Has anyone checked theses out??

Uhd 4k TV's!!! I want one
They cost thousands though
It's like the tv is a window to the outside. Picture is amazing, and because of the Uhd (ultra high definition), you can view the screen from really close up and it doesn't seem to affect your eyes.
I was just looking at a couple in Currys. They showed some street scenes, and it actually felt like you were there! Love em

 

I agree they are amazing, but what is the point when the TV programmes are crap!!!!

Shame no one broadcasts in UHD

 

All valid points but it makes no difference because I won't be able to afford one until the price eventually drops 'right' down
It will be interesting to see broadcasters input

 

I rarely buy brand new technology. I wait for the inevitable price drop, and as you say, it's already happening. If I had a spare 2k , I would be very tempted though
But........ As @JazzSi points out, the content needs to be there.

 

I read that sky will be releasing a 4k UHD box in the near future.
IMHO it will be a long time before any broadcasters will use the technology yet though.

 

Will that support 8k?? I believe the technology is already out there, or at least 'being developed'.

 

All this 4k and 8k stuff is great in the studio where everything is wired via SDI.
However, at home, everything is wired up via HDMI (due to DRM issues, SDI is not permitted for home use) and since 4k takes roughly the same bandwidth as 4 X HD signals, I'm willing to bet that 99% of people's HDMI cables and the whole chain in fact will not support the higher data rates required for 4k.
Over and above this, upgrading to 4k is very costly for production houses, studios and broadcasters so don't expect to see much soon.

 

Actually it's a bit of a double whammy for broadcasters as they transmit channels in groups or streams and the higher the resolution of each channel, the less number of channels they can cram into each stream and thus either have to lease yet more space on the satellite for extra transponders (read more money) or drop other channels to compensate.

Now another "little" technical hiccup that the promotional blurb "forgets" to mention is the fact that in a perfect environment, things like transmission loss, conversion phase noise and bit error rates don't count, but in the real world, they become more critical as bandwidth and symbol rates increase and in a situation like DVB (T or S), these all come into play and one will experience more "drop outs" in say 4k than HD.
