Panel27-inch QD-OLED · 2560 × 1440 (QHD), 16:9

QD-OLED puts a quantum-dot colour converter over a blue-emitting OLED layer; each pixel produces its own light.

Samsung		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 rateUp to 500 Hz

Samsung notes the maximum may vary by input source; reaching 500 Hz requires a source that can output it.

Samsung		—
Response time0.03 ms (GtG)

GtG is the time a pixel takes to change from one grey level to another; lower values mean less smearing in motion.

Samsung		—
Brightness300 nits (typical)

The typical figure is for full-screen SDR; small bright areas go higher in HDR.

Samsung		—
HDRDisplayHDR True Black 500 · HDR10+ Gaming · 1000 nits typical, 800 nits minimum at 3% window (peak brightness set to High)

A 3% window means only a small part of the screen is lit; brightness drops below this in large bright scenes.

Samsung		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
Colour99% DCI-P3 · 1 billion colours

DCI-P3 is the wide colour space used for cinema and HDR content.

Samsung		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.

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
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
Stand and mounting—Height, 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.
