Were they using real 4k content, or up converted 1080p, I ask because when I was at NAB it was very noticeable, also saw the 8K broadcast demo and again it was very noticeable in the fine detail.

No. however, i remember people reporting back how bluray didnt look that much better than upscaled dvd. Its all down to perception. The biggest thing for me was the lack of blocky artefacts which plagued difficult scenes on dvd. HUGE difference to my home cinema experience. DVD could look nasty on a projector sometimes.

It stated that it was a 4K demo, they used a lot of upcoming SONY releases coming to cinemas. You could tell it was not a blu ray movie, however I wasn't blown away.

Well, it's a tall order to cause some viewers ‘to be blown away’, for I have many neighbors in my little area of heaven who are not blown away when watching DVD movies as compared to their Blu-ray equivalents...and don’t give a second thought as to what format to rent (rather than what is available on the shelf) at our local Blockbuster.

Plus, your review is a bit cursory. For example, how far away from the screen did you sit? What model TV was it? Was there a 1080p tv next to it, or close by, which was playing similar content but in HD? Etc.

Plus, we need to know how sensitive you are to differences in picture quality.
How about comparing the Blu-ray disc versions to these online streaming offers and then telling us what you think and your personal viewing conditions…

I saw the Sony VPL-VW1000 projector connected to the Sony server during a demo on a roughly 110 inch Stewart screen. It was easily the best projector I had seen to date. In addition the the usual Sony stuff they also had some footage from the timelapse movie Timescapes.

Well here is my untrained my .02 cents.

If you sat in the first row, then 4k source content on it was better than 1080p. It was also very revealing in that you could actually see some of the limitations of the cameras in which Timescapes was shot (digital noise for instance). Being that revealing of any fault in the source was actually the best thing for me to see in that demo, as it highlighted the strength of 4K at that image size. I put my nose almost against the screen, and you can't really see a pixel even then!

As far as up-scaled Blu-ray...good but not really any better at a normal viewing distance. maybe I need new glasses.

Could I justify spending twice the price or more compared to the current JVC DILA-RS65. Certainly not if your feeding it up-scaled Blu-Ray. Totally not blown away there. 4K source content will have to be what convinces me to make an upgrade. If they don't deliver something other than increased pixel density it just won't be compelling for me.

I really hope that we can move beyond what could be just the current Blu-Ray with more pixels. I would love to see 10 bit color, or REC 2020 or something beyond increased pixel density. It is cool but it is not the end of the road.

All this has convinced me that I am also going in to optometrist next week. I know my prescription is getting old.

Have Lawrence of Arabia been released on 4K yet?If so,anyone here seen it?

See THXGuru, now that’s ^ a more comprehensive review. Reminds me, for our 4K projector enthusiasts who would also like a chance to win a free 32GB XperiaTablet S or a HDR-AS10 Action Cam and live in the San Jose area (like my old friend Blu-ray.com member David Vaughn, whom I had no idea was a paint rep in real life and for which I need a consultation with regards to the value of semi-gloss versus flat paint for an exterior side of our house that is exposed to the sunlight for much of the day and invariably gets blistered due to the intense heat – david, I need your help!…is semi-gloss more protective?)

Anyway, for those other members so 4K-projector-inclined in the San Jose area, here’s a head-up to the above….http://whitlock.com/civicrm/event/info?reset=1&id=42

I’m trying to get out of the office early in order to beat the traffic and enjoy a long Memorial Day weekend, but when I get more time I’ll relate to you a story about how by looking closely at one of the test signals (description hyperlinked in this post…https://forum.blu-ray.com/showthread...ry#post7591928 )

encouraged a friend of mine to pursue an ophthalmologist’s appt., which resulted in them finding a retinal abnormality for which he went to surgery and gained improved vision , 20/10 in fact.

Long story short, when looking closely at the grid pattern test signal which can be seen on the Sony Blu-rays as described above, while covering one his eyes (to see if his prescription was ‘off’ with the left lens in his glasses), the lines appeared wavy – not straight.

