LG 24GM79G 144Hz Full HD gaming monitor

The LG 24GM77 has been a popular choice for gamers looking for a ‘simple’ Full HD gaming experience at high refresh rates. The mixture of features, fairly well-tuned grey to grey acceleration and decent image quality after just a few tweaks was quite appealing. The LG 24GM79G (or 24GM79G-B, describing its black rear) is the successor to this model. Aesthetically it is rather similar, with a few tweaks including more subdued (dark red) button labelling and a matte rather than glossy stand base. The buttons control the OSD (On Screen Display) and are pressable rather than touch-sensitive. The monitor retains the somewhat chunky industrial look, owing in large part to the bezels being quite thick by modern standards. Something that is down to the design of the panels used, where ‘slim bezels’ never came into the equation.

An industrial design

The panel used is a 1920 x 1080 (Full HD) TN model capable of 144Hz – namely a variant of the AU Optronics M240HW01 now ubiquitous on 144Hz models of this size. This features a medium matte anti-glare screen surface and has a specified 1000:1 static contrast ratio and 170° horizontal. 160° vertical viewing angles. By simply specifying ‘8-bits’ for the colour depth, as they did with the 24GM77, LG will no doubt cause some confusion. To clarify – the panel used is 6-bit + FRC dithering rather than ‘true 8-bit’ and therefore so are the products that use it. The backlight is a flicker-free WLED unit offering ~sRGB colour space coverage and a specified peak luminance of 350 cd/m². Rather peculiarly a 5ms grey to grey response time is specified, unless the ‘1ms Motion Blur Reduction’ strobe backlight feature is employed. This could be to make the ‘1ms Motion Blur Reduction’ sound more impressive as a feature, for those who don’t understand the premise of strobe backlights and how they improve motion clarity. Alternatively, this model could employ more gentle grey to grey acceleration or simply have a more realistic ‘real world’ figure specified for the response time. There is a ‘Response Time Control’ feature that allows you to adjust this level of acceleration, however.

Other notable gaming features include Adaptive-Sync and hence support for AMD FreeSync on compatible GPUs, with a variable refresh rate range believed to be 48 – 144Hz but yet to be confirmed. There is also ‘DAS’ (Dynamic Action Sync), a though-mode to minimise extraneous image processing and hence minimise input lag. An on-screen crosshair feature is also present, as is the ‘Black Stabilizer’ feature which enhances visibility in dark scenes at the expense of image accuracy. The included stand offers height, swivel, tilt and pivot adjustment and attaches by 100 x 100mm VESA. It can be removed to make way for alternative mounting. The rear of the monitor is matte black plastic with some red ‘cheeks’ that are more obviously visible from the side. The left side of the monitor also houses a 3.5mm headphone jack and 2 USB 3.0 ports. The remaining ports face downwards and include; AC power input (internal power converter), 2 HDMI 2.0 ports (with Adaptive-Sync) and DP 1.2a (with Adaptive-Sync). There’s also a K-slot and cable tidy feature at the rear.

The practical rear

More information on the monitor can be found on LG’s official website. The monitor is due for global release very shortly with a street price of around $350 in the US. If there is sufficient demand we’ll consider reviewing this model, although we already have an unenviable backlog of monitors we’d like to look at.
