LG UltraGear 27G810A-B: 27G810A-B, a 27-inch 4K IPS gaming monitor (black). 4K 240 Hz Dual Mode models and the 32GR93U are separate products.

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.

Release year20262024
Panel27-inch IPS; 3840 × 2160; 16:9

IPS panels offer wide viewing angles and consistent colour; black level stays behind OLED and VA panels.

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
Pixel densityPixel pitch 0.1554 mm (about 163 ppi)

A small pixel pitch makes text sharper; 4K at 27 inches makes interface elements smaller.

LG		—
Refresh rate180 Hz at 4K; 360 Hz at Full HD with Dual Mode

Dual Mode lowers the resolution to Full HD to allow a higher refresh rate; the image is less sharp in that mode.

LG		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 time1 ms GtG (at the Faster setting)

LG gives this figure for the fastest response time setting; it gives no figure for other settings.

LG		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 contrastTypical 400 cd/m² (minimum 320); contrast 1000:1

1000:1 contrast is typical for IPS; blacks can look grey in a dark room.

LG		—
HDRHDR10; VESA DisplayHDR 400

DisplayHDR 400 is VESA’s lowest HDR certification tier; HDR content plays but bright highlights stay limited.

LG		—
ColourDCI-P3 95% (typical, CIE1976); 1.07 billion colours; factory calibration

DCI-P3 coverage describes how much of the wide colour space used in films and games can be shown.

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
SyncNVIDIA G-Sync Compatible, AMD FreeSync, VESA Adaptive-Sync

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

LG		—
Video inputs2 HDMI 2.1, 1 DisplayPort 1.4 (DSC)

DSC uses visually lossless compression to fit a 4K 180 Hz signal into DisplayPort 1.4 bandwidth.

LG		—
USB1 USB 3.0 upstream, 2 USB 3.0 downstream; no USB-C

The USB ports act as a hub; no USB-C connection for video or charging is listed.

LG		—
AudioHeadphone out; DTS Headphone:X; no built-in speakers listed

Headphones or external speakers are needed for sound.

LG		—
StandHeight, tilt, swivel and pivot adjustment; VESA 100 × 100

Pivot lets the screen be used in portrait; VESA 100 × 100 fits standard monitor arms.

LG		—
PowerExternal adapter; 100–240 V; under 0.5 W in sleep

The external adapter keeps the monitor thinner but takes extra space on the desk.

LG		—
Size and weightWith stand 24.2 × 21.0 × 8.7 in (raised), 16.3 lb (about 7.4 kg); without stand 24.2 × 14.6 × 2.0 in, 10.8 lb (about 4.9 kg)

Use the weight without the stand when choosing a monitor arm.

LG		609 × 242 × 416 mm with stand; 609 × 72 × 362 mm without; 5.3 kg without stand MSI
In the boxDisplayPort and HDMI cables

No USB upstream cable is listed.

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
Stand and mounting—Tilt -5°/20°, swivel ±30°, height 0–110 mm, pivot ±90°; VESA 100 × 100 mm MSI
Warranty—3 years including OLED burn-in

Terms may vary by country.
