4K HDMI Splitter 1x4 - Mirror 4 Displays at 4K@60Hz for TVs

Our review of the NEWCARE 4K HDMI Splitter 1 in 4 explains why this compact device is a practical choice for anyone who needs to mirror one HDMI source to multiple displays. It is best suited to classrooms, retail displays, conference rooms, and home setups where identical output is required on up to four screens. The single biggest reason to buy is its reliable 4K@60Hz mirroring with an auto downscaler that lets mixed-resolution screens share the same refresh rate without constant fiddling.

Key Features

• 4K@60Hz mirroring: Duplicates one HDMI input to four outputs so all connected TVs or monitors show the exact same UHD image and audio in sync.
• Auto downscaler: Automatically scales signals so 4K and 1080p displays operate together at a common refresh rate, reducing resolution conflicts.
• Wide codec support: Accepts common audio formats including DTS, DTS-HD, Dolby TrueHD and AC3 for preserved digital audio over each mirrored output.
• HDCP 2.2 compatible: Works with HDMI 2.0 and HDCP 2.2 protected sources like media players and game consoles when only one input is needed.
• Complete kit: Ships with a 4 ft HDMI 2.0 cable, USB power cable and adapter plus a user guide for plug-and-play setup.

Who It's For

This splitter is ideal for users who need identical content shown on multiple screens: small business owners running digital signage, presenters in meeting rooms, educators projecting the same lesson to several displays, and homeowners who want one source mirrored to multiple TVs. It works well with PCs, streaming sticks, Blu-ray players, and consoles when a single input must feed many outputs.

It is not for users who need extended desktop setups, multiple independent inputs, or external audio device routing via ARC/eARC. If you need per-screen different content, audio extraction to external speakers, or input switching between several sources, look for a multi-input matrix or an AV receiver instead.

Pros & Cons

Pros

• Reliable 4K@60Hz mirroring with synchronized audio and video across four outputs.

• Supports current high-quality audio formats and HDCP 2.2 protected sources.

Cons

• Only mirrors the same content to all screens; it does not support extended displays or multiple inputs.
• Cannot connect external audio devices or use ARC/eARC, which limits some AV setups.
