    I've bought a new LCD TV and unfortunately now see the extremely poor compression techniques used by NTL, re: picture quality :(

    I've read some posts on here, that talk about adding a scaler to improve PQ...however, it seems the ones I looked at are incredibly expensive ! Can someone tell me if this is the only way to improve PQ, or is there another cheaper method ? ;)

    Thanks

    A scaler is a box which converts one screen resolution to another. It can also change other factors i.e. change an interlaced picture to progressive, or vice-versa.

    However, you can't put information into a picture which wasn't there to start with. It's far better and cheaper to get a picture source which is less compressed (i.e. Freeview or Sky).
