Quote from site:
It is hard to select a good LCD screen based on the specifications such as
viewing angle and contrast, since different manufacturers have different
opinions on how to measure these. I made these test patterns in order to check
out a few monitors in the shops before I purchased one. You can check the images
on this webpage or put them on a usb stick and try them in the computer store
like I did. If you are already stuck with your monitor, you can use this page to
adjust its contrast and brightness settings, or to show off how good (or bad)
your monitor is compared to those of your friends. With these test images are
much more revealing regarding monitor shortcomings than ordinary photographs and you can judge the monitor quality by eye.
