ryans Those are some really great finds! Thanks for posting them. notebook check states that some PWM frequencies go up to 3846000Hz. What on earth do they have that can measure frequencies at that rate?
ryans So I would think it would not use FRC, unless 10 bits of color were somehow requested.
I guess that would be up to the GPU. I am guessing that I would have to steer away from HDR content in the case the GPU attempts to output higher bit colors.
ryans @alireza_atazadeh has a good idea of using slow-motion camera on phones to try to detect this PWM flickering.
This was part of my plan regarding the stereo microscope. Ideally I would like an ultra high speed camera along with the microscope to attempt catching FRC in the act. Since PWM frequencies can be insanely high, I doubt an entry level high speed camera will catch the higher ones in action (Would definitely catch the iPhone 12 though). The camera I was looking at goes up to 40,000 fps at a very low resolution.
