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.
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
When the detected signal is out of display range under PC source, the "Out of display range" message will display on the
