I understand the point you're trying to make, but it's important to be aware that ALL digital video you consume today is subject to compression, some better / worse than others. 4K is and will certainly be no different.
Like you correctly said Netflix is more heavily compressed than say Blu-ray, but Blu-ray still uses h.264 compressed video albeit at a higher bitrate. But Netflix 4K is a large step up in quality than their 1080p streams. You mention uncompressed 4K... just so you know, the last time we had any sort of uncompressed broadcast video was before analogue was turned off and that was only at 720 x 576 (414,720 pixels/frame) effective pixel resolution and the source material before broadcast was, at least in the past 15 or so years before analogue shut of with Digital Beta, compressed anyway.
Let me illustrate... 4k @ 3840 x 2160 (8,294,400 pixels 16bit colour = 47.5MB/frame @ 24fps = 1.14GB/second / 68.4GB / Minute Therefore a 90 minute movie is about 6.156TB even if you used 50GB Blu-rays you would need 123 discs just to hold 90 minutes of uncompressed 4K video).
Compression is not a dirty thing, it's a necessity and when done well unnoticeable by the viewer.
Please don't think I'm being patronising, I genuinely hope this helps your understanding of digital video.

4k players out xmas and discs but film industry are slow to jump on so 4k wont be mainstream for years so any set now wikl be out of date ,if you belive netfkix 4k stream is real 4k think again itz comressed so probally a little better than 1080 because they stream at 15mbs a full uncompressed 4k stream will be alot bigger .but bt sport 4k launches soon

So does it upscale everything to 4K? I expect not so the only thing that i could watch in 4K is my copy of Captain Phillips which is the only blu ray i have in 4K.
If its £799 with 4K what would it be for normal HD i wonder - what is the cost of 4K?

Unless I missed something, there aren't any 4k blu ray players or blu rays out yet. There are some blu rays cheekily marketed as 4k master, but they're still only 1080p on the disc.
Also, all 4k tv s upscale everything to 4k, it's just the quality of the upscaling that varies, if they didn't, only 1-in-4 of the pixels would be lit.

Unfortunately, it will probably only look amazing in the shop when they are running a video carefully designed to make the TV look amazing (via USB) -- but when you get it home, you'll soon realise there is little-to-no amazing footage being piped into your home for entertainment consumption!
The TV will probably never get a chance to show what it can do in reality, It would be the equivalent of driving a McLaren F1 exclusively to the local supermarket and back :smiley:

Panasonic make very good TV's. Usually much better than the likes of Sony, Samsung and LG. Although the new LG oled curved TV is jaw dropingly beautiful and the picture quality is simply out of this world, but seriously expensive.

it will do UHD but only via the HDMI inputs, it doesn't support YouTube 4K, Or Amazon 4k within the TV, Netflix it might do, but its hard to tell with the poor screen.

this is a badged TV, its not made by Panasonic, and does not have any of Panasonic Smart platform, its just a vestel TV, having seen them on a daily basis I would save the money and put it towards a better TV.

CX680 upwards are quad core, have Firefox OS and will get Freeview Play. However the 680 has poorer motion IIRC.

I bought the cx700 at the weekend which I imagine is similar to this. The picture is great, colours especially but the motion isn't great coming from a Sony.

That doesn't seem that great to me.

Nice, very tempted.
Also, if you buy £800 worth of Gift Cards at Morrisons, you get a voucher for 80 PENCE A LITRE off your next purchase of fuel up to 100 litres. So, anything up to £80 off your next fill up if you have a big tank or some jerry cans.

I think there are no reviews as its a recent set (not many reviews for 2015 sets such as sony, samsung etc), seems like a good deal too big for my lounge though
sancheez to Dubplated
30 Jul 151#10
Yep. Very new. Struggling to find any reviews.
But the 400 is the bottom of the range set. Someone on AV Forums checked out the CR400 (bottom of the range curved version of this - CX is flat, CR is curved, but most of their spec is otherwise the same) in a store and they weren't hugely impressed.
That said, it does seem like a decent price for a new model, 55", 4k, Panasonic. But, personally, I'd be waiting for reviews before I pulled the trigger. Would be annoying to jump the gun and find out they produced a dud ...

It's the new entry level model from Panasonic, I expect reviews will follow soon. Generally with Panasonic models, the higher the number on the end of the model name the better it is. The 400b is their bottom of the range model.
