Now updated 18 June 2019: LG have announced the release of a new 27″ display in their UltraGear line-up, aimed at gamers. The 27GL850 (previously announced as the 27GL850G) will use a Nano IPS panel and offers a 2560 x 1440 resolution. The screen was originally expected to use a hardware G-sync module, but LG have now updated this model to instead be an Adaptive-sync supporting screen, including AMD FreeSync support and certified as “G-sync Compatible”. They’ve removed the “G” from the product name as well. Read on for an updated news piece about this screen.

This is a potentially interesting screen as until now there have only been high refresh rate IPS-type panels provided by AU Optronics (as used in the Asus ROG Swift PG279Q, Acer Predator XB271HU etc). We know from the LG spec page that the screen has a native 144Hz refresh rate. Sadly LG have had to drop the 160Hz overclocked refresh rate mentioned in the original press release, as they’ve changed it from a G-sync hardware screen (where overclocking is more readily supported) to an adaptive-sync display instead. This is the largest change LG have made to the screen since it was originally announced, dropping the “G” from the end of the name and changing it from a traditional G-sync screen (with hardware G-sync module) to a normal adaptive-sync screen. This does mean that it can also support variable refresh rates (VRR) from AMD FreeSync systems as well. To give reassurances to NVIDIA users the screen is also certified as “G-sync Compatible” for NVIDIA cards.

The use of the term ‘Nano IPS’ by LG implies it might use a latest generation LG.Display IPS panel as they’ve used this for other recent displays like the 34GK950F/G for instance, and it is used to signify a model with wide colour gamut as well. This is now confirmed on the spec page as offering 98% DCI-P3 gamut coverage (135% sRGB). It will be one of the first to offer this wide gamut with a high refresh rate in the 27″ IPS market.

Like the 37.5″ size 38GL950G model, the response time spec is listed as 1ms G2G which has apparently been evaluated by UL (Underwriter laboratories). They act as an external third party to test performance it seems here, although it remains to be seen whether this 1ms can be achieved reliably, across a good number of transitions or only in the most extreme examples. It also remains to be seen whether this is only possible in the maximum overdrive mode, and at the cost of very high overshoot. We will see for ourselves when we have chance to test this screen.

In other specs the 27″ sized screen offers a 2560 x 1440 resolution, 1000:1 contrast ratio, 350 cd/m2 brightness, 178/178 viewing angles, 1.07b colour depth.

HDR is “supported” in so much as it accepts an HDR10 input source. This model doesn’t carry any of the VESA DisplayHDR certifications as the peak brightness of 350 cd/m2 is not high enough to even meet the lowly HDR400 level. with no note of any local dimming support included sadly. We are still waiting on official pricing and release date information for this model.

The stand offers tilt, height and swivel adjustments while there are DisplayPort, 2x HDMI, 2x USB 3.0 and a headphone jack provided for connectivity.

There is further information available from LG’s product page. According to the recent press release “LG UltraGear Nano IPS gaming monitors are set to roll out next month, with pre-orders for model 27GL850 commencing in the United States on July 1 with availability in key European markets in the third quarter of this year.”
