ASUS ROG Swift PG27AQDM-R 27-inch OLED Monitor: features and specs

The ASUS ROG Swift PG27AQDM-R is a 27-inch class OLED gaming monitor with a 2560 x 1440 (QHD) resolution and a 240Hz refresh rate. The panel measures 26.5 inches viewable. It is built for fast competitive games and for colour-rich content, and the listing says a monitor arm is included.

Why OLED matters

On an OLED panel, each pixel makes its own light. A pixel that is switched off is black, rather than a lit backlight with a filter in front of it. That is why ASUS talks about the darkest black hues, and why OLEDs typically show strong contrast in dark scenes. They also tend to respond very quickly, which suits games.

240Hz and 0.03ms

Refresh rate is how many times per second the image updates. At 240Hz, motion looks smoother than on a 60Hz or 144Hz screen, provided your graphics card can produce enough frames. ASUS lists a 0.03ms gray-to-gray response time, a measure of how fast a pixel changes between shades. G-Sync compatible technology helps the monitor and a compatible graphics card stay in step, which prevents screen tearing. 1440p is a popular balance, as it is sharper than 1080p but easier to drive at high frame rates than 4K.

Colour and brightness

ASUS lists 99% DCI-P3 coverage, a wide gamut used in cinema and many HDR videos, and true 10-bit colour, which allows smoother gradients. A colour difference of Delta E below 2 is the figure ASUS gives for accuracy, and values under 2 are usually hard to see by eye. Peak brightness is 1000 nits, but only in a small area: ASUS specifies 3% of the screen with HDR on. OLED brightness typically falls as more of the screen is lit, so large bright scenes will appear dimmer than that.

Burn-in measures

OLED screens can suffer from burn-in if static images stay on screen for long periods. ASUS says a large custom heatsink and intelligent voltage optimization manage heat and reduce the risk of burn-in. It does not claim to eliminate it. An optional uniform brightness setting keeps luminance consistent. Varying content and following the manual's care advice are the usual precautions.

Coating and design

The anti-glare micro-texture coating reduces reflections, which ASUS says supports accurate colours. A matte finish can lift blacks slightly in bright rooms, compared with a glossy panel. The listing gives packaged dimensions of roughly 23.8 x 25.8 x 26.3 inches and a weight of 22.1 lb (10 kg). ASUS includes a 3-year warranty.

Who it suits

It suits players who want a fast, high-contrast 1440p screen, and creators who like OLED contrast and wide colour. It needs a graphics card able to drive high frame rates to use the 240Hz.

What to check before you buy

• Graphics card: confirm that it can reach high frame rates at 1440p.
• Ports: check the monitor's connections against your computer, and that your cable supports 240Hz.
• Room light: consider the lighting where you will use it, as OLED can look different in a bright room.
• Static content: think about long periods of fixed images, such as toolbars.
• Desk space: check the arm clamp or mount requirements in the manual.
