ACCEPTABLE SIGNAL TYPE
The following are acceptable input signal types.
Projection unit automatically distinguishes mode according to frequency of input signal. All the signals
accepted are displayed on screen with 1024x768 dot by internal resolution converter.
The Digital Signal Link function may not support NTSC/PAL/SECAM signal supplied from RGB-1 and RGB-2
input terminal. Also, Digital Signal Link function may not support unstable signal either.
