The AOC CU34G2X/BK is not ideal for use with the PlayStation 5 (PS5). Here are some important points to keep in mind:

- HDMI version: The monitor has HDMI 1.4, while the PS5 uses HDMI 2.1. This can lead to compatibility issues, especially at higher frame rates and resolutions.
- Frame rate and resolution: The monitor does not support 120Hz at the native resolution of 3440x1440 with the PS5. There are issues with image stretching and Variable Refresh Rate (VRR) when used with PS5.
- Picture quality and adjustments: The PS5 sends QHD video (2560x1440) that is scaled to the monitor's ultra-wide format (3440x1440), which can result in a distorted display.

To summarise: The AOC CU34G2X/BK is not the best choice for use with the PS5 due to technical limitations and compatibility issues.
