Hello,

I’m adhering to the hardware requirements outlined in [this documentation](https://dev.epicgames.com/documentation/en-us/unreal-engine/ndisplay-synchronization-with-nvidia-gpus-in-unreal-engine). However, most sync generators I’ve found support a maximum refresh rate of 60 Hz, and I haven’t come across any that exceed this limit.

My understanding is that if a sync generator is limited to 60 Hz, it would cap the display output at 60 frames per second (fps). For our interactive real-time gallery, we require a higher refresh rate to ensure smooth visuals.

**Seeking Advice:**

1. **Sync Generators Supporting Higher Refresh Rates:** Could you recommend any sync generators that support refresh rates above 60 Hz?
2. **Reliance on NVIDIA Quadro Sync II:** Is it feasible to forego an external sync generator and rely solely on the NVIDIA Quadro Sync II for synchronization needs?

Any assistance or recommendations would be greatly appreciated!
