J-Tech Digital JTECH-SP12M18G 1x2 HDMI video splitter 4K@60Hz downscaling

1x2 HDMI splitter with downscaling

This 1x2 HDMI splitter sends one source signal to two displays simultaneously, mirroring the image on both screens. It supports up to 4K@60Hz resolution with HDMI 2.0 and HDCP 2.2 compliance. The unit includes a built-in downscaling function that converts a 4K input to 1080P for one output while passing 4K to the other. Three EDID modes (auto, copy, downscale) help resolve handshake issues between mixed displays.

Replaces basic splitters without downscaling

A standard splitter forces both displays to run at the lowest common resolution, limiting a 4K screen to 1080P if the second display is older. This unit solves that by downscaling 4K to 1080P independently per output, so each display receives its native resolution. The upgrade is worth it when you run a 4K TV and a 1080P projector or monitor from the same source. It does not downscale to 720P or strip HDR metadata.

Simple setup with included brackets

Connect the source to the single HDMI input and the two displays to the outputs, then attach the supplied power adapter. The splitter is powered externally, so it does not draw power from the HDMI ports. Mounting brackets are included for a secure installation on a wall or rack. Common issues arise if cables exceed the recommended length for 4K@60Hz or if the source device ignores the selected EDID setting, requiring a manual mode change.
