ASUS HA3281A 32" 16:9 60Hz 4K OLED HealthCare Monitor

Overview

The ASUS HA3281A is a 31.5-inch 4K OLED healthcare monitor designed to deliver precise and reliable medical imaging with an 8 megapixel native resolution of 3840 × 2160. It provides the clarity needed for reviewing diagnostic images, surgical videos, and clinical photographs, ensuring subtle details in tissue, bone, or vascular structures remain visible. The monitor’s true 10-bit RGB stripe panel supports accurate grayscale gradations compliant with DICOM Part 14 GSDF, making it well suited for demanding clinical environments.

Key features

• Motorized colorimeter enables self-calibration and scheduled automatic calibration without external software, maintaining consistent image quality across different clinical settings.
• Factory calibration ensures just-noticeable differences remain below 10 percent, preserving subtle image details critical for medical analysis.
• Anti-glare and low-reflection coating combined with ASUS Eye Care Plus technology reduces blue light and flicker, enhancing viewing comfort during long reading sessions.
• Ambient light sensor dynamically adjusts the DICOM curve to maintain accurate luminance as room lighting changes throughout day and night operations.
• Versatile connectivity options include USB-C with DisplayPort Alt Mode and power delivery, two HDMI inputs, DisplayPort input, and an integrated USB hub for peripherals like dictation microphones or calibration tools.
• Ergonomic stand supports tilt, swivel, pivot, and height adjustments, allowing users to position the monitor comfortably for seated or standing use and portrait viewing of full-length X-rays.
• Compliance with IEC 60601-1-2, AAPM TG18 and TG270, and ISO 13485 standards ensures seamless integration into regulated medical workflows.
