The practical answer

The TKS202-X4 is the current Thunderbolt-oriented match, especially for Apple Studio Display or dual 4K60 workflows. It is not a universal two-computer Thunderbolt dock: the Windows side and display connections must match its specific Thunderbolt and HDMI topology.

Compatible with limitations

TESmart TKS202-X4

Compatible with stated limitations

What this means for you: Designed for compatible Thunderbolt or validated USB4 hosts and supported Thunderbolt displays, with two Thunderbolt display outputs and 60W charging per compatible host. Verify the Windows PC and both displays against the current support list.

Product-specific limits
  • This model is primarily designed for Apple Studio Display and selected Thunderbolt displays; standard USB-C displays are not guaranteed.
  • HDMI or DisplayPort monitors require compatible third-party USB-C video adapters, and the manufacturer says stability can vary.
  • A USB-C connector alone does not establish compatibility; the host needs compatible Thunderbolt or validated USB4 capability.
  • The manufacturer states that actual resolution and refresh depend on the computers, displays, cables and system configuration.
  • Charging is limited to 60W per compatible computer.
  • TESmart states that Intel Thunderbolt certification is still in progress.
  • high dynamic range (HDR) and variable refresh support are not confirmed in the published specification.

Product-specific limits
  • Native dual extended displays use two USB-C ports on a supported MacBook.
  • The Mac itself must support two external displays in the intended mode; the KVM cannot create a second native display stream.
  • 3440×1440 is limited to 60Hz and a 5120×1440 display falls back to 3840×1080.
  • The Windows host still needs suitable display outputs for both monitors.
  • high dynamic range (HDR) and variable refresh support are not confirmed in the published specification.

Not compatible

TESmart HDC202-P23

Not supported by published specifications

What this means for you: Its USB-C laptop path relies on Multi-Stream Transport (MST), which does not provide two extended displays on macOS.

Product-specific limits
  • Windows can use the single-cable Multi-Stream Transport (MST) path; macOS requires two USB-C host connections for two independent extended displays.
  • The Mac itself must natively support two external displays; the KVM cannot bypass the computer display-count limit.
  • Laptop charging is up to 60W through Input A; the second Mac USB-C connection is used for the additional display signal.
  • 4K output is limited to 60Hz.
  • high dynamic range (HDR) and variable refresh support are not confirmed in the published specification.

Compatibility constraints

  • Thunderbolt compatibility does not mean every port arrangement is symmetric between the Mac and PC.
  • The TKS202-X4's dual-display high-resolution modes and 60W charging have specific limits.
  • Windows desktops without Thunderbolt need the exact alternate video inputs required by the KVM.

Recommended setup sequence

  1. Identify the Mac, Windows and monitor port map before choosing the KVM.
  2. Confirm whether the Windows host has Thunderbolt, USB-C DP Alt Mode or separate HDMI outputs.
  3. Match the display type and target refresh to the stated dual-display mode.
  4. Test charging, wake, USB devices and monitor detection on both hosts.
