The ASUS ROG Swift OLED PG32UCDM is a 32-inch, 4k gaming monitor with a 240Hz refresh rate. Part of the Republic of Gamers (ROG) lineup, it competes alongside models from other brands that use the same third-gen QD-OLED panel, like the Dell Alienware AW3225QF, MSI MPG 321URX QD-OLED, and the Gigabyte AORUS FO32U2P. It has features you'd expect to find in a gaming monitor, like VRR support and HDMI 2.1 bandwidth, and ASUS advertises that it will receive Dolby Vision support with a future firmware update. It even has some extra productivity perks like a USB-C port with up to 90W of power delivery and a KVM switch that makes it easy to multitask with different computers. Lastly, it has features to prevent the risk of burn-in that OLEDs are known for, like a custom heatsink, OLED Care settings, and a three-year warranty against burn-in, although this can change across different countries.

Our Verdict

9.1 PC Gaming

The ASUS PG32UCDM is remarkable for PC gaming. It has a high 240Hz refresh rate, motion also looks extremely sharp thanks to its near-instantaneous response time, and it has low input lag at its max refresh rate. While the input lag increases with lower refresh rates, it isn't high enough that you'll really notice it. On the plus side, it delivers outstanding picture quality with deep and inky blacks, no blooming, and vivid colors. Though it supports all common VRR formats, it has noticeable VRR flicker with changing frame rates.

Pros
  • Near-instantaneous response time.
  • Displays deep and inky blacks.
  • 240Hz refresh rate and VRR support.
  • Low input lag at max refresh rate.
  • Bright and vivid colors.
  • Sharp text and image clarity.
Cons
  • Noticeable VRR flicker with changing frame rates.
  • Ambient light causes black levels to raise.
9.2 Console Gaming

The ASUS PG32UCDM is outstanding for console gaming. It takes full advantage of the PS5 and Xbox Series X|S thanks to its HDMI 2.1 bandwidth, and it offers sharp images as it has a 4k resolution. It also delivers outstanding picture quality with deep blacks and vivid colors, so your games look realistic and immersive. Lastly, motion is sharp as it has a near-instantaneous response time, and while its input lag at 120Hz and 60Hz is a bit higher than other monitors, it still feels responsive.

Pros
  • Near-instantaneous response time.
  • Displays deep and inky blacks.
  • Bright and vivid colors.
  • HDMI 2.1 bandwidth.
  • Sharp text and image clarity.
Cons
  • Input lag is a bit higher at 120Hz and 60Hz.
  • Ambient light causes black levels to raise.
8.2 Office

The ASUS PG32UCDM is great for office use, but there are some limitations. The 4k resolution helps deliver sharp text, and it has wide viewing angles that make it easy to share your screen with others. It also gets bright enough to fight glare and has fantastic reflection handling, but ambient lights cause blacks to look purple. Unfortunately, though, it has the risk of permanent burn-in with constant exposure to the same static elements over time, which is a problem if you're only using it for office work.

Pros
  • Bright enough to fight glare in most rooms.
  • Fantastic reflection handling.
  • USB hub and KVM switch.
  • Sharp text and image clarity.
Cons
  • Risk of burn-in.
8.9 Editing

The ASUS PG32UCDM is amazing for photo and video editing. You can edit your content with a ton of details thanks to its outstanding picture quality, as it displays deep and inky blacks, and the 4k resolution also helps deliver sharp images. It even displays a wide range of vivid colors, but you need to calibrate it for the best accuracy. While it gets bright enough to fight glare in a well-lit room, ambient light causes blacks to look purple, worsening the picture quality. Also, there is the risk of permanent burn-in with constant exposure to the same static elements over time, like if you always have your editing programs on the screen.

Pros
  • Displays deep and inky blacks.
  • Bright and vivid colors.
  • Bright enough to fight glare in most rooms.
  • Fantastic reflection handling.
  • USB hub and KVM switch.
  • Sharp text and image clarity.
Cons
  • Ambient light causes black levels to raise.
  • Risk of burn-in.
  • Needs full calibration for best accuracy.
7.0 Brightness

The ASUS PG32UCDM has decent brightness. It's bright enough to fight glare in most well-lit rooms, but not if you have it opposite a sunny window. It also gets bright enough in HDR to make small highlights pop, but larger highlights are dimmer.

Pros
  • Bright enough to fight glare in most rooms.
  • Small highlights pop in HDR.
Cons
  • Larger highlights are dimmer.
9.9 Response Time

The ASUS PG32UCDM has a near-instantaneous response time, resulting in exceptionally sharp motion.

Pros
  • Near-instantaneous response time.
  • Outstanding refresh rate compliance.
Cons
9.4 HDR Picture

The ASUS PG32UCDM is outstanding for HDR. It displays deep and inky blacks without any blooming around bright objects thanks to its near-infinite contrast ratio and perfect black uniformity. It also displays a wide range of colors and makes them look vivid.

