ASUS ROG Swift OLED PG32UCWM / LG UltraGear OLED 45GR95QE-B

480 Hz is not available at 4K.

A pixel transition, not total input latency.

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.

Peak brightness is not sustained full-screen brightness.

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.

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.

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

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.

Box contents can vary by country.
