LG 34UC89G UltraWide 166Hz IPS with G-SYNC

With its 144Hz IPS panel and UltraWide aspect ratio, the LG 34UC79G generated a lot of interest amongst gamers. One notable missing feature for those with Nvidia GPUs, though, was support for their G-SYNC variable refresh rate technology. The LG 34UC89G (also referred to as the 34UC89G-B owing to the black rear) sets to redress this balance. From the front the monitor is as good as indistinguishable from the older 79G, which isn’t necessarily a bad thing as many users found the style to be quite agreeable. Dual-stage ‘cinema screen’ bezels feature, with a very slim hard plastic outer border and a dark grey inner panel border. The OSD (On Screen Display) is controlled by a small JOG button or joystick towards the right of centre, facing downwards. As is now common on LG monitors, you can control the OSD using the included ‘OnScreen Control’ software. This also includes ‘Screen Split’, which allows users to organise windows in various ways on the desktop with ease. This sort of functionality is now built into newer versions of Windows, but by using ‘Screen Split’ you can set application-specific preferences and don’t need to drag windows around the screen to snap them into your preferred position.

Unfussy aesthetics

The monitor uses a 34” LG AH-IPS (Advanced High Performance In-Plane Switching) panel with 2560 x 1080 resolution (21:9 UltraWide aspect ratio). The panel natively supports a 144Hz refresh rate but is overclockable to 166Hz, with support for Nvidia G-SYNC (30 – 166Hz variable refresh rate). Whilst some users may baulk at the 2560 x 1080 resolution, preferring the pixel density of something like 3440 x 1440 on a 34” screen, it is considerably easier on the GPU and therefore easier to run the monitor at nice high frame rates. Coupled with G-SYNC, which allows the monitor to match its refresh rate with the frame rate of a game, this certainly has the potential to deliver a very fluid experience. Other aspects of the panel to note include a 1000:1 specified response time, 178°/178° viewing angles and a light matte screen surface. This all helps deliver an image that is consistently rich across the screen, avoiding the viewing angle related pitfalls of other panel types. The screen also has a subtle curve to it at 3800R – something we feel adds just a little extra depth to the experience and feels completely natural and very easy to ‘adjust’ to. True 8-bit colour is supported, whilst a flicker-free (DC dimming not PWM) WLED backlight is used offering sRGB colour support but no extended gamut support. A 300 cd/m² typical maximum brightness is specified.

A 5ms grey to grey response time is specified, which should be taken with the usual pinch of salt. DAS (Dynamic Action Sync) also features, which is simply the name given to LG’s low input lag mode that minimises extraneous processing and hence minimises signal delay. This is something all G-SYNC models do anyway, but the manufacturer certainly likes to hammer home that low latency is being focussed on here. Additional features include ‘Black Stabilizer’ which is a gamma enhancement feature that lightens dark shades to increase the visibility or enemies (or whatever else) in dark areas. There is also an onscreen crosshair feature and a ‘Reader’ mode Low Blue Light (LBL) setting for relaxing viewing, particularly useful in the evening. There is no mention of ULMB (Ultra Low Motion Blur) or any alternative strobe backlight mode in the product specifics that are currently available, so we will assume that there isn’t such a thing. The included stand offers tilt adjustment (5° forwards, 20° backwards) and height adjustment (120mm or 4.72 inches). It can be removed to make way for an alternative 100mm VESA compatible stand or mount. The ports include; DP 1.2 (supports G-SYNC), HDMI 1.4 and 2 USB 3.0 ports.

A little red at the rear

Further details can be found on the manufacturer’s website. The monitor is expected to be available globally in July or August, with a $999 RRP. We will request a review sample and would like to review this, but we can’t promise anything.
