This is a John Lewis deal.

I'm done with Samsung - great picture but poor long term support; they're no longer making the evo kits they promised to make my set upgradeable, skype are ditching the platform - TV suddenly not so 'smart' any more

Shabby attitude to customers investing in their platforms - TVs aren't replaced as often as mobile phones; I think I'll go for the dumbest TV I can find next time or go with Android

Good price but not a great TV, reviews suggest picture image issues, sports viewing blur, light leakage

Trouble is to get a great 4K TV HDR etc. You probably have to look at >£3-4K which is the trade off unfortunately

Amazon is a good place to start

I have the 40" JU6400 which is a higher model than this which I use as a PC monitor and I haven't received a firmware update for HDR. Can't seem to find any info about it on avforums / avsforums either.

John Lewis page for the JU6400 also mentions HDR support with a firmware update.

It's great as a monitor. I don't use any scaling settings for Windows but I do use scaling for web browsing, set at 125%.

It replaced a 1440p BenQ BL3200PT monitor. The Samsung is much better.

I've already applied the Feb 2016 update to my set. Still no HDR support.

Thanks for all of that.
Here's a thought...it is advertised as an HDR tv on the John Lewis website.

If I buy it, and if it doesn't get an HDR update within a month or so, then I could probably send it back as being not as described.
Could be an option?

With the way it has been described? I think so but you need to bear in mind that the JU6000 series doesn't support 4:4:4 chroma-subsampling (labelled HDMI UHD Color on Samsung TVs) like the JU6400 series and up so text won't be as clear as a PC monitor.

Not really worried about text to be honest, because i ll be using the tv as a tv, rather than a pc monitor.
All I want is a really good picture when I stream 4k hdr, from my 4k Amazon fire box.

​Yeah - I was looking for a review from an actual recognised body (Avforums etc) rather than Amazon customers - they're a mishmash as they lump every review of every JU6000 series regardless of whether it'd the 40inch, 55inch etc. There's even a review of a Sony TV in there! Guess there's no official review of the 65inch model.

I have a room ready for a 90inch TV under £1000 and that dream is edging closer every day with these price drops! Last year a 55inch 4k TV was £1800. Come on Samsung, Sony, Panasonic and LG - Fight for my money!!!

the fire box doesn't support HDR afaik

Support's fine at the beginning, but I'm talking 2 years down the line.

My ES8000 was a year old and was irreparable and they switched off some nice home automation features from the firmware update, and the replacement F7000 only got one evo kit (which wasn't worth it). So much for "futureproof".

It may do in the future.
I m just trying to future proof as much as possible

This TV is quite new though, so its to be expected, and it was obviously manufactured with that in mind or they would not have been able to update it like that (its hardware dependant not just software).
Now, like the guy you replied to, I have a Samsung TV that is losing all its smarts. Its an ES8000, which i believe was a 2012 model, and the top of the range at the time. Samsung has been turning off all the 'gimicks' supports at first, which i didnt care about, but the bigger issue is the quality of the common apps. Netflix is extremely unstable and has been for about a year. Amazon was recently updated to the new look&feel but as a result it slowed right down. The OS itself has also slowed dramatically, and I have to admit I think its being done on purpose from Samsung. I have had no additional features added yet the speed has dropped through the floor. Its unacceptable for a £1800 TV for that to happen when no new features were added. Its either on purpose or just negligence.
I also had hardware failure after 18 months, I know thats not an issue here, but just throwing it out there that in my eyes, Samsung has very little substance behind the large prices, in my experience. You are best buying mid-range every 2-3 years from them.

Thanks for all of that, your input is much appreciated.
Its sad that manufacturers dont support thier devices, regardless of cost.
Mobile phone manufactureres are a prime example of that. Some regularly update their devices and some dont. Its the luck of the draw.

I do not support big brands. Cold for me.

Not anymore. Also cheaper deal for this TV on ebay is £750.
