Specification	LG UltraGear 27G810A-B	ASUS ROG Swift OLED PG32UCDM
Release year	2026	2024
Panel	27-inch IPS; 3840 × 2160; 16:9 IPS panels offer wide viewing angles and consistent colour; black level stays behind OLED and VA panels. LG	31.5-inch QD-OLED; 3840 × 2160 (16:9); 240 Hz; 0.03 ms (GtG); 10-bit; 0.182 mm pixel pitch; anti-reflection surface In QD-OLED, blue OLED light is converted to red and green by quantum dots, keeping colours saturated. The semi-glossy surface can make blacks look grey in a bright room. ASUS
Pixel density	Pixel pitch 0.1554 mm (about 163 ppi) A small pixel pitch makes text sharper; 4K at 27 inches makes interface elements smaller. LG	—
Refresh rate	180 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 time	1 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 contrast	Typical 400 cd/m² (minimum 320); contrast 1000:1 1000:1 contrast is typical for IPS; blacks can look grey in a dark room. LG	HDR peak 1000 cd/m²; contrast 1,500,000:1 1000 cd/m² is a peak reached on a small part of the screen; full-screen white is much dimmer. ASUS notes the value can vary due to pre-calibration. ASUS
HDR	HDR10; VESA DisplayHDR 400 DisplayHDR 400 is VESA’s lowest HDR certification tier; HDR content plays but bright highlights stay limited. LG	—
Colour	DCI-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	—
Sync	NVIDIA 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	Adaptive-Sync; FreeSync Premium Pro; G-SYNC Compatible; ELMB ELMB is a mode that inserts black between frames to reduce motion blur. ASUS
Video inputs	2 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	—
USB	1 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	—
