The display unit supports input of the following video signals: NTSC, PAL, and SECAM.
When the video cable is not connected to the display unit, or when the cable is connected but there is no video signal, the computer may not be able to connect to the display unit or connection may be possible but connection gets interrupted intermittently. Frequency of the above occurrence depends on the video signal.
