ifa?

 

you thinking jvc is doing an 8k machine. possible I guess as thats what the nhk device was for 8k for them, though that was using e-shift :)

 

do wonder what jvc brings this year. though to be honest pretty happy with things. though I do tend to turn over every 3 plus years :D

 Kris Deering is the only person who claims to be a reviewer has that opinion  in relation to Sony,  not just in North America but Germany as well.

Thats not the case at all, the issues Kris are I are talking about are well documented on AVS Forum.

Deering doesn't use any of the electronic contrast enhancements Sony has built in to the PJ  ( which are based on the 5000 electronics) - and this could  partially explain the difference of opinion.

The problems that Kris is concerned about, namely a total failure to resolve a 4K test pattern and poor screen uniformity and discolouration when displaying test patterns are due to the zone convergance correction system Sony insists on using.

While they are extreme tests and not really relevant to real world viewing the uniformity-discolouration problem does show up in real word content occasionally, and if you know what to look for is going to be a source of aggravation.

Contrast enhancement systems like Reality Creation don't help all with these problems.

In a perfect world, faced with overwhelming dissenting opinion , an objective approach  would be to investigate why the perceptions are different  to  see if the results could be replicated.   But based on the language used, it  just looks like fanboy stuff. 

Kris IS taking an objective and repeatable approach to his testing, NOT the fanboy swallow the manufacturers BS approach that so many others, including reviewers take. Anyone can verify and confirm his results, just display some 4K test patterns and you will see to.

On second thought, maybe its better people don't do that as the results could play on their mind and affect the enjoyment of their new toy.

Deering is having a direct shot at Sony owners for being satisfied with its  performance  in the light of the objective data. 

Objective tests show there are problems with the 4K Sony that obviously many owners don't notice or are not concerned about because overall they are happy. Even Sony is betting on owners not noticing so its no surprise most don't.

How is Kris having a shot at anyone by pointing out problems????? Its his job to do that and if owners get upset thats their problem not his.

You can turn off the factory panel alignment in all of 5 minutes on the Sony and get perfect 4k test pattern results. For some reason you apparently need RC on to have it be particularly sharp though. But at least you can be rid of all the moire and discolouration effects.

True, BUT the consumer should not have to go into the service menu and potentially void their warranty to turn convergence correction off. It and digital sharpening should be disable-able in the user menu, but Sony obviously don't want people to do that for obvious reasons. With the convergence system disabled consumers are going to find out that native convergance will often be quite poor and want something done about it, and with Reality Creation really turned off (rather than off in the user menu) image sharpness will take a dive and consumers will find out that they have been taken for a ride.

The fact that digital sharpening is so effective at compensating for a lack of native sharpness due to convergence correction, lens quality, video quality etc is very telling. It doesn't increase resolution but sure does fool people into believing there is much more resolution then there actually is.

Sonys Reality Creation is not the only game in town either, PC based video processing is at least as good, if not better, and can be used with any projector. This opens up the option of having a nice clean, clear and sharp picture with much better contrast and lower black level than Sony offers. 😉

 

Just to clarify, the only way to align the 3 LCoS panels in the projector is to physically move them in the light engine, and that can't be done outside the factory. The so called "convergence" adjustments don't actually converge anything because like all digital projectors the Sony is a fixed pixel display and the pixels can't be moved electronically. All the system can do is use 2 or more pixels to do the job of one, which results in a drastic loss of resolution as well as discolouration and moire. Its fortunate that the loss of resolution wont be noticeable because resolution beyond a certain level is just not important for reasons I have discussed, and the discolouration-moire will very rarely be an issue with real world movie content.

 

Paying extra for "true 4K" and not getting it is one thing, but Sony deliberately lowering resolution to hide convergence problems and at the same time creating further problems by doing so adds insult to injury IMHO. Consumers are being rorted and there needs to be a big fuss made over it to give Sony a good kick in the butt.

 

Its time for consumers to WAKE UP and realise that "true 4K" is NOT the big deal people think it is and 4K visible resolution movies don't exist.
