• This projector may not be able to display images from notebook computers in simultaneous (CRT/LCD) mode. Should this
occur, turn off the LCD display on the notebook computer and output the display data in “CRT only” mode. Details on how
to change display modes can be found in your notebook computer’s operation manual.
The following is a list of compatible VESA standards. Please note that this projector also accepts signals outside
of the VESA standards.
• Depending on the mode selected, the projector may clearly display images under 100 Hz.
