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.

Maximum manufacturer-listed refresh rate, not measured motion clarity. The port-specific limits below matter; HDMI and DisplayPort can support different modes.
AOC AG256FS360 Hz
Manufacturer specification · At the native panel resolution. Manufacturer lists 390Hz (OC, 360Hz 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: 48-390Hz.
Manufacturer specification · At 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).
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.
