(via recenseo) This applied to me. Updating my profile seemed to make everything a little bit nicer:
When I first got my Macbook Air, I was surprised how extrememly bright the screen was. It was crisp and beautiful, but in my honest opinion it was a bit too bright.
However, the brightness wasn’t the only annoyment about my screen. Most pictures looked “flat”, and somehow I couldn’t really identify the difference between a white background and a textured white background. The contrast was too low and colors weren’t “alive” enough.
Reading a post on Mac1.no I learned somethign that explained my concerns: The Macbook Airs ship with two different screens; One made by Samsung and one made by LG.
The one made by Samsung has the perfect settings from the very beginning, but for some reason the LG doesn’t. To make the LG version look similarly as good as the Samsung screen, you’ll have to follow a couple quick steps.
First of all, to learn what type of screen you have (Samsung or LG), you simply have to paste this line into the Terminal:
ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6
Now, if you get a respons that starts with LTH, you can forget about this post and live on. However, if it starts with LP, this might just make your day.
Go ahead and download this file from MacRumors. Next step is to navigate to Macintosh/Library/ColorSync/Profiles/Displays. Move the file you just downloaded in here.
Open System Preferences, and go to the “Screens” panel. Switch to the “Colors” tab and uncheck the box that says “Only show colors for this display” (This may not be the correct name, as I’m simply guessing based on my own translation from Norwegian. They should however mean the same, so if you put some will into it, you’ll find the right button).
If you haven’t already changed your settings, “Color-LCD” will be the default color setting. As you ay have noticed, beneath the default setting there shall have appeared some extra options. One of these should say “Color-LCD”, just like the default one. Select it, and enjoy.
You should notice that apps like Twitterrific, iA Writer, Reeder and your desktop picture will look twice as good as before. Even the dock and Finder will look better.
