My monitor seems to be losing brightness.

My iMac monitor seems to be losing brightness on the left half of the screen. Is the monitor going out? I've only had it a year...and where can I get it fixed?

I concur with LousyFool, it sounds like a bad backlight and the display need to be service or replaced.

T500 with External Monitor Seems to Be in 8 bit Color

I got a T500 for work running Windows 7 x64. I hooked up the computer to an external monitor via the VGA port (I've connected directly to the laptop and also through the Thinkpad dock).
Despite my best efforts the external monitor seems to render in 8 bit color mode (or maybe 16 but definitely not 32 bit). You can tell by lack of color in the gradients. Things I've tried.
Updating the video drivers
Using the IBM monitor tool to set it to 32 bit
Setting it to 32 bit in the Windows settings

Just to close the loop on this, I've determined that the cause of my issue is the Intel Dynamic Platform and Thermal Framework software/driver. I've disabled in the BIOS for now, and the machine is working very well. Will look for an update from Lenovo to address more definitively.

Hi A,
You have 3 months of free AppleCare phone support, and a 1 year hardware warranty. If I was concerned about anything on my new MBP, I'd contact Apple.

Sudden monitor seems not working after change HD

Hi Folks,
after I change my original HD which is made by Hitachi to Seagate Momentus XT, my sudden monitor seems not working again, in perviusly if I take my MBP up from table with a strong accelerate, a sound like "ka-da" would be heard from HD because of the arm in HD reset to its initial position, but now with the new HD, this issue has never happened again.
anybody know why? please do me a favor, thank you.

My reference monitor seems to be missing the setup option also it is displaying in a format I do not understand.

I'm based in th UK and working with PAL mini DV. I imported the footage in and then created the sequences using a clip, so the sequence settings should be correct and having checked them, it seems they are. Admittedly, I've never used this function before and this: http://library.creativecow.net/articles/devis_andrew/YC-Waveform-graph-Premiere-Pro/video- tutorial is my frame of reference. The problem I have is I cannot convert the scale he is working with (IRE) to what I'm working with (V).

Apple TV. Just upgraded software update. Now I seem to be losing the connection to my iTunes Library rather frequently. Any suggestions ?

I have recently updated the software on my Apple TV. I now seem to be losing the connection to my iTunes Library on my iMac rather frequently. I have reset/restarted Apple TV box, my BT Infinity box and my iMac. I would be grateful for any advice.

Welcome to the Apple Community.
You can't play music from the computer if there is none there. If you are using iTunes Match you should now be able to download and play all your music on the Apple TV from the music feature on the main page.

My Apple TV seems to be losing its "link" with my computer.

My Apple TV seems to be losing its "link" with my computer. I'm running Windows7. The iPad, iPhone, & iPod have no trouble pushing content to the Apple TV but the iTunes library of music and movies does not want to connect or load. Has anyone had any incompatibilitites with Windows 7 or problems of this kind?

Screen losing brightness / spontaneous shutdowns

2 Problems:
1.) My iMac G3 400 / slot-loader / OS 9.1 has had recent startup problems; i.e., occasionally shuts down spontaneously shortly after initial startup, or sometimes after several minutes, or longer use.
2.) The monitor has become darker. I brightened it a bit via the Monitor Control Panel, but it is still too dark.
Any help will be greatly appreciated. Thanks.
iMac G3 SE 400 mhz Mac OS 9.1.x 384 RAM 16 GB HD DSL Modem

I'm no expert, but experienced the same issue. I believe that the iMac is not retaining enough charge for the monitor (26,000 volts for minimum brightness), which is why a) it's so dim, and 2) other parts (hard drive, etc.) pull so much power during startup that it kills the machine.
This is what I did to rescue my iMac while I look for another machine (you should try all software methods [permissions, pram, system disk, etc.] before you do this):
1. UNPLUG.
2. open the memory door. Reach in and disconnect the CD drive (you may need to take out the memory cards for better access). It's a little snug in there -- you may need to get out some needle-nose pliers. The plug is the SMALLER (and outmost) of the two black boxes leading into the cd drive. The other one is soldered onto the cd drive itself, and -- ahem -- shouldn't be yanked out.
3. re-insert your memory cards if needed
4. Plug back in.
5. Try powering up. (zapping PRAM might be a good idea at this time, too)
6. Let it sit with its "?" (hey, where's the system?) icon for a while -- I believe this builds a charge large enough to :
7. Unplug, reconnect the CD drive, and power up.
If you have sucess, NEVER shut down (sleep was okay for me) unless you want to go through this process again. It seems the capacitor isn't holding charge on power down, or that the trickle charge isn't trickling well. It could also be that the charge is TOO large, but I doubt that.
Anyway, that is what worked for me. I'm typing from said iMac right now, and looking for a new one right now before it gets really scary...

I have sensory issues. How can I find an external monitor that isn't too bright?

