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.

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.

8 recorded claims are manufacturer-confirmed, 1 are conservative inferences and 0 remain unresolved. Product evidence last checked 12 August 2026.

Needs verification

TESmart HKS202-M24

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
  • Single 4K240 and dual 4K above 120Hz depend on Display Stream Compression (DSC) and the complete GPU, monitor and cable chain.
  • The manufacturer lists 3440×1440 up to 144Hz and 5120×1440 up to 120Hz on a single output.
  • A Mac needs a separate video output for each display.
  • It does not charge a USB-C laptop.
Evidence behind this assessment

7 recorded claims are manufacturer-confirmed, 1 are conservative inferences and 0 remain unresolved. Product evidence last checked 22 August 2026.

Do not treat this as a purchase verdict. Confirm the unresolved host, adapter, cable and display path first.

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.

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

Product-specific limits
  • Single 4K240 and dual 4K144 require Display Stream Compression (DSC); confirm the GPU, monitor, adapters and cables support the target mode.
  • The manufacturer lists 3440×1440 up to 144Hz and 5120×1440 up to 120Hz, so 3440×1440 at 165Hz is above the published limit.
  • Each display requires its own host-side DisplayPort signal.
  • It does not charge a USB-C laptop.

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.

Technical term unclear? See KVM terms explained for plain-English definitions and practical consequences. Compare the current 4K and ultrawide KVM timing evidence before relying on a headline resolution.
