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.

AOC U32G4U3840 × 2160
Manufacturer specification · Manufacturer resolution notation: 3840x2160. See the separate refresh-mode conditions for any lower-resolution configurations.
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.
16 verified differences, most decision-relevant first. 7 are also drawn in Visual facts above. 2 features are the same under different published names, grouped below. Missing information stays separate.

Manufacturer specification · At the native panel resolution. Manufacturer lists 160 Hz. Available modes depend on input, cable and source. 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.
Manufacturer specification · AOC's product page lists a 180 Hz OC maximum; 144 Hz is treated as the stock rate. The 180 Hz OC mode is listed only on AOC's product page; the 27G50F user manual gives a 1920x1080@144Hz maximum and a 48~144 Hz vertical scan range and does not mention 180 Hz. Per-input limits are not published on the UK page.

The headline maximum spans different resolution modes: UHD 3840 × 2160 at 160 Hz / FHD 1920 × 1080 at 320 Hz (Dual Frame Mode). The faster lower-resolution mode does not deliver the same pixel detail as the native panel mode.
AOC lists a 36.2 mm depth without the stand and a typical power figure of 21 W on its product page (20 W at default brightness and contrast in the manual), and describes an e-sports stand whose base reduces its desk footprint and includes cable management.
The 27-inch 1920 × 1080 panel has a 0.3114 mm pixel pitch (AOC's separate 93 ppi row does not match that pitch), and the colour depth is listed as 16.7M (6 bits + FRC).
AOC names HDR10 input support but lists no DisplayHDR certification or HDR peak brightness, and the 180 Hz overclocked mode appears on the product page but not in the user manual, which gives a 144 Hz maximum.
