THE DIFFERENCES, MADE VISIBLE
Visual facts

How to read this comparison
Manufacturer facts for the exact models shown. Not a quality rating or a test result.
“Different” means the known values differ, not that one is better.
Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

Manufacturer specification · Manufacturer port counts and versions. Confirm source-device support, cable bandwidth and the exact mode; a connector name alone does not guarantee every advertised configuration.
Match the monitor to the connection. Refresh limits depend on the input, cable and source device. Confirm the exact regional ports, stand adjustment and mount. Manufacturer response-time methods such as MPRT and GtG are different; neither the image nor these figures establish an independent motion or colour-quality test.

Manufacturer specification · Manufacturer dimensions in the stated orientation; allow additional room for cables and movement. A listed height range is retained without inferring an adjustment travel.
AOC describes an E-sports monitor stand whose base is designed to reduce the monitor's footprint on the desk and lets a keyboard sit on top; the stand includes cable management.
Response time, HDR support and colour figures are manufacturer claims with different conditions; they do not establish independent motion or image-quality results.
AOC’s vertical-frequency field conflicts with its manual (48–300 Hz versus 48–320 Hz). The 320 Hz maximum is supported by both the headline specification and manual; the complete operating range is left unconfirmed.
Compatibility and maximum operating modes depend on the source’s stated hardware, firmware and connection requirements; manufacturer figures are not independent measurements.
