They’re here!

After being shown at CES 2025, the new wave of 4K QD-OLED monitors is fast approaching the market. Most will be similar, but the Asus ROG Swift OLED PG27UCDM stands out from the pack with a couple extras, like ELMB black frame insertion for better motion clarity at lower refresh rates, and a USB-C port with 90 watts of Power Delivery. It’s a fantastic monitor, though certainly a bit pricey at MSRP.

Read on to learn more, then see our roundup of the best 4K monitors for comparison.

Asus ROG Swift OLED PG27UCDM specs and features

The most important feature of the Asus ROG Swift OLED PG27UCDM is, of course, the OLED panel. It’s part of a new generation of Samsung QD-OLED display panels that provide 4K resolution up to 240Hz.

• Display size: 26.5-inch 16:9 widescreen
• Native resolution: 3840×2160
• Panel type: 10-bit QD-OLED
• Refresh rate: 240Hz
• Adaptive sync: AMD FreeSync Premium Pro and G-Sync Compatible
• HDR: Yes, VESA DisplayHDR 400 True Black Certified
• Ports: 1x DisplayPort 2.1 UBHR20, 2x HDMI 2.1, 1x USB-C with DisplayPort Alternate Mode, 1x USB-C 3.2 Gen 1 with 90 watts of Power Delivery, 2x USB-A 3.2 Gen 1, 3.5mm audio jack
• VESA mount: 100x100mm
• Audio: None
• Price: $1,099.99 MSRP

Asus adds a few extras to help the monitor stand out, including an ELMB black frame insertion mode that I’ll discuss more in the motion clarity section of this review. The monitor also has 90 watts of Power Delivery over the USB-C port and includes a tripod mount at the top of the monitor stand for attaching a camera or ring light.

The monitor will hit stores with an MSRP of $1,099.99. That’s a high price for a 27-inch 4K monitor. However, other 27-inch 4K QD-OLED monitors will debut at the same price.

Asus ROG Swift OLED PG27UCDM design

The Asus ROG Swift OLED PG27UCDM’s design is typical for an Asus gaming monitor. It has a black charcoal look with aggressive styling, including a twisted, tripod-style monitor stand that takes up entirely too much space on your desk. Because of its depth, the stand forces the monitor closer to your face than you might want, especially if you have a smaller desk. I’ve never been a fan of this design and I’m becoming more critical of it as Asus’s competitors switch to flat stands that aren’t as annoying.

Still, the ROG Swift PG27UCDM is a nice-looking monitor if you don’t care how much space the stand takes up. It has multiple LED accent lights—one on the rear of the panel and one facing downward from the display stand—to add flair to your gaming setup. Asus’s material quality is high, giving the monitor a premium feel when you lift or adjust it. Speaking of adjustments, the stand provides ergonomic adjustments for height, tilt, and swivel. This is typical for any monitor in this price range but still good to see.

If you decide to replace the stand, you can use a standard 100x100mm VESA mount. Unlike most competitors, Asus’s monitor requires use of an included bracket to attach the panel to a third-party monitor arm or stand. It’s not a huge issue but worth keeping in mind, since it slightly complicates use with an arm (and you’ll want to keep track of that bracket).

 Asus ROG Swift OLED PG27UCDM connectivity

Asus doesn’t pull any punches when it comes to the ROG Swift OLED PG27UCDM’s connectivity. The monitor has a DisplayPort 2.1 port with UHBR 20, supporting up to 80Gbps of bandwidth. In addition to that, it has two HDMI 2.1 ports and a USB-C port with DisplayPort Alt Mode, making for a total of four inputs—all of which can handle the monitor’s maximum refresh rate and resolution.

The USB-C port provides up to 90W of Power Delivery. That’s not unique, as many of the new 4K 240Hz QD-OLED monitors offer USB-C. Some, like the MSI MPG 272URX QD-OLED, even provide slightly more power (the MSI goes up to 98 watts).

Even so, the USB-C port is useful. It connects to three downstream USB ports, making the ROG Swift OLED PG27UCDM a handy hub for a wired keyboard and mouse. There’s also a USB-B upstream input for connecting a device without USB-C, like a Windows desktop, to the monitor’s USB ports. The monitor has KVM switch functionality, too.

Asus ROG Swift OLED PG27UCDM features

PG27UCDM’s image quality options are extensive. It has multiple image quality preset modes alongside numerous color temperature and gamma options. The color temperature and gamma options target specific values, as well, instead of vague labels (for example, the menu lists a default color temperature of 6500K instead of “Normal”). The on-screen menus are easy to use and Asus provides a decent software utility, DisplayWidget, which can adjust most settings within Windows.

The monitor also has a uniform brightness mode, which can help tame the visible brightness fluctuations that can occur when viewing both very dark and bright windows. A proximity sensor is included and can dim the display automatically when you step away (which is meant to reduce the risk of OLED burn-in). The monitor also has adjustable HDR brightness, a nice-to-have feature not commonly found on competitive OLED displays.

There are plenty of features aimed at gamers, too. These include aspect ratio control modes which can support either a 4:3 aspect ratio or limit the viewable display space to mimic a 24.5-inch widescreen monitor (the type commonly used for esports tournaments). Gamers will also find the usual on-screen features including a crosshair, timer, frame rate display, and a dark equalization mode (called Shadow Boost) that makes foes lurking in shadows easier to see.

Speakers, on the other hand, aren’t included. While a bit disappointing, this is typical for a 27-inch OLED monitor. 

Asus ROG Swift OLED PG27UCDM SDR image quality

SDR image quality is a priority for the Asus ROG Swift PG27UCDM, as it is with any OLED gaming monitor. Fortunately, the 4K QD-OLED panel holds a lot of promise. It delivers the excellent color performance of prior QD-OLED displays but with a much higher pixel density. The result is a sharp, vivid image that looks gorgeous in a wide range of SDR content.  

Matthew Smith / Foundry

First up is SDR brightness, and here there are no surprises. The Asus ROG Swift PG27UCDM is a bit brighter than average for a QD-OLED monitor, but we’re still talking well under 300 nits at its maximum brightness. Even so, that’s more than enough for most gaming dens or home offices.

If you need a monitor for a bright sunroom or a corporate bullpen, however, the PG27UCDM can look a little dim. The same is true for other QD-OLED monitors, whereas IPS LCDs in this price range typically exceed 400 nits and are a much better choice for brightly lit rooms.

The PG27UCDM also has a glossy display panel finish. Though reasonably effective at reducing indirect screen glare, it will show obvious, crystal-clear reflections when bright objects are opposite the display.

Contrast is predictably amazing. The Asus ROG Swift PG27UCDM’s OLED panel can achieve a minimum luminance of zero nits, which results in excellent contrast across a wide variety of scenes. The image is deep, immersive, and provides a good sense of dimensionality that draws the eye into the image.

The same is true for other OLED monitors, so the PG27UCDM has no advantage here. Contrast is only an advantage if comparing the monitor to an LCD alternative.
