ASUS HA3281A

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.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
