On CRTs the pixels on PC monitors were arranged differently to TVs, which is why your Commodore screen was sharper than the typical console hook up. From what I recall (it's been a long, long, time since I've studied this) PC monitors were a typical square grid layout, much like how LCDs are. Where as TVs had the odd and even lines offset by half a pixel - a bit like a hexagon grid.
