@ID_AA_Carmack I’m researching home-made Arduino scanning backlight (90%:10% dark:bright) using 100-200 watts of LED’s. 120hz.net/showthread.php…

@mdrejhon Good project. You definitely want to find the hardware vsync, don’t try to communicate it from the host.
EDIT: Project is now published at: Electronics Hacking: Creating a Strobe Backlight
