40Gbps performance, native experience, lag-free gaming: Five key improvements
1. Full retention of Pro Display XDR Professional Capabilities – No compromises
While the THK401-X4 combines signals from multiple sources, its PC1 Thunderbolt™ channel maintains all core functions of the XDR fully available: 1600 nits peak brightness, P3 color gamut, 10-bit color depth, and reference mode are all perfectly passed through. You don't have to choose between "multi-device switching" and "professional display quality."Every color and brightness detail, carefully calibrated by Apple, is reproduced as accurately as with a direct connection.
2. Optimized for gaming consoles – Pure hardware passthrough without delay
Especially for PS5/PS4, Xbox Series X|S and Nintendo Switch Developed with this technology in mind, the THK401-X4 eschews the compromises of traditional capture cards that rely on PC-based software encoding and frame buffering, opting instead for pure HDMI hardware passthrough – driverless, without background processes, and plug-and-play. Once the gaming console is connected, video signals undergo no system-wide rendering or protocol conversion. Commands and refresh rates are perfectly synchronized. Whether it's precise combos in God of War or perfect dodges in Elden Ring, input lag is reduced to an imperceptible level. 4K@60Hz-Ausgabe und With the native color performance of the XDR, you can enjoy an immersive gaming experience on a Retina-level screen that rivals dedicated gaming monitors.
3. HDMI audio passthrough – Direct sound via external audio system
The THK401-X4 supports full HDMI audio passthrough. Audio signals from PS5/PS4, Xbox, or Nintendo Switch are routed directly to the Pro Display XDR workflow in sync with the video (external speakers or audio system required, as the XDR has no built-in speakers). Adjust game volume in real time using keyboard shortcuts – say goodbye to the "picture without sound" problem of traditional adapter solutions and enjoy immersive sound that perfectly complements reference-quality picture.
4. Tested in real desktop environments – Verified Thunderbolt™ display compatibility
Equipped with the Intel JHL8440 chip for Thunderbolt™ protocol processing, the product extensively tested in real-world environments. It supports popular Thunderbolt™ displays such as the Pro Display XDR, LG UltraFine 5K, and Dell U2725QE. Native protocol passthrough technology ensures full interaction of video, audio, and data channels – seamless integration into Thunderbolt™ ecosystem workflows.
5. Not just for Macs – work PCs can also be easily connected.
The THK401-X4 forgets Windows users No. A dedicated HDMI + USB-B input channel allows your work PC to be easily integrated into this display hub and benefit from full KVM control – a single keyboard and mouse are all you need for seamless switching between Mac and PC. Whether you're developing across platforms, testing dual systems, or working on everyday office tasks and creating content, no additional peripherals are required, and there's no need to constantly unplug and replug cables. One screen, two ecosystems, seamless switching.
Core functions – Fully equipped
1. Integrated Gigabit Network Sharing – Central management of the wired network
Connecting only a single Ethernet cable to the KVM allows multiple hosts to share a stable Gigabit wired network.The integrated independent network switch supports on-demand isolation or multiplexing of network channels – say goodbye to Wi-Fi fluctuations and cable clutter.
2. PC1 Thunderbolt™ channel with 60W PD power supply
PC1's Thunderbolt™ port integrates the 60W Power Delivery fast-charging protocol. MacBook users can simultaneously perform video output, high-speed data transfer, and device charging via a single cable. No additional power adapter is required—keep your desk minimalist and focus on efficient work or mobile working.
3. HDMI EDID retention – No layout reset when switching
Traditional KVM switching often triggers display re-handshakes, leading to resolution renegotiations, window misalignments, and application layout glitches. The THK401-X4 features an integrated EDID emulation chip that continuously simulates display presence for HDMI devices. When switching sources, HDMI devices maintain stable detection—desktop layout, multi-screen coordinates, and color profiles remain precisely locked for truly seamless transitions.
4. USB 3.2 High-Speed Peripheral Matrix – One set of controllers for all
An integrated USB data sharing channel allows keyboards, mice, webcams, and external drives to automatically follow the active video source. No more repeated plugging and unplugging or manual reconnection – one switch migrates your entire peripheral setup, significantly reducing desktop clutter and driver conflicts in multi-device workflows.
5. Four-way switching control – adapted to any workflow
Choose between front panel physical buttons, customizable keyboard hotkeys, mouse wheel quick-switching, or infrared remote control. Whether you're coding at your desk, multitasking between windows, or working remotely, route signal sources instantly based on intuition—the transition between work and entertainment has never been smoother.
