The new DVI DL Booster Plus allows the extension of massive desktop resolutions over dual-link digital video cable well beyond its default limit of a 15-foot distance. Without such a device, sparkles or other objectionable mutations of the video signal can appear. Such degradations are completely unacceptable, especially where computer applications are concerned, where desktop images must be sharp, clear and bright for productive work to take place. The DVI DL Booster Plus uses a plug-in power supply which helps to extend sparkling clear video images to great distances (up to 200 feet at 2560x1600). Rest assured that with this product, you can enjoy your computer desktop as if the computer was in the same room as the display. With the new Plus model, improved DDC signal robustness is added, giving robustness to electrical signals that negotiate delicate resolution and frequency settings, for even greater precision than ever before. To go beyond the limited inherent DVI distance or if you'd like to use two or more cables, our Boosters are a perfect option. They replicate digital video signals, enabling you to inchdaisy chaininch cables and Boosters as far as you need to go.
