Mac + PC + 5120×2160 5K2K ultrawide

Why a 5K2K ultrawide needs an exact resolution check instead of a generic 4K or 8K label.

The practical answer

No current catalogue product explicitly guarantees 5120×2160. A headline 8K capability does not prove this ultrawide timing. Use direct manufacturer confirmation for the exact monitor model, refresh, colour depth and Display Stream Compression (DSC) path before purchase.

Product assessments

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

Needs verification

TESmart DKS202-M24

Published specifications do not prove the complete setup

What this means for you: The DisplayPort 1.4 and Display Stream Compression (DSC) bandwidth may be sufficient, but 5120×2160 is not explicitly stated on the current product page.

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.

TESmart HDK202-M24

Published specifications do not prove the complete setup

What this means for you: The hybrid HDMI 2.1/DisplayPort 1.4 model lists several ultrawide timings, but not 5120×2160.

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.

Compatibility constraints

5120×2160 is not the same timing as 5120×1440 or 7680×4320.
The Mac adapter or dock must expose the exact timing before the KVM can pass it.
high dynamic range (HDR) and higher colour depth increase bandwidth further.

Recommended setup sequence

Record the monitor model, target refresh, colour depth and preferred input.
Verify the exact mode directly from both computers.
Ask the KVM manufacturer to confirm that timing in writing.
Retain a return route in case monitor-setting retention (EDID) negotiation fails.
