That's ironic that this video is only available in 720p.

Dad just brought this tv the other day! I can't stop watching it! The picture is soo sharp and clean and the resolution of this screen blows all HDTVs out of the water! Also got word that NFL network this year is supporting 4K! Cant wait to see this! This is about to be sweet! Also I can't wait to see what my PS4 looks on this tv! Might pass out haha

Japan is already experimenting with broadcast 4K, and Super Wifi in some parts of Tokyo.

did you watch any of the promo videos ? :P or tech demos or words being sharper and stuff

[BlazinNSoul]

Thinking of buying one but have some issues yet. What is the refresh rate? Anything below 60 won't cut it for gaming.

Furthermore you won't be gaining much until the source catches up with the native resolution. Another big snag is that currently most 4k sets are only 120Hrz.

Which brings into question how well they will reproduce fast moving scenes. I see this being more of an issue with gaming and sporting events.

Also the curved sets I think are a gimic. Not worth the premium you pay for them.

i think i noticed that too.... hmmm i dont think the 4k media player is being used i think its another media box hmm....

[PaulLovesRoe]

So someone explain this to me, Their is no Content avaiable yet to buy, But it costs over 5 Grand & ive even heard one costing 30 plus Thousand.What if i put in my Blu Ray Movies, Will it convert from 1080p, To its 4k Resolution?Or just look in 108p?Or if i hook it up to my Ps4 Game System next month.Why buy this, If its not gonna make all the stuff i already own look any better?

[ReticulatedViper]

There is a disk for 4K resolution, it's called HVD.

[ParanoiaGentlman]

hmm but what i guess should peak you excitement might be the fact that the sony tv uses a QDLED screen. its brighter and more energy efficient than oled :O

[jmpompey]

It's all about the size of the TV, 8K has been called the ultimate TV because assuming you don't have an insane 150+inch tv the resolution is indistinguishable from reality.

[Jokamutta]

But can't u already watch 4k videos on Youtube they are called "Original" and it's over the 1080p ?!

[declanwatson]

Sony is the leader in 4K. They are also making a 4K format Disc because Sony are the people that created all formats

[yusriaffandi]

Cannot imaging 8K TV... so fast TV techolongy

[oOJakkeOo]

They will probably look like 720p movies on 1080p displays. Which means, they will probably look great.

[shadowscarnage]

I'll just wait until 4k is the mainstream and 1080p becomes the past just like standard definition.

[Gwynne]

The FIRST thing everyone needs to know about UHD is that it isn't 4K.

4K resolution is 4096x2304 - or 9, 437, 184 pixels.
UHD (or 2160p) resolution is 3840x2160 - or 8, 294, 400 pixels.

See the difference?

The reason it is called 4k is that the original intent was to use that resolution but then the techies realized that up-converting from 1080p to 4K would be problematic. So they settled on an even multiple of 1080p to make up-conversion easier.

Call it UHD or 2160p - just don't call it 4K.

[zeddark]

still waiting for 4 k movies in 2017;p

[Soraviel]

i expect 4k tv to be in my price range in 2021

[Mohamedelesnawy]

doesn't anyone find it ironic that this video is not in 4k :P

[jestificated]

Your chart shows that it is 3x higher, but the math shows it is double 1080p (x2)
