HealthCare Monitor
ASUS HealthCare Displays provides comprehensive line-up targeting for every HealthCare institutions needs. ASUS HealthCare Displays are factory calibrated with DICOM® Part 14 GSDF (Grayscale standard display function) compliance to ensure visual accuracy and consistency in finest details. ASUS HA3281A features 31.5-inch 8MP Anti-Glare, Low-Reflection (AGLR) pure RGB OLED panel, built-in colorimeter supports self / auto calibration to keep DICOM long term accuracy. ASUS HealthCare Displays delivers high-performance, precise and stable capabilities to fit any scenario.
Premium OLED panel with RGB stripes
ASUS HA3281A incorporates OLED technology which achieves ultra-precise control and extreme contrast by making each individual pixel its own light source. HA3281A has a pure RGB Stripe OLED panel with billions of self-illuminating pixels that can be individually activated to reproduce excellent contrast, ensuring the accurate and clear medical images.
Factory-Precise for DICOM Excellence
To provides reliable images and stable grayscale, ASUS HealthCare Displays compliant with the Digital Imaging and Communications in Medicine (DICOM) Part 14 GSDF standard, and also pass AAPM TG270 and TG18 compliance test.
Each ASUS HealthCare display is factory calibrated to guarantee DICOM color accuracy. The display then undergoes stringent testing to ensure smoother color gradations, better uniformity with Just-Noticeable Difference (JND) <10%.
