WOW,yet another format!. I just went from s-dvd to blu-ray and 4k? Can wee stay with one format! same for computer gaming,new game comes out,i have to upgrade. Sick of playing this upgrade game!!

4K is light years away for home theater. Most digital cinemas today use only 2K. You would have a difficult time telling the difference between 1080p and 4K on a 65" screen.

Mike, the upgrade game is a never-ending process, so you might as well get used to it. Still, as Ryan points out, 4K is years away, so there's no need to worry about it just yet. To Ryan's other point, seeing the difference between 1080p and 4K on a 65" screen depends on how close you are. I've seen 4K on such a screen that looked amazing, obviously better than 1080p, but that was from a few feet away.

Scott to expand on your point. Is there a screen size, in your opinion, that is so large that that even 1080p sourced material begins to lose its image quality. In particular, I'm thinking about front projector screens sizes.As you pointed out, distance from the screen is important but I would imagine there is a case where you would need to go so far back that it is unreasonable.

To David P.: Roku offers TWiT, as well as the services Scott mentioned, Hulu Plus, Revision3, MLB TV and a wide array of other services, and adds new services all the time. Considering that Roku boxes are only $60-$100, it's an easy way to expand on whatever web offerings your TV or Blu-ray player has.

Ryan, the screen size at which 1080p begins to lose its image quality is mighty big. Most commercial digital cinemas have a resolution of 2K (2048x1080), which is very close to 1920x1080, and they use much larger screens than just about any home theater. Sitting at a normal distance from those screens, the image looks very good to me. Now, I never sit in the first few rows of such a theater, but I'm sure I'd be able to see the pixel structure in that case, whereas I might not see the pixels in a 4K image under the same conditions.A couple of years ago, I had the opportunity to see a split screen with 2K on one side and 4K on the other on a very large commercial screen, and I was able to walk right up to the screen. With my nose nearly touching the screen, I could see the pixel structure on both sides, but obviously, the 4K pixels were much smaller.

While I agree that 4K won't be viable for several years if at all for the home, I disagree with the statements about Panasonic. The Kuro's were Panasonic Professional Panels with Pioneer power supplies and GUI's. If you want a Kuro picture look to the Panasonic Professional series. Which incidentally doesn't crush the deepest blacks as the Kuro's did.

Robert, I've never heard anything from my technical contacts at Panasonic and Pioneer that corroborates your statements, but I'll try to verify this specifically. And my Kuro certainly does not crush the deepest blacks, so I'm not sure what you're talking about there.

Isn't Ramon still not going to see a high-def picture if he upgrades his TV but uses his AVR component out? Doesn't HDCP prevent a full high def signal from going out any other way but HDMI?

Matt, component-video will convey 1080i, but not 1080p for the reason you cite. So Ramon will see HD with a new TV.

4K is not years away. JVC Pro makes them and Meridian re-badge them. I had the oportunity to see one in action on a 20FT wide screen with a 1080P BD as a source, upconverted to 4K and it was the best presentation I've ever seen. The real benefit however is on a very large screen.

Robert, according to the former plasma guru at Pioneer, you are not correct. He has watched Kuros, up to and including the last generation, being manufactured in Pioneer factories. Also, he says that if you see crushed blacks on a Kuro, try turning down the room lights.Enrique, yes, JVC and Meridian make 4K projectors, as does Sony, but they are hundreds of thousands of dollars, so I'd hardly call them mainstream. I still maintain that mainstream 4K is years away. And yes, 1080p upconverted to 4K looks great, but not as good as native 4K content, which is also years away from being mainstream. Finally, you are correct that the real benefit of 4K is on a very large screen.
