Displays Preferences in OSX does nothing in Windows. The Boot Camp Control Panel in Windows has no brightness controls. I am running Boot Camp 2.2. The display is too dim to get any work done. Any ideas how I can brighten the display?

Why does my screen keep dimming?

Screen on macbook keeps dimming after a few seconds, even when I put it at the brightest and I'm in the middle of using it.

If that doesn't help, perhaps this is your cause:
