*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 the PT-LX351U, PT-LX321U, PT-LX271U and 1 280 x 800 for the PT- z
LW321U, PT-LW271U.  
A signal with a different resolution will be projected after converting the resolution to m\
atch the projector display.
When interlaced signals are connected, flicker may occur on the projected image. z
Even the above signals exist, some image signals that recorded in specia\
l method may not be displayed. z
The  operation may not optimize the image position or the resolution, depending on the input signal format or  z
the image contents. In this case, switch to a different image and execute  again.
When the detected signal is out of display range under PC source, the "O\
ut of display range" message will display on the  z
top left corner of the image.
