How the 21HQ513D compares against a standard office monitor:
The 21HQ513D is built so a single display can serve a mixed-modality reading station. Its DICOM Part 14 calibration and 1,100 cd/m² brightness support primary radiology reading, while Pathology Mode renders whole-slide images with microscope-like color when the reader switches to digital pathology. The built-in front sensor and PerfectLum run hardware calibration on a schedule without an external photometer, and multi-resolution 3MP and 2MP modes let one monitor handle general radiography and cross-sectional review, which reduces the number of displays a mixed-use reading room needs.

Clinical Applications
Purpose-built for clinical environments where one high-brightness DICOM-calibrated display handles multiple imaging modalities and disciplines, with a Pathology Mode that bridges radiology and digital pathology in a single unit.
3MP resolution matches the native output of CR and DR general radiography systems, and 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.
Multi-resolution 3MP and 2MP modes let one display handle general radiography, CT multiplanar reformats, MRI, and ultrasound from a single PACS connection, which suits groups consolidating modality reading onto fewer workstations.
Pathology Mode renders whole-slide images with microscope-like color for review of slides from common digital pathology platforms, so a department integrating digital pathology alongside radiology can use one display for both with a hot key switch.
The compact 21.3-inch form factor suits home and remote reading where desk space is limited, while retaining 3MP resolution, DICOM Part 14 calibration, and front sensor QA. FDA 510(k) Class II cleared for diagnostic imaging interpretation.
Urgent care centers and outpatient imaging facilities reading their own CR and DR X-rays gain a compact DICOM-compliant display that fits a standard desk and calibrates itself between QA checks with the built-in front sensor.
A direct replacement for aging 3MP reading monitors, with DisplayPort input compatible with current PACS workstation graphics outputs and built-in calibration that removes the ongoing cost of external photometer hardware.
Calibration, PACS Integration, and Pathology Workflow
Front sensor calibration with PerfectLum, Pathology Mode, multi-resolution PACS compatibility, DisplayPort daisy chain, and reading room comfort features combine to support diagnostic reading rooms and mixed-modality workstations. Expand each section for detail required by radiologists, IT administrators, and biomed teams evaluating the 21HQ513D.
Built-In Front Calibration Sensor: the front sensor measures panel output and corrects the hardware lookup table to maintain the DICOM Part 14 grayscale display function, without an external photometer. A backlight sensor stabilizes luminance between calibration cycles.
PerfectLum: the bundled medical display calibration and QA software runs scheduled hardware calibration and exports calibration and conformance reports for departmental quality assurance documentation, which supports ACR-accredited practice and hospital department QA records.
No external photometer: this reduces sensor maintenance and QA scheduling across a multi-monitor fleet.
Pathology Mode: a dedicated picture mode that renders stained digital pathology slides with accurate color similar to viewing directly under a microscope. Standard DICOM grayscale calibration prioritizes grayscale for X-ray and CT, while Pathology Mode reproduces the warm-toned color that pathologists rely on for tissue assessment.
Hot key switching: the reader presses a hot key to enter Pathology Mode for whole-slide image review and returns to the DICOM calibrated state for radiology cases, with no software installation or PACS reconfiguration required.
Multi-Resolution Mode: the 21HQ513D displays 3MP and 2MP inputs at optimized quality. 3MP suits chest radiography and general radiography, and 2MP suits CT, MRI, and ultrasound, so one display serves a mixed-modality reading station without a separate monitor for each modality.
Inputs: two DisplayPort inputs and one DVI-D input cover current and legacy workstation connections, and two USB upstream and two downstream ports provide hub connectivity.
DisplayPort Out, daisy chain: using DisplayPort Multi-Stream Transport, the output passes the signal to a second 21HQ513D so two displays run at 3MP and 60Hz from a single workstation DisplayPort output. This is the standard configuration for reading rooms whose hanging protocol distributes current and prior studies across two monitors, without a second graphics output.
Narrow side bezel: minimizes the gap between two pivoted displays for a near-seamless dual-monitor reading surface.
Presence Sensor: turns the display off when no motion is detected, which saves energy and helps protect on-screen images when the reader steps away.
Auto Luminance Sensor: adjusts brightness automatically to ambient room light.
Dual Controller: a software KVM that lets one keyboard and mouse control two connected computers, and Text Mode and Flicker Safe support eye comfort.
Ergonomic One-Click Stand: a lightweight body with tool-less setup, tilt -5 to +20 degrees, 90 degree pivot, and 110 mm height adjustment, plus VESA 100 by 100 mm mounting.

Frequently Asked Questions
Common questions from radiologists, pathologists, IT managers, and procurement teams evaluating the LG 21HQ513D for diagnostic reading rooms, multi-modality PACS workstations, and digital pathology review.
Pathology Mode is a dedicated picture mode that adjusts color rendering so that stained digital pathology slides appear with accurate color similar to viewing directly under a microscope. Standard DICOM grayscale calibration prioritizes grayscale accuracy for X-ray and CT, while Pathology Mode reproduces the warm-toned color that pathologists rely on for tissue assessment. It is reached with a single hot key press, and the display returns to its DICOM calibrated state for radiology cases.
Yes. The 21HQ513D is FDA 510(k) Class II cleared for diagnostic imaging interpretation. With 1,100 cd/m2 brightness, DICOM Part 14 hardware calibration maintained by the built-in front sensor, and 3MP (1536 by 2048) resolution, it supports primary reading of chest radiographs, musculoskeletal X-rays, and review of CT, MRI, and ultrasound in a multi-modality reading room.
The 21HQ513D is a 3MP (1536 by 2048) display for general radiology and digital pathology, with Pathology Mode and multi-resolution 3MP and 2MP support. The 21HQ613D is the 5MP (2048 by 2560) version that adds resolution for higher-detail review and, per LG, displays full-field digital mammography, digital breast tomosynthesis, and breast MRI. Both are LG diagnostic displays that share the same front sensor calibration and DisplayPort daisy chain. Confirm the appropriate display class for your specific reading task with your medical physicist.
Yes. The DisplayPort Out supports Multi-Stream Transport daisy chaining to a second 21HQ513D at 3MP and 60Hz. Both displays run simultaneously from a single DisplayPort GPU output, which suits reading rooms that need a two-monitor hanging protocol layout without an additional graphics output.
No external photometer is required. The 21HQ513D has a built-in front calibration sensor and a backlight sensor, and it runs hardware DICOM Part 14 calibration through PerfectLum medical calibration software. The front sensor measures panel output to maintain the grayscale display function, the backlight sensor stabilizes luminance between cycles, and PerfectLum generates calibration and QA reports for departmental documentation.
Multi-resolution mode lets the 21HQ513D display 3MP and 2MP input signals at optimized quality. This suits mixed-modality reading where the workstation sends 3MP general radiography or 2MP CT, MRI, and ultrasound, so one display serves several modalities.
Pathology Mode is a display color preset, so it is independent of the slide platform and works with whole-slide images from common digital pathology systems such as Aperio, Hamamatsu, and Leica viewed on a PACS or pathology workstation. The reader toggles Pathology Mode with a hot key for slide review and returns to DICOM mode for radiology.
