OPERATION NOTES

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE GEFEN 4X1 DVI KVM DL/SL SWITCHER

• The 4x1 DVI KVM DL/SL Switcher will take any of up to four (4) DVI dual-

link or single-link resolution inputs and switch them, one at a time, to a DVI

output device such as a display/monitor or projector. Resolutions can be up

to 3840x2400.

• The 4x1 DVI KVM DL/SL Switcher is housed in a metal box for better RF

shielding.

• Computers must be turned on one at a time and the switcher must

be selected to the computer that is booting up. This is so that monitor

information (EDID) can be transmitted from the display to each computer.

After one computer completes the startup process, you can boot up the

second computer and repeat the process with the remaining computers.

This can be avoided with the use of the LOCAL EDID mode (page 11) that

will constantly supply each computer with an EDID. In this scenario, an

EDID stored in the local memory location, or user uploaded EDID, is

supplied to each input for use by the connected source device. Then, each

computer can boot up in any order and at anytime, regardless of which

computer the switch is selected to.
