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

The ASUS HA3281A is a 31.5 inch 4K OLED monitor designed for healthcare environments that demand precise and reliable medical imaging. With an 8 megapixel native resolution of 3840 × 2160, the screen delivers the detail required for reviewing diagnostic images, surgical videos, and clinical photographs.

The panel uses a true 10-bit RGB stripe structure, allowing accurate grayscale gradations that meet DICOM Part 14 GSDF. Factory tuning keeps every just-noticeable difference below 10 percent, so subtle changes in tissue, bone, or vascular structures remain visible when a radiologist or technician scrolls through studies.

A colorimeter that is motorized sits inside the bezel and handles both self-calibration and scheduled automatic calibration. Because the process runs without external software, image consistency is preserved even when the display is moved between reading rooms, operating theaters, and consultation areas.

The screen surface has an anti-glare and low-reflection coating, and ASUS Eye Care Plus manages blue light and flicker. An ambient light sensor also adjusts the DICOM curve on the fly, maintaining accurate luminance as room lighting changes in day-night clinical operations.

Connection options include USB-C with DisplayPort Alt Mode and power delivery, a pair of HDMI inputs, a DisplayPort input, and a USB hub for peripherals such as dictation microphones or calibration tools. The stand supports tilt, swivel, pivot, and height movements, so users can position the monitor for seated reporting, standing consultations, or portrait viewing of full-length X-ray series.

Compliance with IEC 60601-1-2, AAPM TG18 and TG270, and ISO 13485 confirms that the HA3281A integrates smoothly into regulated medical workflows. Radiology reading rooms, cardiology labs, pathology departments, and point-of-care ultrasound stations can all benefit from the combination of 4K clarity, DICOM accuracy, and automated upkeep.
