critic.

 The image offers few, but clear and important elements of evaluation and control.
1) White, black and 9 grey values must be clearly distinguishable; if not, adjust
   brightness and contrast.
2) Image borders and separation bars between colours must be clean without any curve and
   perpendicular; if not adjust the screen geometry. 
3) Each colour must be uniform and separation with the black borders must be clean. You
   can accept light vertical or horizontal lines inside the blue rectangle and/or other
   oblique ones inside the yellow rectangle.
4) All horizontal and vertical lines (upper-left and lower-right) bust be clearly 
   distinguishable and, between each line, the colour must be exactly as the background.
   The same must be for the smaller 6 lines group (3 horizontal and 3 vertical).
 We recommend to read carefully the monitor manual before each adjustment, overall 
paragraphs number 3 and 4.
