ASUS HA3281A 31.5" 4K OLED

The ASUS HA3281A is a 31.5-inch 4K Ultra HD monitor accessory designed for healthcare environments requiring DICOM Part 14 GSDF compliance. Its 8MP pure RGB stripe OLED panel delivers 10-bit colour depth and a 1,000,000:1 contrast ratio for precise greyscale and colour accuracy. Factory calibration and a built-in colorimeter support self and auto calibration to maintain long-term visual consistency for diagnostic review.

Connectivity limits of HDMI 2.0 and DP 1.4

The monitor provides one USB-C port with DisplayPort Alt Mode, three HDMI 2.0 inputs and one DisplayPort 1.4 connection for multi-source workflows. HDMI 2.0 bandwidth restricts 4K 3840x2160 signals to lower refresh rates compared to newer interface versions. DisplayPort 1.4 offers higher throughput but still caps maximum resolution and refresh combinations that demanding imaging applications might require.

Installation and common issues

The anti-glare low-reflection coating reduces ambient light interference in bright clinical settings without additional hardware. Users must run periodic self-calibration using the internal colorimeter to sustain DICOM GSDF accuracy over time. OLED technology carries a risk of permanent image retention if static user interface elements remain displayed continuously at high brightness levels.

Questions about this item

Which version of the ASUS HA3281A should I choose for a 31.5 inch 4K medical display?

The HA3281A is a single 31.5 inch 4K OLED model with 8 megapixel resolution, factory calibrated for DICOM Part 14 GSDF compliance and equipped with a built-in colorimeter for long-term accuracy.

What does the 0.1 ms response time mean for daily clinical use?

The 0.1 ms gray-to-gray response time ensures blur-free motion when scrolling through high-resolution scans or viewing real-time imaging, keeping fine detail sharp during fast navigation.

What does the DisplayPort 1.4 connection cap in practice?

DisplayPort 1.4 supports the full 3840×2160 resolution at 10-bit color depth, while the three HDMI 2.0 ports and USB-C with DP Alt Mode provide additional flexible connectivity for medical workstations.
