Panel26.5-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		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 and response240 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 syncG-SYNC Compatible; AMD FreeSync Premium Pro

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

MSI		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
Brightness and HDRSDR 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 contrastDCI-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		—
Video inputs1 × 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		—
USB and audio2 × USB-A 5 Gbit/s; 1 × USB-B 5 Gbit/s (upstream); headphone out; no built-in speakers MSI—
KVM and multi-viewKVM; 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 mountingTilt -5°/20°; swivel ±30°; pivot ±90°; height 0–110 mm; 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.

LG
PowerInternal power board; 100–240 V, 50/60 Hz

No external power brick is needed.

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

Coverage and duration may vary by country.

MSI		—
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
Contrast and viewing angle—1000:1 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
Colour—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
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
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.
