ASUS ROG Swift OLED PG27UCDM / MSI MAG 271QPX QD-OLED E2

ASUS ROG Swift OLED PG27UCDM: PG27UCDM; a single 26.5-inch 4K 240 Hz model. The larger PG32UCDM is a separate monitor.

MSI MAG 271QPX QD-OLED E2: 26.5-inch flat MAG 271QPX QD-OLED E2, black (9S6-3CD89T). The original 360 Hz MAG 271QPX QD-OLED and the MPG 271QRX are different models.

Panel26.5-inch QD-OLED, 16:9; 3840 × 2160 (4K); 0.153 mm pixel pitch

The small pixel pitch (about 166 ppi) makes text and interface edges look sharper than on 27-inch 1440p monitors.

ASUS		26.5-inch flat QD-OLED; 2560 × 1440 (WQHD), 16:9; anti-reflection surface

In QD-OLED, light from a blue OLED layer is converted to red and green by quantum dots; because each pixel emits its own light, blacks turn fully off.

MSI
Refresh rate and VRR240 Hz; 48–240 Hz variable refresh on HDMI and DP/USB-C inputs; FreeSync Premium Pro, G-SYNC Compatible, VESA AdaptiveSync Display 240Hz

All inputs support 240 Hz at 4K; variable refresh prevents tearing and stutter as the game frame rate moves between 48 and 240.

ASUS		—
Response time0.03 ms (GtG)

Grey-to-grey transition time; because OLED pixels change much faster than LCD, motion blur depends mostly on the refresh rate.

ASUS		0.03 ms (GtG)

This is grey-to-grey transition time; OLED’s very fast transitions reduce motion blur, but it is not the same as total input lag.

MSI
Brightness and contrast1,000 cd/m² HDR peak; 1,500,000:1 typical contrast

1,000 cd/m² is a peak reached on a small area of the screen; a full white screen stays much lower. ASUS gives no typical SDR brightness value.

ASUS		—
HDRVESA DisplayHDR 400 True Black; HDR10; Dolby Vision

The True Black tier measures OLED’s very low black level; 400 is the minimum peak brightness threshold in the certification test. Dolby Vision support lets compatible sources use scene-by-scene HDR data.

ASUS		—
Colour99% DCI-P3, 145% sRGB; 10-bit (1.07 billion colours); ΔE < 2

ΔE < 2 means factory calibration deviates from target colours by an amount most people cannot see; a calibration report is included.

ASUS		10-bit (1.07 billion colours); 99.1% DCI-P3 and 100% sRGB coverage (CIE 1976); ΔE ≤ 2

The wide gamut gives saturated colour in HDR and games; MSI states colour accuracy as ΔE ≤ 2.

MSI
Inputs1 × DisplayPort 2.1; 2 × HDMI 2.1 (FRL); 1 × USB-C (DP Alt Mode, 90 W power delivery); headphone jack

USB-C takes video over a single cable and supplies up to 90 W to a laptop. The HDMI 2.1 inputs can be used for 4K 120 Hz on consoles.

ASUS		2 × HDMI 2.1 (HDCP 2.3), 1 × DisplayPort 1.4a, 1 × USB-C (DP Alt, 15 W PD), headphone out

The HDMI 2.1 inputs support WQHD 240 Hz on consoles at 48 Gbps (Console Mode). USB-C with 15 W only charges small devices such as phones and is not enough to charge a laptop; the port runs at USB 2.0 speed and there is no separate USB hub.

MSI
USB and KVM3 × USB-A 5 Gbps (USB 3.2 Gen 1) hub; KVM switch

KVM moves the keyboard and mouse attached to the monitor between two computers when the input is switched.

ASUS		—
SpeakersNone

A headphone jack or external speakers are needed for audio.

OLED protectionASUS OLED Care; Neo Proximity Sensor

OLED Care includes burn-in prevention functions such as pixel cleaning, screen shift, logo brightness adjustment and taskbar detection. The proximity sensor dims the screen when the user leaves, reducing static image time.

MSI
Refresh rate—240 Hz; Adaptive-Sync 48–240 Hz; 2560 × 1440 at 240 Hz over DisplayPort 1.4a, both HDMI 2.1 ports and USB-C (DP Alt)

240 Hz shows 240 frames per second for smooth, clear motion in fast games, provided the graphics card can produce that frame rate. Adaptive-Sync matches the display’s refresh to the card’s frame rate to prevent tearing.

MSI
Brightness and HDR—SDR 250 nits (typical); HDR 450 nits at 10% window and 1000 nits peak at 3% window; VESA DisplayHDR True Black 400

OLED brightness falls as the lit area grows; 1000 nits appears only in very small bright highlights. True Black 400 certifies deep blacks with at least 400 nits HDR performance.

MSI
Contrast and viewing angle—1,500,000:1 (typical); 178° / 178° MSI
PiP / PbP—Picture-in-picture and picture-by-picture support

Shows two sources at once: in PiP one is a small window, in PbP the two sit side by side.

MSI
OLED care and cooling—MSI OLED Care 2.0; fanless design with graphene film and custom heatsink

OLED Care includes protection functions that reduce the risk of static images leaving marks (burn-in). With no fan, it makes no noise while running.
