Specification	LG UltraGear 27G810A-B	ASUS ROG Swift OLED PG27AQDM
Release year	2026	2023
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	26.5-inch WOLED; 2560 × 1440 (16:9); 0.229 mm pixel pitch; anti-glare surface WOLED is LG Display’s panel type using a white OLED layer with colour filters; each pixel makes its own light, so blacks go fully dark. Long-lasting static images raise the risk of burn-in. 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 1,000 cd/m²; contrast 1,500,000:1; 10-bit (1.07 billion colours) Peak brightness applies to a small part of the screen; with a full white screen brightness drops noticeably. ASUS notes peak brightness may vary with colour 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	HDR10 Dolby Vision and HDR10+ support are not listed. ASUS
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	DCI-P3 99%; sRGB 135%; factory pre-calibration report ASUS
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	—
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	—
Audio	Headphone out; DTS Headphone:X; no built-in speakers listed Headphones or external speakers are needed for sound. LG	—
Stand	Height, tilt, swivel and pivot adjustment; VESA 100 × 100 Pivot lets the screen be used in portrait; VESA 100 × 100 fits standard monitor arms. LG	—
Power	External 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	External power adapter; 100–240 V, 50/60 Hz ASUS
Size and weight	With 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 60.5 × 54.8 × 27.4 cm, 6.9 kg; without stand 60.5 × 35.1 × 5.0 cm, 4.2 kg ASUS
In the box	DisplayPort and HDMI cables No USB upstream cable is listed. LG	—
Refresh rate and response	—	240 Hz (DisplayPort); 120 Hz over HDMI; 0.03 ms (GtG) 240 Hz is only available through the DisplayPort input; ASUS’s signal table limits the HDMI inputs to 120 Hz. For PC games above 120 Hz, use a DisplayPort cable. ASUS
Variable refresh	—	VESA AdaptiveSync Display 240Hz; AMD FreeSync Premium; G-SYNC Compatible Variable refresh matches the monitor to the graphics card’s frame rate to reduce tearing and stutter. ASUS
Inputs	—	1 × DisplayPort 1.4 DSC; 2 × HDMI 2.0; headphone jack; 2 × USB 3.2 Gen 1 Type-A hub DSC (Display Stream Compression) compresses the signal without visible loss so DisplayPort 1.4 has enough bandwidth for high refresh rates. There are no speakers and no USB-C input. ASUS
OLED care and warranty	—	ASUS OLED Care; 2-year warranty (including panel burn-in) The warranty also covers panel burn-in; terms may vary by region. ASUS
Stand and mounting	—	Tilt +20° / −5°; swivel ±30°; pivot ±90°; 0–110 mm height; 1/4-inch tripod socket; VESA 100 × 100 (with kit); Aura RGB The VESA mount kit is included in the box. ASUS
