4 Port Dual Monitor KVM Switch Kit HDMI 4K60Hz with USB 3.0 Docking Station, EDID: Complete Review

TESmart HKS402-P24 Review — Worth it for Multi-Computer Dual-Monitor Setups?

Introduction — the problem it solves

If you juggle multiple computers (developer rigs, a work desktop, a personal machine, and perhaps a small server) while using two high-resolution monitors, you know the pain: tangled cables, constant re-plugging, and inconsistent display behavior when switching sources. The TESmart HKS402-P24 promises a single, stable keyboard/mouse/audio/USB 3.0 hub across four computers and two monitors, with true 4K@60Hz support and EDID emulation to keep resolutions consistent when switching. This review tests whether it actually simplifies a complex multi-system desktop and whether the $419.99 price tag is justified.

Build and materials

The unit presents with a compact, professional-looking chassis and a sturdy front panel. Cables and connectors are robust; ports sit flush and feel secure when plugging in HDMI and USB connections. The front controls have reassuring tactile feedback, and the unit’s footprint fits easily on a desktop or in a small rack shelf.

Hands-on Experience — Pros & Cons

Pros (real-world)

• Smooth, consistent video: 4K@60Hz output was stable across Windows and macOS machines tested. EDID emulation prevents common issues like resolution drops or window reflow after switching.
• Flexible switching: Hotkeys, the mouse-wheel method, front buttons, and IR give you options depending on your workflow. Hotkeys are quick once memorized.
• USB 3.0 docking: High-speed peripheral and storage support is convenient for moving external drives or webcams to the active host without swapping cables.
• Pass-through mode: Good compatibility with many mechanical and gaming keyboards — useful for gamers who need native keyboard behaviors on each machine.
• Audio focus lock: You can lock audio to a specific port when needed, which is helpful for audio-critical workflows like streaming or conferencing.

Cons (real-world)

• Pricey for most users: At ~ $420, this is a professional-grade unit — overkill for casual single-computer setups.
• Cable management: With eight HDMI inputs and multiple USB/audio cables, setup requires planning. The box doesn’t eliminate the physical cable bulk.
• USB hub behavior: The integrated USB 3.0 hub is practical, but like most KVM hubs it exposes devices only to the currently selected host. If you need simultaneous multi-host USB access, you’ll still need a dedicated networked solution or separate USB sharing hardware.
• Initial setup nuance: EDID emulation fixes many issues but occasionally needs manual configuration for exotic monitor/refresh-rate combinations (ultrawide or high-refresh specialty displays).

Usage notes

• For mixed OS environments (Windows, macOS, Linux), hotkey mappings and USB peripheral behavior can vary — take 10–15 minutes to test and map hotkeys before critical use.
• Automatic scanning is handy for monitoring but not ideal for active workflows — use it for kiosks or passive supervision setups.

Quick Comparison — How it stacks up

Verdict from comparison: The TESmart HKS402-P24 shines where you need reliable 4K60 dual-monitor switching plus a fast USB 3.0 docking hub. Cheaper consumer KVMs may cut costs with lower USB speeds or limited EDID handling; enterprise models can match features but often at an even higher price.

Who should buy this?

• IT professionals and system administrators who manage multiple desktops/servers from a single workstation.
• Content creators and video editors who need consistent 4K performance across machines.
• Power users with mixed OS setups who want fast peripheral access and reliable video switching.
• Trading desks, control rooms, or labs where multiple host machines are required and downtime/visual glitches are costly.
• Not ideal for casual users or a single-computer home office due to complexity and price.

Quick summary: If you need professional-grade dual-monitor KVM switching with 4K@60Hz and a built-in USB 3.0 docking experience, the TESmart HKS402-P24 is a robust, reliable choice — provided you accept the higher upfront cost and plan for cable management.

Final verdict — Worth it?

Yes, for professionals: the HKS402-P24 is worth it if your workflow depends on flawless multi-computer, dual-monitor switching and you value EDID reliability and fast peripheral sharing. If your needs are more casual or single-computer, a simpler and cheaper KVM will do the job.
