You may get different results for Raspberry Pi or when using USB2.0 port, but we are testing grabbers performance and we do not want that they could be limited by the host or USB2.0 bus slow performance. USB grabbers are connected to the USB3.0 port. we use highly performance hosting unit: i7-6700HQ, 16GB RAM, Windows 10 configuration.the HyperHDR bechmark page runs on the same unit running the HyperHDR application to avoid network related latency.since HyperHDR is using high performance video processing, you can not use the result to assess how the particular grabber will work with the other software.The final result includes: the screen refresh rate latency, the grabber internal & capturing rate latency, USB transport latency, system drivers latency and HyperHDR video processing latency. calculate the total average latency corrected by the test environmental delay.start to display the color sequence: each color must be captured & confirmed by the HyperHDR application to proceed with the next sequence.compute the test environmental latency including communication and the browser graphic performance (usually few ms).you must position the black rectangle in the center of the screen (don't worry: the margin is quite large, the benchmark won't procceed without it).the grabber is capturing the desktop including the web browser.
