RGB Spectrum QPX HIN – QuadPlex HDMI Multi-Display Processor

Product Overview

The RGB Spectrum QPX HIN is the HDMI-input QuadPlex multi-display processor: one HDMI 2.0 input drives four HDMI outputs in 2x2, 4x1, 1x4 and artistic layouts. Specify it where the source is an HDMI device — a media player, laptop, codec or camera — and a four-panel display cluster is required without a full video wall processor. RGB Spectrum publishes input support up to 3840x2160 @ 60Hz, 7680x1080 @ 60Hz and 1920x4320 @ 60Hz for the QuadPlex product line, with four HDMI outputs at up to 1920x1200 @ 60Hz. It suits digital signage arrays, conference room display walls and control room operator clusters.

Product Description

RGB Spectrum publishes the QuadPlex as a single product line under the name "QuadPlex Multi-Display Processor" and prints one specification table for it. That table lists the video input as "1x HDMI (2.0) or 1x DisplayPort (1.2)" in a single row and does not separate the four ordering variants. The variants differ by input connector: the QPX DIN takes a DisplayPort 1.2 input, the QPX HIN takes an HDMI 2.0 input, and the QPX DIN-C and QPX HIN-C are the card versions of the same two products, with mini-DisplayPort and mini-HDMI inputs respectively and four mini-HDMI outputs in place of the standalone units' full-size HDMI outputs.

The QPX HIN is the standalone unit with a full-size HDMI 2.0 input and four full-size HDMI outputs. HDMI on both sides is the practical choice in most commercial rooms, where sources and panels are already standardised on HDMI cabling and no adapters are wanted in the signal path. The published product line supports 3840x2160 @ 60Hz along with the wide 7680x1080 and tall 1920x4320 canvases, and each of the four HDMI outputs carries up to 1920x1200 @ 60Hz with HDCP 1.4 or HDCP 2.2, so protected sources reach the displays.

Mechanically the unit is 1.25 x 5.5 x 7.13 in at 1.1 lbs with a 15 W maximum draw. For rack installation, the QPX RAK rackmount tray takes up to three units horizontally in 1RU or ten vertically in 3RU, which is how a signage head-end serving several display clusters is usually built. Behind a display or on a wall, the 920 12325 mounting brackets with VESA mount are the published fixing kit for QPX DIN and QPX HIN. Cable retention is available on both sides of the QPX HIN: the QPX BRK-4H bracket secures the four HDMI outputs, and the QPX BRK-1H bracket secures the HDMI input, which is specific to this variant because only the QPX HIN has an HDMI input to retain. Where the source is DisplayPort instead, the QPX DIN QuadPlex processor is the equivalent unit. Confirm source format, panel native resolution and layout with Creation Networks before ordering.

Key Features

• HDMI 2.0 Input — A single full-size HDMI 2.0 input matches the standard commercial source connector and distinguishes the QPX HIN from the DisplayPort-input QPX DIN.
• Four Full-Size HDMI Outputs — Four full-size HDMI output connectors let standard HDMI cabling run directly to the panels with no adapters in the path.
• Retention on Input and Outputs — Cable retention brackets are published for both the four HDMI outputs and the HDMI input on this variant, which suits public-facing installations.
• Published Input Resolutions — The QuadPlex product line accepts 3840x2160 @ 60Hz, 7680x1080 @ 60Hz and 1920x4320 @ 60Hz, with 30Hz variants of each, so wide and tall canvases are handled natively.
• Four Independent Outputs — Four HDMI outputs each carry up to 1920x1200 @ 60Hz, which matches the native resolution of most commercial display panels.
• Layout Flexibility — Published single-unit configurations include 2x2, 4x1, 3x1, 2x1, 1x2, 1x3, 1x4 and artistic layouts in portrait and landscape orientation.
• Mirrored Output with Scaling — The product line supports mirrored output with scaling, which suits confidence displays and overflow screens showing the same content.
• Multi-Unit Support — Multi-unit operation is published for the product line, so display counts beyond four are built by adding processors.
• HDCP on Input and Output — HDCP is published on the input, with HDCP 1.4 or HDCP 2.2 on the outputs, so protected sources can be carried to the display wall.
• Ethernet Management — A 1x Ethernet 10/100/1000 Base-T port supports network configuration and management from the head-end.
• Low Power Draw — Maximum published power consumption is 15 Watts on a 100 x 240VAC / 50-60 Hz supply, so a processor behind a display adds little heat load.

Typical Applications

• Digital Signage — One source drives a four-panel array in a lobby, retail space or transport concourse without a full video wall processor.
• Control Room — A single workstation output is split across four operator panels at a supervisory position.
• Command Center — Portrait and landscape layouts let a compact display cluster match the room's sightlines.
• Operations Center — A 15 W processor per display cluster keeps power and heat load low in a continuously staffed room.
• Boardroom — A wide 7680x1080 canvas from one source spans a four-panel presentation surface.
• Conference Room — Mirrored output with scaling feeds a main display and a confidence screen from the same input.
• Training Room — Instructor content is distributed to four screens so every seat has a clear view.
• Auditorium — Overflow and side displays are driven from the same source as the main screen.

Technical Specifications

• Part number — QPX HIN
• Product type — QuadPlex multi-display processor, standalone unit
• Input — 1x HDMI 2.0
• Outputs — 4x HDMI
• HDCP — HDCP compliant

RGB Spectrum publishes one specification table for the QuadPlex product line rather than per part number: the strings QPX DIN, QPX HIN, QPX DIN-C and QPX HIN-C do not appear in the vendor datasheet, and the published table prints the video input as a single row, "1x HDMI (2.0) or 1x DisplayPort (1.2)". The values below are therefore the QuadPlex product line specifications as published by RGB Spectrum. The QPX HIN is the standalone unit with an HDMI 2.0 input and four full-size HDMI outputs.

Frequently Asked Questions

What is the difference between the QPX HIN and the QPX DIN?
The input connector. The QPX HIN takes an HDMI 2.0 input; the QPX DIN takes a DisplayPort 1.2 input. Outputs, layouts and published specifications are those of the same QuadPlex product line.

What resolutions does the QuadPlex product line support?
RGB Spectrum publishes input resolutions of 3840x2160 @ 60Hz, 7680x1080 @ 60Hz and 1920x4320 @ 60Hz with 30Hz variants, and output resolutions of 1920x1080 @ 60Hz and 1920x1200 @ 60Hz with 30Hz variants.

Are the specifications published per part number?
No. RGB Spectrum publishes one specification table for the QuadPlex product line and does not print the QPX DIN, QPX HIN, QPX DIN-C or QPX HIN-C designations. The values on this page are the product line specifications.

Can several units be combined for more than four displays?
Yes. Multi-unit support is published for the product line. Confirm the intended display count and layout with Creation Networks so the processor quantity is correct.

How does the QPX HIN mount in a rack?
The QPX RAK rackmount tray holds up to three units horizontally in 1RU or ten vertically in 3RU. For display or wall mounting, use the 920 12325 mounting brackets with VESA mount.

Can both the input and output cables be retained?
Yes, and this is specific to the HDMI-input variant. The QPX BRK-4H bracket secures the four HDMI outputs and the QPX BRK-1H bracket secures the HDMI input.

Is there a card version of this product?
Yes. The QPX HIN-C is the card version, with a mini-HDMI input and four mini-HDMI outputs instead of full-size connectors.

What warranty and support apply?
The RGB Spectrum manufacturer warranty applies to this part number. Creation Networks supports specification, configuration review and procurement, and can route warranty and technical support requests to RGB Spectrum.
