The Gefen 1:4 DVI Dual Link Splitter distributes a dual link DVI source to 4 DVI dual link outputs without losing quality or resolution. It works with any dual link DVI computer supporting resolutions up to 3840 x 2400. The DVI Dual Link Splitter supports internal or pass-through EDID selections, output masking On / Off, and can be placed in standby mode which keeps the unit idle using only 1W of power when the source is inactive. Its RS-232 port allows mode changes for the EDID and output masking in addition to firmware upgrades.
