I don't know why, but the screen seems dim to me at max brightness. Is there some kind of software tweak I could use to bump it up a bit more, or is it at the hardware limit?

Now don't hold me to the results of this, but i heard that if you just toss that bitch out the window of a car speeding down the highway at 80mph+ the screen become just a tad brighter.

But in all honesty i head that from a homeless guy tripping on bath-salts so...

Sorry, I don't get the joke (or reference?).

Don't know of increasing brightness
He was just joking throw it out the window

when i need turbo boost in my honda civic, i turn off the AC. Maybe you can do the same and run your brightness at 70 percent for an hour. then crank it to 100 and itll look like 300 percent!

seriously though. no, thats all youll get. its as bright as itll ever be.
 
It's a limitation of the power of the LED backlight and the amount of light that the higher density display lets through.
 
Hi OP. There is one thing you can try that may make a little bit of difference for you. In the Display settings if you go to calibrate, in the wizard the second thing that comes up is the Gama. Setting it to 1.8 instead of 2.2 seems to help a little bit. It was discussed in another thread. This also helps with giving the display more discernible contrast in the dark greys and blacks.

I agree with you on the brightness, for me the max brightness is ok, but I wish that it would be able to get brighter. The max brightness should actually be somewhere between 50-70% of the max. Probably just a result of 1st gen technology. Hopefully the next generations give us brighter screens!
 
It would be awesome if Apple would have offered a tradeoff of brighter backlights with worse battery life...

is there any negative effect of changing gamma to 1.8 from 2.2? anything to compromise...

Unless you're primarily using the MBP for photo work, graphic design, or other areas where color accuracy is critical, the gamma setting is really a matter of personal preference.

If you are doing mission-critical photo, video, and graphics editing, it will give you an incorrect rendering of shadow and highlight detail. Not good if you need your client's view to match yours.

I must live in a cave, because even in daylight conditions, max brightness has always been bright to me.
 
Maybe it's because I'm used to IPS LCDs (which tend to be a bit darker than TN panels), but I find the rMBP's brightness to be perfectly usable. Max brightness hurts my eyes indoors.
 
Turn off automatic brightness settings.

I found that mine would dim in a relatively dark room...

Plus it really hurt my eyes trying to read something with it going up and down like that.

That affects midtones more than anything. The closer you get to white, the less it changes. Beyond that you're not even changing the hardware behavior which is set up for 2.2. You're just redistributing the values to 1.8 if you create a 1.8 profile, meaning you may introduce some banding. The available hardware values are still the same with the instructions from the OS-->gpu-->display being what changes.
 
Changing Gamma really just should make the displayed average color brighter.
Wouldn't really change anything for standard black text on white background.
Only for outside use when truly max brightness/readability is required there is another option. Set a cooler color tone. 8000k or higher. It those situations color accuracy doesn't matter anyway.
A normal white led emits colors which if they had free reign would release brighter blue than the remaining colors. Most properly calibrated screens are not as bright as in some default configuration.
To me subjectively the warmer color profile (which I greatly prefer indoors and at night) is some subjective 10% at least dimmer than the default cool color profile or an even cooler one. I would go to say it might be 15 difference at the max but I have no tool to measure that in actual nits. Only my eyes.
Maybe the difference between the top brightness setting and two down.

I would only use such a max bright color profile if I really need it to combat bright daylight.
Fortunately I still got one of the very bright 400 nit 2010 matte screens.

There is nothing like a driver hack as existed for the Asus EEE PCs that could simply overdrive the backlight. You can only use more backlight and not let the TFT dimm away too much brightness in the lower color spectrum.
