Setting up your iMac monitor.

I get headaches browsing the net with my new iMac. I think it is too bright but cannot find where to adjust it. Any clues?
Go to System Preferences > Displays and you'll find a Brightness slider.
If you want to calibrate your iMac's monitor to a particular color temperature, or set up a Colorsync profile for it, stay in the Displays preference panel (or "pref pane," as we call it in the Mac world) and click the "Color" tab at the top. You'll see a list of display profiles down the left side.
To make your own profile, click the "Calibrate..." button on the right side.
Mega Tip: After the Display Calibrator Assistant appears, check the Expert Mode checkbox in the lower left corner. Using Expert Mode takes longer, but gives you a more accurate calibration. In fact, I feel Expert Mode calibration is as accurate as, or maybe even more accurate than, a hardware calibrator -- because it's based on comparing the neutrality of color samples, and the eye is a very accurate comparator.
The Display Calibrator Assistant will walk you through the process of profiling the monitor, choosing a gamma (1.8 is the default for Mac graphics), and selecting a color temperature. Do this after the monitor has been on for at least 20 minutes so the backlight will be warmed up, under lighting conditions typical of your computer use. You might even want to do separate "daytime" and "evening" calibrations to cover the different ambient light levels in your computer room, then choose the appropriate one whenever you're going to do any color-critical computer work.
Final note: If you previously had a CRT monitor, your iMac's monitor may give you eyestrain at first simply because it's quite a bit sharper, and your eye struggles to focus on all that detail. You'll get used to it after a few days; in fact, overall it's more relaxing to view because it doesn't have that vertical-scan flicker that CRT monitors have.
