Overview
The ASUS HA3281A is a 31.5-inch (31.5-inch viewable) medical OLED monitor providing 8MP (3840 x 2160) resolution with a pure RGB stripe OLED panel, AGLR anti-reflection coating and integrated calibration tools for clinical imaging workflows.

Key features

• 31.5-inch 8MP (3840 x 2160) pure RGB OLED true 10-bit panel
• Anti-Glare, Low-Reflection (AGLR) surface with Eye Care+ for prolonged viewing
• Compliant with DICOM Part 14 GSDF; supports AAPM TG270 and TG18 protocols
• DICOM preset plus auto compensation of DICOM curve for ambient light changes
• Built-in motorized flip colorimeter for Self and Auto calibration (no external tools required)
• Factory calibrated to ensure Just-Noticeable Difference (JND) < 10%
• Multiple I/O: DisplayPort 1.4, HDMI (v2.0) x3, USB-C (DP Alt Mode) and USB3.2 Gen2 hub; earphone jack
• Ergonomic adjustments: tilt, swivel, pivot and 0–130 mm height range; bundled two-way stands
• Picture-by-Picture (PbP) and Picture-in-Picture (PiP) for multi-source comparison
• True black rendering and very high native contrast typical of OLED
• Metal carrying handle and bundled cable-management clips
• Energy-saving Eco-mode and hard-switch off for power control

OLED and image quality
Pure RGB stripe OLED with self-emissive pixels delivers extreme contrast and accurate grayscale for medical images. 10-bit color depth and high pixel density support detailed 8MP imaging and multi-window diagnostic workflows.

Calibration and color management
Integrated motorized colorimeter enables standalone self-calibration and automatic calibration with internal storage of LUTs and color profiles. Factory calibration ensures DICOM accuracy and JND < 10% for consistent grayscale gradation.

Connectivity & workflow
Comprehensive connectivity for clinical and workstation environments: USB-C (DP Alt Mode), DisplayPort 1.4, HDMI (v2.0) x3, USB3.2 Gen2 Type-A hub and earphone jack. Supports per-window color modes (sRGB, DICOM, user) and PbP/PiP for side-by-side comparisons.

Ergonomics & sensors
Includes ergonomic two-way and standard stands with tilt, swivel, pivot and 0–130 mm height adjustment. Integrated ambient light sensor (shared with colorimeter) and proximity sensor adapt brightness to environment and user presence.

Compliance & reliability
Designed for healthcare use with references to DICOM Part 14 GSDF, IEC 60601-1-2, AAPM TG270, TG18 and ISO 13485. Energy-efficient features and Eco-mode support reduced power consumption.
