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 U27G4R160 Hz
Manufacturer specification · At the native panel resolution. Manufacturer lists UHD@160Hz / FHD@320Hz Dual Frame Monitor. Available modes depend on input, cable and source. Listed vertical input range: UHD: 48~160Hz / FHD: 48~320Hz.
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.
