LG 21HQ613D: 5MP Mammography Monitor for FFDM and Digital Breast Tomosynthesis
Authorized LG medical imaging display supplier. The LG 21HQ613D is a purpose-built 5MP mammography reading display designed for radiologists who need an FDA-cleared breast imaging monitor in a compact 21.3-inch form factor. It solves three real problems faced by breast imaging centers: the need for a compact yet high-brightness FFDM display for space-limited reading rooms, the burden of external calibration sensor scheduling, and the lack of a monitor that handles both mammography and general radiology from a single unit. With FDA 510(k) Class II clearance specifically for full-field digital mammography and digital breast tomosynthesis interpretation, the 21HQ613D delivers clinical confidence at a footprint smaller than most 8MP diagnostic monitors.
Core specifications: 21.3-inch IPS panel at 2048×2560 (5MP) with a 0.165mm pixel pitch that resolves microcalcifications sharply enough for primary FFDM reading. 1,100 cd/m2 peak brightness with brightness stabilization at 600 cd/m2 via the built-in front calibration sensor – maintaining DICOM Part 14 compliance between scheduled calibration cycles without the need for an external photometer. Multi-resolution mode (5/3/2MP) allows the same workstation to send mammography, chest X-ray, and CT data to a single display, reducing reading room hardware costs.

Built-in Front Sensor, 5MP FFDM Resolution & Mammography Reading Room Tools
Four technologies make the LG 21HQ613D the most practical 5MP mammography reading display for high-volume breast imaging centers. High-brightness IPS eliminates washout in brightly lit reading environments. The built-in front calibration sensor removes the need for external photometers and reduces MQSA QA scheduling burden. Multi-resolution mode handles every modality from a single display output. And Focus View with Down/Wall Lighting accelerates case review without adding supplementary equipment.
Panel type: 21.3-inch IPS (In-Plane Switching)
Native resolution: 2048 x 2560 (5MP)
Pixel pitch: 0.165 mm – resolves microcalcifications at primary FFDM reading distances
Brightness (peak): 1,100 cd/m2
Brightness (DICOM stabilized): 600 cd/m2 via brightness stabilization
Contrast ratio: 1,800:1
Viewing angle: 178 deg / 178 deg (H/V)
Response time: 8 ms
Surface treatment: Anti-glare hard coating
The 5MP resolution at 21.3 inches provides sufficient pixel density for primary mammography reading of FFDM images and review of digital breast tomosynthesis reconstruction stacks. The IPS panel’s 178-degree viewing angle ensures color and brightness consistency regardless of radiologist seating position.
The integrated front calibration sensor measures actual panel luminance and automatically adjusts the backlight to maintain the DICOM Part 14 grayscale response curve. Calibration runs without interrupting clinical workflow – scheduled calibration cycles execute when the display is idle, and the brightness stabilization system compensates for luminance drift continuously between full calibration cycles.
No external photometer required – eliminates the cost of sensor maintenance, storage, and QA scheduling. Calibration logs and DICOM compliance documentation are accessible via LG Calibration Studio Medical software, supporting MQSA audit trail requirements. Brightness is stabilized at 600 cd/m2 – above the minimum 450 cd/m2 required for primary mammography interpretation under FDA guidelines.
Multi-resolution mode allows the 21HQ613D to accept PACS workstation outputs at any of three resolutions and display them at full panel resolution without distortion. This is essential for facilities where radiologists read multiple modalities on the same workstation:
- 5MP mode: Full-field digital mammography (FFDM) and digital breast tomosynthesis (DBT)
- 3MP mode: Chest X-ray, CR/DR general radiography, fluoroscopy review
- 2MP mode: CT, MRI, ultrasound, nuclear medicine review
Switching between modes requires no hardware changes – the display automatically detects the input resolution and applies the appropriate grayscale calibration for each modality.
Focus View: Highlights a selected region of interest at full 1,100 cd/m2 brightness while dimming the surrounding display area – useful for evaluating subtle mass margins or architectural distortions without changing zoom or panning.
