NEC’s MultiSync PA311D, a 10-bit IPS 4K Professional Monitor

NEC this week introduced a new professional display for color critical applications. The NEC MultiSync PA311D LCD features a 4K resolution, covers 100% of the AdobeRGB color space and is aimed at people working with computer graphics, video, and photography. The monitor supports sophisticated connectivity, including a USB-C input that supports 65 W power delivery.

The NEC MultiSync PA311D LCD display is based on a 31.1-inch 10-bit IPS panel with a true 4K resolution of 4096×2160. Combined with its wide gamut W-LED backlighting, that can reproduce 1.07 billion colors across 99.9% of the sRGB, 97.4% of the NTSC, and 100% of the AdobeRGB color gamuts. The monitor features a peak luminance of 350 nits, a 1400:1 contrast ratio, an 8 ms typical response time, and unusual for a pro grade monitor, a top refresh rate of 75Hz.

Being aimed at professionals, the monitor uses NEC’s custom color processor and comes with a 14-bit 3D LUT (look-up table) for color gradations. NEC has also implemented an always-on backlight sensor here, in order to offer steady colors and brightness levels. And of course, monitor calibration is supported through the company’s SpectraView II calibration software (with a color sensor sold separately or as a part of an appropriate bundle).

One unexpected capability of the monitor is that it is touch capable, and it comes with an appropriate stand that can adjust height, tilt, swivel, or change the LCD’s orientation.

The pro monitor also offers a few different input options. The monitor has two DisplayPorts, two HDMI ports, and a USB Type-C connector, the latter of which is still relatively new to professional LCDs. The USB-C port can deliver up to 65 W of power to its host PC, which is enough for most 13 and 15-inch class laptops. In addition, the display has a GbE jack, a 3.5-mm jack for headphones, and a triple-port USB 3.0 hub with two USB Type-B upstream ports.
