Has to be fake surely? But I want it to be true so bad!
Nice find 1BYONE, thanks for sharing.
I build LED screens from scratch and I'm sorry to say I'm 99% sure that this is fake. Any LED screen I've ever seen is driven from a graphics card on a PC (you actually set them up like a dual monitor) and while it's possible to do the video over RF it's both difficult and pointless for fixed installations.