Down Lighting: Provides downward ambient illumination from the base of the monitor for writing reports in a darkened reading room without requiring a separate desk lamp.
Wall Lighting: Projects ambient light from the back of the display to reduce eye strain during extended reading sessions by increasing room luminance behind the screen.
5 Hot Keys: Instant one-button access to Down Light, Wall Light, Presence Sensor, Light Box Mode, and Picture Mode – eliminating on-screen menu navigation during reading.
Presence Sensor: Automatically powers off the display after 5 minutes of no detected motion in front of the screen, protecting patient image privacy and saving energy.
DisplayPort In: 2 x DisplayPort inputs for flexible workstation connection
DisplayPort Out: Daisy chain output enables a second 21HQ613D at 5MP / 48Hz from a single graphics card output – ideal for dual-monitor FFDM reading setups that require two 5MP displays but the workstation GPU has limited outputs.
DVI-D Dual Link: Legacy connectivity for existing mammography acquisition workstations
USB 3.0 Upstream: 2 x USB 3.0 upstream ports for hub connectivity
Auto Luminance Sensor: Adjusts panel brightness automatically based on ambient room light levels, maintaining calibration accuracy as reading room lighting changes throughout the day.
The 21HQ613D ships with an ergonomic stand providing the full range of adjustments required for mammography reading rooms. Height adjusts 110mm to fit seated or standing radiologists. Tilt from -5 to +20 degrees accommodates desk angle preferences. Swivel of plus or minus 15 degrees enables sharing between workstation positions. Pivot of plus or minus 90 degrees allows rotating to landscape orientation for non-mammography modalities – with auto rotation detection that automatically flips the on-screen image when the panel is pivoted, requiring no software configuration.
VESA mount: 100 x 100mm for alternative mounting solutions including articulating arms and wall-mount brackets used in compact mammography reading rooms.

Where the LG 21HQ613D 5MP Mammography Reading Display Fits Your Facility
The 21HQ613D is optimally positioned for breast imaging centers, radiology groups, and hospital mammography programs that need an FDA-cleared 5MP mammography display at a compact 21-inch footprint. Its multi-resolution capability also makes it practical for multi-modality reading stations outside dedicated mammography reading rooms.
FDA 510(k) Class II clearance for full-field digital mammography interpretation. 1,100 cd/m2 brightness meets MQSA luminance minimums. Built-in front sensor calibration supports MQSA QA documentation without external photometer scheduling.
FDA cleared for DBT interpretation. 5MP (2048×2560) resolution with 0.165mm pixel pitch provides the spatial resolution needed for full DBT reconstruction stack review without lossy downsampling from the acquisition system.
DisplayPort daisy chain supports a second 5MP monitor from a single GPU output. Two 21HQ613D displays in a dual-monitor configuration allow bilateral CC and MLO views side by side – at a smaller desk footprint than a single 31-inch panel.
Multi-resolution 5/3/2MP support allows the same display to handle mammography, chest X-ray, and CT/MRI review from a single PACS workstation. Reduces the number of displays required in mixed-use reading rooms.
Compact 21.3-inch form factor is ideal for remote mammography reading environments where desk space is limited. FDA-cleared for primary FFDM and DBT interpretation at any remote workstation configured with a PACS connection.
Replaces legacy 5MP mammography displays (Barco Coronis, Eizo RadiForce MX) with current-generation DICOM hardware calibration, front sensor, and modern connectivity including DisplayPort – without requiring workstation GPU upgrades.
PACS Integration, MQSA QA Workflow, and Dual-Monitor Mammography Setup
Deploying a 5MP mammography monitor involves three critical workflow considerations: PACS output compatibility, MQSA calibration QA documentation, and physical reading room configuration. The LG 21HQ613D is designed to minimize friction in each area.
