Gamma Value Monitor Check - Here's a quick method for checking the gamma value of your LCD monitor.
You need to view the following image on your monitor's screen but position yourself slightly back from the monitor then, while looking directly at the image, half-close your eyes. We're not saying this test is 100% accurate, but you will be able to roughly see what gamma value your monitor is currently configured to.
You need to visually compare the square outlines and the stripes around them, looking for patterns that appear to have the same tone of gray (brightness). The pattern for which the square frame and the striped pattern around it appear closest in brightness represents the rough gamma value of your monitor.
If you look at the 2.2 square and the frame appears dark, the LCD monitor's gamma value is low. If the square frame appears bright, the gamma value is high.
For more monitor tests you can carry out, take a look at the technique section.
