Asus Announce the ROG Strix XG34WCDMS with a 34″ ultrawide 280Hz 5th Gen QD-OLED Panel

Following on from the announcement of their flagship ROG Swift PG34WCDN monitor today (news piece here | full review here), Asus have also announced a new model in their ROG Strix line-up, the XG34WCDMS. This is another 34″ ultrawide model featuring a new 5th Gen QD-OLED panel, this time with a lower 280Hz refresh rate and a more modest feature set. Like the PG34WCDN it features the latest RGB-stripe pixel layout for improved text and image clarity, and a ‘BlackShield Film’ coating for improved blacks and scratch resistance.

5th-Gen QD-OLED Panel and ‘BlackShield Film’

We are especially exciting to see Samsung Display’s new 5^th-Gen Tandem QD-OLED panel technology being utilised in this model as part of their 2026 panel line-up. Note that Samsung Display don’t like to refer to their panels by generation any more, but there are significant changes here which warrant this ‘Gen 5’ naming scheme which we’ve used.

This new panel features for the first time a true RGB stripe pixel arrangement (which Samsung Display are calling “V-stripe”), enhancing the image and text clarity and eliminating fringing issues that have impacted earlier QD-OLED monitor panels.

The screen also includes what Asus are referring to as a ‘BlackShield Film’ coating which helps deliver deeper blacks in brighter room conditions and reduce the purple tint that impacts older panels. This is actually a coating applied by Samsung Display at the panel level, with the ‘BlackShield Film’ being Asus’ branding name for it – much like MSI are calling it ‘DarkArmor’ for their equivalent monitors.

The panel hardness has also increased from 2H to 3H, offering better scratch resistance and durability. This new coating also features on their recently announced 32″ QD-OLED monitor for 2026, although note that those models did not have the new V-stripe / RGB stripe sub-pixel layout.

For loads more information on the new panel developments please check out our full review of the ROG Swift PG34WCDN model which provides a lot more detail about how this panel measured up in our testing.

The new 5th Gen QD-OLED panel also offers enhanced brightness thanks to the use of their latest EL 3.0 OLED material (also featured on their 4th Gen panels), with a 300 nits SDR luminance and True Black 500 certification for HDR. It also includes for the first time an increased peak brightness spec of 1300 nits in HDR.

ROG Strix XG34WCDMS Specs

This 34″ ultrawide sized screen has a subtle 1800R curvature. It features a 3440 x 1440 resolution, 21:9 aspect ratio, 0.03ms G2G response time spec, 1.5 million:1 contrast ratio, 300 nits brightness (SDR), 178/178 viewing angles, 10-bit colour depth and a wide colour gamut covering 99% of the DCI-P3 colour space. It also offers a factory calibrated Delta E<2 accuracy.

This model has a slightly lower 280Hz refresh rate compared with 360Hz on the PG34WCDN model, and this is supported by adaptive-sync for variable refresh rates from compatible systems. It has improved HDR capabilities with certification under the VESA DisplayHDR True Black 500 tier along with an improved peak brightness spec of 1300 nits.

The monitor also features DisplayPort 1.4 (with DSC), HDMI 2.1, and USB type-C (with DP alt mode and 15W Power Delivery) connections. A compact stand with a minimal footprint enables users to free up more desk space for other peripherals.

Availability and pricing

No word on pricing and availability yet, although we’d expect to see this released during Q1 like the PG34WCDN. More info from CES soon.
