Connecting PC
- To enjoy vivid picture and sound, connect a PC to the Monitor.
- Avoid keeping a fixed image on the monitor’s screen for a long period of time. The fixed image may become permanently imprint-
ed on the screen; use a screen saver when possible.
- Connect PC to the RGB INPUT or DVI INPUT port of the Monitor; change the resolution output of PC accordingly.
- There might be a noise according to some resolution, vertical pattern, contrast or brightness in PC mode. Then change the PC
mode into other resolution or change the refresh rate into other rate or adjust the brightness and contrast on the menu until the
picture is clean. If the refresh rate of the PC graphic card can not be changed, change the PC graphic card or consult it to the
manufacturer of the PC graphic card.
- The synchronization input form for Horizontal and Vertical frequencies is separate.
