4k TV's- worth it?

Thinking about this TV. I don't know much about TV's but I know this is the new great technology.
I've also heard that most media isn't even available in 4k HD though.
Anyone know much about these and have some experience with them?

70"
$3500
nice brag.
i just bought a 55" and it comes in tomorrow. from what ive read i think i made a good decision. for $100 more a pretty much future proofed my set in case 4k does take off. if not then i still got a great 55" tv for $900
if you have direct tv, id look into a samsung tv because i think they have a deal only with samsung to provide 4k content

A couple things:
1) you're right in that most content isn't even available in 4k yet outside of Netflix/a few other things...and I think even that is just upconverted, not actually filmed in 4k.
2) 4k is bordering on the line of the pixels that the human eye can detect or may even be above it. Once you hit a certain point, your eyes can't tell the difference.
If I had the money, I would probably invest in one of the cheaper 4k sets, but going out and dropping 5k on a technology that doesn't even have steady programming yet is dumb IMO.

House of Cards was filmed in 4k. Most big budget films are filmed in 4k or 8k, but you can only buy 1080p copies now.

It all depends on viewing distance and screen size. A pixel on a 100" 4k TV is going to be bigger than a pixel on a 60" 4k TV. Here is a nice chart to illustrate the optimal viewing distances vs # of pixels.

Go to best buy and look at them... you can definitely tell a difference. Granted anything higher than 4k we might not be able to, who knows

I've never seen this particular chart before, but it definitely contradicts every other chart I've seen. It's saying that on a 30-inch screen, viewed from 25 feet away, the human eye can see the difference between 1080P and 4K. Wtf.

I was about to say the same thing. That chart makes no sense at all
So a 1080 20" tv is only optimal at 15+ feet?

so ignoring these charts is UHD Upscaling noticeable? Ive compared the tvs at best buy and can without a doubt tell a difference in the 4ks

UHD Upscaling
UHD Upscaling delivers the complete UHD picture experience with a proprietary process including signal analysis, noise reduction, UHD upscaling and detail enhancement to seamlessly upconvert SD, HD or full HD content to near UHD-level picture quality.

UHD Dimming
UHD Dimming precisely scans an incredible amount of zones across the entire image and adjusts brightness to deliver deeper darks and brighter whites. It virtually eliminates the "halo" effect and image distortion, so you’ll enjoy a crystal clear picture.

From the AVS forums
The NHK chart is what I posted. Like is stated in the quote, it's about how many pixels you need to make the image imperceptible from reality. I didn't look that closely when I posted it. Here is a more realistic chart.
quote:
The NHK chart is based around recreating reality. Not what's good enough in a home environment for really nice image quality, but to fool the eye into thinking what you are seeing is real. So that you can never see the pixel-based nature of the display.
I think a more realistic target is 100 pixels-per-degree which gets you 90% of the way there, if you look at the data.
I seem to recall the Carlton Bale charts being based around 60 PPD, so as I have been saying along, you basically double the distances on his chart.

Im not sure to be honest. Im sure its a little better than 1080, but not quite at clear as real 4k. IMO i would hold off on getting a 4k tv for now, especially the expensive ones since they will eventually all be cheaper. Unless your someone who just watches netflix all day and all night, you really wont get full use out of it yet.
But you can bet that ill be buying one as soon as 4k becomes mainstream

from what I read 4k doesn't go pass 60hz with hdmi 2.0 so the 240hz expensive ones are kind of pointless unless you are buying something than edge lit lcds

Upscaling 1080p to 4K in terms of noise reduction and detail enhancement will provide a noticeable difference from regular 1080P DEPENDING ON VIEW DISTANCE and TV size. Stated in this thread and elsewhere, even though you disagreed without any technical evidence in the other thread. We can probably ignore that first chart posted, but the CarltonBale chart is more realistic and accurate.

Speaking of which, does anyone know what the technical limitations are for broadcast and cable networks being able to put out content in 4k? I know networks now only show at either 1080i or 720p. Will we even be able to get 1080p (much less 4k) content over analog cable? Will I have to get a satellite dish?

By human standards? It's still odd to me, because the other charts are showing pixel perception -- e.g., 720P and higher all look the same to 20/20-vision human eyes when viewed on a 35-inch screen from 10 feet away. If that's the case, then increasing pixel density under those same size and distance constraints theoretically produces no change in pixel perception. The "imperceptible from reality" goal is far more complicated and involves many more improvements in display technology than pixel density.

Read about this a while back. Cable as we know it now won't be getting 4K broadcasts. By law, broadcast tv is limited to a signal of 19mbps max. That's not quite enough to broadcast true 1080P at full saturation. The law, infrastructure, and/or the way we receive "broadcast" television channels will have to change.

LG's 65" 4k OLED should be available soon. Wait and get that instead. Will be much better picture quality.
