That's not because of the fpga though. You can also plug a CRT into a PC. You can even chase the beam if you're willing to go to a low enough level. People generally don't but this is a limitation born advantage. There's no OS (sort of) to get in your way and why would you put one there if it's not helping you. (I say sort of because there usually is a system that could be described as an OS running somewhere on the fpga board, to load the fpga bitstreams, if nothing else, but also sometimes to supplement the fpga's abilities)
