Our take on the WyreStorm Express™ HDMI Splitter

People call us every day looking for ways to display the same high-res video source on more than one screen. HDMI splitters aren't new, but the extra bandwidth demands of 4K Ultra HD video are well beyond the capabilities of typical HD-rated HDMI splitters. Good thing we have the WyreStorm Express™ SP-01024K.

High-resolution solution for dual-display video

4K HDMI Splitter (1 in/2 out): The WyreStorm Express EXP-SP-0102-4K is a professional-grade HDMI splitter with a single HDMI input and dual HDMI outputs. The WyreStorm Express splitter provides distribution and replication of a single Ultra-HD (4K) or HD (1080p) source to two separate displays. Its perfect for Retail AV, Commercial, and Hospitality installation.

Note: The EXP-SP-0102-4K does not upscale or down-convert the video signal. Make sure your TV is compatible with the video signal input and output by the EXP-SP-0102-4K.

HDMI 1.4a: Featuring HDMI 1.4a specification supporting data rates up to 10.2Gb/s, for lossless audio/video formats, full 3D and Lip Sync, the EXP-SP-0102-4K also includes 24-bit True Color with chroma-subsampling rate of 4:2:2 for 4K color palette and 36-bit Deep Color for 1080p transmissions. 

HDCP & EDID Management: Automatic HDCP and EDID management continuously negotiates and authenticates communication between connected devices, ensuring simultaneous distribution of source content to all outputs, while also maintaining signal integrity via internal equalization and amplification to output devices.

Note: The EXP-SP-0102-4K's HDMI jacks do not support the latest HDCP 2.2 copyright protection for 4K ultra-HD content, so it will not support 4K content from satellite/cable providers, online video services, and Blu-ray disc which are copyright protected with HDCP 2.2.

Transmission Distance: The EXP-SP-0102-4K provides 4K transmission over 33' or 1080p transmission over 49'.

Expandability: Systems can be further expanded by cascading multiple EXP-SP-0102-4K units to create larger distributions; with 4K transmissions cascaded twice and 1080p signals up to 12 times to the same model units for flexible, scalable solutions for residential and commercial applications. 

Compact Design: Compact for unobtrusive installations, measuring only 5.5625" (w) x 1.75" (h) x 4.0625" (d).

Customer Q&A

Crutchfield asked  
Why did you buy this?

needed this most of all [ Dave  Nov 10, 2018 ]
At your recommendation [ Richard  Jul 24, 2018 ]
Apple support said I needed an HDMI splitter to connect my TV, my AppleTV, my stereo receiver to my blue tooth receiver for my hearing aids in order to get all channels of sound when using AppleTV. As currently set up, I was unable to get sound from my center speaker when going through AppleTV for Netflix. [ Sherran  May 30, 2018 ]
Wanted to connect the bar TV to the cable receiver along with the main TV. One HDMI input to the Splitter and two HDMI outputs to the two TVs. Same picture but two different viewing areas. [ D  Jan 12, 2018 ]

2 questions already asked

The splitter does not provide the balanced line adapters (HDMI to Cat5/6) but will provide the dual HDMI outputs from a single HDMI source input. [ Ryan  Jun 09, 2018 ]  Staff
I forwarded your question to an Advisor and they responded with the following: If you are using an HDMI output from the cable box you can use the WyreStorm Express SP-0102 HDMI splitter. This will let you split to two TVs but you have to watch the same channel on both. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
