    Just installed windows 7 on my imac, the only problem is that at the lowest brightness (set via keyboard and boot camp utility) the screen is too far bright!! Is there a way to low brightness via software?

    Yes it is ridiculously bright even on my 24" iMac. This latest BC3.1 update didn't fix it. :mad:

    Yeah, I have my 27" iMac brightness setting on zero and I'm still wearing a welding helmet to look at the screen.

    I'll have to look around, perhaps there is a utility for ATI cards allows to adjust the brightness. I can't remember if the Catalyst thing has a brightness setting.

    All I know is right now as I type this message, the background is blinding.

    Try calibrating the display in the Windows Display control panel applet. It may be that your gamma is just too high.

    Control panel/Gamma is not making it better. (21.5" iMacs, Windows 7)

    Is there a brightness utility for Windows 7 (like Shades for Mac)?

    Try under the power settings

    I have a 27" iMac and I don't have a brightness option in BootCamp. I was able to dim my screen's brightness using the Power Options in Control Panel

    Anyone figure this one out? I tried loading the icc file from the OSX side to see if the color profile would help, but the screen just radiates heat and is SO bright.

    I've installed f.lux which helps a bit, you guys could try that till we get some better support from Apple.

    Have you tried Dimmer or Desktop Lighter?

    I've also thought about inverting the color scheme to reduce the amount of white at night on my too bright LCD, using something like PowerStripe (caveat: not sure this works with iMac setups, haven't tried!)

    If you calibrate your display (press start and type 'calib' in the search box, it'll come up as 'Calibrate Display Color') set the Red Green and Blue to 0 on the final page, it makes the brightness much less, but perhaps too little. I am going to have it like that though, because it gives me a headache otherwise.

    Has anyone tried if the brightness problem is resolved under Boot Camp/Windows 8?

    Managed to reduce the brightness!

    Tried all sorts of third party softwares but nothing could save my eyes... Finally, I tried looking for some adjustment panel in the Catalyst control center and it worked!

    Here is what I did:

    1. Right click>Click on Catalyst Control Center
    2. Goto My Built-in displays tab on the left side panel
    3. Under the drop down click on Display color
    4. Reduce the contrast value. I've set it to 5 as that suits my room light conditions.

    Hope this helps. Good luck guys.

    I run Win 7 Pro on both my iMacs and you can adjust the brightness on the "Power" icon under the Control Panel. No needd to buy of install anything, it is right there.

    And boy does it need adjusting. As I remember the screen backlights are WFO!:p
