HDMI Splitter 1 in 2 out 4K, HDMI Splitter for Dual Monitors, 1 to 2 Amplifier Supports Full HD 1080P 3D, for Xbox, PS4 PS3 Fire Stick Blu Ray Apple TV Review (2026)

What this splitter is built for

This device takes one HDMI source and duplicates the exact same picture and sound to two displays at once, which is the classic use case for showing the same movie or game on both a TV in the living room and a projector screen, or on a TV and a secondary monitor. It supports HDCP 1.4 and HDMI 1.4 signaling, along with RGB 4:4:4 color and HDR pass-through at lower resolutions, and it explicitly mirrors rather than extends, so the two displays always show an identical image rather than acting like a dual-monitor desktop setup. This makes it a fit for home theater and simple dual-display needs rather than any professional video production or true independent multi-display work.

Resolution and format support

The unit supports Ultra HD 4K at up to 30Hz, along with 1080p at 60Hz and various lower resolutions, and it carries a 3D compatibility rating for older 3D Blu-ray content. This puts a ceiling on what it is good for: modern 4K streaming at 60Hz, HDR10 gaming from current consoles, or anything expecting 4K at higher frame rates is outside its spec sheet, since 4K only passes through at 30Hz here rather than 60Hz or higher. Digital audio formats including DTS-HD, Dolby TrueHD, and LPCM 7.1 are supported for pass-through, so audio quality is not typically the bottleneck when sound stays within those formats.

Compatibility notes

The listed compatibility covers Xbox, PS4, PS3, Fire Stick, Blu-ray players, and Apple TV, which lines up with the 4K30 and 1080p ceiling since most of those devices do not output beyond what the splitter supports anyway. One notable limitation called out directly is that it works with a standard PS4 but does not support PS4 Pro, likely due to the Pro's higher-bandwidth 4K output modes exceeding what the splitter's chipset can pass through cleanly. Buyers with a PS5, Xbox Series X, or other current-generation 4K60 or higher source should not expect full-quality output through this splitter, since it was designed around an older console generation's video output rather than the newest hardware.

Power and physical design

The splitter is a small unit at roughly 3 inches long by 2 inches wide by 0.6 inches tall, small enough to tuck behind a TV stand or projector cart without needing dedicated shelf space. It includes a built-in amplifier to help maintain signal strength to both outputs at once, which matters because splitting a single source's signal two ways can otherwise weaken it over longer cable runs. When the connected devices do not provide enough power through the HDMI ports themselves, an external 5V/1A power adapter is recommended to keep the amplifier running reliably rather than relying on bus power alone.

Who should buy it

This is a reasonable low-cost option for someone who wants to send an older Blu-ray player, streaming stick, or last-generation console signal to a TV and a projector simultaneously, or who needs to mirror a source to a second screen in another room using the same signal. It is not the right pick for anyone running current 4K60 or higher content, gaming at high frame rates, or expecting to extend rather than mirror a display, since none of those use cases fall within its stated specs. Buyers with newer sources like a PS5 or a 4K60 streaming box should look for a splitter explicitly rated for 4K at 60Hz and HDCP 2.2 or 2.3 instead.
