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.
