SpecificationASUS ROG Swift OLED PG27AQDPLG UltraGear OLED 27GS95QE-B
Release year20242024
Panel26.5-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		26.5-inch (67.3 cm) OLED; 2560 × 1440; 16:9; 0.2292 mm pixel pitch

Although sold in the 27-inch class, the viewable diagonal is 26.5 inches. OLED lights each pixel itself, so there is no backlight bleed.

LG
Resolution2560 × 1440, 16:9 ASUS—
Refresh rateUp 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 time0.03 ms (GtG)

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

ASUS		—
Brightness and contrastHDR 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		275 nits typical, 250 nits minimum; contrast 1,500,000:1 typical, 1,200,000:1 minimum

LG quotes 275 nits for a full-white screen (100% average picture level); small bright areas can be brighter.

LG
Colour99% DCI-P3, 135% sRGB; 10-bit; ΔE < 2

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

ASUS		DCI-P3 98.5% typical (90% minimum, CIE1976); 1.07 billion colours; factory calibrated; hardware calibration ready

A printed calibration report is included. Hardware calibration uses LG Calibration Studio with a compatible meter.

HDR and certificationsHDR10; VESA DisplayHDR 400 True Black ASUS—
Variable refreshVESA 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		—
Video inputs1 × 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.

Speed—240 Hz; 0.03 ms (GtG) response time

GtG is the time a pixel takes to change from one grey level to another; lower values reduce motion blur.

LG
HDR and sync—HDR10; VESA DisplayHDR True Black 400; NVIDIA G-SYNC Compatible; AMD FreeSync Premium Pro; VRR

Variable refresh rate matches the monitor to the graphics card’s frame rate, reducing tearing and stutter.

LG
Connections—HDMI 2.1; 1 × DisplayPort 1.4 (DSC); USB 3.0 (1 upstream, 2 downstream); optical audio out (SPDIF); 4-pole headphone out, DTS Headphone:X

DSC compression helps carry QHD at 240 Hz over DisplayPort 1.4. There is no USB-C video input.
