Intel 20"iMac screen seems too bright

I just bought a 2Ghz, 2GB Ram, 20" intel iMac. The screen seems to be washed out/too bright even after the brightness is adjusted. Is this a common problem? What is the remedy?

I have the same issue. I do a lot of digital photography and my prints should look close to what I see on the screen. My older eMac and MDD G4 w/ a 20" flat LCD screen gave me excellent results. I was struggling with the color profile on this new iMac (2.4 GHz Intel w/ 20" GLOSSY screen). I got close selecting the Adobe 1998 profile and adjusting the brightness down to about 60%. This helped but I'm not 100% satisfied. I called Apple and one of the tech support engineers suggested I also go into the Universal Access setting and adjust the contrast ever so slightly. Again, this is moving in the right direction and I need to view this setting for a while before I say it's what I'm after. It does help. Also, go to birdphotographers.net and select forum and go all the way to the bottom of the screen, they have a great step wedge to verify you monitor settings, you should see all steps w/o saturation.
Good luck,
Rich
b.t.w. disregard my old profile-I'll do an update.

The color of screen seems too bright

I've just upgrage my system. The fonts of tty became very small and very bright after that. I just startx as usual but find the color of screen is so bright that I cannot see the fonts clearly and and kwin effect disappear.
I've reinstall my video card driver and remove xorg.conf but it didn't help. any ideas? thx~

Can you try the DVI connection?
Does the problem disappear when you disable KMS?
The font in the TTY is probably small, because of the higher resolution that is possible with KMS. You can change the font size and the colors for the text in the TTYs, though. I can send you more info on that in some hours if you want.
Thanks !
The problem disappear when I disable KMS.
I do not have a DVi cable so I cannot try DVI connection.
It seems a known bug.It has been reported and discussed a lot here:

Definitly sounds like a physical issue with the phone. I suggest you go to your local Apple Store or Apple Authorized Service Provider for help.

14" imac 1.83GHz LCD screen suddenly too bright

My computer screen is suddenly too bright with a sort of a white washed look. I've checked the display settings and brightness in System Preferences and played with the greyscale and white on black options in the Universal Access panel, all to no avail.
I hooked up an LCD projector and the projected image is perfectly normal while the computer display is impossible to read. Even the most dim setting is too bright. Help!

Welcome to Apple Support Communities

IMac 24" Display too bright

Even after dimming down the brightness of the iMacv 24 inch screen to lowest setting, I still find that its way too bright for my eyes. I have tried to use Shades for Mac OSX and it works fine, however for Windows Vista, I cant find any solution to dim down the brightness without changing my Color profile. Anyone out there can help me with this?

A recent Apple software update for the Alum iMacs may be addressing the brightness issue. In a previous post the following was said regarding the details of what's in the update...
After opening the installer package in "Pacifist" (an installer package viewer /extractor) utility), I >noted that revised ATI drivers (last revisions in iMac Software Update 1.0 a few weeks back) are the >main feature. The GLEngine translate item also updated together with a DisplayProductID-9c6a file.
The above may mean that the ATI HD2600 PRO video card may now run at full specification (a la >Vista)! The display product file may mean improvements to the 20" Al iMac's display..."
And in another post someone was also asking...
anyone notice their brightness lowered recently?
which also referenced this same Apple Update. Please let us know if it helps!
Here's a link to the update.... http://www.apple.com/support/downloads/imacsoftwareupdate11.html

Screen Contrast Too Bright - Changed Itself

My mother-in-laws AIO computer monitor is too bright. The contrast changed automatically. No updates were done. I ran diagnostics, changed monitor settings, reset defaults. Nothing is changing the end result. Is the monitor just dying? It's an all-in-one. It is less than three years old and not used very hard. What else can I try to troubleshoot? I was going to hook up a second monitor, but b/c it is a AIO I don't believe it has a cable to plug in a 2nd monitor.

This is weird. All I did was squeeze the case near just at the top of the LCD display and the lit screen SUDDENLY had the written display again. As I said the ipod worked but I did not have a written display. With that little trick the ipod returned to normal. About a week later , the ipod had a relapse and squeezing the case dont remembe whether it was the left or right side, brought it back to life and it has behaved itself for the past 3 months. I hope this information is useful to others with the same problem who do exist.

