*1: “i” added to the resolution value indicates an interlaced signal.
*2: HDMI signal of 480i and 576i is only supported by 27MHz Dot clock signal.
*3:  Where marked "o" signals indicates in Plug and Play is compatible with EDID of projector. Unmarked signals in Plug and 
Play may also be compliant if input terminals are written in the format list. Where Plug and Play is unmarked and nothing is 
written in the format list, difficulties in projecting image may occur even when computer and projector appear to have same 
resolution.
Note
The number of display dots is 1 024 x 768 for PT-TX301R and 1 280 x 800 for PT-TW331R. 
 
A signal with a different resolution will be projected after converting the resolution to match the projector display.
When interlaced signals are connected, flicker may occur on the projected image.
 
Even the above signals exist, some image signals that recorded in special method may not be displayed.
 
The <AUTO ADJ.> operation may not optimize the image position or the resolution, depending on the input signal format or 
 
the image contents. In this case, switch to a different image and execute <AUTO ADJ.> again.
When the detected signal is out of display range under PC source, the "Out of display range" message will display on the 
 
top left corner of the image.
