•If a vertical and horizontal frequency-select mode exists, select 60Hz (vertical) and 31.5KHz (horizontal). In some cases, abnormal signals (such as stripes) might appear on the screen when the PC power is turned off (or if the PC is disconnected). If this happens, press the INPUT button to enter the video mode. Also, make sure that the PC is connected.
•When horizontal synchronous signals seem irregular in RGB mode, check PC power saving mode or cable connections.
•The display settings table complies to the IBM/VESA standards, and based on the analog input.
