Looking to buy a TV for my bedroom it will be mainly for PS4, XBone games, plus general TV watching, needs to be between 40" and 50" 4K, smart etc, maximum i really want to spend is £500, though this is flexible.

I've always liked Samsung, but i am open to different ones, are there any makes i should be avoiding?

I have a voucher for Curry's so will be buying from them, is their breakdown cover worth it?

Thanks for looking.
