RGB Spectrum QPX DIN-C – QuadPlex Mini-DisplayPort Card Version

Product Overview

The RGB Spectrum QPX DIN-C is the card version of the DisplayPort-input QuadPlex multi-display processor, with one mini-DisplayPort input and four mini-HDMI outputs. The card version exists for installations where connector depth and overall footprint matter more than cable convenience — inside furniture, a shallow enclosure, or a dense rackmount tray. Processing is that of the QuadPlex product line: RGB Spectrum publishes input support to 3840x2160 @ 60Hz, 7680x1080 @ 60Hz and 1920x4320 @ 60Hz, with four outputs at up to 1920x1200 @ 60Hz. Specify it for digital signage arrays, control room operator clusters and integrated furniture builds.

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.

What separates the QPX DIN-C from the standalone QPX DIN is connector form factor, not processing. The card version presents a mini-DisplayPort input and four mini-HDMI outputs, which shortens the connector stack and lets the unit sit in a shallower space than a full-size HDMI shell allows. That is the deciding factor in millwork, lectern and kiosk installations, and in a dense rack where ten processors are being fitted vertically rather than three horizontally.

The trade-off is adapters. A mini-DisplayPort source cable is not always to hand, and panel cabling is full-size HDMI, so the 520 12409 active mini-DisplayPort to HDMI adapter and the 520 12233-02 mini-HDMI to HDMI adapter are the two published RGB Spectrum parts that most often accompany a card-version order. Count one output adapter per panel unless native mini-HDMI cabling is being used. For rack installation, the QPX RAK rackmount tray holds up to three QuadPlex units horizontally in 1RU or ten vertically in 3RU, which is the usual way a multi-cluster signage head-end is built. Confirm source connector type, adapter quantities and layout with Creation Networks before ordering.

Key Features

• Mini-DisplayPort Input — The card version takes a mini-DisplayPort input, which distinguishes it from the mini-HDMI input on the QPX HIN-C and from the full-size DisplayPort input on the standalone QPX DIN.
• Four Mini-HDMI Outputs — Mini-HDMI output connectors reduce the connector stack depth, which is what makes the card version fit shallow enclosures and dense trays.
• Card-Version Footprint — The reduced connector depth suits millwork, lectern and kiosk installations where a full-size HDMI shell will not fit.
• 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-C
• Product type — QuadPlex multi-display card, card version
• Input — 1x mini-DisplayPort
• Outputs — 4x mini-HDMI

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-C is the card version, and the RGB Spectrum price list describes it as having one mini-DisplayPort input and four mini-HDMI outputs; the published product line table prints full-size connector types, so connector form factor differs from the table while the signal specifications are those of the product line.

Frequently Asked Questions

How does the QPX DIN-C differ from the standalone QPX DIN?
Connector form factor. The card version has a mini-DisplayPort input and four mini-HDMI outputs; the standalone QPX DIN has a full-size DisplayPort 1.2 input and four full-size HDMI outputs. RGB Spectrum publishes one specification table for the product line covering both.

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.

What adapters will I need?
For a DisplayPort or HDMI source and full-size HDMI panel cabling, the 520 12409 active mini-DisplayPort to HDMI adapter and the 520 12233-02 mini-HDMI to HDMI adapter are the published RGB Spectrum parts. Count one output adapter per panel.

Can the card version be rack mounted?
Yes. The QPX RAK rackmount tray holds up to three QuadPlex units horizontally in 1RU or ten vertically in 3RU.

Which variant should I choose for an HDMI source?
The QPX HIN-C is the card version with a mini-HDMI input. Choose the DIN-C only when the source output is DisplayPort.

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.
