ARENTI 4K 2x2 HDMI Video Wall Controller 2 in 1 accessory

4K HDMI matrix and video wall controller

This ARENTI unit combines a 4x4 HDMI matrix, a 2x2 video wall controller and a 4x1 multiviewer in a single rack-mountable device. It accepts four HDMI sources such as PCs, consoles or media players and routes them to four displays simultaneously or independently. The hardware suits installers and AV integrators who need flexible signal distribution without multiple boxes. It is not suited for buyers who require HDMI 2.1 bandwidth or 4K at 60 Hz.

23 multiview layouts and rotation options

Output one can be split into 23 picture-in-picture, picture-outside-picture or quad arrangements for monitoring several sources at once. The same output also supports 90, 180 and 270 degree image rotation at 720p or 1080p for portrait or inverted mounting. Control is handled via front-panel buttons, IR remote, RS232, LAN web GUI or an Android app, and 3.5 mm audio can be embedded or de-embedded at every input and output. Users without network infrastructure or Android devices lose two of the five control paths.

4K at 30 Hz maximum with HDCP and EDID support

The matrix passes video up to 4K at 30 Hz and remains compatible with 2K at 30 Hz and 1080p at 60 Hz signals. HDCP and EDID handling ensure handshake stability across consumer and professional sources. Four mirror modes and splicing layouts from 1x1 up to 4x1 allow creative wall configurations within the 30 Hz ceiling. Installations that need 4K at 60 Hz or higher refresh rates will exceed the controller's capabilities.
