24.5-inch Fast IPS · UK specification
A 24.5-inch Fast IPS monitor with a 1920 × 1080 panel and a listed 400 Hz native-resolution mode. Its specified depth with stand is 207.6 mm.

Specifications checked 27 Sept 2026Manufacturer specifications, not a hands-on test.
The 1920 × 1080 panel supports a listed 400 Hz native-resolution mode. Check the input-specific conditions alongside the figures.
The supplied stand has a listed 130 mm height adjustment, allowing its position to change without adding a separate mount.
The advertised 420 Hz setting is an overclock. The listed native configuration is 400 Hz; the higher setting needs the supported configuration and is not guaranteed stock operation.
Allow for the 207.6 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.

56 specifications in 10 groups. Values are manufacturer specifications unless a row says “Measured result” or “Calculated from cited specifications”. 1 row repeats a listed fact in the manufacturer’s own wording, kept under “Manufacturer wording”.
Manufacturer-listed panel diagonal; a rounded size may appear in the product name.
SourceManufacturer resolution notation: 1920x1080. See the separate refresh-mode conditions for any lower-resolution configurations.
SourceManufacturer panel designation; technology alone does not establish tested image quality.
SourceAt the native panel resolution. Manufacturer lists 420Hz (OC, 400Hz native). The overclocked setting is listed separately and is not a guaranteed stock mode. Available modes depend on input, cable and source. Listed vertical input range: HDMI:48~240Hz; DP:48~400Hz; DP OC:48~420Hz(H).
SourceAOC's UK specification lists 'Response time GtG 1 ms' (and its Fast IPS text says up to 1ms GtG), while the same page's feature section is headed '0.5ms Response time GTG'. The page contradicts itself, so the claim is left unresolved.

SourceManufacturer response-time claim; settings and transition method matter. GtG and MPRT values are different measures and are not independent motion-clarity results.
SourceNeeds a compatible source, input and driver.
SourceAOC's UK page lists 350 cd/m² under 'Brightness in nits' without stating whether it is typical, sustained or peak output or giving a window size; the figure is kept as brightness_claim.
SourceAOC does not state the window size or whether this is sustained or peak brightness.
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 exact-model specification does not establish this feature. It has not been inferred from another model or from an omitted field.
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.
SourceNeeds the upstream cable connected to a computer for hub data. Port counts and USB generation are listed separately.
SourceAOC also marks a 'USB fast charge port' as present without identifying the port or its charging output.
SourceHeight-adjustable stand; travel is listed separately.
SourceManufacturer-listed travel: 130mm. Not calculated from the external height range.
SourceMatch the screw pattern, screw dimensions, product weight and mount load rating; the pattern alone does not verify a safe mount.
SourcePortrait rotation supported; range listed separately.
SourceAOC's UK page lists the pivot as 90 without a unit or direction.
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.
SourceAOC lists a 4.77 kg 'Net weight excl. package' next to a separate 'Product without stand' figure, but does not explicitly state that the net figure includes the stand; it is kept as reported_net_weight.
SourceAOC's net weight excluding packaging; stand inclusion is not explicitly stated.
