LG Shows Dual Colour Spaces

By Tom Allen

We have learned more about LG’s high-resolution LCD monitor, shown at NAB this year (LG Needs Thunderbolt for DCI-4k): the 31MU97Z.

As well as DCI-4k resolution (4096 x 2160, 17:9), the 10-bit display features factory-calibrated colour and covers 99.5% of Adobe RGB and 97% of DCI-P3. A dual-colour feature enables the screen to be partitioned; one half will show content in Adobe RGB, and the other in sRGB.

LG’s monitor uses single stream transport to show a DCI-4k signal, rather than multi-stream (splits and recombines the signal) or tiled (stitches signals from multiple GPU input signals) transport. HDMI (x2), DisplayPort 1.2, mini-DisplayPort 1.2, Thunderbolt, USB 3.0 (x3) and USB-B inputs are featured.

Unlike the display that we saw at NAB, only a single Thunderbolt port is built in. However, the DisplayPort interfaces have been added, which can show DCI-4k content at 60fps; the HDMI ports will only support 24fps.

An IPS panel provides 178° viewing angles, a 5ms (grey-to-grey) response time and 1,000:1 contrast ratio. Brightness is 320 cd/m². An anti-glare treatment is applied to the front of the display. -5° – 15° tilt and 90° pivot are functions of the stand. Two 5W speakers are also installed.

LG is selling the monitor now, for $1,400.
