I was looking for a 55' TV for less than £700. It supports HDR 10, which is rare at this price point (might be able to get a Hisense which I did seriously consider), and features backlit LED so viewing angles are good.
Price is usually £799, but currently going for £699 online. You'll then need to add the discount code LSTV30 to get £30 off to bring the price down to £669.
Topcashback also offered at 1.57%, so potential to get this down to £659.
Decent review on the 49' version of this on AV Forums:https://www.avforums.com/review/philips-6501-49pus6501-uhd-4k-hdr-tv-review.12949
Hope this helps anyone on the look out!
