AOC's 27G50F is a 27-inch 1920x1080 flat IPS monitor with a 300-nit rating, 4 ms GtG response and a maximum 180 Hz in AOC's overclock mode, plus Adaptive-Sync, MBR Sync and NVIDIA G-SYNC Compatible certification. It connects through HDMI 2.0 and DisplayPort 1.4. It suits first-time or budget gaming builds. Its tilt-only stand and 1080p resolution at 27 inches are the main compromises, and Best Buy's listing describes the panel as 144 Hz.

AOC lists a maximum 180 Hz in overclock mode, while Best Buy describes the panel as 144 Hz, so plan on overclocking through the monitor's menu for the higher figure.
AOC lists it as NVIDIA G-SYNC Compatible and supporting Adaptive-Sync with MBR Sync.
