At the very bottom of Focus-Online's homepage is a "gamma check" image. It's a quick, but crude way to check and see if you have your brightness/ contrast set somewhat correctly: Focus-Online
As a side note. Sometimes the daylight and artificial light in your computer room has a great effect on the monitor. At nightime, go to a nice photo page and view it with your lights on. While you are viewing the monitor, turn off the lights. If the photo "comes to life" with the lights off, that means you are probably getting light polution or glare from your fixtures. Kind of like trying to count the stars in the sky from downtown Manhattan. Try moving the monitor or lights themselves (other than a ceiling fixture, of course) to reduce it. I usually keep the lights down low, with just a task light on the desk turned on when I surf alot. It still gives me plenty of light, but I can locate the fixture in an optimum place for reducing the polution. It can make a huge difference sometimes.
