The PG27UCDM fits 4K into a 27-inch-class screen. At normal desk distance that gives fine edges and small type a particular crispness. It also means your graphics card has to render just as many pixels as it would for a much larger 4K monitor.

ASUS ROG Swift OLED PG27UCDM review
Published
Best forPC owners who want 4K detail and 240 Hz motion without moving to a 32-inch desk monitor.
At a glance
- Screen size
- 26.5 inches
- Panel technology
- QD-OLED
- Native resolution
- 3840 × 2160
- Refresh rate
- 240 Hz
Pros
- High pixel density with a 240 Hz ceiling.
- DisplayPort and USB-C accommodate a gaming PC and a compatible laptop.
Cons
- Bright objects opposite the glossy screen can be distracting.
- High frame rates at native 4K take substantial graphics performance.
Display
- 26.5 inches
- 3840 × 2160
- QD-OLED
The extra pixels are useful with a fine map or a crowded game interface. Use desktop scaling to get the text size you want. If the same monitor will face a bright window, plan its position before buying: PCWorld saw distinct reflections of bright objects in its test of the glossy screen. 1
Gaming
- 240 Hz
- Adaptive sync
A 240 Hz refresh interval is roughly four milliseconds. A game running at 80 frames per second still supplies a new frame only every twelve and a half milliseconds. For demanding games, compare native rendering and a good upscaling mode before giving up resolution altogether.
Connectivity & Care
- DisplayPort 2.1a UHBR20
- USB-C with up to 90 W
A suitably equipped desktop can use the high-bandwidth DisplayPort input, while a compatible laptop can connect through USB-C. ASUS also includes a proximity sensor to help protect the OLED when you walk away. Keep the panel-care routines enabled if a fixed toolbar spends much of the day on screen.
Alternatives
The PG27AQWP-W takes almost the opposite route, spending its bandwidth on 540 Hz at 1440p. The PG27UCDM makes more sense for games with intricate scenery or for a desk that also handles detailed photos.
Verdict
Choose the PG27UCDM when you want a compact physical display without sacrificing a 4K workspace. Its value is easier to realize with a fast PC and controllable room lighting.
