after more than a year delay i have the unit at my cinema
since last friday.
you see the dealer is very happy that we have no "accident".
i was surprised how easy it was to bring this huge monster down to the theater.
its about 125 kg with the lens so almost 3 times the qualia and its much bigger see the pictures.
one problem the unit have is the limit inputs.
you can feed 4 k at the moment only by order 4 hd sdi input cards and a computer that handle the this inputs.
than i need (because all consumer source is dvi or hdmi)4 converter dvi to hd sdi and there is no legal
way to send material with hdcp to the pr
sony is working on a dvi input card but seams with no hdcp and you also need 4 inputs then.
you only do not need the 4 converter and you can safe may $20000 for the converters.
i decide to use in the first steep the unit only at 1920x1080 feed by the new vigatec scaler s1 output it as a
dvi signal to a folsom image pro hd converter to get hd sdi.
very sad i only can playback material that was not copy protect but i have a lot of very very good material in hd.
4k material will be anyway not out for consumers anytime soon.
i used a prototype from the first pace stb in europe with mpeg 4 hd 1920x1080 50i and d theater and i also
have a hd cam from sony with almost uncompressed hd reference material at 24p 25p with a direct hd sdi out to the
in theory when the 4k pr
.scale a 1920x1080 picture to 3840x2160 in a good quality i expect (like if you scale up dvd from 480i to 1920x1080i) a picture improvement.
sad this was almost not the case.i cant see a big improvement may i very little one.
i thought that the unit is not good in cr. but surprised it was very good.
i measured about 2000:1 cr. an this with full light with one lamp.
it looks very good better than my qualia that i run with no iris in high lamp mode at about 1250:1.
the gamma trick that sony do with all there high end units since the qualia is out helps a lot to rate the cr. much better than the
because my power supply is not strong enough i use just one from two 2000 w xenon lamps and i get at 4 hours lamp runnig time 6000 ansi
runnig 2 lamps should offer 12000 ansi when the lamp is new and thats about 20% more than the sony spec.
so you can get high light out with high cr. at the same time.
remember the qualia offers at iris 2 at 2000:1 only about 600 lumens so the 4k is about 20 times brighter and
the smaller unit about 10 times.
convergence is not good.
there is the complete red shift 2 pixels down over the complete screen see the pictures.
i dont know but it should be possible to adjust it because what sony need to do is just move the red panel up 2 pixels
and that safe most convergence bugs.
as bad as it sounds and look in the picture it was surprising almost not visible!
i can live with 2 pixels of when the unit is ok in the center and at the corners you have 2 pixels but not with the bug in the center of the screen.
remember if the 4k have 2 pixel of that the same as a 2k pr
. have 1 pixel of.
btw:sony spec. is 2 pixel but as i sad i cant live with it if the center is also 2 pixels of.
mr. schmitt and mr.lange from www.cine4home
was also there to measure the unit.
they found that the color is very good factory calibrated to d 65.(you will see in the next few days a longer report about the test at his page)
so make it not to long i have to say that with good 2k material the unit offer the best picture i ever saw.
very bright very good cr. very good colors almost no shading no bright corners no halos no false countur bug no dittering........
the negative sides are the convergenzproblems and the inputs without hdcp and that you always need 4
input boards to feed true 4k content.
the unit need a separate room because is much to big and much to noisy to keep it at the same room.
i can simulate how good a true 4k image will look by selecting the 4 screen mode.
see the picture.
i use the robbie williams concert clip "let me entertain you" from hd cam and that material blow us away.
on a big screen you will see very easy the 2k to 4k difference and this makes it clear for me the future is 8 mil. pixel not 2 mil.pixel.
from the 1.5 times the screen wide we are sitting the 8 mil. pixels are above the human eye resolution.
beside jvc i see no competitor in the next time with a 4k pr
if sony can fix the convergence and offer a dvi input card with hdcp (with at least 1920x1080)i may consider a purchase the
smaller 105 unit with 5000 ansi.
more pictures will be add soon.
