MSI MAG 271QPX QD-OLED E2 / LG UltraGear 27GR93U-B

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.

LG UltraGear 27GR93U-B: 27GR93U-B, the 27-inch 4K 144 Hz IPS model; the spec table is from LG UK, dimensions and weights from LG Canada. The 32-inch 32GR93U and the OLED UltraGear models are separate products.

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
27-inch (68.5 cm) IPS, 3840 × 2160, 16:9; anti-glare surface

At 27 inches, 4K means high pixel density; text and detail look very sharp, though Windows usually needs scaling. IPS panels offer wide viewing angles and good colour, but blacks are not as deep as OLED.

LG
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.

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
DCI-P3 95% typical (90% minimum, CIE1976); 10-bit (8-bit + FRC), 1.07 billion colours; hardware calibration ready

8-bit + FRC imitates 10-bit gradations with rapid dithering; usually invisible to the eye. Hardware calibration writes settings to the monitor’s own memory.

LG
Contrast and viewing angle1,500,000:1 (typical); 178° / 178° MSI1000:1 typical (700:1 minimum); 178° / 178°

1000:1 is ordinary for IPS: blacks can look grey in a dark room. No local dimming is listed.

LG
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.

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.

Stand and mountingTilt -5°/20°, swivel ±30°, height 0–110 mm, pivot ±90°; VESA 100 × 100 mm MSIHeight, tilt, pivot; detachable base; cable holder and mouse cable holder

Per LG Canada dimensions, height with stand ranges from 467.7 to 577.7 mm, so about 110 mm of height adjustment. Pivot turns the screen to portrait; swivel is not listed.

Warranty3 years including OLED burn-in

Terms may vary by country.

Refresh rate and response time—144 Hz; 1 ms (GtG, Faster mode)

LG notes that 1 ms is only achieved with Game Adjust → Response Time → Faster. 144 Hz requires a graphics card with DisplayPort 1.4 (DSC) or HDMI 2.1.

LG
HDR—HDR10; VESA DisplayHDR 400; HDR Effect

DisplayHDR 400 is the entry tier of HDR certification; without local dimming, the bright-to-dark range of HDR content stays limited. HDR Effect is a picture mode that makes SDR content look more HDR-like.

LG
Adaptive sync—NVIDIA G-SYNC Compatible; AMD FreeSync Premium; VRR up to 144 Hz

Matches the monitor’s refresh to the game’s frame rate, reducing tearing and stutter. According to LG, VRR needs a graphics card with DisplayPort 1.4 (DSC) or HDMI 2.1.

LG
Connections—2 × HDMI (2.1), 1 × DisplayPort 1.4 (DSC); USB 3.0 upstream 1, downstream 2; 4-pole headphone out (audio + mic), DTS Headphone:X

DSC (Display Stream Compression) compresses the 4K 144 Hz signal, which exceeds DisplayPort 1.4 bandwidth, with no visible loss. There is no USB-C input and no built-in speakers are listed.

LG
Gaming features—Black Stabilizer, Dynamic Action Sync, Crosshair, FPS Counter, User Defined Key; Hexagon RGB LED lighting

Black Stabilizer brightens dark areas so opponents in shadow are visible; Crosshair places a fixed aiming point at screen centre. Crosshair is unavailable while FPS Counter is on.

LG
Power—External adapter, 19 V / 3.42 A (65 W); 50 W typical, 55 W max; under 0.5 W in sleep LG
