Explore the Screen
Look at the gray background to estimate the image persistence.
Explore with Motion
Watch for horizontal moving of the vertical line to estimate the nonuniformity of the screen.
Take a Picture
Take a picture of the monitor screen using a phone or a digital camera in a dark room.
By using the focus targets on the screen, you can properly set focus of your camera.
In most cases, you will probably be using shutter speeds of a second or slower.
At slower shutter speeds, you certainly need a tripod or image stabilization to produce sharp images.
Analyze the Picture
After the picture was taken, you should analyze it.
Use the Contrast level slider to adjust visibility of details.
As an example, try to analyze this picture (ISO 100, f/4.0, 5s).
The values of 20, 40 and 60 are duration of the test in minutes.
You will see the test grid, which will be dynamically switching.
The first column will be always static.
Look away during the test so that your eyes were not tired at the end.
After the test, screens with image persistence will show a faint impression of the grid on the gray background.
Note: Image Persistence Detector will not work during the test.
When you hide the controls, the program will count the spent time as a successfully used for selected removal method.
