• Premium 4K distribution with 18 Gbps bandwidth and 4:4:4 color space – This 1×4 HDMI splitter sends a single 4K signal to four displays with full 4:4:4 color sampling, ensuring pristine color fidelity, sharp edges on text and graphics, and accurate skin tones. The 18 Gbps bandwidth supports 4Kx2K at 60 Hz, enabling you to reproduce detailed images and smooth motion without chroma subsampling or color degradation. Whether you’re broadcasting a marketing video, live event feed, or synchronized presentation across multiple screens, you’ll enjoy pixel-perfect output that remains faithful to the source. The splitter is plug-and-play and compatible with common 4K sources including Blu-ray players, gaming consoles, media players, and computer desktops, making it a versatile choice for multi-display setups. In environments where crisp text and precise color are critical, the UltraSlim splitter shines by minimizing color bleed and preserving fine details, so logos, charts, and captions stay legible at a glance across all outputs.

• UltraSlim, user‑friendly design for flexible mounting – The compact chassis is engineered to maximize space in tight AV cabinets or behind wall-mounted displays. Its slim profile and lightweight construction allow for easy placement on a shelf, inside a cabinet, or mounted with compatible brackets. The rugged, metal housing provides durability and helps with heat dissipation, while the small footprint reduces cable clutter and improves airflow in dense setups. With a simple, tool-free installation, you can position the splitter exactly where you need it, improving cable routing and maintenance. This is especially valuable in environments with limited rack space or when retrofitting existing systems that require a discreet, unobtrusive distribution solution without sacrificing performance.

• HDR readiness, HDCP 2.2 compatibility, and reliable signal integrity – The KanexPro UltraSlim 1×4 splitter is designed to handle modern home and professional content pipelines. It supports HDR10 and maintains HDCP 2.2 compliance, ensuring protected 4K content from sources like Blu-ray players and streaming devices can be distributed to all connected displays without handshake issues. The built-in color fidelity and robust signal integrity help prevent black levels from blooming, color shifting, or dropped frames when switching inputs or cascading cables. The combination of HDR compatibility and HDCP 2.2 makes this splitter well-suited for living rooms, classrooms, and commercial installations where high-quality visuals must be preserved across multiple screens while maintaining secure content protection.

• Powerful, reliable performance with simple, noise-free operation – This distribution amplifier is engineered for dependable operation in everyday use and demanding environments. It uses a dedicated external power supply to stabilize the signal across all outputs, minimizing the risk of handshake failures or degraded performance when multiple displays are connected. The UltraSlim design emphasizes low heat output and quiet, fanless operation, so it won’t add distracting noise to a home theater or meeting space. The device is designed for plug-and-play ease, with minimal configuration required—simply connect your source and four displays, power the unit, and let it distribute a single high‑quality signal cleanly and consistently.

• Versatile compatibility for home, business, and education use – Whether you’re mirroring a presentation across four screens in a conference room, feeding a wall of displays in a retail setting, or extending a gaming or media PC to multiple monitors, this splitter delivers reliable performance with broad compatibility. It supports a wide range of HDMI sources, including computers, Blu-ray players, gaming consoles, and streaming devices, and works with multiple HDMI cables to reach each display. The UltraSlim form factor makes it easy to integrate into existing AV installations without major rewiring, while the consistent output across all ports helps maintain a professional, synchronized look for multi-screen experiences.

How to install KanexPro UltraSlim 4K HDMI 1X4 Splitter

• Step 1 — Power off all devices: Before making any connections, turn off your source device, displays, and any associated power switches to prevent short circuits or handshake issues during setup.

• Step 2 — Connect the HDMI source: Use a high‑speed HDMI cable to connect your video/audio source (a Blu-ray player, game console, PC, or streaming device) to the splitter’s HDMI input.

• Step 3 — Connect the displays: Run four separate HDMI cables from the splitter’s outputs to the HDMI inputs on each display. Ensure each display is set to the correct HDMI input source.

• Step 4 — Apply power: Plug the included external 5V DC adapter into the splitter and connect it to a powered outlet. Powering the splitter reduces the chance of signal degradation and handshake problems when distributing to four displays.

• Step 5 — Power on and configure: Turn on the source and each display. If a display does not show a signal at the correct resolution, verify that the source supports 4K60 with 4:4:4, check HDMI cable quality, and ensure EDID is being passed through correctly. In most setups, content will display at the highest supported resolution across all outputs automatically.

Frequently asked questions

• What is a 4:4:4 color space and why does it matter? A 4:4:4 color space preserves full color information for each pixel, including fine text and graphics. This results in crisper text, sharper logos, and more accurate gradients than 4:2:0 or 4:2:2 subsampling, making it ideal for presentations, signage, and professional content where precision matters.
• Can I use this splitter with 1080p content? Yes. The device supports 4K at 60 Hz and will downscale to a compatible 1080p display as needed. All four outputs will mirror the source signal, ensuring consistent quality across displays.
• Do I need external power for reliable operation? Yes. An external power supply is required to ensure stable distribution to all four outputs and to prevent handshake or color fidelity issues on multiple displays.
• Will this splitter work with HDR content? Yes, it is HDR10 compatible and HDCP 2.2 compliant, which helps preserve HDR metadata and protected content across all outputs when used with compatible displays and sources.
• Is there any latency added by this splitter? As a passive distribution device, the splitter maintains the original signal path with negligible additional latency, which is generally imperceptible in normal playback, gaming, or presentation scenarios.
• What kinds of devices can I connect? You can connect a wide range of HDMI sources such as Blu-ray players, gaming consoles, streaming devices, and computers, then distribute the signal to up to four displays simultaneously.
