LG 21HQ513D: 3MP Radiology Display with Pathology Mode for Multi-Modality Diagnostic Reading
Authorized LG medical imaging display supplier. The LG 21HQ513D is a 3MP diagnostic monitor built for radiology reading rooms and clinical departments where a single display must handle multiple imaging modalities – from chest X-ray to CT review to digital pathology slides. Its standout feature among 3MP monitors is Pathology Mode: a dedicated picture mode that adjusts color temperature and saturation to match brightfield microscopy characteristics, enabling pathologists and radiologists to review whole-slide images on the same DICOM-calibrated display used for general radiography without reconfiguring the display between use cases.
Core specifications: 21.3-inch IPS panel at 1536×2048 (3MP) with 1,100 cd/m2 brightness that exceeds the 300 cd/m2 of standard desktop monitors – essential for detecting subtle lung nodules and soft-tissue detail in chest radiographs read in mixed-light environments. Built-in front calibration sensor maintains DICOM Part 14 compliance automatically without external photometer dependency. DisplayPort daisy chain enables dual-monitor reading room setups from a single workstation GPU output. FDA 510(k) Class II cleared for diagnostic imaging interpretation.

Pathology Mode, 3MP DICOM Display, Front Sensor Calibration & Reading Room Workflow Tools
The LG 21HQ513D addresses the needs of diagnostic radiology reading rooms through five core capabilities: high-brightness IPS for ambient-light environments, automated DICOM calibration, Pathology Mode for whole-slide image review, multi-modality resolution flexibility, and ergonomic adjustments for long reading sessions. Each capability is detailed in the expandable sections below.
Pathology Mode is a factory-preconfigured picture preset on the LG 21HQ513D that adjusts the monitor’s color rendering to match the visual characteristics of brightfield microscopy for H&E and other stained histology slides. Standard radiology monitors with DICOM GSDF calibration prioritize grayscale accuracy over color fidelity – appropriate for X-ray and CT, but not optimized for pathology where eosin pink and hematoxylin purple are diagnostically significant color distinctions.
Pathology Mode shifts the white point and increases color saturation to reproduce the warm-toned, high-contrast appearance of optical microscopy. Pathologists reviewing whole-slide images on Aperio, Hamamatsu, or Leica digital pathology platforms can switch to Pathology Mode with a single hot key press, make their color-based tissue assessments, then return to DICOM mode for radiology cases – all without recalibrating the display between use cases.
Panel type: 21.3-inch IPS (In-Plane Switching)
Native resolution: 1536 x 2048 (3MP)
Brightness (peak): 1,100 cd/m2 – more than 3x the brightness of standard desktop monitors
Viewing angle: 178 deg / 178 deg for consistent image quality across multiple radiologist positions
DICOM calibration: Part 14 hardware calibration via built-in front sensor
Brightness stabilization: Active luminance regulation maintains consistent cd/m2 output between full calibration cycles
The 3MP resolution (1536×2048) at 21.3 inches provides a pixel pitch appropriate for chest radiograph interpretation, general CR/DR reading, and detailed review of CT/MRI reformats. For facilities with CR-based general radiography systems outputting 3MP images, the 21HQ513D displays them at true native resolution without upscaling or letterboxing.
The integrated front calibration sensor performs DICOM Part 14 grayscale standard display function (GSDF) calibration automatically at scheduled intervals. This eliminates the need for an external photometer and removes the QA scheduling burden that comes with monitors requiring periodic physicist-administered calibration visits. Between full calibration cycles, the brightness stabilization system continuously monitors luminance output and adjusts the backlight to maintain target brightness.
Calibration documentation is generated via LG Calibration Studio Medical and exportable as PDF or CSV reports for inclusion in radiology department QA records. This supports accreditation documentation requirements for ACR-accredited radiology practices and hospital radiology departments subject to TJC standards.
Focus View: Highlights a user-defined region of interest at full brightness while dimming surrounding areas – useful for closely examining a specific lung zone, bone cortex, or area of pathological interest without panning or zooming.
Down Lighting: Provides directional ambient illumination from the monitor base for report writing in darkened reading rooms, removing the need for a separate desk lamp.
Wall Lighting: Back-panel ambient illumination reduces the perceived luminance contrast between the display and the room, decreasing eye fatigue during long reading sessions.
Presence Sensor: Automatically turns off the display after 5 minutes of inactivity, protecting patient image privacy when the radiologist steps away from the workstation and reducing unnecessary energy consumption.
