Asus ROG Strix XG27AQDMG Announced with a Glossy OLED Panel

Share this content

It seems that the Asus ROG Swift PG27AQDM wasn’t the “end game” monitor it was marketed to be at the time, as Asus are now launching an updated model with similar spec and capabilities, and a few new features. The XG27AQDMG is a new model in their ROG Strix line-up, offering a 27″ OLED panel with a 1440p resolution and a 240Hz refresh rate. After the confusion at CES around their upcoming PG27AQDP 480Hz OLED monitor and it’s screen coating finish, what makes this new XG27AQDMG screen particularly interesting is that it does have a glossy screen coating – something which people have been screaming out for!

Asus ROG Strix XG27AQDMG Specs

The XG27AQDMG is 27″ in size (more accurately 26.5″) and has a flat format panel. It has a 2560 x 1440 resolution, 0.03ms G2G response time, 1.5 million:1 contrast ratio, 178/178 viewing angles, 10-bit colour depth and a wide colour gamut covering 99% of the DCI-P3 reference space.

ELMB (Extreme Low Motion Blur) has been added to this screen as well, and should operate at 120Hz refresh rate, half the native refresh rate of the panel, through a black frame insertion (BFI) approach like their PG32UCDM did (and other forthcoming Asus screens). This is a new feature that was not available on their previous PG27AQDM model.

As with other Asus OLED monitors the screen has a a custom heatsink and so does not need any active cooling fans. A comprehensive set of OLED care features are included, and it is backed by their 3 year warranty which includes burn-in cover too.

The stand has a new compact design with a small footprint, and supports tilt, height, swivel and rotate adjustments. For connectivity there are 1x DisplayPort 1.4 (with DSC), 2x HDMI 2.0 and 2x USB data ports available. There is also a headphone jack connection.

HDR capabilities

The screen has been certified under the VESA ‘DisplayHDR 400 True Black’ tier and uses a panel from LG.Display’s latest generation which should have a peak brightness of over 1000 nits in HDR. LG.Display themselves promote these panels as reaching 1300 nits for peak white luminance in HDR, but Asus have been a little more conservative with their promotion of these specs including on the 34″ PG34WCDM which also featured one of these newer panels.

Clear pixel edge

Asus also promote their “clear pixel edge algorithm” which is designed to help improve text clarity on these WOLED panels, although we didn’t find this offered much real benefit when we tested the ROG Swift PG34WCDM previously. Note that the 27″ panel used in this new screen still has the older RWBG pixel structure, like the PG27AQDM and other 27″ WOLED monitors. It does not have the newer sub-pixel layout of some of the other forthcoming LG.Display WOLED panels.

Reduced VRR flicker

The screen has a 240Hz refresh rate and supports adaptive-sync for VRR form compatible systems. It has been certified under the NVIDIA ‘G-sync Compatible’, AMD ‘FreeSync Premium’ and VESA ‘AdaptiveSync 240’ schemes.

Interestingly Asus state that the screen will include “ROG-exclusive OLED Anti-flicker technology [which] helps reduce the flicker during refresh-rate fluctuations”. This is actually something they’ve very recently added to their ROG Swift PG27AQDM model too via a firmware update (MCM106), so it will be interesting to see what impact and improvement this has on potential VRR flicker on these panels. It looks like this screen will have settings for strong, middle and off for this anti-flicker option.

Glossy screen coating

The display uses an LG.Display WOLED technology panel with a glossy coating finish. This is one that we have reported on in the past as being in development from LG.Display in our various roadmap updates (latest one here). From the Asus promotional video and product page, it appears that this new glossy coated panel may be an exclusive to Asus for the time being, but we may see other competing screens in the future with this coating perhaps. At the moment we know of only this 27″ panel with a glossy coating in development from LG.Display, there’s no news on other sizes and specs at this time. Although if it proves popular, there could well be others developed later on.

We don’t have much information about this coating at the moment, but it is possible (perhaps likely) that it is similar to the glossy coating that LG.Display use for their TV panels. It looks like the coating will be applied at source from the panel manufacturer, as opposed to being added on later on top of the standard matte coating by the display manufacturer as some other brands are doing to create a glossy glass finish (e.g. Dough). If it is similar to their TV panel glossy coating this could help with black depth levels as we studied in detail here, as this coating finish out-performed matte, semi-glossy and gorilla glass (the Dough glossy approach) in terms of black depth in our testing. However, as a trade-off it is likely that it would have higher levels of glare and reflections compared with other coating approaches. We will have to wait and see the screen in action to understand more about its coating finish, black depth performance and reflection handling.

20% higher luminance for SDR

Asus also promote the screen having a “20% higher brightness” (they actually mean luminance) for SDR 100% APL situations, as compared with their previous PG27AQDM model. This is made possible through the use of LG.Display’s latest generation of 27″ WOLED panel. Asus don’t actually listed a luminance spec, but by our calculations based on the testing of the PG27AQDM which could reach ~259 nits in SDR, it should be able to reach up to around 311 nits. The screen supports their familiar uniform brightness mode for desktop use too.

Pricing and availability

Update 30/5/24 – the screen is being released in the USA on 30th May 2024 at an MSRP of $749 USD, although there is also going to be a launch exclusive price of $699 USD via Newegg (now available) and some other select stores.
