SEETEC monitor D71-H （Dual 7"""" 3RU）2*7 inch

SEETEC D71-H Dual 7" 3RU Rack Monitor – Dual 7" IPS 1080x800 with Ethernet Software Control

The SEETEC D71-H is a dual 7" 3RU rack monitor designed for broadcast and live-event monitoring. It pairs two 7” IPS 1080x800 screens in a thin, lightweight 3RU rack chassis. You can view SD and HD video, use built-in tally lights, and control the units over Ethernet with included software.

Thin, lightweight 3RU design for rack installations

The D71-H fits standard 3RU rack spaces and keeps a compact footprint. Because it is extremely thin and lightweight, you can install multiple units in broadcast trucks, control rooms, or mobile production rigs without adding unnecessary bulk.

High-quality IPS displays for consistent images

Each screen uses an IPS panel to deliver wide 178°/178° viewing angles. The displays output up to 400 nit brightness, so you can see accurate and consistent images from different viewing positions across the control room or vehicle.

Simple, unified operation

The D71-H follows a consistent design and operation style found in its product family. This means once you learn the control scheme on one unit, you can operate related models with the same workflow. As a result, setup and daily operation become faster and more convenient.

Multiple inputs and outputs for flexible signal routing

Each LCD on the D71-H supports common broadcast inputs and outputs, making it easy to connect cameras, switchers, or playback devices. The available ports on each screen include:

• Input: HDMI × 1
• Input: CVBS × 1
• Input: Audio (L/R) × 2
• Output: HDMI × 1
• Output: CVBS × 1
• Audio: Stereo headphone output

Network control over Ethernet

The D71-H includes a LAN port and supports software control via Ethernet. The rear-panel LAN 100 port connects the unit to your local network. The included software lets operators locate the IP address of any connected unit via the MAIN MENU → NETWORK CONFIGURATION submenu, then enter that IP into the software’s address bar.

Once connected, you can control multiple D71-H monitors from a single software instance. Select which monitor(s) to manage, send commands to those units, and monitor real-time status through the software’s NETWORK tab. This approach helps maintain consistent signals and simplifies large installations.

3-color front tally lights

Each screen has front-facing tally lights with three colors (Red, Green, Yellow). The tally lights accept DB-9 input signals on the rear panel, allowing integration with existing tally systems in studio or outside-broadcast setups.

Industrial-grade stability and reliability

Rack-mount monitors often run continuously, so the D71-H is built to industrial quality standards. The full metal case improves durability and contributes to effective heat dissipation, helping the monitor operate reliably in broadcast and mobile environments.

Built-in monitoring tools and features

The D71-H provides a range of practical monitoring aids to support focus, framing and color checks. Key on-screen tools include:

• Peaking Focus Assist
• Pixel to Pixel
• Centre Marker
• Screen Marker (80%, 85%, 90%, 93%, 96%, 2.35:1)

Smart FAQ

question: How do I control multiple D71-H monitors from one computer?
Answer: Connect each D71-H to your LAN using the rear-panel LAN 100 ports. Open the MAIN MENU on a unit and go to NETWORK CONFIGURATION to find its IP address. Enter that IP into the provided software. From the software’s NETWORK tab you can poll the LAN for other connected units, select which monitors to control, and send commands to those selected monitors.

question: What video sources can I connect to each screen?
Answer: Each LCD supports HDMI and CVBS inputs, plus two audio L/R inputs. For most setups you can route camera feeds, switcher outputs or playback devices via HDMI or composite (CVBS) and monitor audio through the stereo headphone output.

question: Can the tally lights integrate with my existing tally system?
Answer: Yes. Each screen has front LED tally indicators in red, green and yellow. They accept DB-9 input signals on the rear panel, so you can connect and control them from typical studio tally systems.

question: Is the D71-H suitable for continuous operation in broadcast trucks or mobile rigs?
Answer: Yes. The D71-H is built to industrial quality standards and uses a full metal case. This construction improves durability and helps with heat dissipation, making it suitable for continuous operation in broadcast environments and special vehicles.

question: Which on-screen tools are available to help with focus and framing?
Answer: The monitor includes practical tools such as peaking focus assist, pixel-to-pixel, centre marker, multiple screen markers (including 2.35:1), image flip, check field (RGB, mono), image freeze, zoom functions and U/D & L/R zoom to assist focus, framing and color checks.
