LG UltraGear OLED 27GS95QE-B / MSI MAG 271QPX QD-OLED E2

LG UltraGear OLED 27GS95QE-B: 27GS95QE-B (Y24), 26.5-inch QHD 240 Hz OLED gaming monitor. The earlier 27GR95QE-B and the 480 Hz 27GX790A-B are separate models.

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 (67.3 cm) OLED; 2560 × 1440; 16:9; 0.2292 mm pixel pitch

Although sold in the 27-inch class, the viewable diagonal is 26.5 inches. OLED lights each pixel itself, so there is no backlight bleed.

LG		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
Speed240 Hz; 0.03 ms (GtG) response time

GtG is the time a pixel takes to change from one grey level to another; lower values reduce motion blur.

LG		—
Brightness and contrast275 nits typical, 250 nits minimum; contrast 1,500,000:1 typical, 1,200,000:1 minimum

LG quotes 275 nits for a full-white screen (100% average picture level); small bright areas can be brighter.

LG		—
ColourDCI-P3 98.5% typical (90% minimum, CIE1976); 1.07 billion colours; factory calibrated; hardware calibration ready

A printed calibration report is included. Hardware calibration uses LG Calibration Studio with a compatible meter.

LG		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
HDR and syncHDR10; VESA DisplayHDR True Black 400; NVIDIA G-SYNC Compatible; AMD FreeSync Premium Pro; VRR

Variable refresh rate matches the monitor to the graphics card’s frame rate, reducing tearing and stutter.

LG		—
ConnectionsHDMI 2.1; 1 × DisplayPort 1.4 (DSC); USB 3.0 (1 upstream, 2 downstream); optical audio out (SPDIF); 4-pole headphone out, DTS Headphone:X

DSC compression helps carry QHD at 240 Hz over DisplayPort 1.4. There is no USB-C video input.

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
Response time—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 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
Inputs—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
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.

MSI
Warranty—3 years including OLED burn-in

Terms may vary by country.

Power consumption—40 kWh/1000 h in on mode; standby 0.5 W; off 0.3 W; energy class G MSI
