Concern over 4k and replacing

[bobbydrugar]

Also just a PS. He also mentioned in the e-mail chain that the set had not been calibrated yet so there may be more differences especially once the color gamut is configured properly as 4K has a wider color pallet and can in theory more accurately reproduce more colors.

The bottom line is, we can only know once we set it up in our home cinema. I can't take too much notice of second hand accounts/opinions.

Isn't that actually how most knowledge is spread though. Reviews, experience and word of mouth. I would think it kind of silly to make all judgments based on having to purchase everything so I could see it myself. at some point you need to be open to the possibility that other people may have valuable information that can help in making a decision.

Yes,but if I had listened to some I wouldn't have upgraded to bluray in the first place. My experience was wow. Some people said they couldn't see any difference between bluray and dvd. That fact simply stunned me. So, my experience was a world away from what was being said and written by some.

Here's a link to his review: http://www.amazon.com/review/RJF77O1...x17O64ZYVIN3OL

I'll be checking his next update to it after he finishes the cal. Obviously, if someone has a question you can leave a comment for him. He responds in a matter of minutes.

My last exchange with him. He doesn't think he's an early adopter.


"You are more of a risk taker than I am. An Early Adopter. Many people will wait around to see what the BDA comes up with for a 4K disc specification. I will probably start upgrading to 4K with a purchase of a PS4 which will have access to the 4K download service.

Once you have completed your calibration perhaps you could compare a standard BD with a 4K download, assuming you have the same movie on your 4K media player and on BD. I would be very interested in your comparison, particularly of the color palette. I watched the 4K demo running on the Sony at my local best Buy. I was impressed, but didn't have any direct comparison.

You can bet that there are many people reading your review and following your comments."

Matthew J. Liptak says:

I have to disagree there. I agree I early adopted this set however, I did very careful research on several sites and had several in store demos at Best Buy. I contacted Sony a dozen times to discuss with tech specialists, many of which were not even up to speed with 4K. I tend to adopt what Sony adopts however since they were the first to choose Blu Ray with PS3 systems. Sony knows what they are doing and I was looking to upgrade to a 65" anyway so why not go with the latest and greatest image. The tech comes at 10am tomorrow and I will be sure to keep you up to date. From what he says, he will make this pop and I will see a clear difference in color and grey scale and blacks etc. I am not regretting spending the extra amount on this set since this is a definite improvement over regular HD. I am also purchasing the Sony PS4 and with the side by side game play allowed on this set, it will be awesome!

(edit) Liptak updated his review after calibration was completed:

"UPDATE 10/10: I had the Set calibrated today by a 20+ year Professional Calibration technician with some high speed calibration equipment. Adjusted Grey Scale, black levels, color etc. What a difference. Sony was not off with factory settings he mentioned, however he adjusted to Custom Settings and adjusted all sorts of levels including Gamma and it is unbelievable. Everything is in natural tone like it should be and now this set is even more magnificent. This now looks like it should and the 4K really pops! Awesome!"

I'd love to know what colour space/bit depth/subsampling Sony are employing on their 4K downloads.

It is Rec. 709, H.264, 8 bit, 4:2:0. Rec. 2020 (for UHD) requires 10 or 12 bit.

Now, the company has launched its second-generation of that technology with a new StudioRes option that'll stuff 4k, 10-bit, 4:2:2 video onto the latest UltraHD screens like Sony's $25k 84-inch XBR model.

• eyeIO StudioRes. Built to Hollywood's 4K requirements, eyeIO StudioRes delivers UltraHD, studio-grade H.264 videos (10 bit, 4:2:2 video, xvYCC). eyeIO StudioRes is available for both package media and Internet streaming delivery to bring no-compromise pictures to the next generation of 85" and larger UltraHD/4K screens.

eyeIO also claims its software creates StudioRes and existing HDRes H.264 files 45 percent zippier now, while using 26 percent less bandwidth for "super-fast playback and even clearer, crisper images" in both 2D and 3D on TVs, computers and mobile devices. The company also announced the forthcoming eyeOS UNIX OS for enterprise level 4k video coming next Spring, along with support for the upcoming H.265 standard through its eyeIO.265 product
