Release year20262025
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; 3840 × 2160; 10-bit (1.07 billion colours)

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 switch off completely. 4K in the 27-inch class gives very sharp text at about 166 ppi.

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		—
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		—
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		—
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		1 × DisplayPort 2.1a (UHBR20); 2 × HDMI 2.1 (UHD 240 Hz); 1 × USB-C (DP Alt Mode, 98 W PD)

UHBR20 offers 80 Gbit/s, enough to carry 4K 240 Hz 10-bit without compression, provided the GPU also supports DP 2.1 UHBR20. USB-C delivers video, data and up to 98 W laptop charging over one cable.

MSI
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		Internal power board; 100–240 V, 50/60 Hz

No external power brick is needed.

MSI
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		With stand 610 × 242 × 422 mm, without stand 610 × 69 × 356 mm; net 8.1 kg MSI
In the boxDisplayPort and HDMI cables

No USB upstream cable is listed.

LG		—
Refresh and response—240 Hz (adaptive range 48–240 Hz); 0.03 ms GtG

4K 240 Hz is reached over DisplayPort 2.1a or HDMI 2.1. 0.03 ms is pixel transition time, not total input lag.

MSI
Adaptive sync—G-SYNC Compatible; AMD FreeSync Premium Pro

Matching refresh rate to the GPU frame rate reduces tearing and stutter.

MSI
Brightness and HDR—SDR 250 nits; HDR 450 nits at 10% APL, 1000 nits peak at 3% APL; DisplayHDR True Black 400

1000 nits is reached only when a very small part of the screen is bright; OLED brightness drops markedly on a full white screen. True Black 400 is the VESA tier for OLEDs that also measures black level.

MSI
Colour and contrast—DCI-P3 99%, Adobe RGB 98%, sRGB 138% (CIE 1976); 1,500,000:1 typical contrast

138% of sRGB means the panel can oversaturate standard content; use the sRGB mode for accurate colour.

MSI
USB and audio—2 × USB-A 5 Gbit/s; 1 × USB-B 5 Gbit/s (upstream); headphone out; no built-in speakers MSI
KVM and multi-view—KVM; PiP and PbP

KVM shares a keyboard and mouse connected to the monitor between two computers. PiP shows one source in a small window, PbP shows two sources side by side.

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

Coverage and duration may vary by country.