Satellite A660-18N - Screen it too bright so how to update the BIOS?

Hi guys, I need your help with this laptop because it is giving me a lot of problems.
I have changed the screen of this Satellite A660-18N because the one that was fitted in was damaged. I have installed it and is working fine but I'm having problems with the brightness. When I click - on the brightness it goes up and when I click + it goes down. It's way too bright and want to do something to fix it.
Does the bios help to fix this problem and how do I flash the BIOS on these laptops? I did flash BIOS on desktop pc but on this I can't see any way of doing it. Is there any way of fixing the screen without changing the BIOS? Some people said that I have to flash the BIOS because new screens wont work 100% with old BIOS.
Please help
Thank you

Thank you very much Xardas for your reply.
It is 3rd party screen. I bought it from ebay. They said that it's original. It says made from Samsung. The original one was also made from samsung. The guys from Toshiba said that you might have to update bios so that it will accept other screens. I told them which one I bought and they did confirm that it should work fine.
I wanted to flash the bios with the latest bios and maybe it could work fine. I just don't know how to do it? I did create a bootable usb and placed the bios in it but don't know the command to flash it. I did go in bios but did not find anything that would be helpful to flash.
I also was thinking to use some kind of software that makes it little bit darker. It's way too bright. My eyes hurt to use it. I always have to use sunglasses.
If you know anything it really would be helpful.
Thank you

Satellite P300-P19: screen is too bright

Hi all
I have a P300-P19, the screen is so bright, its set at LEVEL 17.
I have to use FN + F6 to drop it to LEVEL 1 constantly.
Does anyone know how to set it so it stays at the LEVEL you want ?
And is there any other options for contract etc etc
Its even to bright at LEVEL 1 but i do hate bright lights... :-)
Thanks in advance..
Rob

LOL :D if you hate true bright screens so why you buy devices which support such True Bright screen technology?
I love such screens I like it in the LCD TV, external PC LCD and in notebooks...
However, if you want to use constantly low screen brightness then I recommend changing the screen brightness option in the Vista Power settings.
Check the forums HowTo area.
There you can find nice document called How to handle the power managment features of Windows Vista?

Suggestion to iPad developer: the screen is too bright for an E-reader

Hi,
I have been using kindle DX for reading e-book and newspapers for a year. I bought the iPad and have been using for a week. iPad has many advantages over Kindle in many ways(very fast, zoom-in zoom out, great apps for editing PDF, and many more) however, it lacks the appreciation of the display for reading. *_The brightness is quite too high(even when you try to lower the brightness setting to lowest). When I read WSJ or PDF for a while, my eyes go very very tired. It is fine in the apps like Kindle or iBook or GoodReader where you can adjust the brightness even more._* So you could read with the same light intensity like the kindle or other e-reader. However, it is still very bright in safari or WSJ apps where you cannot adjust even further. You cannot use iPad to read something in the dim light environment with this lowest brightness adjustment.
I made an appointment to the Apple store to discuss about this issue. I also compare the brightness adjustment to MacBook and other device. You can eventually dim the screen even more and more for other device except the iPad. You could also dim the brightness even more for an iPhone. The technical support told me to send a suggestion to the iPad developer so that they can do the adjustment for the next OS Update.
*My advice is to increase the range on the dimmer side of the brightness. You could also add the option to adjust for the contrast. In this case, you will have low light coming out of the device and the character is still crisp by lowering the brightness and increase the contrast of the display. The eye strain problem will be significantly reduced.*
Many of my e-reader colleagues also complain about this issues. So I hope you take this into serious consideration. Please Adjust the brightness range and everything else should be perfect. You could even think about the display like Mirasol display for the next generation of iPad as an option for display rather than only IPS LCD. This will help the e-reader oriented like me to stick with iPad forever
I strongly hope there will be some of these changes in the new OS update. Since you guys want the iPad to be one of the option of an e-reader, then the display and the brightness is very very very important.

