Nio 3MP (MDNG‑3421CN)

3MP diagnostic grayscale display system

Nio 3MP (MDNG‑3421CN)

3MP diagnostic grayscale display system

  • High brightness to see more detail
  • Automated Quality Assurance and calibration 
  • Fully-tested system solution 

Nio® 3MP is ideal for high-quality imaging of diagnostic grayscale modalities. This display system comes with LED backlights for higher brightness and a unique front-of-screen sensor for excellent image quality at all times. These and other innovative features make your image look the best it can. 

Confident reading 

Equipped with high-bright LED backlights, Nio 3MP delivers excellent brightness and more shades of gray to detect subtle details more quickly. The unique front-of- screen sensor ensures you see consistent and precise images, calibrated at 500 cd/m², for confident diagnoses. 

On-demand image quality checks 

The front-of-screen sensor on Nio 3MP, which works seamlessly with Barco's online MediCal QAWeb solution for automated Quality Assurance and on-demand calibration, makes sure you are viewing perfect DICOM images. 

Improved productivity

The Nio 3MP includes seamlessly integrated technologies and features to boost functionality and performance so you can easily take control and improve your productivity. SpotView™, for example, allows you to focus on an area of interest to unveil even more details. And with DimView™, any auxiliary displays can be automatically dimmed. 

An excellent investment 

Using energy-efficient LED backlights, Nio 3MP is as low in power consumption as it is high in brightness. Because it uses less power, the display produces less heat and requires less cooling, which impacts maintenance and operational costs. Additionally, the LED backlights offer a long lifetime - even at high brightness - providing an excellent return on your investment. 


  • Front sensor and QAWeb for easy DICOM compliance 
  • High brightness unveils more details in the image 
  • Lowest cost of ownership
