Looking to replace our TV and can accommodate a 43 inch in the allocated space. I have done a bit of research across the net but it seems anything less than 55 inch isn't covered these days or rubbished.

Looking for advice on what features to look out for please eg is it worth stumping up for 4k. Ideally would like something that handles sport well and I don't do gaming.

Currently have a good freeview signal and I guess will also have to upgrade the DVD player to Bluray to take advantage of increased quality?

Any advice appreciated
