1. VGA ripple (1280x800):
Some certain PC sometimes can find slight
ripple noise in Bliss wallpaper.
� Waived by below reasons.
a. No any projector can ensure that it can be 100� no NB/PC compatibility issue.
b. ML300 major application is using on NB, we found only 3 NB sometimes can see the 1280x800
noise issue on 2� different NB test.
c. This issue only happened on 1280x800 mode of special pattern. if user occasionally found
noise, we can guide him/her to change to 1280x7�8 or 1280x720 mode.
