High frame rate (HFR) projectors, supporting refresh rates of 120Hz or higher, are designed to eliminate motion blur and judder in fast-paced content like action movies, sports, and video games. Traditional projectors operate at 60Hz, which can struggle with rapid movements, causing artifacts or stuttering. HFR technology doubles the refresh rate, rendering each frame twice as quickly for fluid visuals. For gamers, this reduces input lag—the delay between pressing a button and seeing the action on-screen—critical for competitive play.

　　A key application of HFR projectors is in gaming, where titles like Call of Duty or Fortnite benefit from silky-smooth animations. Many HFR projectors also incorporate variable refresh rate (VRR) technologies like AMD FreeSync or NVIDIA G-Sync, synchronizing the projector’s refresh rate with the GPU’s output to eliminate screen tearing. For sports enthusiasts, HFR ensures clarity during fast camera pans, such as in soccer or basketball broadcasts, where players’ movements remain sharp.

　　Future trends in HFR projectors include higher native resolutions, such as 4K at 120Hz, combining ultra-high definition with ultra-smooth motion. Improved HDMI 2.1 support enables higher bandwidth for uncompressed HFR signals, while laser light sources enhance brightness and color accuracy. Additionally, AI-powered motion interpolation algorithms can generate intermediate frames to simulate HFR from lower-frame-rate content, though purists may prefer native HFR for authenticity.