I have sensory issues which make bright lights very painful. Some monitors are too bright to look at. I chose a Macbook Air, in part because Apple allowed me to dim the screen, but I wanted to find an external monitor so I could use the Macbook as a desktop as well as a laptop. I recently tried an Aoc monitor, but it doesn't allow me to dim the screen enough without special software. I would rather not have to use extreme settings [Brightness 0] and special software [Easy on the Eyes] to dim the screen. I had tried comparing brightness in-store, locally, but I guess I couldn't tell because the store was full of bright lights, and because I was wearing sunglasses to cope with the bright lights. Can anyone suggest ways to find better more accessible monitors?

There are two ways. Likely if you have the money, the Apple monitor would likely be the best options since it powers your macbook and other stuff as well. It is expensive though. For a nonApple monitor the feature you are looking for is called backlight level. The brightness control doesn't actually control brightness as might be expected because it modifies the signal. The backlight level however does control the brightness of the backlight itself, like the buttons on a real mac. You won't be able to use the buttons on the keyboard though. So when you go shopping, make the salesman show you this feature in the store in the monitors interface and you should be good to go.
Also, if you are sensitive to bright light, did you know about the ability to assign a single key on the keyboard to invert the screen instantly? I prefer white text on black myself.

Monitor colors funny and too bright after 10.3.9 update.

Hello all. I updated to 10.3.9 last night. Now my monitor is way to bright and looks bad. I tried all the usual stuff. Any ideas? The monitor is a Samsung 793MB and it was great until the update. I tried the "detect monitor" and even tried to calibrate but it's still a little off.

A bit of a long shot, but after suffering a color issue with my G4 mini yesterday, try unplugging the video connector(s) and then reconnecting firmly to ensure it all fits together tightly. Any slight looseness can cause color variations, brightness or contrast imbalance and even image stability issues.
Next, open the Universal Access preference pane and ensure that under the Seeing tab, the Display slider is set to Normal.

Display losing brightness

I could be wrong but when I look at displays of newer MacBooks theirs seem to be brighter than mine. I've had it for about 2 years now so maybe thats normal or is there something I can do to bring the brightness level or range back up?
Also, its not that I can't see clearly the screen but it just looks about 10-15% dimmer than other MacBooks I've seen and my whites don't look as white as others
Thanx in advance

Welcome to the Forums!
The new 15" MBPs have LED backlights, so they are brighter and "whiter". Apple claims the 17" models are brighter too. So it's not your imagination. However, the CCFL (fluorescent) backlights like yours (and mine) do age, and though they don't get significantly dimmer, they do take longer to reach full brightness (up to 15-30 min for displays that reach 5 years old or so).
Hope this helps...

SCREEN LOSING BRIGHTNESS!!!!!

hi, this june will be the one year birthday of my ibook g4 12" i have never had a single problem with the laptop but recently i noticed the screen has gotten a bit dimmer. i can still see everything on the screen but its no longer the vibrant bright screen it was. i wish it was because my computer was old but i havent even had it for a year yet !! does anyone have any suggestions on how to brighten up my screen (and yes brightness is all the way up) thanks a lot.

Since most Apple resellers will forward your portable computer to Apple,
you may as well go into one that is nearest where you live and let them
check with Apple online about your warranty coverage; and take it in.
Proof of your coverage should be in the main Support computers, but
if you have a dated proof of purchase for your computer, it may be nice
to also have that on hand if you carry in your machine for service.
You'd be charged to call in after the initial 90-day phone support, unless
you got the AppleCare extended Protection Plan; which would also (from
new) add up to three years Service -repairs- and phone support. Support
can help also in cases where a new user has an issue with software; but
the Service portion on the original one-year complementary coverage is
the repair portion you need to fix this; before it expires.
If you do get the AppleCare Protection Plan extended coverage plan, it
would be handy in the future and it can be transferred to another owner.
Also, should this problem as you see it, not be viewed in the same sense
of urgency by some tech advisor, with this extended policy in effect, the
issue would have a case number and should it get worse or fail, the item
would be in their system ahead of the actual event. That can be helpful.
Nearly any Apple reseller should have the AppleCare for iBook/MacBook
policy in stock; you can also order them from Apple online, or from an-
other Apple authorized reseller. Just so long as the physical item they
send you (if ordered) arrives before your purchase anniversary deadline
AND subsequent lag times before you enroll the plan directly with Apple.
If you buy it -but fail to enroll it- the policy is about worthless to your Mac.
Un-enrolled (unused) policies appear sometimes in dubious places for
sale; I'd avoid eBay resale Apple plans because you may get nothing. A
company called LA Computer seemed to offer the AppleCare plan for a
time, at a discount; not a great sale, but a little off to encourage one to
buy hardware and other things from them. The policy is about $250; and
that is a bargain against the price of a logic board. It is a good accessory.

After the last upgrade of OS X Mountain Lion I can't seem to adjust screen brightness anymore. Why and how do I solve this?

My screen brightness used to adjust itself and if not I could use f1 and f2 keys. After my last upgrade of OSX Mountain Lion, these do not seem to work. Does somebody know what happened and how I can return to the original situation?
