The default filename for the program’s installer is LCDtest-mac.zip. The following version: 2.0 is the most frequently downloaded one by the program users.
Most LCD monitors have a gamma setting that you can play with. Inaddition, the contrast setting can affect this test, but don’t changethe contrast so much that it fails the quickcontrast test.
The four bars at the left are the most important ones to get right. They represent a luminance that is 48% of the maximum. When the 48% setting iscorrect, you may wish to fiddle with other settings to get the bars for 25%and 10% to blend in at the 2.2 reading.Lcd Test For Mac Catalina
Don’t be upset if you can’t find a monitor setting that shows aconsistent gamma of 2.2 for all luminances. There are very fewmonitors which can do that without some form of color management inthe operating system. For photo editing, it is best to create an ICCmonitor profile tailored for your monitor with the help of a hardwarecalibrator, such as a Datacolor Spyder or an EZcolor Eye One, or maybeat least check the color rendering with for example a PantoneHuey. Apart from getting a better gamma response, you will also geta better color rendering with tools like this.BackgroundWhat it should look likeOn the right is what the gamma calibration test image should look like. Mac users
Note for Mac users: check your system gamma for this test; it’sunder Apple > System Preferences > Displays > Color > Calibrate >Gamma. If it is set to 1.8, of course the test should show a value1.8.Adjusting the video card driverAdjusting the video card LUT for an NVIDIA card in Windows.
Some video card drivers in Windows offer a possibility to manuallycompensate for a bad gamma characteristic of your monitor. See thescreenshot below: go to ’Display Properties’ > ’Settings’ (1) >’Advanced’ (2) > GeForce (if you have an NVIDIA Geforce, 3) > Colorcorrection (4) > Advanced mode (5). Then adjust the curves with yourmouse. It works best to first optimize the 48% image with a point at x=0.72(72% of the horizontal scale of the curve plot; the rightmost yellow line),then the point at x=0.53 for the 25% image, and finally the point at x=0.35for the 10% image.

Other gamma test images on the web will typically compare a 50% grey areawith a black-and-white pattern, rather than do it for several luminancelevels and individually for the red, green, and blue components. As you willprobably have seen, the check on a 50% grey level is not representative for thebehavior of your monitor over various grey levels and individual RGB colorcomponents. The reason for using 48% rather than 50% as a luminance is thatmany LCD screens have saturation issues in the last 5 percent of theirbrightness range that would distort the gamma measurement.
These PNG images are without embedded gamma information. I believe that thetest works, even in browsers with broken gamma support such as InternetExplorer 6 and 7. For more information about gamma (links open in new window):
