Hi, my lovely wife is buying me a TV for my 40th. However, she has stated the budget and left it up to me now. I have had a Panasonic 500 series for 11 years now and never failed us. I am looking to upgrade to a 4k tv. Budget is £550 or close to. Screen size max 50" Brand Panasonic, Sony or Samsung. If there is another one out there that can match or beat the bigger names ideal. Needs to be 4k, ultra hd/ her. Also needs to be smart TV preferably android but not too fussed. Must have at least 4 HDMI sockets. Thanks in advance. We have seen this Sony Bravia 49 inch Android 4K HDR Ultra HD Smart TV with Youview, Freeview HD, PlayStation Now (2016 Model) for £550. It ticks the boxes that I'm looking for. Just need advice.
