thread Depending when you last bought a TV
it might be worth going into a shop with a tape measure (currys have paper ones up by the fridges), bezels have got much smaller in the last ten years so you may be able to go up a size. But there aren't many 40"s, it's usually 43".

Probably worth waiting til black friday (or at least a week for retail Christmas to kick in).
permalink yeah, i've measured over the bezel of this one...
going to 40 would be relying on the 'bezel dividend' quite heavily.
