Monitor Test
It is always a good idea to test the computer monitor from time to time, especially after installing new video card drivers, operating systems or purchasing a new one. Monitor Test is actually a name of an application that assists you in testing a computer monitor.
It was mentioned at the New Morning site which had a short article about it and a link to the developer's website.
Monitor Test is a portable application which makes it a handy tool to include on an USB drive that is filled with all kind of tech support tools for troubleshooting, configuration and customization of PCs running Windows.
Once executed the application starts in full screen mode showing all the tests that can be performed. Each test can be selected with a left-click of the computer mouse. The utility offers a wide variety of monitor tests like colors, gradients, geometry, speed and text tests.
As you can see, there is lots to test and explore. Some monitor tests span across several screens which you can switch between with a left-click of the mouse.
Monitor tests works well with aspect ratios of 16:9, 16:10 wide screen monitors and 4:3 monitors. No information about operating system compatibility is available on the author's website. Monitor Test runs fine on Windows XP and newer versions of Windows.
Update: The program is no longer available, the website simply returns a blank page where the program was hosted on previously.

To provide you with one example: the Online Monitor Test provides you with an online tool that you can run right in your browser to calibrate the monitor. Or, if you prefer that, you can download it to your local system to run it from there provided that you are using Microsoft Windows as the operating system.
Just run the test and use the controls on your monitor or the software driver to change the monitor's brightness, contrast and other values.
