LG UltraGear 27G810A-B: 27G810A-B, a 27-inch 4K IPS gaming monitor (black). 4K 240 Hz Dual Mode models and the 32GR93U are separate products.

ASUS ROG Swift OLED PG27AQDP: PG27AQDP · 26.5-inch WOLED, 2560 × 1440, 480 Hz; single model

SpecificationLG UltraGear 27G810A-BASUS ROG Swift OLED PG27AQDP
Release year20262024
Panel27-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; anti-glare surface

WOLED uses a white OLED layer with colour filters; each pixel makes its own light, so blacks switch fully off.

ASUS
Pixel densityPixel pitch 0.1554 mm (about 163 ppi)

A small pixel pitch makes text sharper; 4K at 27 inches makes interface elements smaller.

LG		—
Refresh rate180 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		Up to 480 Hz

480 Hz improves motion clarity in fast games; reaching it also needs the graphics card to render close to 480 frames.

ASUS
Response time1 ms GtG (at the Faster setting)

LG gives this figure for the fastest response time setting; it gives no figure for other settings.

LG		0.03 ms (GtG)

GtG is the grey-to-grey pixel transition time, not total input lag.

ASUS
Brightness and contrastTypical 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 1,300 cd/m²; contrast 1,500,000:1 (typical)

The peak figure applies to a small part of the screen; ASUS notes that peak brightness may vary with colour pre-calibration.

ASUS
HDRHDR10; VESA DisplayHDR 400

DisplayHDR 400 is VESA’s lowest HDR certification tier; HDR content plays but bright highlights stay limited.

LG		—
ColourDCI-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		99% DCI-P3, 135% sRGB; 10-bit; ΔE < 2

A colour pre-calibration report is included in the box.

ASUS
SyncNVIDIA 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 inputs2 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		1 × DisplayPort 1.4 (DSC), 2 × HDMI 2.1 (FRL)

DSC compresses the signal in a way considered visually lossless so that 1440p 480 Hz fits within DisplayPort 1.4 bandwidth.

ASUS
USB1 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		—
AudioHeadphone out; DTS Headphone:X; no built-in speakers listed

Headphones or external speakers are needed for sound.

LG		—
StandHeight, tilt, swivel and pivot adjustment; VESA 100 × 100

Pivot lets the screen be used in portrait; VESA 100 × 100 fits standard monitor arms.

LG		Tilt +20°/−5°, swivel ±30°, pivot ±90°, height 0–110 mm; 100 × 100 VESA; 1/4-inch tripod socket ASUS
PowerExternal 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		—
Size and weightWith 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, 6.2 kg; without stand 60.5 × 35.1 × 5.0 cm, 3.5 kg

ASUS states the dimensions are estimates and may vary by region.

HDR and certifications—HDR10; VESA DisplayHDR 400 True Black ASUS
Variable refresh—VESA AdaptiveSync Display 480Hz; AMD FreeSync Premium; G-SYNC Compatible

Variable refresh matches the monitor’s rate to the graphics card’s frame rate to prevent tearing.

ASUS
Other connections—2 × USB 3.2 Gen 1 Type-A hub, headphone jack; no speakers ASUS
Power consumption—Under 27 W in use; under 0.5 W standby, 0.3 W off ASUS
Warranty—3 years, including OLED burn-in

Burn-in is when long-static images leave a mark on an OLED panel; the OLED Care features aim to reduce it.
