Problem

Solution

 

 

 

Video image is unsatisfactory.

•

Adjust display settings (see

 

 

page 19).

 

•

Try reducing the refresh rate of your

 

 

graphic card’s output.

 

•

For monitors with KVM extender

 

 

option:

 

 

• Adjust focus and/or brightness

 

 

dials on the remote unit of the

 

 

KVM extender.

 

 

• Consider adjusting KVM extender

 

 

cable-length jumpers (see page

 

 

57).

 

 

• Refer to the “video” section of the

 

 

troubleshooting chapter in the

 

 

KVM extender manufacturer’s

 

 

manual.*

 

 

 

No video image.

•

Make sure that the monitor is powered

 

 

up. Listen for the sound of a fan.

 

•

Check the video extension cables

 

 

(and, for units with the KVM extender

 

 

option, check the CAT5 interconnect

 

 

cable) to be sure that all connectors

 

 

are properly and securely attached.

 

•

Make sure that the host computer’s

 

 

monitor resolution is set for no higher

 

 

than 1024 x 768.

*Note: References to “serial device” in the KVM manufacturer’s manual denote the “touch screen” of the ET 350 monitor.
