I concur with Arrow's observations. This projector CAN put out a huge amount of noise if room temperature goes up. I've had to reactivate my cooling feed and ensure the room is up to temperature before running the projector to avoid the aircon dumping super heated air into the room and upsetting it. Once the film is running it tends to get lost in the background until the soundtracks goes quiet.Light output is poor - I measure ~1600 lumens @D65 from a 26' throw with iris wide open.BUT, it's also the best image I've seen so far in my room, and the constant brightness light source means no dimming, like bulbs, so I'll probably be keeping it. Need more viewing.
Screen size is 180" 2.35, screen research CP2 gain 0.86. Throw 26'. Lux measured at screen with CA183 and off screen with Klein K10A.
That may be true. I have a feeling this could be a reference projector for smaller screens. Kris's screen is higher gain and much smaller than the one you used. I'll bet he had the iris closed much more, so that the dynamic dimming doesn't work as hard. That said, it sure lit up a big screen at Cedia.
Based on the screen gain you gave, that is 2,000 lumens at your throw.
Bingo! That is precisely why we are recommending this projector for use with screens of circa 2.7 metres / 9 feet wide or less which is the size that allows you you make use of the various options that significantly positively influence image contrast such as closing down the iris... Where like I have said, this projector does produce a very nice looking image when it is NOT operating balls-to-the-wall maximum everything minimum contrast with no lumens headroom and (again speculating) negatively affecting the performance of the laser dynamic dimming... In other words, with the right application, namely 'sensible'/appropriate screen size in a low ambient light level room you can achieve a lovely looking image with this projector... But if you want high brightness and deep blacks on a giant sized screen then this projector is not the correct choice. This does beg the question, what is the demand for a $35,000 reference projector for small-to-medium sized screens? I honestly have no idea what is the answer to that question... Thoughts?
Everyone that is going to ISE, I would very much like it if we could have a schort (or long ;-) meeting(meaning a drink and a nice chat) in Amsterdam.I also think it would be good if at some point, we got together at the JVC booth, not to start a war but just to give som insight of what kind of remarks the different users like ourselves have.I know they are always been very informative an willing to cooperate with me in all those years as a client, i think everyone can benefit from giving as much info and user remarks as possible.And arrow still has to buy me a drink, so I will not take no for an answer ;-)
I am very happy I never even considered this projector, as it sound like a real flop from JVC that is not delivering even close to specs. I am very disappointed with this and at the same time I am happy I did not preorder and spent all that cash on a projector performing worse than the 1080p e-shift models (and then I am talking about my own HT)...A RS620 is most likely being ordered in a couple of weeks...
I have an X9500 on order now too Yeah this is kind of alarming regarding the Z1... IF this was actually shooting 3000lm in Rec709 near calibrated I don't think I would take as much issue, but it sounds like my incoming 9500 may be brighter in some circumstances, and have considerably more contrast, definitely giving up some sharpness, but that's a high cost indeed.
I am not giving up the contrast of the RS600/620 for a little sharper image and a lot more $, the RS4500 costs about 35000$ more than the RS620 in Norway...