I adjusted everything including turning the auto brightness off( like I did for my iPhone ). And you could see that the lowest brightness of the iPhone is dimmer than the lowest level for the iPad. I have no problem reading on the iPhone without that level of brightness either. This is the only reason that I don't like about iPad and the small adjustment should satisfy all my need. I don't see any reasons for returning it.
Moreover, the eyes sensitivity to the light level or brightness for each people is different. It's correct that you and some of my friends do not have difficulty reading with this level of brightness. But some of my friends and I are having this problem in safari and the apps that do not have further brightness adjustment.
The best way for me to avoid this problem now it to alight the iPad 75-90 degree to vertical so that the light does not come directly to my eyes when I use the apps that does not contain brightness adjustment. This way reduces the light traveling to the eyes from iPad. The brightness goes down a bit more. That is why I said just reduce the lowest level to a bit more then everything is great.
I also try the inpicio anti glare to reduce the light from reflection but this does not help either because it produces bad image output and does not filter any light out.

My Imac screen seems to be frozen,what can I do?

My relatively new I Mac seems to have just froze when I was installing Microsoft office onto it . My cursor is working, but the screen is just a white. Is there anything I can do?

I think I would reset the SMC and then delete the software that seems to have been associated with the problem.

06 intel 20" imac screen gets darker at bottom

just started uup the computer this morning and found that the screen fades to a darker tone down the screen.
http://farm2.static.flickr.com/1031/132232444748b3e99079b.jpg
anyone else had this or can anyone offer solutions, iv run out of warranty and support.

Both. My 20" iMac at work has the same problem. It is common on the ALU 20" iMacs and yes I would say it's defective. Apple may not agree though.

Why does my iMac screen seem to be flickering everytime I launch an app since Mavericks update?

Am I the only one who is having this flickering thing (for 1 sec) when an app is launched? This only started right after the Mavericks update, I don't know if it's iMac related or if everyone who updated to Mavericks got this.

Do you have any external drives attached that may have an older version of iTunes on them?
I wonder whether reinstalling (one more time) using the standalone installer rather than the App Store may help get round the problem:

Brightness incosistency on 24' imac screen

okay i got my 24" imac this week and fired it up last night. today i noticed somethingthat kind of bothers me. on the left hand side of the screen, everything is brighter. toward the middle, it seems to be a little darker and on the left hand side, the right 1/3 of the screen is slightly darker. any problems with this? am i going to have to send this bad boy in? it is i would say 5-7 % darker than the rest of the screen. any suggestions welcome! thank you! is there any kind of demagnitizing reset button like on some pc monitors?
luke black

Hi Al,
Thank you for taking the time to write and offer advice. I already have taken it back and Apple told me it was within their specs. I am definitely returning this unit; the only question is whether it will be for exchange or refund. If all 24" iMacs look this way, then I won't bother exchanging it. That's why I would like to see photos of other people's screens, if possible, to see if I detect similar issues.
The screen shot I posted is an actual photo. As I mentioned, I have adjusted the brightness and contrast of the photo in Photoshop to make the variation more easily recognizable; but these color and brightness variations are readily visible to me under my normal working conditions (which is what prompted me to take the photo in the first place). I also recognize that since I am a graphics professional, I may be more aware and less tolerant of display problems than more casual users. I think my current 20" (non-Apple) screen looks quite good, so I know it's possible to have a good LCD. I just don't know if the 24" iMac is capable of this performance by design.
Best Regards,
- Michael

Screen too bright at night

I've just bought a 24" iMac and find the screen far too bright in the evening and at night when I often work. I have the contrast and brightness down to the lowest settings in System Preferences, but the screen remains so dazzling that it hurts the eyes. On my MacBook Pro I can slide the brightness down to black if I want, so why not the iMac - or have I missed something?
All thoughts about solving this problem - or suggestions for software to reduce the brightness - greatly appreciated.

I would like to thank Lenn and Dennis for your suggestions, all of which I have now tried. I've taken so long to respond because I wanted to wait 24 hours - and another night - to see if one is better than another. Changing the screen profile made a very small difference, and at first Brightness seemed to do a better job, but the overall winner in terms of flexibility is undoubtedly Shades, which I'm using right now.
Thanks again, both of you!
