4K HDMI Multiviewer Switch 4x4 - Quad 4 in 4 Out Multiviewer

Our review of this 4K HDMI multiviewer switch 4x4 finds it best suited for small control rooms, multiroom AV setups, and gamers who need to manage multiple sources simultaneously. The single biggest reason to buy is its flexible multiview output on Output A, which offers six viewing modes so one display can show multiple inputs at once while the other three outputs mirror or show independent sources. It is not a simple splitter; it is a compact matrix and multiviewer that balances image quality with practical audio extraction for 5.1 or 2.0 setups.

Key Features

• 6 Viewing Modes: Choose from 4 equal screen, dual side-by-side, dual up and down, PIP, full screen, and 1 big with 3 small to tailor a single display layout to your workflow.
• 4x4 Matrix Routing: Connect up to four input sources to four HDMI outputs with independent routing, letting outputs B, C, and D show any single input or replicate Output A.
• Audio Extraction: Output A includes SPDIF 5.1CH and 3.5mm 2.0CH audio outputs so you can send multichannel or stereo audio to separate speakers or an AVR.
• Seamless Switching: In Output A full screen mode the unit switches between inputs without the usual 5-8 second delay seen on many consumer switches, improving live monitoring and source changes.
• 4K@30Hz Support: The device supports up to 4K at 30Hz and is backward compatible with 1080p/720p while offering scaler options between 1080p, 1600p, and 4K@30Hz for Output A.
• Wide Compatibility: Works with a variety of HDMI sources such as game consoles, PCs, Blu-ray players, streaming sticks, and security camera feeds for flexible home or small-business use.

Who It's For

This multiviewer is ideal for small production booths, security monitoring stations, conference rooms, or homes where one wants to view multiple HDMI sources on a single 4K display while still sending independent signals to other screens. Users who need quick, seamless full-screen switching on one primary monitor and multiview arrangements will benefit most.

It is not the best choice for those who require 4K at 60Hz, professional broadcast-grade switching with frame-accurate genlock, or extremely ruggedized industrial hardware. Casual users who only need a simple HDMI splitter without multiview or audio extraction should look at simpler alternatives.

Pros & Cons

Pros

• Flexible multiview layouts let a single display show up to four sources in useful configurations.
• Independent routing lets outputs B, C, and D mirror the multiview or show any single source.
• Built-in SPDIF and 3.5mm audio extraction supports both 5.1 and 2.0 audio workflows.
• Generally reliable picture quality and easy setup reported by users, making it good value for multiroom use.

Cons

• Limited to 4K@30Hz, so it will not deliver 4K at 60Hz needed by some gamers or high-frame-rate applications.
• Some users report occasional signal loss or durability concerns in heavy daily use, so expect standard consumer-level reliability.

Specifications

Our Verdict

The 4K HDMI Multiviewer Switch 4x4 is a practical, cost-effective multiview and matrix solution for anyone who needs to manage several HDMI sources without breaking the bank. It delivers solid picture quality, convenient audio extraction, and useful layout modes, making it a smart choice for monitoring, light production, and multiroom setups - provided you do not require 4K at 60Hz or industrial durability.

Frequently Asked Questions

Does it support 4K at 60Hz?
No. The unit supports up to 4K at 30Hz; for 60Hz you will need a different model.

Can outputs B, C, and D show the same multiview as Output A?
Yes, outputs B, C, and D can either replicate Output A or independently display any one of the four inputs.

Is there built-in audio extraction?
Yes. Output A provides SPDIF 5.1CH and a 3.5mm 2.0CH audio output for external audio devices.
