Note: Sewell HDMI Splitters are all HDCP compliant which means that this splitter does not strip or bypass HDCP. This splitter supports all versions of HDCP including HDCP 2.2.

The Sewell 1x8 SplitDeck (4K 1x8 HDMI Splitter) supports Full HD, 3D, HDR signals up to 4K@60Hz, and allows you to split a single HDMI source to two HDMI HD Displays

1x8 Distribution Amplifier

SplitDeck is an active 8-port splitter (aka distribution amplifier) which means that it actively amplifies and equalizes the input signal in order to perform at maximum spec.

HDMI 2.0

The main spec to look for when trying to find a true-HDMI 2.0 splitter is the bandwidth spec-- it should be 18 Gbps. If an HDMI splitter claims to pass this bandwidth in each channel, it can achieve full 4K 60Hz 4:4:4 chroma.

4K HDMI Cable

4K 30Hz vs 4K 60Hz

As our TVs get bigger and bigger, so does the perceived difference between refresh rates. This splitter supports 4K 60Hz while some of our other splitters outside of the SplitDeck series support 4K 30Hz, but why should you care?

As you know, video is simply a bunch of images played rapidly to give the illusion of movement. More images viewed per second equates to more-realistic video. Refresh Rates (measured in Hz) are what is used to describe the number of unique images played per second. 30 Hz means that you're seeing 30 unique images per second while 60Hz doubles the amount of images per second.

But Wait -- I thought the human eye couldn't detect individual frames much past 24 frames per second. -- That is technically true; the human eye is thoroughly convinced that they are seeing a moving image even at 24 Hz. Higher Hz rating actually makes fast-moving objects look more realistic and less blurry/jumpy.

Battling Motion Blur -- One of the outcomes of having a low Hz rating is that fast-moving objects start to look blurry. This is actually a feature of your display-- it is trying to compensate for the jarring nature of jumpy image animation. A football travelling 30 yards/second would technically only show one frame per yard when seen at 30Hz, making that throw seem unrealistic to our eyes. The TV must therefore employ motion blur or ruin the viewing experience.

Motion blur is a lot less distracting than the actual jumpiness of an image, but neither motion blur nor jumpiness are desired when watching action flicks, playing a video game, or watching sports. For those types of video content, we highly recommend that you do not settle for 30Hz.

HDCP 2.2 Splitter Compliance

Like any active HDMI component, you're going to want to start thinking about future HDCP versions. Unfortunately the new HDCP 2.2 standard is not backwards compatible. That means that if you're wanting to use an HDMI Splitter into the future that is not HDCP 2.2 compliant, it will not work with future HDTV releases or HDMI source releases.

With the SplitDeck by Sewell, since it supports HDCP 2.2, you can be sure that it will continue to work after you get that new TV someday. A lot of TVs being sold these days have at least one port that supports HDCP 2.2 and is meant for full HDMI 2.0 signals

Plug and Play

SplitDeck Connection Diagram

If you have a 1080p TV and a 720p TV, the signal sent to both from the splitter will end up being 720p unless you use a downscaler between the splitter and the 720p TV. That way, each TV will display the highest possible resolution.
