ASUS ROG Swift OLED PG27AQDP / LG UltraGear OLED 45GR95QE-B

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

800R means the screen curves like part of a circle with an 800 mm radius, wrapping the edges around your view. At 45 inches, 1440p gives low pixel density: up close, text and fine detail look less sharp than on a 27-inch 1440p screen.

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

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

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

LG’s typical brightness refers to a full-screen SDR image; with self-emissive OLED pixels black switches fully off, giving very high contrast.

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

Hardware calibration writes settings into the monitor itself through LG Calibration Studio, so the colour setup stays with the monitor even if the computer changes.

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

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

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

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

Box contents can vary by country.

240 Hz shows very smooth motion when a game approaches 240 frames per second, which needs a powerful graphics card. 0.03 ms grey-to-grey describes the fast transition of OLED pixels; it is not total input lag.

G-SYNC Compatible and FreeSync Premium match the refresh rate to the graphics card’s frame rate to reduce tearing and stutter. HDR effect is a picture mode that adds HDR-like contrast to SDR content in software; it is not real HDR.

Black Stabilizer brightens detail in dark scenes; Dynamic Action Sync is a mode that reduces input lag.

PiP shows a second input in a small window over the main picture, for example a PC and a console at the same time. LG does not list PbP (side-by-side split) for this model.

DSC (Display Stream Compression) compresses high-bandwidth signals such as 3440 × 1440 at 240 Hz over DisplayPort 1.4 without visible loss. With the USB upstream connected, the monitor’s USB-A ports act as a hub for the computer. A headset with a mic plugs into the 4-pole jack; DTS Headphone:X adds virtual surround. No built-in speakers are listed.
