The practical answer

Use a dual-output HDMI 2.1 or DisplayPort 1.4 KVM and treat 4K144 as an end-to-end Display Stream Compression (DSC) requirement. The MacBook Pro needs two independent high-bandwidth display outputs, usually through suitable Thunderbolt adapters or a dock that exposes two native streams.

TESmart HDK202-M24

Published specifications do not prove the complete setup

What this means for you: The manufacturer states dual 4K144/160 via Display Stream Compression (DSC). Confirm the exact MacBook Pro chip, adapters, monitor timings and cable chain.

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 DKS202-M24

Published specifications do not prove the complete setup

What this means for you: The DisplayPort 1.4 route supports 4K144 via Display Stream Compression (DSC), but the Mac must expose two independent DP streams.

Product-specific limits
  • 4K144 or 165Hz may require Display Stream Compression (DSC); confirm the GPU, monitor, adapters and cables support it.
  • Each display requires its own host-side DisplayPort signal.
  • It does not charge a USB-C laptop.

Compatibility constraints

  • Two high-refresh displays require two complete video paths from each computer.
  • Display Stream Compression (DSC) support must exist at the GPU, adapter or dock, KVM and monitor.
  • variable refresh rate (VRR) and high dynamic range (HDR) should be tested at the target refresh, not only at 60Hz.

Recommended setup sequence

  1. Check the MacBook Pro model's external-display limits.
  2. Choose one connector standard for the full desk where possible.
  3. Use certified short cables rated for the required bandwidth.
  4. Test 4K144, high dynamic range (HDR), variable refresh rate (VRR) and wake behaviour on each host separately.
