This frequency did not change during the operation.
The video card produced frames at the rate it could manage.
However, the overall synchronization frequency via HDMI remained stable.
However, monitor manufacturers were not fully prepared for this change.
Upon implementing VRR, they realized that displays reacted poorly to significant frequency changes, leading to flicker.
This is intentional because when frames change at a lower frequency, some people may notice flickering.
Forty-eight frames per second is the minimum at which video is comfortable to watch.
Also pay attention to panel quality and monitor performance.
