The main component of these latency measurement setups is the LDAT (Latency & Display Analysis Tool) by NVIDIA.
The traditional way of measuring system latency, i.e. recording the input and display using a high-speed camera and then counting the individual frames, is costly, slow, inefficient and tedious.
To simplify the process of measuring latency, NVIDIA has created a dedicated tool called LDAT: a discrete hardware analyzer that uses a luminance sensor to quickly and accurately measure the "motion-to-photon" in an application.
