Thank you for your understanding.

You can use this test to test a monitor for color vividness and dead/hot pixels of your LCD. The program can also be used to detect an LCD defect - specific colour dominance of the entire display.

Program shows 11 screens:

• Full red, full green and full blue
  
• Full yellow (composed color out of red and green)
  
• Full magenta (composed out of red and blue)
  
• Full cyan (out of green and blue)
  
• Full white and full black
  
• Pixel chessboard out of black and white pixels
  
• Chessboard out of cyan and red pixels
  
• Chessboard out of blue and yellow pixels.
  

The three chessboards are designed to shift the lightness of sub pixels. All three chessboards should look grey or as close to grey as possible. If you see the dominating color in any of these screens, then that color is also the dominating color of the entire display (either the settings are wrong or the display is of bad quality).

While watching the chessboard displays, you can press the "A" key to toggle pixel animation. This will invert the chessboard once a second. You should see swift flickers. The swifter the flickers are, the less response time the display has. Flickers can be white or black. If they are white, the display has some Response Time Accelerating (RTA) technology turned on.

You can advance tests with a Space key and you exit the program with the ESC key.
