defect.

The size of a circular area is defined by the average of the size along the horizontal axis (=a)
and the vertical axis (=b), i.e. D=(a+b)/2. The size of a lint/scratch is defined by its with (=W) and
its length (=L).

• Please be aware that the protective plate in front of this display is sensitive for scratching
during cleaning. This is caused by hard particles (like sand) that might be present in the cloth
used and/or the cleaning fluid.
• Small backlight intensity variations can occur in even colored backgrounds.
• Discoloration of the active area circumference can occur and should be treated as normal
and will not change the functional performance of the 3D intelligent display.
• Dimenco Displays is not responsible for a poor performance due to a not optimal signal input
and not complying to the following DVI standard: Digital Visual Interface DVI, Digital Display
Working Group, Revision 1.0; April 02, 1999.
