Like our DVI Super Booster the new DVI Super Booster Plus allows the extension of HD digital video over copper DVI cable well beyond its specified 15-foot distance. Without such a device sparkles or other objectionable mutations of the video signal can appear that indicate the signal has been degraded. The DVI Super Booster Plus uses a plug-in power supply which helps to extend sparkling clear video of up to 1080p or 1920x1200 resolution at a maximum distance of 200 feet. Rest assured that with this product you can kick back at the remote end and enjoy your video experience in the most precise enthralling manner that it was intended to be. With the new Plus model improved DDC signal robustness is added giving greater noise immunity to electrical signals vital for interfacing equipment at the receiver end. The result is that exceptionally long cable extensions of high-bandwidth HDTV video sources (such as Blu-Ray (tm)) will retain seamless electrical compatibility and spectacular picture.
