4x1 HDMI Switch 4K HDMI Switcher Box - Easy 4-Device Sharing

In this review the TESmart 4x1 HDMI Switch emerges as a practical solution for anyone who needs to share a single display among multiple HDMI sources. Its biggest selling point is straightforward: reliable 4K 60Hz switching with optical and analog audio extraction, which makes it useful for a living room or small conference setup where clarity and audio routing matter. The unit is not a KVM and does not pass USB signals, but for video and audio switching it delivers predictable performance with simple plug-and-play setup.

Key Features

• 4x1 HDMI switching: Lets four HDMI devices share one monitor or projector so a single screen can be used for console gaming, streaming, and a set-top source without constant cable swapping.
• 4K@60Hz and HDR support: Handles 3840x2160 at 60Hz with 4:4:4 chroma and HDR so high-resolution video and color fidelity are preserved on compatible displays.
• Optical and analog audio out: Includes S/PDIF and L/R outputs so you can route audio to a soundbar or audio system independently of the HDMI output device.
• Automatic and manual switching: Offers automatic input detection plus front-panel button and IR remote control for quick manual selection when needed.
• Wide compatibility: Works with common HDMI sources such as gaming consoles, Blu-ray players, streaming boxes, and projectors for flexible use across home and office setups.

Who It's For

The TESmart 4x1 is best for homeowners and small office users who need a simple, reliable way to share a single display among multiple HDMI devices and want higher-resolution support and audio extraction. Gamers with a console mix, home theater builders who need S/PDIF output, and presenters moving between laptops and media players will find it convenient.

It is not for users who require USB switching, keyboard and mouse sharing, or advanced KVM features; those buyers should look for a product specifically labeled as a KVM switch. Also, if you need networked control or multi-monitor output, a matrix switch would be a better fit.
