Special Note: This cable is one DVI-D 24+1 to two hdmi Splitter Cable, no built-in chip, when connecting two monitors, must be the same model and the same size monitor!!! Otherwise, only one display is used and the other is turned off, use it as a toggle switch, you can not turn on both monitors at the same time, and both monitors will not have an image.. DVI-D to HDMI cable can act as a signal router, for example, you may have a TV in two separate rooms, you can have a TV on in one room and when you want to switch room and keep watching the TV, you just need to switch one TV off and switch the other TV on, and then the signal is routed to the TV in the other room.. This DVI connector is DVI-D (24+1 pin). DVI-A connector is not compatible with this splitter. Cable connects only one input device (DVD player, cable box, or satellite receiver) to two same output devices (TV or projector). You cannot connect two input devices to one output device.
