Sounds like a great idea, since TFTs for PCs are much cheaper than LCD TVs and appear to have way better image quality.
I've actually seen a Logitech version of one of these running through a 15" TFT and it was pretty cool, i think the display let it down though as it didn't handle scaling or fast action very well, but i hear you can get 17" 8ms displays now for £150
Also, I already have a great CRT TV for gaming but its pretty big for my room in halls so i put it in the common room and i'm thinking of an LCD for the room to save valuable desk space.
Can anyone think of any cons?
