FAQ

How do I switch between 4K/160Hz and FHD/320Hz modes?

The monitor automatically detects and switches based on the input signal from your GPU. To use 4K@160Hz, set your graphics card output to 3840×2160 resolution at 160Hz. For FHD@320Hz, change your output to 1920×1080 at 320Hz through your GPU control panel or operating system display settings.

Is this monitor compatible with NVIDIA G-Sync?

Yes. While officially certified for AMD FreeSync, the AOC U27G4 supports Adaptive Sync which is compatible with NVIDIA G-Sync on GeForce 10-series and newer GPUs when FreeSync is enabled in the NVIDIA Control Panel.
