That went for any TV receiving a digital signal, not just monitors. Your old analogue connection would actually "leak" from the recever/demodulator (I know, I simplified things) so the TV transmission signal could be picked up with the right equipment. Digital TV, through a SCART/RGB, does not do that. Of course, the stories about the actual "detectors" they used are disputed, but in theory they could pick up a signal from your TV and tell which channel you were watching.
And, as posted, you can buy nice monitors from Samsung that are monitor, TV, FM radio with SCART and RGB on them. The picture quality is fantastic, trust me.
And you can't beat it for watching things like F1 so ya have the TV on PinP while you keep an eye on the live timing off the net.
