3-Port HDMI switch connects three HDMI source devices to one port on an HDMI monitor while allowing you to switch back and forth between each one. Three separate ports allow you to connect your Blu-ray player, video game system and cable/satellite DVR to one HDMI port on your high-definition television. Or you can connect three computers or media centers to a monitor for displaying digital signage or presentations. IR extender receiver lets you hide the switch out of sight while still being able to switch devices using the remote. Energy-efficient design automatically switches to the next powered-on device when it's powered off. Hassle-free functionality requires no software, drivers or external power supply for immediate use. Switch supports Ultra High Definition (UHD) video resolutions up to 3840 x 2160 (4K x 2K) at 24/30 Hz and 48-bit True Color, as well as DTS-HD, Dolby True-HD and 7.1-channel surround sound audio.
