Using the mode allows better detection of refresh rate and refresh interval for the CVDisplayLink bridge to GdkFrameClock. Using it can help ensure that our 144hz displays can actually reach that rather than falling back to just 60hz. This will also need future commits to rework the displaylink source to be per-monitor.
