3.4 Computer resolution does not match the monitor’s
• Verify if the monitor works fine if directly connected to the computer.
• Turn off the computer, wait few seconds then restart. During startup,
the computer will try to obtain EDID information about the monitor.
Make sure the monitor and KVM switch are ON and running before
restarting the computer.
• The switch will dynamically detect and copy the EDID information
from the monitor attached to the LOCAL console port. That
information will feed to the host computer during startup.
• The recommended Power ON sequence is as follows: monitor, KVM
Switch, finally the computers.
3.5 Video is fuzzy or unclear
• Verify if the VGA connector is firmly connected.
• If using the remote console extender, make sure to use high quality
cables free from defects.
