The SIIG 1×4 HDMI 1.3 Distribution Amplifier provides a simple way to split a single HDMI connection and outputs it to 4 different HDMI sources. I’ve used HDMI splitters in the past and none of them worked as I expected, so I actually gave up on them until now. I just got a copy of the SIIG 1×4 HDMI splitter and after days of testing, it has performed better than I expected.

The SIIG 1×4 HDMI 1.3 Distribution Amplifier looks great. It’s one of the better designed HDMI splitter I’ve seen. It’s simple yet great to look at. I’m loving the design.

The lights next to the HDMI slots will turn on when the HDMI are plugged in. It’s nothing special, but it looks cool. It also includes a USB slot to easily update your firmware.

The other side of the device has no inputs.

The SIIG 1×4 HDMI 1.3 Distribution Amplifier includes a screw kit if you prefer it to be mounted.

The SIIG 1×4 HDMI 1.3 Splitter

The SIIG 1×4 HDMI Splitter is a simple way to effectively broadcast HDMI signals from one source to four different displays. It will split high definition video and high quality audio to four different sources without losing quality. This HDMI splitter will deliver resolution up to 1080p or WUXGA (1920×1200 @ 60Hz) and supports Deep Color, xvYCC color space, DTS-HD Master Audio, Dolby TrueHD, Dolby Digital, DTS, DVD-Audio, LPCM, SACD and MPC

Setup & Testing

The SIIG 1×4 HDMI is easy to setup and only takes a few minutes to hook up all of your sources. It’s as simple as plugging in the HDMI signal you want to split in the HDMI IN slot and your display sources to the HDMI OUT slots to get started. After that, power on the HDMI splitter and your display sources. That’s it.

For testing purposes, I wanted to split my cable box signal to four different display sources. It took me awhile to move my display sources to one place, but after moving all my display sources and hooking them up to the SIIG 1×4 HDMI splitter, the video and quality audio were excellent. The SIIG 1×4 HDMI splitter does a great job at splitting the signal as I saw no lost in video or audio quality.


The SIIG 1×4 HDMI 1.3 Distribution Amplifier is the perfect HDMI 1.3 splitter. The signal is perfect when the video and audio are split. I don’t notice any quality lost when the signal is split into four different display sources.

This is a HDMI 1.3 splitter so there is no 3D or 4Kx2K support. SIIG does sell a 1×4 HDMI Distribution Amplifier with 3D and 4Kx2K Support though, but it will cost you more. SIIG also sells 1×2, 1×4, 1×8, 1×10, 1×16, and 2×4 HDMI splitters so check them out if you are looking for a different size splitter.

If you are looking for a HDMI 1.3 splitter then the SIIG 1×4 HDMI 1.3 Distribution Amplifier is a must have as it does it’s job perfectly. I’m not a fan of 3D TVs even though I have one and 4K resolutions TV aren’t popular yet, so the SIIG 1×4 HDMI 1.3 Distribution Amplifier is perfect for me.
