Notes on the PC mode
• This unit does not support XGA mode (1,024 × 768) and above. If you set the vertical frequency to 60
Hz in XGA mode, the picture is displayed but the picture quality is poor due to the signal loss.
Change the screen resolution on your PC to SVGA or VGA.
•Though the Personal LCD Display supports the signals listed above, set the vertical frequency to 60
Hz when using with SVGA (800 × 600), or to 72 Hz or 75 Hz with VGA (640 × 480) mode. Also adjust
the vertical frequency of the external display output signal of the connected computer.
• When you display VGA pictures (640 × 480) or NTSC video pictures (video mode), the pictures are
not displayed across the entire screen. About 60% of the screen area is utilized.
• Some notebook type PCs do not output the RGB signal in the adjusted screen resolution and the
vertical frequency from the external monitor port until you set the PC to external display mode.
