HFR stands for high frame rate. It is generally attached to content and screen technology that can refresh faster than 24 frames per second.

HFR (High Frame Rate) refers to content that uses a frame rate faster than the standard of 24 frames per second. These contents provide a much smoother picture and can show more detail in each scene.

In motion picture technology—either film or video — high frame rate (HFR) refers to higher frame rates than typical prior practice. The frame rate for motion picture film cameras was typically 24 frames per second (fps) with multiple flashes on each frame during projection to prevent flicker.
