4K Blu-ray discs arriving in 2015 to fight streaming media [CNET]

Yes, I'm still the kind of sucker to buy into a new physical format. I'll need one more 1080P TV to get me by until 4K is more entrenched, and hopefully by then projectors and Dolby Atmos receivers will be where I want them for a major HT overhaul. Yes, I probably need a second income, because I keep wanting to buy more from Axiom, too.

I'm just going to buy two 1080P tvs and watch them at the same time to make 4K.

I heard on the radio yesterday that there is now an 8K TV being demoed - LG I believe. Where will it end? There has to be a point of diminishing returns where there is no point in going any farther.

Even with my new eyes, looking at TVs in a store I see no appreciable difference between HD & 4K at normal viewing distances; however, large projectors would be a different story...

I would agree. Unless one is getting in to very large screens, especially for commercial applications, I am not sure what the point is here.

I'm more excited by the wider color gamut than the increased resolution, but I still want that, too. Beyond 4K would be a pretty hard sell, though.

What is going to happen is that the cost of buying the blu-ray is just going to shoot up as they say you are getting more so you need to pay more.

The cost of pressing a blu-ray vs a DVD is acutally less as the media price is identical, but DVD requires that all the information be re-mastered down to a lower res and the sound be re-encoded down to fit in the space limitations. Yet they charge a $5-15 more premium for blu-ray just because they say it's better.

Sorry, I will refuse to buy it.

Somewhat unrelated, but I just bought a 16X blu-ray burner for the new computer I'm building. The price for the 25gig blu-ray discs seem reasonable, but not for the 3 or 4-by layered ones ( BDXL) that hold somewhere around 128 gig (according to what I read). They want $40 some bucks per blank disc for those. That seems outrageous.

I sit about 12' away from a screen that's 96" wide when I have it in 2.35 mode. Just last night I was watching a blue ray movie and just amazed at the clarity and wonderful color. I'm a sucker for video gear, and always looking to "upgrade", but I am just not buying this 4K tech. I think a person would be better off investing in video calibration equipment and the gear that enables you to get the color gamut and grey scale dialed in. I can say with absolute, and undeniable certainty, that if either grey scale or gamut is out in the weeds, the picture will look like crap. Dial these in and the image will pop and look fantastic with 1080P. Now if you happen to like a REALLY big picture, like 2/1 distance / size ratio, 4K might be for you. But I don't know about that either, because I can get up to about five feet from my screen and the image still looks terrific. Lumagen has a device they call the Radiance Mini. I'd suggest anyone invest in this box a good meter and Chromapure. You can get a bundled package from Chromapure that includes your choice of a Radiance, a meter and the software. I'd give this a try before dumping a ton of money into a new display, new AVR, new cables, etc....

The auto-calibrate function ChromaPure has works amazingly well, even with 3D. I just set the meter up, hit the button and take a nap. 30 minutes later, it's done.

We rarely see from Movies or TV shows a person in a striped shirt with very tight spacing on the stripes. When I have seen such things shot in HD it has a weird wavy effect. I wonder if going to 4k would solve such a problem. Also, I am sure there are other such issues, that many of us laymen are not aware of either.

Of course, I am not saying we need to replace our 2k sets with 4k just to handle these small issues. But, it is likely when we go to buy a projector or tv in about 2 or 3 years, 4k is going to be the only choice. I am excited at the possibility of getting better performance for not really much of an increased price since I do plan to hopefully buy a projector in 2-4 years.

So if i get this right, the hardware box is connected to and sits between a DVDp and the display unit (let's say a LED TV), then runs patterns from the DVDP to the TV for calibration. Images are picked up by the meter, the software analyzes and changes colour, gamma, etc. updating its own hardware box, which then translates to a calibrated signal/visual regardless of what visual settings the TV has?
Or is this solely for projectors only? (though i can see how it might work with a TV as well no?)

The info on their website is rather poorly presented and not particularly clear on their products, requirements, setups...
