The Flanders Scientific 31" 4K HDR LCD Monitor with 12G/6G/3G/HD-SDI Inputs is a true 4K resolution HDR and SDR reference master monitor equipped with professional 12Gbps SDI inputs. A peak luminance of 3000cd/m2 (3,000nits, at L20) makes this the world's brightest HDR monitor. It is highly effective at grading and provides multiple scopes to enhance your content, support for both PQ and HLG EOTFs, multiple color gamut selections, and a contrast ratio in excess of 1,000,000:1, all of which make the XM310K ideal for a wide variety of demanding HDR workflows. The XM310K qualifies as a Dolby Vision mastering monitor.

On-Set Color Management

The XM310K features direct compatibility with on-set color applications like LiveGrade Pro, Prelight, FireDay, and FirePlay (not included) for real-time color manipulation without the need for a standalone 4K LUT box.

Multi-Cam Monitoring

The XM310K is ideal for multi-camera monitoring applications, with support for simultaneous viewing of up to (4) genlocked HD feeds and the additional ability to view any feed in full screen, as needed.


12Gbps SDI connections greatly simplify room design by allowing you to feed 4K and UHD signals to the display over a single cable. Quad 1.5Gbps and 3Gbps SDI connectivity are also supported in both 2SI and Square Division-based variations, ensuring compatibility with practically any type of 4K or UHD output. The XM310K supports advanced 12bit 4:4:4 YCbCr, RGB, and XYZ signals, setting it apart from less advanced monitoring solutions.

The XM310K features the unique ability to simultaneously supply a clean 12G / 6G loop-through and real-time downconverted 3G or 1.5G output. Any incoming single link 4K or UHD signals can be converted to 2K or HD outputs for downstream HD monitors or scopes, all without needing any standalone down conversion equipment.

Native 4K Resolution

The XM310K is a true 4K resolution (4096 x 2160) monitor that supports full screen viewing of HD, Ultra HD, and 4K content.


The XM310K is equipped with 4K compatible, real-time Waveform and Vector Scope functions.


Choose from a wide assortment of standard markers and safety areas that can be displayed as lines, translucent overlays, or solid overlays. Lines and overlays have selectable colors for instant customization.

Power Efficiency

The XM310K is power efficient, consuming just 80W in SDR mode and 200W maximum in HDR mode. The XM310K requires only a single power cable and can be plugged into any standard 110~240V AC outlet.

Durability & Compact Design

The XM310K is engineered to meet critical post production benchmarks for HDR mastering, but has also been designed with production applications in mind, with physical characteristics like recessed SDI inputs, 100mm VESA mounting compatibility, a durable all-metal chassis, and mounting points for a protective transport screen cover (not included).
