It takes a signal from one device and will direct to one of two output devices that are plugged into it. This HDMI splitter cable is great for connecting one HDMI compatible device to two visual output devises.
High Definition image resolutions such as 720p,1080i,and 1080p.
Note Only mirror/duplicate screen, NOT SUPPORT EXTEND!
ONLY 1 output device can be active at any time.
UNLESS both TVs are of the same size,then both TV will show the images when connected.you have to unplug one HDMI from this splitter to get a clear picture on the one you're using, not simply power off one of them.
