Hi, My Sony KDL40HX723 has given up the ghost. I'm looking for something that is great for sports but also decent at all round viewing. Don't want to go over 50inch I'm very particular with uneven back lighting and have returned a few sets in the past because of this. Would have to be local dimming I think. I have a surround sound system so audio is not important. Would like 4k for future proofing Any recommendations. Ideally want it before the World Cup starts!
