30cm DVI-D to Dual DVI-D Passive Splitter Cable
Mirror one DVI-D digital video source to two DVI-D monitors or projectors using a compact passive splitter cable.

Two mirrored displays
Sends the same image at the same resolution to two DVI-D displays; it cannot extend or span the desktop.
Passive digital splitter
Splits one DVI-D digital source to two DVI-D female outputs without external power or drivers.
30cm strain-relief lead
The integrated 30.48cm cable helps reduce leverage and strain on the source DVI port.
What to know
Both displays receive the same image and must use the same resolution. This passive splitter cannot create an extended desktop. StarTech does not recommend resolutions above 1920 × 1200 even though the technical maximum field lists 2560 × 1600, and compatibility may be limited with converted DVI outputs or docking stations.