The 21HQ613D connects to any PACS workstation with DisplayPort output. For workstations with legacy DVI-D Dual Link outputs (common on older mammography acquisition systems), the monitor accepts direct connection without an adapter. Multi-resolution mode ensures compatibility regardless of whether the PACS sends 5MP FFDM data, 3MP general radiology data, or 2MP cross-sectional images.
Verified compatible workstation types: Hologic SecurView, GE MammoView, Fujifilm Synapse Mammography PACS, iCAD PowerLook, and general-purpose PACS review stations including Philips IntelliSpace, Sectra IDS7, and Merge Radiology.
For facilities using LG Calibration Studio Medical software, the front sensor integrates directly with the QA module to generate calibration reports compliant with MQSA documentation requirements.
Mammography display QA under MQSA requires documented luminance verification at regular intervals. The 21HQ613D’s built-in front sensor automates this process: calibration runs on a scheduled basis, maintains brightness at 600 cd/m2 DICOM-stabilized, and logs each calibration cycle for audit trail documentation. This eliminates the need to schedule external physicist visits for display calibration verification between ACR accreditation cycles.
QA record output: LG Calibration Studio Medical exports calibration logs in formats compatible with facility QA management systems. Logs include timestamp, pre/post calibration luminance readings, DICOM grayscale conformance report, and sensor verification data.
Two LG 21HQ613D monitors can be connected using a single DisplayPort output from the PACS workstation GPU via DisplayPort daisy chain (MST – Multi-Stream Transport). The first monitor connects directly to the GPU; the second connects from the first monitor’s DisplayPort Out. Both displays run at 5MP / 48Hz simultaneously from one GPU port, reducing the need for workstation GPU upgrades when adding a second 5MP display.
Standard bilateral mammography layout: Right CC / Right MLO on the left monitor, Left CC / Left MLO on the right monitor – the standard two-screen FFDM reading configuration used in most breast imaging programs. The two 21HQ613D monitors side by side occupy approximately 800mm of desk width, fitting comfortably on a standard reading room workstation desk.

LG 21HQ613D – 5MP Mammography Monitor Common Questions
Yes. The LG 21HQ613D holds FDA 510(k) Class II clearance specifically for interpretation of full-field digital mammography (FFDM) images and digital breast tomosynthesis (DBT) reconstruction stacks. This clearance confirms the display meets the luminance, spatial resolution, and calibration standards required by FDA and MQSA for primary mammography reading – it is not a general-purpose monitor with a claim of suitability, but a specifically cleared medical device for breast imaging.
Both are FDA-cleared for FFDM and DBT mammography interpretation. The 31HN713D is a 31-inch 12MP display in a 3:2 aspect ratio, designed primarily for facilities that want to display full bilateral CC and MLO views simultaneously on a single monitor at near-full resolution. The 21HQ613D is a 21.3-inch 5MP display in a 4:5 portrait aspect ratio, optimized for facilities reading one breast at a time, limited desk space environments, or installations requiring two monitors for bilateral reading in a smaller combined footprint. Both carry the same mammography-specific FDA clearance and use the same DICOM Part 14 front sensor calibration technology.
Yes. The FDA 510(k) clearance specifically includes digital breast tomosynthesis (DBT). The 5MP (2048×2560) resolution with 0.165mm pixel pitch provides sufficient spatial resolution to display DBT reconstruction slices at full native resolution from all major DBT acquisition systems (Hologic 3Dimensions, GE SenoBright, Fujifilm AMULET Innovality) without downsampling. The 1,100 cd/m2 brightness ensures visibility of subtle DBT findings that may be lost at the lower luminance levels of standard diagnostic monitors not cleared for mammography.
Using DisplayPort Multi-Stream Transport (MST), the 21HQ613D’s DisplayPort Out port connects to a second 21HQ613D’s DisplayPort In. The PACS workstation sends a single DisplayPort signal that the first monitor splits into two 5MP streams at 48Hz each. Both monitors display simultaneously at full 5MP resolution from one GPU output. This is particularly useful for workstations where the GPU has only one available DisplayPort output but the mammography reading protocol requires two 5MP displays for bilateral view layout.
