Asus Provide Update on ROG Swift PG32UCDM with 32″ QD-OLED Panel, 4K and 240Hz

Share this content

Originally launched at the 2023 Gamescom event in August 2023, Asus have provided a recent update about their forthcoming 32″ 4K 240Hz OLED gaming monitor, the ROG Swift PG32UCDM. We now know from an updated press release that this screen will feature support for Dolby Vision HDR content, something that we’ve seen announced on other recent OLED screens too, and it’s great to see this format now supported in the monitor space. More information below on the scree

First Impressions, Summary and Thoughts Video

We had chance to see the screen in person at Gamescom, and our thoughts and information from that event are in the video below:

Asus ROG Swift PG32UCDM Specs

The new screen is 32″ in size (accurately 31.5″) and has a 3840 x 2160 “4K” resolution. There is a high 240Hz refresh rate too, with adaptive-sync supporting variable refresh rates (VRR) from compatible NVIDIA and AMD systems. It includes certification under the AMD ‘FreeSync Premium’ and NVIDIA ‘G-sync Compatible’ schemes as well to give some reassurance around VRR performance. The screen has a quoted 0.03 ms G2G response time spec as well since it’s an OLED panel, with near-instant response times inherent to this technology.

HDR Capabilities including Dolby Vision

The peak brightness for HDR is rated at 1000 nits (3% APL), dropping to 400 nits for 10% APL and 250 nits for 100% APL. The OLED panel offers the usual benefits of per pixel dimming (so no blooming or halos), true blacks and near-infinite contrast ratio. The screen will also meet the VESA ‘DisplayHDR 400 True Black’ tier, not to be confused with the normal HDR400 tier for LCD monitors. In SDR mode the screen should also offer a 250 nits full screen (100% APL) brightness, with a uniform brightness mode offering stable brightness and no need for ABL dimming, like we’ve seen on previous Asus OLED displays.

Dolby Vision support is included, with the press release stating: “we equipped it with support for Dolby Vision. Plenty of 4K Blu-rays support this dynamic HDR format, and many video streaming services like Netflix, Amazon Prime Video, Disney+, and Apple TV+ have a broad selection of Dolby Vision content. In one display, you’ll have high-end HDR gaming and premium HDR entertainment alike.”

Custom heatsink and graphene film rear panel

As with previous Asus OLED screens we’ve seen released like their 27″ 1440p 240Hz model, the Asus ROG Swift OLED PG27AQDM, the new display will feature a custom heatsink and “graphene film rear panel” which means it can operate without an active cooling fan, and which the company says should also help with lifespan and reduce the risk of image retention.

Asus explain more about Graphene film by saying it’s “the thinnest yet strongest nanomaterial in the world, graphene has a thermal conductivity coefficient of up to 5,300 W/mk — a figure more than a hundred times greater than silver, copper, gold, or aluminum can offer. The lower operating temperatures offered by this cooling solution allow the display to produce and sustain high peak brightness levels.”

QD-OLED “semi glossy” panel coating

Like other QD-OLED panels released to date, the screen features the normal Semi glossy coating type, with a cleaner and clearer image than matte coating used on some other OLED panels (including their 27″ OLED PG27AQDM which uses an LG.Display WOLED panel). This isn’t to everyone’s taste, but a lot of people do prefer the cleaner image, especially as the monitor sized WOLED panels actually had a more aggressive and grainy coating than normal matte coatings used in the monitor market.

One thing to note though is that the lack of a polarizer on the panel means that in some lighting conditions you do get a reduced perceived contrast and black depth, more so than on WOLED panels. This is a drawback of current QD-OLED offerings, although these panels are always better if you can use them in darker rooms anyway.

Third Generation QD-OLED Panel Benefits

The ROG Swift PG32UCDM offers a 31.5″ screen size and will be built around Samsung’s forthcoming 3rd generation QD-OLED panel which we discussed in our recent video here. This will include the somewhat improved sub-pixel layout that helps improve text clarity a bit and so along with the higher pixel density of the 4K resolution, should offer very good text clarity.

We experienced this new layout in the Samsung Odyssey OLED G95SC and Asus ROG Swift PG49WCD displays we reviewed (49″ super ultrawide) and found it improved compared with the first gen panels, like that used in the wide range of 34″ models on the market like the Dell Alienware AW3423DW for instance.

Connectivity options

The PG32UCDM will offer DisplayPort 1.4 (with DSC), HDMI 2.1 (capabilities not listed) and USB type-C (with DP Alt mode and power delivery). A KVM function is also supported along with PiP. There are also 2x USB data ports, a headphone connection and an SPDIF audio output offered.

Pricing and Availability

The updated press release from 9th January 2024 says that “Currently, we plan to make this monitor available for sale early in 2024. For more information on the pricing and availability of the ROG Swift OLED PG32UCDM in your region, please contact your local ROG representative.”

Asus also have their other 32″ 4K 240Hz OLED monitor planned for later in the year using LG.Display’s WOLED panel instead, and offering “dual-mode” support. More info on that alternative model here.
