Frequently Asked Questions

Can the CKL-922HUA extend my desktop across two monitors for both computers?

Yes, if each computer or laptop has two video outputs and supports extended display. The CKL-922HUA switches both monitors, the keyboard and the mouse between the two machines.

Does it work with a laptop that has only one HDMI port?

Only if the laptop has a second video output, such as DisplayPort, VGA or DVI, and you use a reliable adapter (not included). CKL suggests checking first by connecting the laptop directly to two monitors.

What resolution and refresh rate does this KVM switch support?

The CKL-922HUA is rated for 4K at 30Hz. For higher refresh rates at 4K, check the product listing or look at a switch rated for 60Hz.

How do I switch between the two computers?

There are five ways: mouse scroll-wheel clicks, keyboard hotkeys, the push button, auto scan and a wired remote.

What cables come in the box?

Two sets marked A and B. Cable A has USB and HDMI (plus optional audio jacks) on the computer end and a single HDMI on the other, which goes into the IN A port. Cable B is a standard HDMI cable for the IN B port so HDMI Out B works.
