The Metra Home Theater HDMI Splitter with 1 Input and 2 Outputs has built in scaling that provides the ability to take any standard resolution and downscale it to match each of the connected displays (up to 2), simultaneously. For example, show 4K at 60 Hz content on a 4K display while also showing the same content scaled down on a 1080p display. Unlike traditional splitters, this built-in scaling allows legacy devices to work with newer higher resolution displays in the system, without automatically defaulting to the lowest resolution. Video quality on newer TVs is no longer sacrificed by having an older model in the mix!
