Yes if you tear apart the two components the TV top from the control deck bottom there's this rectangle hole molded there with a pair of wires that go between the two. That wire sends the video feed on one and the audio on the other I imagine to the motherboard on the TV side so it does its thing when the NES is turned on. Visually it doesn't blur like RF does when screwed into a TV, I guess it's as sharp as a non-bleeding RCA connection. The screen on all of them is 19" and it's rounded, not flat as it came before TVs started going that way.
If magazines did that that's cool, I never really looked into it. I just looked at some old game magazines and the coloring on the sharp seemed to align pretty well compared to a normal TV so maybe it's just tweaked to be that way.
