Re: Refresh Rate 3,072 Hz?
Good catch!
Jumbotrons and Video walls are already refreshing internally from 600Hz - 3000Hz+ for PWM dimming purposes; unfortunately this does not (yet) mean frame rate. However, this is direct LED driven PWM which can easily be separate refresh cycles instead. it's only a minor engineering change to make a Jumbotron do 1000fps 1000Hz -- faster SPI buses (or Ethernet), and unique-frame-per-refresh controllers.
I already discuss the theoretical retina-refresh-rate Jumbotron concept here: Custom OLED Rolling Scans -- Custom Built OLED Monitor -- But applied to a Jumbotron / Video Wall instead

Re: Refresh Rate 3,072 Hz?
3072hz is 128 times the refresh rate of 24hz.
What is the benefit of running 24fps material(such as Films which is what Samsung Onyx are used for in Cinema Screens) at such a high refresh rate?
Does running internally at that refresh via PWM improve motion? Do they still use some sort of BFI in Cinemas to simulate the double/triple shutter effects?
Additionally, I thought PWM flicker was understood to be hurtful to the eyes so why would Cinemas use a display with PWM?