Pros
  • Displays deep and inky blacks.
  • Bright and vivid colors.
Cons
10 SDR Picture

The ASUS PG32UCDM has outstanding SDR picture quality, displaying deep and inky blacks and a wide range of colors.

Pros
  • Displays deep and inky blacks.

Differences Between Sizes And Variants

We tested the 32-inch ASUS PG32UCDM, which is the only size available, and the results are only valid for this model.

Model Size Resolution Panel Type Refresh Rate
PG32UCDM 32" 4k QD-OLED 240Hz

Our unit was manufactured in March 2024; you can see the label here. We tested it with firmware MCM103.

Compared To Other Monitors

The ASUS PG32UCDM is a fantastic monitor for both PC and console gaming thanks to its high 240Hz refresh rate and 4k resolution. Its outstanding picture quality is as good as any display because it offers deep and inky blacks with vivid colors. It even has a ton of useful extra features, like a USB-C port and a KVM switch, making it easy to connect different computers. It's really a step above most of the gaming monitor market, and it's even a good alternative to getting a TV if you want something small. That said, there are other models that use the same QD-OLED panel and offer about the same performance. If you can find the Dell Alienware AW3225QF available in your region for cheaper and you don't mind the curved screen, its lower input lag makes it a better choice for console gaming.

Also see our recommendations for the best OLED monitors, the best gaming monitors, and the best HDR gaming monitors.

Dell Alienware AW3225QF

The Dell Alienware AW3225QF and the ASUS ROG Swift OLED PG32UCDM are similar 4k, 240Hz QD-OLEDs that use the same panel. The Dell has a curved screen, while the ASUS is flat, so you may find the ASUS a better choice if you don't like curved displays. Other than that, the Dell is the better choice for console gaming as it has lower input lag at 120Hz and 60Hz. However, the ASUS is better for productivity, especially in a bright room, as it gets brighter, and it has a few more perks, like a KVM switch.

MSI MPG 271QRX QD-OLED

The MSI MPG 271QRX QD-OLED and the ASUS ROG Swift OLED PG32UCDM are both QD-OLED monitors with a few differences. The ASUS is the better choice for console gaming as it has a higher resolution for more detailed images, and while both monitors have HDMI 2.1 bandwidth, the ASUS can at least take full advantage of the Xbox Series X|S and PS5. On the other hand, the higher 360Hz refresh rate on the MSI is better for competitive PC gaming.

ASUS ROG Swift OLED PG27AQDM

The ASUS ROG Swift OLED PG32UCDM and the ASUS ROG Swift OLED PG27AQDM are different types of OLED displays. The PG32UCDM has a QD-OLED panel, resulting in brighter and more vivid colors, while the PG27AQDM has a W-OLED panel that can display perfect blacks even in bright rooms. Overall, the PG32UCDM is the better choice for most gamers, especially if you want something for console gaming, as it has a higher 4k resolution for more detailed images, and it can take full advantage of the PS5 and Xbox Series X|S, but the lower input lag on the PG27AQDM results in a more responsive feel.

The ASUS PG32UCDM has a sleek design with a gamer-oriented look. It's mainly gray and silver, with some black accents throughout. It has various RGB lighting zones, including on the back and below the stand. The stand has pins that attach to the monitor to transfer power for the lighting, and you can detach the cover at the bottom of the stand. You can also see the bottom of the stand without the cover here.

The ASUS PG32UCDM has a near-infinite contrast ratio, as its QD-OLED panel can turn individual pixels on and off. This means it displays deep blacks next to bright highlights in dark rooms. That said, like any QD-OLED, ambient light causes blacks to look purple, so it doesn't display the same deep blacks in bright rooms.

The ASUS PG32UCDM doesn't have a backlight, so it doesn't require a local dimming feature. However, with a near-infinite contrast ratio, there isn't any blooming around bright objects, and it's the equivalent of a perfect local dimming feature. We still film these videos on the monitor so you can see how the screen performs and compare it with a monitor that has local dimming.

The SDR brightness is good. It gets bright enough to fight glare in most well-lit rooms as long as you have Uniform Brightness disabled, which is what these results represent and are from after calibration in the 'User Mode' GameVisual mode. That said, its brightness isn't the most consistent across different content with it off, so if that bothers you and you don't mind a dimmer image, it's better to enable Uniform Brightness.

The HDR brightness is okay. It gets bright enough to make really small highlights pop, but it can't sustain this brightness with larger highlights, so they don't stand out as much. It follows the PQ EOTF curve well until there's a gradual roll-off before a sharp cut-off at the peak brightness, so it lets highlights get the brightest they can.

