THE DIFFERENCES, MADE VISIBLE
Visual facts
Differences first. Select a topic for its graphic, sources and conditions.
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.

Max refresh
Maximum manufacturer-listed refresh rate, not measured motion clarity. The port-specific limits below matter; HDMI and DisplayPort can support different modes.
AOC U27G4XM160 Hz
Manufacturer specification · At the native panel resolution. Manufacturer lists 160 Hz. Available modes depend on input, cable and source. Listed vertical input range: FHD: 48-320Hz / UHD: 48-160Hz. The exact product page separately lists Full HD at 320 Hz in Dual Frame Mode; this is not 320 Hz at the native UHD resolution.
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.
4 verified differences, most decision-relevant first. All are also drawn in Visual facts above. 1 feature is the same under different published names, grouped below. Missing information stays separate.
