This unit uses a DMD
TM
chip for the picture display. Their highly accurate technology makes it possible to keep more than 99.99% of
effective pixels, however, unexpectedly it can produce less than 0.01% of ineffective pixels. In such a case, missing or flashing of a
few pixels can be found on the screen. These are characteristics of DMD
TM
, not mechanical problems.