These results are with the following settings:

  • HDR Setting: Console HDR
  • Brightness Adjustable: On
  • Auto Logo Brightness: Off
  • Brightness: Max

The Uniform Brightness is locked in HDR and you can't change it. 'Console HDR' is the setting with the most accurate PQ EOTF tracking while also reaching over 1,000 cd/m² of brightness. You can also see the results in the 'Gaming HDR' and 'DisplayHDR 400 True Black' modes below:

The accuracy before calibration in the 'sRGB Cal Mode' picture mode is good. It clamps colors to the sRGB color space well, and although it undersaturates most colors, it isn't noticeable. The color temperature is also almost spot-on with the 6500K target. However, the white balance is off as there's too much red and blue in all shades, and gamma is brighter than the target. Using the sRGB mode locks you out of a few settings, including Uniform Brightness, and you need to use another mode with more oversaturated colors if you want access to those settings.

The ASUS ROG Swift PG32UCDM has excellent text clarity. Thanks to its high pixel density, text looks very sharp, and enabling Windows ClearType (top photo) improves the boldness of letters. While programs don't render text well with its triangular subpixel layout and it isn't as good as other 4k monitors, it's still good enough to use. These photos are in Windows 10, and you can also see them in Windows 11 with ClearType on and with ClearType off.

Due to the triangular subpixel layout, there's still some color fringing around letters and at the edge of windows. It's hard to see unless you look closely at the monitor. Although we didn't experience any eye strain during testing, even with long periods of use, this is something that changes from person to person, and it depends on how sensitive you are to this subpixel layout.

The reflection handling is fantastic. It does an amazing job at reducing glare even from bright light sources, but the biggest downside is that ambient light causes the black levels to raise, so blacks look purple. You can see an example of that here. This is typical of QD-OLEDs, and it's nothing out of the ordinary.

The CAD at 60Hz is outstanding. Pixels transition colors almost perfectly, and any noticeable blur is persistence.

The ASUS PG32UCDM has noticeable VRR flicker with changing frame rates. Although it isn't as bad as other OLEDs, it's still there and can be distracting if the frame rate changes a lot, especially in dark scenes. That said, this doesn't happen if your PC can maintain consistent frame rates.

The backlight isn't technically flicker-free because it has a slight dip in brightness that corresponds to the 240Hz refresh rate. However, it isn't considered pulse-width modulation like on LED-backlit monitors because it isn't a full-screen on-and-off flicker, and you won't notice it.

The ASUS PG32UCDM has low input lag, especially at its max refresh rate. While its input lag is a bit higher than other monitors with 120Hz and 60Hz sources, it's still low enough for a responsive feel.

This monitor has no issues with the Xbox Series X|S and PS5, but you need to enable the console's HDMI override setting for 1440p @ 60Hz to work, which disables VRR. Keep in mind that the Xbox doesn't support HDR with 1440p or 1080p signals, so this isn't a limitation of the monitor.

The ASUS ROG Swift PG32UCDM doesn't have any compatibility issues with macOS. With HDMI 2.1 MacBooks, or over USB-C, windows move to the monitor's screen when you close the lid, and they return to their original position when you reopen it again. However, you can't continue working on the screen with the lid closed on HDMI 2.0 MacBooks, and windows don't return to their original position when reopening the lid.

The ASUS PG32UCDM has a bunch of features, including a KVM switch. This allows you to use the same keyboard and mouse with two different sources, and it works well as it automatically switches when you change inputs. It has other extra perks, some of which you can read about below:

  • Aspect Ratio Control: You can use this setting to change the aspect ratio, including decreasing the image size to simulate a 24.5 or 27-inch screen size.
  • Dolby Vision: ASUS advertises that the monitor will receive Dolby Vision support with a future firmware update. We'll retest the monitor if and when an update becomes available.
  • Dynamic Shadow Boost: Adjusts gamma so that you can see opponents better in dark scenes.
  • GamePlus: Includes different gaming features like an FPS counter, crosshairs, sniper mode, stopwatch, and timer.
  • Lighting Effect: Controls the RGB lighting on the back of the monitor and on the stand. You can also download Armoury Crate to control this.
  • Low Blue Light Filter: Removes blue light to help reduce eye strain.
  • Proximity Sensor: Lowers the brightness if it detects you are away from the monitor over a period of time.

Like most OLED displays, there are also a few settings to help reduce the risk of burn-in, which you can find in the Screen Protection section of the OSD. ASUS also offers a three-year warranty, including against burn-in, although that may vary between regions.

  • Adjust Logo Brightness: Dims static logos that are on the screen, like if you're watching TV.
  • Pixel Cleaning: This feature fixes any burn-in issues that may occur. It happens after you turn off the screen and takes about six minutes to finish. There's also a setting to remind you to turn off the monitor so it can perform the cycle.
  • Screen Move: Moves the image by a few pixels to one side to help reduce the risk of burn-in.
  • Screen Saver: Automatically dims the screen when there's inactivity.
