MacBook Pro + 4K240 monitor

Whether a KVM can preserve a 4K240 monitor path from a MacBook Pro and a second computer.

Main riskMac 4K240 output support

The practical answer

Only the HDK202-M24 explicitly states 4K240 via Display Stream Compression (DSC) in the current catalogue. That makes it the candidate, not a guaranteed match. The exact MacBook Pro generation, USB-C or HDMI output, adapter, monitor firmware and cable chain must all expose the same 4K240 mode.

Product assessments

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

Needs verification

TESmart HDK202-M24

Published specifications do not prove the complete setup

What this means for you: The KVM states 4K240 via Display Stream Compression (DSC) with high dynamic range (HDR) and variable refresh rate (VRR), but the MacBook Pro path must independently prove that exact mode.

Displays: 2
Video connections: HDMI 2.1 / DisplayPort 1.4
Published 4K ceiling: Single 240Hz · multi 144Hz
USB-C laptop charging: None

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.

Not compatible

TESmart DKS202-M24

Not supported by published specifications

What this means for you: Its stated 4K ceiling is below 240Hz.

Displays: 2
Video connections: DisplayPort 1.4
Published 4K ceiling: Single 165Hz · multi 144Hz
USB-C laptop charging: None

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

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

Many MacBook Pro models and adapters do not expose 4K240 even when the monitor and KVM can.
Display Stream Compression (DSC), colour depth, high dynamic range (HDR) and variable refresh rate (VRR) are part of the same bandwidth budget.
A dual-monitor KVM can be used with one display, but it does not remove the single-display verification requirement.

Recommended setup sequence

Prove 4K240 directly from the MacBook Pro to the monitor.
Record the working cable, adapter and display settings.
Insert the HDK202-M24 without changing those settings.
Repeat high dynamic range (HDR), variable refresh rate (VRR), sleep and wake tests on both computers.
