With Nano IPS, a layer of <2nm nanoparticles is applied to the standard W-LED backlight. These absorb certain unnecessary wavelengths of light like yellow and orange for more accurate red shades.

According to LG, this gives similar results to QLED, produces vivid, bright and saturated colours and allows borderless panels (just the bottom is edge-lit).


Claim 1300:1 but closer to 1200:1 (uniformity compensation enabled).


Claim 450/750 typical/peak. We measured 405nits typical with a 100% screen fill in Standard Dynamic Range (SDR) and 440nits with HDR content. This is fine for office lighting conditions.

Its VESA HDR600 certification requires it reaches 600 nits peak luminance on small areas of the screen and at least 350 nits for the duration.

Local dimming – ‘101’

First, let’s not confuse this 101 with TVs – it is about smaller monitor panels.

‘Local dimming’ is a prolific marketing term, and people confuse that for the vastly better and expensive ‘Full Array Local Dimming’ (FALD).

Edge-lit local dimming divides the screen into zones, typically as few as eight to sixteen. The light from the bottom edge LED lighting gets to these via a fibreoptic mesh. The monitor processor and graphics card GPU can then brighten the lighter areas of an image while darkening the darker areas to give an HDR effect (video experts call that HDRn’t).

With FALD, the screen has far more zones (hundreds to thousands), each with a LED backlight behind it. These are ‘direct-lit’ as opposed to ‘edge-lit’. FALD is the only technology that can achieve 1000+nits. You can use it with Nano IPS, and QLED overlays and these monitors are generally twice the price. They are also thicker and heavier.

This monitor is edge-lit with local dimming zones (we suspect eight) that sees some bloom on fast moving objects as they cross zones. Uniformity mode improves grey scale reproduction, and it works well. Black uniformity is not as good, but you can play with a black stabiliser setting if using HDMI input.

Viewing angle and colour shift

178° vertical and horizontal off-axis is a theoretical maximum. The reality is that premium edge-lit IPS (and this is) can handle 80° horizontal axis and 60° vertical axis without noticeable colour change.

Uniformity of colour and brightness

We did not notice any light wash or bloom from the lower edge – just a fairly the typical uniform IPS glow in a dark room. This is a first-rate screen with uniform colours within the viewing confines of desktop use.

10-bit colour – over 1 billion colours

It is an 8-bit+FRC (frame rate control) to upscale 8-bit to 10-bit. It has an excellent colour gradient, and in colour bar tests have no row or column pixel bleed.

While this is a ‘stock’ shpt colours are this good.


Anti-glare 3H (3 Haze) means great reflection control in an office environment (400-600 lumens).

PWM (Pulse width modulation)

It is a 60Hz (50Hz in Australia) refresh rate supporting both Radeon FreeSync and NVIDIA Adaptive Sync.
