44 Input Mode
• Check your PC instruction book for information about connecting your PC to a display.
• 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 so, 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.
• The DVI support mode is regarded as same to the PC support mode.
• The best timing for the vertical frequency to each mode is 60Hz.
