LG 31HN713D: 31" 12MP Mammography Monitor
Authorized LG diagnostic imaging equipment supplier. The 31HN713D is purpose-built for one application, mammography. It is one of the few mammography displays that combines a 31 inch 3:2 aspect ratio panel with a 12 megapixel native resolution and a built-in front sensor for self-calibration. It solves three persistent problems. Viewing bilateral exams requires panning on smaller displays, external calibration creates scheduling and downtime burdens, and legacy 5 megapixel mammography monitors cannot display a full tomosynthesis reconstruction stack without significant resolution loss.
The core technology is a 31 inch IPS panel at 4200 by 2800, which is 12 megapixel, with a 3:2 aspect ratio that allows bilateral CC and MLO views at near-full resolution at the same time. A front sensor self-calibration system maintains DICOM Part 14 accuracy through LG PerfectLum software without external instruments. A brightness of 1080 cd/m² with a 1500 to 1 contrast ratio supports the review of full-field digital mammography and digital breast tomosynthesis. LG positions the 12 megapixel resolution specifically as a display for mammography.

12MP 3:2 Panel, Front Sensor Calibration, and Mammography Workflow
Three things set the 31HN713D apart from a standard mammography monitor. The 31 inch 12 megapixel 3:2 panel reduces the need to pan or zoom when reviewing bilateral exams, the internal front sensor removes the external photometer dependency, and Focus View with down and wall lighting speeds reading room workflow. Full technical detail is in the expandable sections below.
Panel: 31 inch IPS, 4200 by 2800 12 megapixel, 3:2 aspect ratio
Brightness, typical: 1080 cd/m²
Contrast Ratio: 1500:1
Response Time: 5 ms in faster setting, 14 ms standard
Viewing Angle: 178° horizontal and 178° vertical
Surface Treatment: anti-glare, 3H hardness
DICOM: Part 14 compliant
Front Sensor Self-Calibration: an internal front sensor performs DICOM Part 14 calibration on a scheduled basis or on demand with no external photometer required
Hardware Calibration: supported through LG PerfectLum software for documented quality assurance records
12 Megapixel for Mammography: LG positions the 31HN713D as a 12 megapixel display for mammography, and the resolution supports review of full-field digital mammography and digital breast tomosynthesis
Multi-resolution Mode: accepts 12 megapixel at 4200 by 2800 and 6 megapixel input signals for backward compatibility with existing PACS configurations
Focus View: highlights a region of interest such as a suspicious mass or a calcification cluster while dimming the surrounding image area, without changing the PACS window and level settings
Pathology Mode: optimized color fidelity for breast pathology correlation alongside mammographic images
Down and Wall Lighting: integrated ambient illumination for reviewing reports and patient files in a darkened reading room
Reader Mode and Flicker Safe: reduce eye fatigue during long interpretation sessions
How the 31HN713D compares against a standard 5MP mammography monitor:
The 31HN713D is distinguished by its 31 inch 3:2 canvas, the largest in the LG mammography diagnostic monitor lineup, combined with a built-in front sensor for self-calibration. Breast imaging centers that replace 21 inch 5 megapixel displays can view all four standard mammographic views at near-full resolution without panning, which reduces reading time per case and supports a smoother quality assurance workflow.

Clinical Applications
Deployed in breast imaging centers, hospital radiology departments, and outpatient mammography facilities where the 31 inch 12 megapixel canvas, front sensor self-calibration, and DICOM accuracy determine reading throughput and diagnostic confidence.
Display bilateral CC and MLO views at near-full 12 megapixel resolution on the 31 inch 3:2 canvas, which removes the panning and zooming required on standard 21 inch 5 megapixel mammography monitors.
Review tomosynthesis reconstruction stacks at 12 megapixel native resolution alongside full-field acquisitions. The 1080 cd/m2 brightness and 1500 to 1 contrast support slice by slice evaluation of dense breast tissue.
2 picture by picture displays a current mammography exam and a prior study from two sources side by side at the same time for direct comparison.
Focus View and built-in down and wall lighting reduce per-case reading time in high-throughput mammography screening programs where radiologist efficiency affects patient throughput.
Pathology Mode reproduces color accuracy comparable to microscope viewing for correlating biopsy slides alongside mammographic or tomosynthesis images from the PACS workstation.
Breast imaging centers upgrading from 21 inch 5 megapixel monitors gain a single 12 megapixel canvas for all four standard views and front sensor self-calibration for simpler quality assurance.

Frequently Asked Questions
Quick answers to the most common purchase and technical questions about the LG 31HN713D mammography monitor. Tap any question to expand.
Yes. LG positions the 31HN713D as a 12 megapixel IPS display for mammography, and it is FDA 510(k) Class II cleared. Its 12 megapixel resolution and high brightness support the review of full-field digital mammography and digital breast tomosynthesis. We recommend confirming the specific FDA clearance indication and the MQSA display requirements for your facility, and our team can help you select the right monitor.
The built-in internal front sensor performs DICOM Part 14 calibration on a scheduled basis or on demand through LG PerfectLum software, with no external photometer required. This keeps the calibrated brightness consistent between cycles for reliable mammographic image quality, and hardware calibration with an external instrument is also supported for documented quality assurance records.
The 31 inch 3:2 panel lets radiologists display bilateral CC and MLO views at near-full 12 megapixel resolution at the same time, with much less panning and zooming than a smaller 5 megapixel display requires. This can reduce reading time per case and reduce eye strain during high-volume mammography reading sessions.
Focus View highlights a selected region of interest, such as a suspicious mass, a calcification cluster, or an architectural distortion, while dimming the surrounding image area. This draws attention to the area under review without changing the PACS window and level settings or losing the context of the surrounding breast tissue.
Yes. The 2 picture by picture feature displays two independent sources side by side at the same time, which suits comparing a current mammography exam against a prior study from a different PACS workstation, or viewing full-field digital mammography images alongside tomosynthesis reconstructions.
The 31HN713D supports 12 megapixel at 4200 by 2800 and 6 megapixel input signals. The 12 megapixel native resolution is used for full-resolution mammography and tomosynthesis review, and the 6 megapixel mode provides backward compatibility with existing PACS configurations without signal converters.
The 31HN713D is a 12 megapixel mammography display with FDA 510(k) Class II clearance, and its internal front sensor self-calibration supports the routine quality control documentation that MQSA and ACR programs expect. We recommend confirming the current display quality assurance requirements for your accreditation, and our team can assist with calibration setup and documentation.
