UK model 32GX870A-B · black
A 31.5-inch OLED monitor with a 3840 × 2160 panel and a listed 240 Hz native-resolution maximum. The UK specification lists a 249.8 mm depth with the supplied stand.

Specifications checked 17 Oct 2026Manufacturer specifications, not a hands-on test.
LG lists 3840 × 2160 at up to 240 Hz at native resolution. Match the source device, cable and input mode to the stated requirements.
The published with-stand dimensions make it possible to plan desk space without substituting bare-panel measurements.
Refresh, response-time, HDR and colour specifications are manufacturer claims; they do not establish independently measured image quality, input lag or game performance.
Allow room for the listed 249.8 mm stand depth and cable movement. UK documentation does not establish an identical US bundle or a cross-border warranty.

SourceComplete non-placeholder exact-model feature inventory. NO is explicit; placeholder omissions do not establish absence. Per-feature operating restrictions still apply; these are not independent performance results.
SourceLG expressly names this implementation on this exact model page; the named technology does not establish independently measured image quality.
SourceManufacturer-listed native-resolution maximum. Actual modes depend on input, cable, source hardware and configuration. UHD 3840 × 2160 is 240 Hz; separate FHD 1920 × 1080 Dual-Mode is 480 Hz.480 Hz is not the native 4K rate.
SourceManufacturer response-time claim; retain the stated GtG/mode qualification. This is not measured latency, input lag or a cross-model motion result.
SourceExplicit positive in the exact-model table; source implementation/port details remain separately listed.
SourceRetain exact named implementation/certification and model scope; not a generic performance equivalence.

SourceSeparate source-labelled modes. Lower-resolution 480 Hz cannot become native 4K refresh or a measured game-performance advantage.
SourceThe same page separately advertises 0.03 ms and has a Faster Mode footnote naming 1 ms. Both source statements are retained; no unqualified real-world response or presumed equivalence of settings is asserted.
SourceExplicit manufacturer typical brightness. Peak HDR brightness/window sizes, where stated, are separate claims; not an independent measurement.

SourceRetain exact colour space, percentage and CIE basis. Gamut coverage/volume is not an independent colour-accuracy result.

SourcePublished application availability is separate from hardware calibration support or a measured calibration result.
SourceExplicit positive in the exact-model table; source implementation/port details remain separately listed.
SourceExact UK manufacturer connection inventory. NO is an explicit source negative; omitted or dash entries remain unresolved. Connector shape does not prove an unlisted generation, data mode, bandwidth or charging protocol.
SourceExact-model source does not establish this capability; dash or omission remains unknown, not a negative. · Exact-model source does not establish this capability; dash or omission remains unknown, not a negative.
SourcePositive downstream USB inventory; computer data requires its actual upstream connection. Connector generation and ports remain as separately sourced in the connection inventory.
SourceStated monitor output to a compatible connected device, not monitor input power or an unconditional charging speed.
SourceThe exact model explicitly lists Height in its stand movement inventory. Exact travel/angle is separate; unlisted movements are not asserted absent.
SourceManufacturer claim under its labelled measurement basis; retain raw precision and qualifications.
SourceThe exact model explicitly lists Swivel in its stand movement inventory. Exact travel/angle is separate; unlisted movements are not asserted absent.
SourceThe exact model explicitly lists Pivot in its stand movement inventory. Exact travel/angle is separate; unlisted movements are not asserted absent.
SourceManufacturer tuple and any raised/lowered positions are retained; leave cable clearance and movement room. No axis or travel is invented.
SourceExplicit W axis of the manufacturer with-stand tuple.
SourceExplicit D axis of the manufacturer with-stand tuple; allow separate cable clearance.
