The Gefen 1:4 DVI Dual Link Splitter

The 1:4 DVI Dual Link Splitter distributes a single dual link DVI source on up to four DVI dual link outputs at the same time, without losing quality or resolution. It works with any dual link DVI supporting resolutions up to 2560 x 1600. The Splitter supports EDID management, output masking, and standby mode using RS-232. In standby mode, the Splitter uses less than 1 Watt of power, even when all DVI devices are still active.

How It Works

Connect the DVI dual link source to the DVI IN port on the 1:4 DVI Dual Link Splitter, using the included 6 ft. DVI dual link cable. Connect up to four dual link DVI devices to the four DVI outputs on the Splitter. Connect the provided locking power supply to the Splitter and the AC power cord to an available electrical outlet.
