.....Is there anything i need to look out for these days in terms of future proofing my purchase? I've no idea who the leading brands are anymore....
Panasonics are now re-branded budget Turkish TVs.
Samsung are currently the best quality and value-for-money TV sets available with LG and Sony tailing along behind.
If you are in the market for a new TV the decision is whether or not to buy a 4K set for UltraHD which is being introduced (although quite slowly.)
4K sets are much more expensive (roughly twice the price) than full HD sets but the picture quality is very noticably improved. Lack of content is the main issue at present but BT have Sports available in 4K right now, Sky will be introducing SkyQ 4k boxes soon and Netfix and uTube have movies available in 4k also.
Beware that 4k Ultra HD is totally dependent upon high speed phone line access and not everybody has access to upgraded fibre optic phone lines. BT will advise you further if your phone line is suitable.
The choice you need to make is whether or not to buy a FullHD set and save loads but risk it being outdated within a coiuple of years or bite the bullet and buy a 4k TV now which is future-proofed.
Whichever decision you come to, make sure it's a Samsung but do your research and visit a store for demonstrations first.
