This Portta N3MX41QSC multiviewer combines four HDMI sources onto one display. It suits control rooms, home theatres and multi-console gaming setups that need simultaneous monitoring. The unit includes an IR remote and RS232 control for flexible operation.

Six viewing modes include quad view, side-by-side, top-and-bottom, picture-in-picture, full screen and one-large-plus-three-small layouts. A built-in scaler handles 720p and 1080p sources, while HDCP 1.3 and 1.4 support keeps protected content working. It does not pass 4K signals or higher refresh rates.

Thermals noise and power

The compact black enclosure measures 8.39 in by 3.51 in by .7 in and weighs .581 kilograms. It ships with a USB-A to USB-C power cable and an external adapter, drawing minimal power with no fan noise. Audio extracts via Toslink for 5.1-channel surround or 3.5mm for stereo 2.0 output.

Questions about this item

Will the Portta N3MX41QSC downscale my 4K security camera feeds to 1080p for the multiview output?

Yes, the multiviewer includes a downscaler that converts higher-resolution inputs to 1080p@60Hz so all four sources appear correctly on the single output.

How can I confirm the IR remote or RS232 commands are switching the four HDMI inputs without delay?

The unit performs seamless switching in full-screen mode, so each button press or RS232 command changes the visible source instantly with no black-screen pause.

Does the box include HDMI cables for the four inputs and the single output, or must I supply them?

The package contains the multiviewer, IR remote, power adapter, USB-A to USB-C power cable and user manual; HDMI cables are not included and must be purchased separately.
