4K 1x4 HDMI Extender Splitter Over CAT6/7 - 4 Receivers, 4K30Hz

In this review of the 4K 1x4 HDMI Extender Splitter Over CAT6/7, the bottom line is simple: it is for installers and AV users who need to send one HDMI source to multiple displays across a building without signal compression. The reviewer found the unit useful for digital signage, classrooms, and small venues because it combines a built-in HDMI loop out for a local display with four remote receivers and supports up to 4K@30Hz over CAT6/7 to 165 ft, or longer runs at 1080p. It is a practical, plug-and-play option when simplicity and distance matter.

Key Features

• 1 in 4 out splitter: Splits a single HDMI source into one local loop out plus four identical remote outputs so the same content appears on five screens simultaneously.
• Long-distance 4K transmission: Supports up to 50 m (165 ft) at 4K@30Hz over CAT6/7 cable, letting displays sit far from the source while keeping 4K resolution.
• Extended 1080p reach: Supports approximately 60 m (196 ft) at 1080p@60Hz for longer runs when Full HD is sufficient.
• EDID presets: The TX unit includes EDID preset options to improve compatibility between sources and displays and help ensure correct video and audio formats.
• No compression transmission: Passes HDMI signals without compression and supports audio formats such as PCM, DTS, and DSD for preserved AV quality.
• Wide device compatibility: Plug-and-play design works with PCs, set-top boxes, game consoles like PS4/PS5, DVD players, and common Android boxes for quick setup.

Who It's For

This product is ideal for IT integrators, small business owners, educators, and AV hobbyists who need to distribute one HDMI source to multiple displays across a campus, shop, or worship space without complex configuration. It fits installations where a local monitor is needed at the source plus several remote screens connected over CAT6/7 cable.

It is less appropriate for users who require 4K@60Hz, HDR pass-through, or wall-to-wall consumer plug-and-play simplicity with wireless distribution. Also, environments that lack quality CAT6/7 cabling or require very long runs beyond the stated distances should consider alternatives.

Pros & Cons

Pros

• Delivers one source to four receivers plus a local loop out for flexible display placement.
• Makes 4K content available up to 165 ft over CAT6/7 with no compression, preserving image and audio quality.
• EDID presets help match source and display expectations and reduce handshake issues.
• Broad compatibility with common AV sources and simple plug-and-play setup.

Cons

• Limited to 4K@30Hz, so users wanting 4K@60Hz or HDR performance will need a different solution.
• Performance depends on quality of CAT6/7 cabling and installation; poor cabling can reduce range or reliability.
