What this KVM switch does

The Vszerda ZY-ASW221 lets you share two monitors and USB 3.0 peripherals between two computers over HDMI 2.1 connections. It supports 8K at 60 Hz and 4K at 120 Hz for high-refresh gaming or colour-critical work. Certified to CE, FCC and RoHS, it arrives new in a carton box. It is not for setups that need more than two video sources or more than two displays.

Thermals noise and power

The unit is non-shielded and uses a 1 mm outer-diameter cable construction with male-to-male connectors. It draws power from the attached hosts so no external adapter is required. Passive operation means zero fan noise and no added heat in normal use. It is not for environments that demand shielded cabling for EMI-sensitive equipment.

Build fit and cabling

HDMI 2.1, DisplayPort, Mini DisplayPort and USB interfaces are all present on both connector ends, giving wide host and monitor compatibility. The 1 mm cable diameter eases routing in tight cable-management channels. The switch frees up desk space by consolidating two workstations into one keyboard, mouse and dual-monitor station. It is not for installations that require longer runs than the supplied cable length allows.

Questions about this item

How do I connect the Vszerda ZY-ASW221 to two monitors and two computers without losing 8K 60Hz or 4K 120Hz?

Plug each computer into its own HDMI 2.1 input, then connect both monitors to the two HDMI outputs; use the front button or hot-key to switch — do not swap cables while powered on or the EDID handshake can drop to a lower mode.

Which parts of the ZY-ASW221 wear out and need replacement first?

The mechanical push-button and the USB 3.0 ports see the most cycles; keep the switch dust-free and avoid yanking cables to extend their life.

At what point does the ZY-ASW221 hit its bandwidth ceiling during a long gaming session?

The HDMI 2.1 link caps at 8K 60 Hz or 4K 120 Hz; sustained HDR at those rates will saturate the path before any thermal limit appears.
