I have an Asus pg258q. According to Asus it has connectivity options including DisplayPort 1.2. As I understand it DisplayPort 1.2 does not support frame rates above 240fps at 1080p since it would exceed the maximum bandwidth. My gpu supports DisplayPort 1.4. So what exactly happens if my fps exceed 240fps? Does the gpu start to render at a lower resolution? Does it drop frames? Is there a bottleneck that could cause potential lag?
