LG UltraGear OLED 27GR95QE-B: 27GR95QE-B: a 2023 26.5-inch (27-inch class) 1440p 240 Hz OLED gaming monitor. Its successor 27GS95QE-B and the 4K/1080p dual-mode 27GX790A-B are separate models.

SpecificationASUS ROG Swift OLED PG27AQDPLG UltraGear OLED 27GR95QE-B
Release year20242023
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 (67.32 cm) OLED, 2560 × 1440 (16:9); 0.2292 mm pixel pitch; 1.07 billion colours

Because self-lit OLED pixels can switch fully off, blacks are true black; LG gives typical contrast as 1,500,000:1. 1.07 billion colours corresponds to 10-bit colour depth.

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

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

ASUS		—
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.

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

DSC (Display Stream Compression) uses visually lossless compression to fit a 1440p 240 Hz signal within DisplayPort 1.4 bandwidth. The HDMI 2.1 inputs support VRR on consoles. There is no USB-C video input.

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

ASUS		Without stand 604.4 × 350.6 × 45.3 mm, 5.05 kg; with stand 604.4 × 464.4–574.4 × 258 mm, 7.35 kg LG
Warranty3 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.

Refresh rate and response time—240 Hz; 0.03 ms (GtG)

240 Hz shows 240 frames per second, making motion smoother and less blurred in fast games; this needs a graphics card producing 240 fps and a DisplayPort or HDMI 2.1 connection. GtG is the time a pixel takes to change from one grey level to another.

LG
Brightness—Typical 200 cd/m², minimum 160 cd/m²

These are full-screen SDR figures; small HDR highlights can be brighter. LG does not give a peak HDR figure in the spec table.

LG
Colour and HDR—98.5% DCI-P3 (typical), 90% (minimum); HDR10; factory calibrated; hardware calibration ready

Hardware calibration uses LG Calibration Studio and a compatible colorimeter to adjust the monitor’s own colour tables. No VESA DisplayHDR certification is listed.

LG
Adaptive sync and gaming—NVIDIA G-SYNC Compatible, AMD FreeSync Premium, VRR; Black Stabiliser, Dynamic Action Sync, crosshair, FPS counter

Adaptive sync matches the monitor’s refresh to the graphics card’s frame rate to reduce tearing and stutter. Dynamic Action Sync is meant to reduce input lag.

LG
USB and audio—1 × USB 3.0 upstream, 2 × USB 3.0 downstream; 4-pole headphone output (sound + mic) with DTS Headphone:X; optical digital audio out (S/PDIF)

There are no built-in speakers. DTS Headphone:X gives virtual 3D audio over headphones.

LG
Stand and mounting—Tilt, height, swivel and pivot adjustment; VESA 100 × 100 LG
Lighting and remote—Hexagon Lighting on the back; remote control included LG
Power—External adapter, AC 100–240 V; typical 74 W, maximum 94 W; under 0.5 W in sleep LG
