MSI MAG 271QPX QD-OLED E2 / MSI MPG 491CQP QD-OLED

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.

MSI MPG 491CQP QD-OLED: MPG 491CQP QD-OLED, 49-inch 32:9 curved monitor. The Samsung Odyssey OLED G9 of the same size and MSI’s other 49-inch models are separate.

Panel26.5-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		49-inch QD-OLED; 5120 × 1440 (DQHD), 32:9; 1800R curve

The 32:9 ratio gives a workspace equivalent to two 27-inch 1440p monitors side by side. The 1800R curve keeps the edges closer to the eyes.

MSI
Refresh rate240 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		—
Response time0.03 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 HDRSDR 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		—
Colour10-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		99% DCI-P3, 146% sRGB, 98% Adobe RGB; 10-bit (1.07 billion colours) MSI
Contrast and viewing angle1,500,000:1 (typical); 178° / 178° MSI—
Inputs2 × 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		—
PiP / PbPPicture-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.

OLED care and coolingMSI 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.

Terms may vary by country.

MSI		3 years, including panel burn-in

Static images left on an OLED panel for long periods can leave permanent marks; MSI covers this risk under warranty.

In the boxDisplayPort cable, HDMI cable, power cord, quick guide MSI—
Refresh and response—144 Hz (adaptive range 48–144 Hz); 0.03 ms (GtG)

Adaptive sync prevents tearing while the frame rate stays between 48 and 144. Reaching 144 fps at full resolution needs a very powerful graphics card.

MSI
Brightness and contrast—Typical SDR 250 nits; 1,500,000:1; DisplayHDR True Black 400

True Black 400 is the OLED-class certification for very low black level and 400-nit HDR brightness.

MSI
Adaptive sync—AMD FreeSync Premium Pro

The Premium Pro tier includes low frame rate compensation and low-latency tone mapping in HDR.

MSI
Connections—1 × DisplayPort 1.4a; 2 × HDMI 2.1; 1 × USB-C (DP Alt Mode, 90 W PD); 2 × USB 2.0 Type-A; 1 × USB 2.0 Type-B; headphone out

USB-C takes video from a laptop over one cable and charges it at up to 90 W. The USB ports run at USB 2.0 speed; there are no built-in speakers.

MSI
Multi-view—PiP / PbP

PbP splits the 49-inch screen side by side between two sources to show two computers at once; PiP shows one source in a small window over the other.
