RGB Spectrum QPX DIN – QuadPlex DisplayPort Multi-Display Processor

Product Overview

The RGB Spectrum QPX DIN is the DisplayPort-input QuadPlex multi-display processor: one DisplayPort 1.2 input drives four HDMI outputs in 2x2, 4x1, 1x4 and artistic layouts. It is the part to specify when a single workstation or media player output has to become a four-panel display cluster without deploying 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. Use it for digital signage arrays, control room operator clusters and conference room display walls.

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 DIN is the standalone unit with a full-size DisplayPort 1.2 input and four full-size HDMI outputs. Choosing the DisplayPort input variant is usually driven by the source: a workstation graphics card or a signage player with DisplayPort outputs feeds the processor directly, and the DisplayPort 1.2 link carries the wide 7680x1080 and tall 1920x4320 canvases the product line supports. Output side, four HDMI connections at up to 1920x1200 @ 60Hz cover the native resolution of most commercial panels, and mirrored output with scaling handles confidence and overflow screens.

The published chassis is 1.25 x 5.5 x 7.13 in at 1.1 lbs with a 15 W maximum draw, which makes placement flexible: behind a display, in a lectern, or in a rack. For rack installation, the QPX RAK rackmount tray holds up to three units horizontally in 1RU or ten vertically in 3RU. For display-mounted or wall-mounted work, the 920 12325 mounting brackets with VESA mount are the published fixing kit for QPX DIN and QPX HIN units, and the QPX BRK-4H cable retention bracket secures the four HDMI output cables against accidental disconnection in a public or high-traffic installation. Where an HDMI source is the input instead of DisplayPort, the QPX HIN QuadPlex processor is the equivalent unit. Confirm the source output format, panel native resolution and intended layout with Creation Networks before ordering.

Key Features

• DisplayPort 1.2 Input — A single full-size DisplayPort 1.2 input suits a workstation graphics output or a signage player, and distinguishes the QPX DIN from the HDMI-input QPX HIN.
• Four Full-Size HDMI Outputs — The standalone unit provides four full-size HDMI output connectors, so standard HDMI cabling runs directly to the panels.
• Compact 1.1 lb Chassis — At 1.25 x 5.5 x 7.13 in the processor mounts behind a display, in a lectern or on the published rackmount tray.
• 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 DIN
• Product type — QuadPlex multi-display processor, standalone unit
• Input — 1x DisplayPort 1.2
• 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 DIN is the standalone unit with a DisplayPort 1.2 input and four full-size HDMI outputs.

Frequently Asked Questions

What is the difference between the QPX DIN and the QPX HIN?
The input connector. The QPX DIN takes a DisplayPort 1.2 input; the QPX HIN takes an HDMI 2.0 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 DIN 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, the 920 12325 mounting brackets with VESA mount are the published fixing kit.

Can the HDMI output cables be secured?
Yes. The QPX BRK-4H cable retention bracket is published for the HDMI outputs on QPX DIN and QPX HIN units, which matters in public-facing and high-traffic installations.

What are the card versions for?
The QPX DIN-C is the card version of this product, with a mini-DisplayPort 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.
