There are no major problems or specific incompatibilities between the AOC CU34G2XP/BK display and NVIDIA graphics cards, including the RTX 4070 Super.

Here are some key points to consider:
- The display supports DisplayPort 1.4 and HDMI 2.0 connections, which are compatible with most modern graphics cards, including the NVIDIA GeForce RTX series.
- The display uses Adaptive-Sync technology, which is compatible with AMD FreeSync, but does not specifically support NVIDIA G-Sync. However, as of 2019, NVIDIA has opened up G-Sync compatibility with some FreeSync monitors, so it could work with some setups, but this is not guaranteed.
- For optimal use, make sure your graphics card is powerful enough to handle the display's UWQHD (3440x1440) resolution and 180Hz refresh rate.

To sum up, your RTX 4070 Super should work without any major problems with this display, but you may need to adjust some settings to optimise performance.
