48.9-inch QD - OLED · UK specification
A 48.9-inch QD - OLED monitor with a 5120 × 1440 panel and a listed 240 Hz native-resolution mode. Its specified depth with stand is 314.5 mm.

Specifications checked 27 Sept 2026Manufacturer specifications, not a hands-on test.
The 5120 × 1440 panel supports a listed 240 Hz native-resolution mode. Check the input-specific conditions alongside the figures.
A listed charging output reaches 90 W on the specified USB-C or Thunderbolt port. Match the laptop and cable to that port’s power and display capabilities.
The default USB-C High Resolution mode runs the USB-A hub at USB 2.0 speed. Choose High Data Speed for USB 3.2 Gen 1 peripherals and check the manual’s display-format requirements.
Allow for the 314.5 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.
AOC’s vertical-frequency field conflicts with its manual (50–76 Hz versus 48–240 Hz). The 240 Hz maximum is supported by both the headline specification and manual; the complete operating range is left unconfirmed.

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: 5120x1440. See the separate refresh-mode conditions for any lower-resolution configurations.
SourceManufacturer panel designation; technology alone does not establish tested image quality.
SourceThe exact-model manual lists 5120 × 1440 at 240 Hz, agreeing with the product-page maximum. Available modes depend on input, cable and source. The separate vertical-frequency field is conflicting; see its source note. The manual requires a DSC-capable graphics source for 5120 × 1440 at 240 Hz with 10-bit RGB/YCbCr 4:4:4 using DisplayPort 1.4 HBR3 input.
Manufacturer 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 device, input and driver; console VRR support varies.
SourceThe manual lists 48–240 Hz, while the product-page vertical-frequency field lists 50–76 Hz. This source conflict remains unresolved; no common operating range is inferred.
The same facts in the manufacturer’s combined or original wording, each with its source.

Manufacturer claims. Full-screen, HDR peak and different APL window sizes are separate conditions, not directly comparable luminance tests.
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 listed connections include USB-C or Thunderbolt. Video, data, upstream/downstream roles and charging power depend on the particular port.
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. The product page names a DisplayPort 2.1 UHBR20 socket; the manual timing matrix describes DisplayPort 1.4 HBR3 input with DSC. The timing matrix is not used to relabel the physical port version.

SourceNeeds the upstream cable connected to a computer for hub data. Port counts and USB generation are listed separately.
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.
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.
SourceManufacturer dimensions in the stated orientation; allow additional room for cables and movement. A listed height range is retained without inferring an adjustment travel.
SourceThe manual Settings page states that the default High Resolution mode supports 5120 × 1440 at 240 Hz. Its timing matrix also lists 240 Hz RGB/YCbCr 4:4:4 in High Data Speed mode, so no blanket 165 Hz USB-C limit is inferred. Check the exact colour format, source and cable.
