SV211HDUA4K: share one keyboard, mouse and HDMI screen

The SV211HDUA4K shares one display and peripheral set between two computers that each provide HDMI and USB. Its pushbutton works independently of the OS; optional hotkeys/software have separate OS requirements.

Applies to: Exact StarTech SV211HDUA4K; target up to 3840×2160 at 60Hz; USB 2.0 peripheral path.

video
Computer A HDMI + Computer B HDMI → KVM → one HDMI display
data
Each computer USB → KVM → keyboard/mouse USB; selected host owns the peripherals.
power
USB bus-powered KVM; no laptop charging path documented.
Functional path diagram. Arrows show the stated role and direction; they do not report an observed connection.

What the path requires

  • HDMI and USB outputs from each host; one compatible HDMI display.
  • Use integrated host cables; connect both functions for each host.
  • Use pushbutton if optional switching software is unavailable for the OS.

Video rate and USB rate are separate

The datasheet lists 4K60 video and USB 2.0 480Mbps. Neither says this KVM is suitable for a 10Gbps SSD, 4K capture device or every advanced keyboard feature.

Worked documentary examples

Switching an in-use storage device

Documented outcome: Preserve data first

  • USB storage attached to the selected host.
  1. Finish writes and eject from the current OS before switching.
  2. Do not use the switch as a recovery action for an active copy.

Your next useful observation

Confirm both hosts have separate video and USB connections and that the target display mode is offered.

Keep these limits

  • Exact host/display feature combinations not hardware tested.
  • HDR, VRR, charging and gaming-peripheral extensions are not established here.
