To meet demand for increasingly immersive and responsive media, the HDMI^® specification has introduced QFT (Quick Frame Transport), a technology designed to minimize display latency. By accelerating frame transmission, QFT effectively lowers input lag, making it especially suitable for applications that demand both real-time responsiveness and high image quality, such as gaming, interactive video, and virtual reality. By shortening the time it takes for a frame to travel from the source device to the display, QFT significantly enhances the user experience, delivering smoother, near-zero-latency interaction.

Complete QFT Test Solution for Zero-Latency Gaming and Video Applications

Chroma has developed a comprehensive and automated solution for QFT signal and optical measurement. The A223814 HDMI signal module, combined with dedicated test patterns and the Chroma A712306 Flicker Measuring Probe, enables quantitative measurement of display latency and displays results directly on the DUT for intuitive comparison. With configurable FVA (Fast VActive) segmentation from 1 to 16 parts per frame, along with a wide range of resolutions and refresh rates from 10K@30Hz to 2K@540Hz, the solution measures display response times that are difficult to assess by the eye alone. Results are calculated in real time and output quickly. The platform also supports testing in HDR, Dolby Vision, and QFT+VRR modes, enabling latency measurements under diverse scenarios. This makes for a precise and efficient test solution that saves valuable time and enhances overall test performance.
