Release year	2023	2021
Panel	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	27-inch (68.5 cm) IPS; 1920 × 1080; 16:9; pixel pitch 0.3108 mm A 0.31 mm pixel pitch works out to about 82 ppi at 27 inches. Viewing angles are 178°/178°. LG
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	—
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	—
