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.

Note 1: In composite sync or sync-on-green signal, H sync signal must be inserted into V sync signal.

No good Good

Note 2: In H/V separation sync signal, V sync signal must not be included H sync signal or equalization pulse. Also, H sync signal must not included V sync signal and equalization pulse.
