27-inch OLED · UK specification · Samsung part LS27FG502SUXXU
A 27-inch OLED monitor with a 2560 × 1440 panel and a listed 180 Hz native-resolution mode. Its specified depth with stand is 234.5 mm.

Specifications checked 10 Sept 2026Manufacturer specifications, not a hands-on test.
The 2560 × 1440 panel supports a listed 180 Hz native-resolution mode. Check the input-specific conditions alongside the figures.
The listed 100 x 100 VESA pattern gives a mounting option when the mount also meets the monitor’s weight and screw requirements.
The connection changes the refresh ceiling: DisplayPort Max 180Hz / HDMI Max 144Hz. A faster DisplayPort mode does not mean HDMI reaches the same rate.
Allow for the 234.5 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.
The inspected table does not verify height adjustment. Confirm the stand’s adjustment range if fixed screen height would be a problem.

Manufacturer screen-size class, which can be rounded compared with the active panel diagonal.
SourceManufacturer resolution notation: QHD (2,560 x 1,440). See the separate refresh-mode conditions for any lower-resolution configurations.
SourceManufacturer panel designation; technology alone does not establish tested image quality.
SourceManufacturer-listed configuration: DisplayPort Max 180Hz / HDMI Max 144Hz. The comparison uses the native-resolution mode; any higher rate at a lower resolution remains a separate mode. Source, input and cable limits still apply.
SourceManufacturer response-time claim; settings and transition method matter. GtG and MPRT values are different measures and are not independent motion-clarity results.

SourceManufacturer typical brightness. Not an independent measurement; calibration, mode and content affect output.
SourceManufacturer colour specification under its stated colour space and measurement basis. Coverage and gamut volume are not interchangeable, and this is not an independent colour-accuracy measurement.
SourceManufacturer-listed HDR formats or certification. This alone does not establish real-scene HDR quality, local dimming or measured peak brightness.

SourceThe inspected manufacturer interface table explicitly lists no USB-C connection.
SourceManufacturer port counts and versions. Confirm source-device support, cable bandwidth and the exact mode; a connector name alone does not guarantee every advertised configuration.
SourceNo positive charging-output rating is established in the inspected specification.
SourceThe inspected exact-model specification does not establish this feature. It has not been inferred from another model or from an omitted field.
SourceMatch the screw pattern, screw dimensions, product weight and mount load rating; the pattern alone does not verify a safe mount.
SourceManufacturer dimensions in the stated orientation; allow additional room for cables and movement. A listed height range is retained without inferring an adjustment travel.
SourceDepth from the manufacturer dimension tuple. Allow additional room for cable routing and movement.
SourceManufacturer width in the listed landscape configuration.
SourceNet product weight with the supplied stand or arm; packaging excluded.
