ok, well at that distanceyou could easily have a 50in tv, presuming you've got the space and want one? if so look at my own tv, the
lg50pk350 plasma, its excellent and only costs £549.95..
it thats too big then look at the
panasonic 42g20 plasma, also very good and costs £599.99..
a very good lcd that you could shortlist is the
sony 40ex503, £579.95 .
.the 46in version is £749.95..
at the very top of your budget the
lg42le8900 is an excellent rear led lcd tv, £999.95..
my advice is to go and demo these, and a few more if you like, and choose the one that you like the most..
id just bear in mind that these tv''s will probably be set way too bright in the shops, id ask the salesman for the remotes and set each tv to the movie/cinema picture preset, its likely thats the kind of picture you would be watching at home, then decide what you like
