Key strengths

The 3440 × 1440 panel supports a listed 360 Hz native-resolution mode. Check the input-specific conditions alongside the figures.

A listed charging output reaches 15 W on the specified USB-C or Thunderbolt port. Match the laptop and cable to that port’s power and display capabilities.

The checks that matter.

Before you buy

The 15 W charging ceiling may not replace the original charger for a laptop that needs more power. The rating applies only to the stated port.

Allow for the 294.3 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.

Colour depth
Not listed by the manufacturer

AOC's UK specification lists 1.073B colours (10 bits), but the page's WQHD feature text says "True 8-bit color". AOC links no user manual for this model, so the disagreement stays unresolved and no bit depth is chosen.
