I hope this isn't too controversial...

Post funny things about programming here! (Or just rant about your favourite programming language.)
DVI-D uses TMDS, which is a serial protocol. So if you want to be really pedantic you could call it a serial port even though it's not RS232.
DVI-A also transmits metadata over a serial connection, but the video signal is parallel analog.
Fair! Neat fact!
