Triple-Monitor KVM for Four Computers

The Vszerda CKS-NO DKM403B-USB3.0-F lets a single keyboard, mouse and three displays control four separate PCs or laptops. Each connected system must provide two DisplayPort and one HDMI video output to match the switch inputs. It suits users who need simultaneous extended or mirrored desktops across three screens without unplugging cables. Builders whose machines lack the required triple-video ports cannot use this unit.

Bundled Cables, Power Adapter and Wired Remote

The package includes four USB 3.0 cables for upstream links, a 5-volt power adapter and a push-button wired selector for manual switching. HDMI and DisplayPort cables are not supplied, so they must be sourced separately. The front panel also adds three USB 3.0 ports plus microphone and audio jacks for shared peripherals. No driver disc or management software is mentioned in the supplied data.

Port Mapping Must Match Exactly

Installation follows a strict port-to-port scheme: HDMI IN1A, DP IN1B, DP IN1C and USB IN1 belong to PC1, and the same pattern repeats for PC2 through PC4. Mixed insertion is not supported and is the most common cause of only one video output appearing. The unit weighs .99 kilograms and draws power from the included adapter. If the switch behaves unexpectedly, the supplier advises cycling the power switch off and on.

Questions about this item

Will the power adapter or the USB 3.0 cables need replacing after extended use?

The unit ships with a 5 volt power adapter and four USB 3.0 cables; no user-serviceable parts are listed, so only the external cables or adapter would ever need swapping.

What resolution ceiling appears first when all three monitors run at high refresh rates?

The switch tops out at 8K@60Hz across its two DisplayPort 1.4 and one HDMI 2.1 outputs, provided each computer and monitor also supports that mode.

How much heat or fan noise does the CKS-NO produce during all-day operation?

No active cooling is mentioned and the unit weighs .99 kilograms, suggesting passive operation with minimal audible noise or heat buildup.
