Manufacturer specification · At the native panel resolution. Manufacturer lists 300 Hz. Available modes depend on input, cable and source. Listed vertical input range: 48~300Hz. AOC's page title reads "Full HD, 300Hz (310Hz OC)", but the specification table, tagline, introduction and the Q25G4SR user manual ("Max resolution 2560x1440@300Hz") give QHD 2560 × 1440 at 300 Hz; no 310 Hz mode is recorded.
Manufacturer specification · The exact-model manual lists 2560 × 1440 at 320 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.
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.
18 verified differences, most decision-relevant first. 7 are also drawn in Visual facts above. Missing information stays separate.
