VESA DPM (Video Electronics Standards Association - Display Power
Management)
VESA specifications achieve increased energy efficiency for computer monitors. This involves
standardization of signals sent from the computer (graphics board).
DPM defines the status of signals transmitted between the computer and monitor.

The following table shows factory preset analog signal timing:
Attention
• Display position may be deviated depending on the PC connected, which may require screen adjustment using Setting