5 Hot Keys: One-press access to Down Light, Wall Light, Presence Sensor, Light Box Mode, and Picture Mode (including Pathology Mode toggle) without navigating on-screen menus.
DisplayPort In: 2 x DisplayPort inputs
DisplayPort Out: MST daisy chain to a second 21HQ513D at 3MP resolution from a single GPU output
DVI-D: Single-link DVI for legacy workstations without DisplayPort output
USB 3.0 Upstream: 2 x USB 3.0 for hub connectivity
Auto Luminance Sensor: Ambient light sensor adjusts display brightness based on room lighting conditions, maintaining perceived contrast and reducing eye strain as overhead lights change throughout the clinical day.
The DisplayPort daisy chain is particularly useful in radiology reading rooms where the PACS workstation GPU has limited outputs but the department’s hanging protocol calls for a two-monitor layout for chest or abdominal radiology reading. Both displays show different PACS views simultaneously at 3MP from a single cable run.

Where the LG 21HQ513D 3MP Diagnostic Monitor Fits in Your Department
The 21HQ513D is purpose-built for clinical environments where one high-brightness DICOM-calibrated display must handle multiple imaging modalities and disciplines. Its Pathology Mode makes it the only 3MP diagnostic monitor in the LG portfolio that bridges radiology and pathology in a single unit.
3MP resolution matches the native output of CR and DR general radiography systems. 1,100 cd/m2 brightness with DICOM Part 14 calibration supports primary reading of chest, abdominal, and extremity X-rays in mixed-light clinical environments.
Handles CR/DR general radiography, CT multiplanar reformats, MRI, and ultrasound from a single PACS connection. Radiology groups consolidating multiple imaging modality reading onto fewer workstations benefit from the 21HQ513D’s 1,100 cd/m2 brightness at 3MP.
Pathology Mode reconfigures color rendering for whole-slide image review on Aperio, Hamamatsu, Leica, and Philips digital pathology platforms. Pathologists in departments integrating digital pathology alongside radiology PACS can use the same display for both workflows with hot key switching.
Compact 21.3-inch form factor with 3MP resolution is ideal for home or remote reading environments where desk space is limited. FDA 510(k) Class II cleared for diagnostic imaging interpretation at any remote location with PACS connectivity.
Urgent care centers and outpatient imaging facilities that read their own CR/DR X-rays benefit from an affordable, compact DICOM-compliant display that fits on a standard desk and calibrates itself automatically between QA checks.
Direct replacement for aging 3MP monitors (NEC MD211C2, Barco Coronis 3MP, Eizo RadiForce GS320). DisplayPort input is compatible with current PACS workstation GPUs. Built-in calibration eliminates the ongoing cost of external photometer hardware tied to the legacy displays.
Reading Room Integration, PACS Workstation Compatibility, and Pathology Workflow Setup
The 21HQ513D connects to any PACS workstation with DisplayPort or DVI-D output. It is compatible with all major radiology PACS platforms including Sectra IDS7, Philips IntelliSpace, GE Centricity, Merge Radiology, Fujifilm Synapse, and Agfa NX Workstation, as well as general-purpose PACS viewers used in smaller practices.
For radiology departments transitioning from older 3MP DVI-D monitors, the 21HQ513D accepts DVI-D input directly without adapters. For new workstation deployments, DisplayPort provides the primary connection with daisy chain capability for dual-monitor setups from a single GPU output.
Activating Pathology Mode on the LG 21HQ513D requires pressing the assigned Hot Key (configurable via the OSD) to cycle to the Pathology Mode picture preset. No software installation or PACS reconfiguration is required. The monitor switches from its DICOM GSDF calibrated state to the color-optimized Pathology Mode within seconds.
When switching back to radiology reading, pressing the Hot Key returns the display to DICOM mode. The brightness stabilization system re-engages immediately and the DICOM Part 14 GSDF response curve is restored – ensuring that cross-sectional images and radiographs displayed after pathology review meet the same calibration standard as before the mode switch.
Two LG 21HQ513D monitors can be connected in a daisy chain using DisplayPort MST. The first monitor connects to the PACS workstation GPU via DisplayPort; the second monitor connects to the first monitor’s DisplayPort Out. Both displays run at 3MP simultaneously from one GPU output. This is the standard deployment configuration for radiology reading rooms using hanging protocols that require two monitors for a standard left/right or current/prior image layout.
