I have a PS4 and like to watch movies via Blu-ray's or mkv files
Can you go bigger than 49"?
If so you could look at the 55" NU8000 which is going for £700-£800 and this is by far the best tv right now for gaming purposes, it's a good buy and was priced far more at one point than the others but you are buying at the right time due to clearance pricing starting, failing that the XF85 or the U7A from Hisense which is about £600, all of these have 120hz panels.
Or save a load and buy a 50" model like the UK6950 from LG or A series from Hisense, going for around £350-400, it just depends on your content at the end of the day, you can easily overspend.
XF90 is the bare minimum for HDR content if you plan on viewing any of this in the future.
