Test the screen color:
The circles should be complete and round.
If you don't see the circle, adjust your screen resolution.
Check if there are any defective pixels on the screen. All pixels must be black. If you see a colored illuminated pixel, this indicates that the subpixel is continuously illuminated.
Check if there are any defective pixels on the screen. All pixels must be white. If you see a black pixel, this indicates a missing pixel.
Check if there are any defective pixels on the screen. All pixels must be red. If you see a black pixel, this indicates a red subpixel is missing.
Check if there are any defective pixels on the screen. All pixels must be green. If you see a black pixel, this indicates a green subpixel is missing.
Check if there are any defective pixels on the screen. All pixels must be blue. If you see a black pixel, this indicates a missing blue subpixel.
All pixels must be cyan.
All pixels must be magenta.
All pixels must be yellow.
Evaluate image uniformity using different grayscales. Brightness must be evenly distributed across the entire image, and the image must not have any colored areas.
Test how well your monitor can display similar colors while preserving the differences between them. You can create two color patches to do so. The more similar two colors are but still distinguishable from each other, the better your display can distinguish between the colors. This test is also great for visual comparisons between two different displays.
Select a larger viewing distance to test the gradient display. The grayscale image must be reproduced in total view without any unnecessary coloration and with a uniform gradient, and at 256 intervals, must not have any noticeable sudden changes Any idea about the brightness between individual grayscales? At smaller distances, the corresponding bars should be clearly distinguishable from each other.
This test allows you to determine whether your monitor can reproduce text sharply and without any shadows, independently of other influences, such as text smoothing.
Check the stability of the monitor's viewing angle. As you increase the viewing angle, the size and shape of the displayed circles will remain roughly the same. Small changes may appear. Less is better.
Determine the gamma value of your screen.
Use the slider to change the grayscale of the logo until it blends into the background to the greatest extent possible. The displayed value corresponds to the gamma value of your screen.
This test is mainly used to compare the response times of two monitors.
Start by choosing a speed that creates clear streaks on the rectangle. However, you can still clearly trace the rectangles visually. Then change the distance between the rectangles until the bottom edge (streak) of the right shape no longer overlaps the bottom edge of the left shape. The smaller the distance, the shorter the response time. When comparing multiple monitors, choose the same speed. You can also use this test to see the impact of different settings on your display, such as acceleration, refresh rate, and blur reduction.
