LG 34UC79G 144Hz IPS UltraWide model
Recent trends in the 21:9 UltraWide market have included a combination of ‘overclocked’ IPS models, running at up to 100Hz. And of course VA models ‘running’ at up to 200Hz without really offering offering sufficient pixel responsiveness to support this properly. The LG 34UC79G (also known as the 34UC79G-B due to the matte black colouration) offers something a bit different – a native 144Hz AH-IPS panel. This marks the first time LG AH-IPS panels have run at such refresh rates, a welcome transition for many users no doubt. The top and side bezels of this screen are moderately thin (but not super-thin) with a matte black bottom bezel and matching matte black (metallic-looking) stand. There is also a dark red ‘join’ where the stand base and neck meet. The included stand offers tilt adjustment (5° forwards, 20° backwards) and height adjustment (120mm or 4.72 inches). A JOG button (joystick) allows convenient OSD (On Screen Display) navigation.
The panel used is a 34” LG AH-IPS part with 2560 x 1080 resolution (21:9), 144Hz refresh rate (50Hz – 144Hz variable, with Adaptive-Sync) and a fairly gentle 3800R curve. This curvature is similar to the original 34” curved IPS models, so a lot less steep than some of the more recent curved displays. The support for ‘Adaptive-Sync’ means that AMD GPU users can make use of the FreeSync variable refresh rate technology, if their GPU is compatible. Some users will of course be disappointed by the 2560 x 1080 rather than 3440 x 1440 resolution, which means the pixel density is similar to a 27” Full HD model rather than 27” WQHD model. However; it does make it easier to maintain high frame rates and allows the monitor’s full functionality to be used on DP 1.2 rather than relying on newer standards such as DP 1.3 or DP 1.4. Other aspect to note include a light matte screen surface, 1000:1 static contrast ratio, flicker-free WLED backlight with 300 cd/m² typical luminance and 8-bit colour (likely without dithering).
A 4ms grey to grey response time is specified whilst a ‘Motion Blur Reduction’ strobe backlight mode also features. This can’t be used at the same time as FreeSync, but offers an alternative operating mode for the monitor for both AMD and Nvidia GPU users. Additional gaming-oriented feature includes DAS (Dynamic Action Sync), a ‘though-mode’ to minimise extraneous processing and hence cut input lag. There is also ‘Black Stabilizer’, a gamma enhancement feature which artificially enhances detail in dark areas at the expense of accuracy to improve visibility. There is also an on-screen crosshair function and an integrated 1:1 pixel mapping function.
The rear of the monitor shows a number of dark red elements on the stand – which for most users, will be for their wall to enjoy. It appears matte black plastic is used elsewhere. The included stand can be removed to reveal 100 x 100mm VESA holes. The ports of the monitor are backwards-facing in a recessed area and include; DP 1.2a (with Adaptive-Sync), 2 HDMI ports, 2 USB 3.0 ports (one with fast-charging), USB upstream, 1.2mm audio input and 3.5mm audio output. A DC power input is also included, meaning an external ‘power brick’ is used.
Further details can be found on various regional LG websites (including this one, in German). Ignore any mention of ‘3440 x 1440’ – this is incorrect. This model is available to pre-order in the US for under $700 and is expected to launch in regions including the US and UK shortly. We hope to review this model as well.
