How the 21HQ613D compares against a standard office monitor:
The 21HQ613D built-in front sensor and multi-resolution modes change the economics of a diagnostic reading station. The internal sensor lets LG Calibration Studio perform hardware DICOM calibration on a schedule without an external photometer, which reduces calibration service requirements across a fleet. Multi-resolution support means one display handles 5MP mammography and breast imaging, 3MP general radiography, and 2MP cross-sectional review, so a mixed-use reading room does not need a separate display for each modality.

Clinical Applications
Deployed across diagnostic reading rooms, breast imaging review stations, and mixed-modality PACS workstations where 5MP resolution, multi-resolution flexibility, self-calibration, and daisy chain connectivity provide clinical and operational value.
Multi-resolution 5MP, 3MP, and 2MP modes let one display handle mammography and breast imaging, chest X-ray and general radiography, and CT, MRI, and ultrasound from a single PACS workstation, reducing the number of displays in a mixed-use reading room.
Per LG, the 21HQ613D displays full-field digital mammography and digital breast tomosynthesis, along with breast MRI, at 5MP with a 0.165 mm pixel pitch and 1,100 cd/m² brightness. Confirm the appropriate display class for primary interpretation with your physicist.
The built-in front sensor and LG Calibration Studio perform hardware DICOM Part 14 calibration without an external photometer, with brightness stabilized at 600 cd/m² between cycles, which reduces calibration service requirements across a fleet.
The DisplayPort daisy chain output drives a second 21HQ613D at 5MP and 48Hz from a single workstation output, which supports a two-screen reading layout in a compact footprint without a second graphics card port.
The compact 21.3-inch form factor suits remote and home reading environments where desk space is limited, while retaining 5MP resolution, DICOM Part 14 calibration, and front sensor QA at the remote workstation.
Down and Wall lighting, the Presence Sensor, Reader Mode, and Flicker Safe support long reading sessions in darkened rooms, and the five hot keys change modes and lighting without navigating the on-screen menu.
Calibration, PACS Integration, and Dual-Monitor Setup
Front sensor calibration, multi-resolution PACS compatibility, DisplayPort daisy chain, specialized viewing modes, and reading room lighting 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 21HQ613D.
Built-In Front Calibration Sensor: the integrated front-facing sensor measures panel luminance and corrects the hardware lookup table to maintain the DICOM Part 14 grayscale display function, without an external photometer. Brightness is stabilized at 600 cd/m2 between full calibration cycles.
LG Calibration Studio: the calibration software runs scheduled hardware calibration and exports calibration logs and DICOM conformance reports for departmental quality assurance documentation.
No external photometer: this reduces sensor maintenance, storage, and QA scheduling across a multi-monitor fleet.
Multi-Resolution Mode: the 21HQ613D accepts PACS workstation outputs at 5MP, 3MP, or 2MP and displays each at full panel resolution. 5MP suits mammography and breast imaging, 3MP suits chest X-ray and general radiography, and 2MP suits CT, MRI, and ultrasound. The display applies the appropriate calibration for each input, so one monitor serves a mixed-modality reading station without separate displays for each modality.
DisplayPort Out, daisy chain: using DisplayPort Multi-Stream Transport, the output passes the signal to a second 21HQ613D so two displays run at 5MP and 48Hz from a single workstation DisplayPort output. This supports a two-screen reading layout where the graphics card has one available DisplayPort output.
Inputs: two DisplayPort inputs and one DVI-D Dual Link input cover current and legacy workstation connections, and two USB 3.0 upstream and two downstream ports provide hub connectivity.
Focus View Mode: highlights a selected region of interest while dimming the surrounding area, using just the mouse and keyboard, for evaluating subtle findings without changing zoom or pan.
Pathology Mode: a color profile that provides clarity and color accuracy as if viewing through a microscope.
Light Box Mode: a uniform bright field for film and document review.
Down and Wall Lighting: downward illumination for reading documents and rear wall lighting to reduce eye strain in darkened reading rooms.
Presence Sensor: powers the display off after five minutes with no detected motion, which saves energy and helps protect on-screen patient images.
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 Reader Mode and Flicker Safe support eye comfort.
Bi-Directional Auto Pivot Stand: 110 mm height adjustment, -5 to +20 degree tilt, plus/minus 15 degree swivel, and bi-directional pivot with automatic image rotation, plus VESA 100 by 100 mm mounting.
