The EchoSplit allows you to send an HDMI signal to two displays with different resolutions while still letting each display perform at its highest supported resolution.

Most HDMI splitters allow you to send a single HDMI signal and "Mirror" it to two or more displays. However, if one of the displays in the setup supports a lower resolution than the rest, then all of the other displays will get a lower resolution because the HDMI splitter can only send an identical resolution to all displays.

For example: If you have a 4k TV and a 1080p TV connected to a regular HDMI splitter, both TV's would only get 1080p video even if your source signal is 4k.

The EchoSplit solves this problem by sending each display the highest quality signal they can receive. For example: in the scenario described above, the EchoSplit would send a 4K signal to the 4K display and a 1080p signal to the 1080p display.

Dip switch configuration 1 is the auto downscaling mode and is recommended for most situations.

Automatic Downscaling

The EchoSplit automatically detects which display supports the lower resolution and downscales the signal being sent to that display only, and sends the original 4k signal to the 4k display.

Output port 1 takes priority, so we recommend putting the 4K display on port 1 and the 1080p display on port 2.
Please enable HDCP 2.2 and any variation of "enhanced HDMI" mode on your HDMI port for the 4K display.
Changing of refresh rates is not supported.
