Video control
Use these commands to change the projector's video output controls. The range of values used
for these commands should match the range displayed in the on-screen display (OSD). The
firmware must handle videofreeze and videomute states correctly. A change should be made to
ensure that videofreeze and videomute are mutually exclusive.
