Accell Corporation
UltraAV® 1x4 HDMI Splitter

By Kevin Nakano

Accell 1x4 HDMI SplitterAccell Corporation has recently introduced the new UltraAV® Mini 1x4 HDMI® Audio/Video Splitter (MSRP $149.99, Street $100) designed to deliver HDMI video to four displays including all HD resolutions (1080p and 3D) from a single source. The unit is perfect for situations where multiple users want access to the same source, such as a Bluray player or set-top box, with multiple HDMI TVs, projectors and monitors. The unit is compatible with all HDCP compliant devices and is capable of data rates as high as 6.75 Gbps (225 MHz). This splitter can also handle streaming Dolby® TrueHD and DTS-HD lossless data along with 36-Bit Deep Color. This compact chassis measures approximately 6" x 3" x 1" (WxLxH) and weighs a modest 9 ounces.

Front Indicators
The front of the Accell Mini 1x4 HDMI® Audio/Video Splitter only has indicators for power and display output status. There are no controls to deal with. The leftmost indicator (power) will remain on while the other four indicators only illuminate if the corresponding output is connected to a display. These lights are bright, so if you plan to use this in a theater room you will probably want to hide it or cover the display.

Accell 1x4 HDMI SplitterRear Interfaces
There are a total of five HDMI connectors on the back of the splitter along with a power input jack and power switch. One HDMI input and four HDMI outputs are available. Not all outputs need to be connected for this to work. A universal (100-240VAC) AC adapter provides power (5VDC @3A) to the unit. We connected an OPPO BDP-95 Bluray player to the source input and ran the outputs to various monitors, including a Mitsubishi HC7800U 3D projector.

Immortals 3DPerformance
The Accell 1x4 HDMI Splitter design includes an integrated 4-Port DVI/HDMI splitter chip along with a microcontroller for seamless operation. The unit delivered as advertised with excellent video performance to all our 1080p monitors including a 3D Mitsubishi HC7800U projector. When running 3D source material, it should be noted that any non-3D display will cause the 3D content to default to 2D. The integrated HDCP decryption/encryption engines provide a secure handshake with compatible displays to fully support protected content.

In addition to our shorter cable runs, we also tested the splitter using a long Accell 25-meter UltraRun 1.3 HDMI cable connected to our Mitsubishi HC7800U 3D projector. The drive capability of the Accell 1x4 HDMI Splitter was excellent with pristine video performance regardless of whether it was 2D or 3D content. Our test disc Immortals 3D provided good test images with some dark scenes that revealed good shadow detail. The 3D content looked excellent with no degradation in video quality.

The Accell 1x4 HDMI Splitter provides an economical way to distribute high quality HDMI video from a single source to four high resolution displays without any video degradation. The highly integrated splitter is both compact and low power. If you have been looking for a way to get your content to more than one display, Accell's new 1x4 HDMI Splitter will meet your needs.