Turned out he had developed a thin clear membrane (think like a small piece of cellophane wrap) covering the part of his retina that accounts for central vision which was causing distortion of the fovea of his retina (for central vision). He went under the knife and got that cellophane stripped off by an eye surgeon and Voilà ….normal vision in that eye.

The downside, waaay too much ambient light for critical viewing….

I have to say, saw the tv again today. I think it is one of the best tvs I have ever seen, simple reason is that the framing of the tv is flush with the television screen, the contrast/masking is outstanding.

The video processing engine (4K X–Reality PRO) for increased resolution aside, you weren't moved by the better colors?

Not unless it supports Rec.2020

If they were industrious, it wouldn’t be too difficult for a tech media site (like cnet, etc.) to do a controlled experiment comparing a Sony Triluminos display to a non-triluminos LCD (having no quantum dot technology whatsoever) and run a good variety of sample material through each, side-by-side, to prove or disprove the value of this color technology with real world broadcast and Blu-ray content.

I think consumers would much prefer reading something productive, like a shoot-out such as that, rather than the regular *2 cent analysis editorials* which are churned out from some of these tech journalists on a regular basis.

Well, Rec. 2020 is easier said than done ( https://forum.blu-ray.com/showthread...is#post7361160 )and what if some people are in the market now to purchase a new TV set (the kid is taking the family room TV to college in the fall, etc.) and are interested in the best color representation possible with their new, yet to be bought display….compared to other brands without quantum dot tech? Does Triluminos have comparative value?

Meanwhile, unbeknownst to most hobbyists and tech journalists, there has been development in production with a wider color gamut and higher dynamic range, the benefits of which will be used for some upcoming TV shows and at least one Blu-ray movie which comes to mind.

I’ve just got to hunt up some pdf’s as visual aids to explain the concepts. Also have to see if the Blu-ray has even been officially announced yet. No time right now. But yes, the ultimate would be a Rec. 2020 output device transform (ODT) for future TVs that may some day support Rec. 2020.

Same here Matt. I saw it at my local BB as well and feel the same as you do.

So, continuing, I’m referring to IIF-ACES workflow…
http://www.oscars.org/science-techno...ESOverview.pdf

which includes wider color, 16 bit half-float and standardized rendering…
http://www.hpaonline.com/assets/docu..._FinalDist.pdf

So, what does all this ^ mean to Blu-ray aficionados? Well, in a nutshell, it allows for improved scanning of a film source (e.g. old classics like Taxi Driver, new films like Lincoln, etc.) as defined by the Academy Printing Density and the Academy Density Exchange Encoding (see the linked presentation pdf’s above).

What about digitally shot movies for Blu-ray? Well, currently (without ACES workflow) when you shot with a digital camera that’s capable of recording wide dynamic range such as the F65, F55, Red Epic, etc., and proceed to post production, when you do a transform that converts the imagery to a limited color gamut space like Rec. 709 (for Blu-ray), you lose image quality (clipped highlights, etc.) in the conversion. But, ACES allows the post facility to maintain the full potential of the imagery within a workflow all the way to the finished output…currently Rec. 709 for HD deliverables.

So moving on, reports from early IIF-ACES workflow adopters seem very favorable if you read the comments by the DP and the colorist here - http://cinepostproduction.de/?cat=7&news=306 . In fact, outside of that linked press release, the digital colorist has also mentioned (in a professional working group) that only slight color and brightness adjustments were required to match all the different deliverables (film-out, DCP and TV) and they are so enthusiastic that cinepostproduction in Germany has set ACES as the default pipeline for all future projects.

Ergo, I’m looking forward to the Blu-ray Rubinrot - https://www.blu-ray.com/movies/Rubinrot-Blu-ray/71555/

a.k.a. Ruby Red - http://inkandpage.me/ruby-red-showin...-not-near-you/

Because all the above indicates (and things will only get better with future refinements), that without any heroic effort on the part of the mastering staff at the post house, the Blu-ray incarnation has the potential to look nearly identical (within the limitations of the technical parameters of Blu-ray) to the theatrical exhibition. This is a good thing! So keep an eye out for future motion pictures characterized by ACES digital intermediates in their cinematographic process.
