Mixed DisplayPort 1.4 + HDMI 2.1 KVM setup

How to avoid adapter and feature loss when one computer or monitor path is DisplayPort 1.4 and the other is HDMI 2.1.

The practical answer

Prefer a KVM with native mixed connector support instead of converting every leg. The HDK202-M24 provides HDMI 2.1 and DisplayPort 1.4 per host and is designed for high-refresh high dynamic range (HDR)/variable refresh rate (VRR) paths. Confirm its physical port map against both computers and monitors before ordering.

Compatible with limitations

TESmart HDK202-M24

Compatible with stated limitations

What this means for you: It natively combines HDMI 2.1 and DisplayPort 1.4 with monitor-setting retention (EDID), high dynamic range (HDR) and variable refresh rate (VRR), but the exact input/output map and Display Stream Compression (DSC) mode must match the desk.

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.

Published specifications do not prove the complete setup

What this means for you: An all-HDMI KVM can work only with active DP-to-HDMI conversion that preserves the required refresh and features.

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.

TESmart DKS202-M24

Published specifications do not prove the complete setup

What this means for you: An all-DP KVM can work only with active HDMI-to-DP conversion, which is less common and often feature-limited.

Compatibility constraints

  • DisplayPort-to-HDMI and HDMI-to-DisplayPort are different conversion directions.
  • Passive adapters do not provide every high-bandwidth conversion.
  • Converters can remove variable refresh rate (VRR), high dynamic range (HDR), monitor-setting retention (EDID) or Display Stream Compression (DSC) even when resolution still works.

Recommended setup sequence

  1. Draw every host-to-KVM and KVM-to-monitor connector.
  2. Minimise active conversion and keep its direction explicit.
  3. Confirm the exact high-refresh timing in the KVM and adapter specifications.
  4. Test high dynamic range (HDR), variable refresh rate (VRR) and wake behaviour on both hosts.
