DVS400 extends any DVI-D Signal up to 220 feet to four displays and one local screen using CAT6 cabling while retaining perfect image quality at resolutions up to 1920 x 1200. SmartAVI, Inc.’s DVS400 allows you to extend a DVI-D signal to up to four displays via one small unit that also loops a signal back to your computer so local monitoring is possible and simple. A great example would be a retail shop running its digital signage from a computer in its back office using the DVS400, a media file or group of files could be broadcast to up to four screens situated around the store while also being viewed locally on that computer’s monitor. On power-up, the DVS400 reads and stores the EDID of the DVI monitor connected to the local loop-back port. From that point on, even if the local monitor is not attached to the unit, its DDC is retained in the flash memory of the DVS400 unit and it will operate as if the monitor were connected, offering unhindered use and simple flexibility.
