Functional Inspection
Keypad button - All keypad buttons must operate smoothly.
General - All OSD functions must be checked for functionality. When OSD menu is displayed, there shall be no visible peaking, ringing, streaking, or smearing artifacts on the screen.
Factory Default - The factory settings (with appropriate center, size, geometry distortion, etc.) shall be displayed upon “Recall” is selected
from OSD
Display Size - All preset modes shall expand to full screen size using OSD
Horizontal and Vertical Size controls
Display Data Channel (DDC) - The purpose of the DDC test is to verify the DDC1/DDC2B operation of the projector and to verify Plug & Play function. Acoustic - High pitch sound from cooling fan and color wheel is unacceptable.
