Configuration guide

Dual 4K monitors + webcam + USB audio

A peripheral-heavy dual 4K desk where USB bandwidth matters as much as the video specification.

The practical answer

Choose a KVM with confirmed USB 3.x rather than a keyboard-and-mouse-only USB 2.0 hub. The HDK202-M24 provides headroom for mixed HDMI and DisplayPort computers; HKS202-M24 is cleaner for an all-HDMI desk.

Product assessments

These statuses apply to this exact configuration, not to the product in every possible setup.

Compatible

TESmart HDK202-M24

Compatible based on published specifications

What this means for you: Dual 4K60 is well within its video capability and USB 3.x is available for the webcam and audio interface.

High dynamic range (HDR): supported · Variable refresh (VRR): supported · Keeps monitor settings (EDID): supported

Product-specific limits
  • 4K240 and dual 4K144 are Display Stream Compression (DSC) modes, so every device and cable in the signal chain must support the required mode.
  • A Mac needs a separate video output for each display.
  • It does not charge a USB-C laptop.

TESmart HKS202-M24

Compatible based on published specifications

What this means for you: A straightforward all-HDMI choice with USB 3.x, monitor-setting retention (EDID) and ample 4K60 headroom.

High dynamic range (HDR): supported · Variable refresh (VRR): supported · Keeps monitor settings (EDID): supported

Product-specific limits
  • Dual 4K above 120Hz depends on Display Stream Compression (DSC) and the complete GPU, monitor and cable chain.
  • A Mac needs a separate video output for each display.
  • It does not charge a USB-C laptop.
Compatible with limitations

AV Access iDock C10

Compatible with stated limitations

What this means for you: Suitable for a USB-C laptop and desktop at dual 4K60, but a Mac on the Multi-Stream Transport (MST) path may mirror the displays.

High dynamic range (HDR): not confirmed · Variable refresh (VRR): not confirmed · Keeps monitor settings (EDID): supported

Product-specific limits
  • Most Macs mirror two displays on the single-cable Multi-Stream Transport (MST) path rather than extending them.
  • 3440×1440 is limited to 60Hz and a 5120×1440 display falls back to 3840×1080.
  • Power delivery is up to 60W.
  • high dynamic range (HDR) and variable refresh support are not confirmed in the published specification.

Compatibility constraints

  • High-resolution webcams can saturate a shared USB link when combined with storage or capture devices.
  • Some USB audio devices dislike being rapidly disconnected during switching.
  • Mac dual-display behaviour still depends on the selected host topology.

Recommended setup sequence

  1. Verify dual 4K60 video first.
  2. Connect the audio interface and test switching without the webcam.
  3. Add the webcam at its intended resolution and frame rate.
  4. Check wake, microphone selection and audio-device recovery on both computers.
