Flanders Scientific XM312U

The XM312U is the next evolution of our HDR monitoring options and offers several key advantages over our outgoing XM310K, including:

  • Over 2,000nits brighter peak luminance
  • 20% improvement in backlight zones to pixels ratio
  • Twice the panel static contrast ratio​​​​
SKU: XM312U Category: Tag:


The XM312U is a 31″ UHD resolution HDR and SDR reference master monitor equipped with professional 12Gbps SDI inputs. The XM312U qualifies as a Dolby Vision mastering monitor. A peak luminance over 5,000cd/m2, support for both PQ and HLG EOTFs, multiple color gamut selections, and a contrast ratio in excess of 5,000,000:1 make the XM312U ideal for a wide variety of demanding HDR workflows.

Many professional HDR displays have a peak luminance of just 1,000nits. With a peak luminance over 5,000nits, the XM312U is five times brighter making it one of the brightest commercially available professional HDR monitors.

The XM312U achieves this with a full array local dimming backlight with over 2,300 individually controlled LED elements. Compared to the award-winning XM310K that it replaces, the XM312U features a 20% improvement in the ratio of backlight zones to pixels, twice the panel static contrast ratio, and a peak luminance that is over 2,000nits brighter. These advancements combine for a truly unparalleled HDR viewing experience.
