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.
