Review (April 2006)
By Kevin Nakano
Long cable runs have introduced challenges for many front projector installations, especially for those needing HDCP compliant signals from their sources. Some projector owners have opted for the more costly cable extenders, which often require expensive electronics and/or fiber optic cables. Accell Corporation has taken a different approach with the introduction of their new HDCP compliant UltraRun HDMI cables. These new cables cleverly integrate a small signal equalizer and booster right into the connector housing resulting in outstanding performance even with long cable runs. The low-power design allows the electronics to operate directly from most HDMI sources, so that no additional power is needed in most applications. However, Accell does provide a small AC adapter (5V, 500mA) with the cable that mates to the display side of the cable in the event additional power is needed. We are not sure what active electronics is in the cable, but we suspect Accell may be adding pre-emphasis to the differential drive signals to improve the "eye" (signal integrity) at the receiving end. High purity copper conductors and nitrogen-injected dielectrics help maintain excellent signal integrity over the length of the cable. The high bandwidth design supports resolutions of up to 1080p and has a UL (Underwriters Laboratories) listed CL3 rating, making it perfect for many of today's in-wall installations. The cables also use triple metal shielding to protect against EM and RF interference. The HDMI connectors feature 24K gold-plated connectors and contacts for reliable and low contact resistance. The UltraFlex jacket provides a sturdy, yet flexible cable design that is easy to route.
We tested a variety of D-Theater tapes including Cast Away, U-571 and True Lies. These movies use D-Theater technology and often have dropouts if poor cabling is used to carry the data. We have encountered this in the past and are quite sensitive to digital cable issues. We were very pleased that this long 40 meter cable did not exhibit any dropouts during our tests. We continued watching content from our HD-Net archives on D-VHS and some over-the-air broadcasts such as the Tonight Show. Video quality was consistently excellent each and every time we viewed high resolution content.
