I think after calibration the RZ470 will be a good 1080p HT projector.
anyways its going to be a good alternative HT lamp-less, if someone eager to have one ( IMHO ) biggrin.gif

we are all waiting Kraine for this review - and i can read between the lines its not that disappointing but i doubt 3D tongue.gif

No doubt its going to be better then K750 or PRO9000 wink.gif

THANKS

hi yy484 smile.gif

First a funny thing, the projector is 3D ready with DLP-LINK and also Vesa-3D and it is possible to make the two work simultaneously! This is the first time I see this and the 3D is excellent!

I'm guessing the 370 will be the same as the 470 except no 3D and lower contrast?

Will be interested in calibrated lumen output

biggest interests......

1. Native contrast/and black level performance in best mode/calibrated (and...will it calibrate to a decent and even 6500)
2. Lumen output in best mode
3. Rainbows!?!?!? (yes, they are still possible)

4. Sharpness. Infinite focal length is a very interesting topic.

Yeah, those lumen numbers are profoundly disappointing.

The native contrast is better than what I was expecting. Even without a DI, it should look pretty good with most bluray content.

So is this done by dynamically dimming the LED's? Isn't that kind of useless contrast unless the entire screen is black? Kind of like edge-lit LED TVs?

I wouldn't call that native contrast.

eek.gif was not expecting that low lumen numbers. I'm not sure if the other person that said around 1500 lumens in the other thread was correct but, I don't think it was calibrated to D65 anyway. Kraine, I know you like the Sony 50es. How does the brightness of the Sony and this projector compare on the same screen? People have said the led/laser projectors appear brighter than the numbers suggest.

Tom the HW50ES is much brighter almost twice as the RZ470.

Wizziwig the contrast values are for native contrast.

Native contrast and brightness at 6500 is not bad at all, considering the newish technology. Put this thing on a high power screen and there's no problem there. There's 10,000 dollar projectors that are LED and are barely that bright.

Definitely a step in the right direction IMHO.

I believe that is the case only if the laser is fired directly at the screen; here it is simply a light source and the display panel is imaged on the screen in the normal manner.

True, not native, but only useless if there's part of the image that's 100 IRE.

If less, the blacks can be lowered with no brightness penalty.

Just like a dynamic Iris. Nothing native about that.

Exactly the point I was trying to make. I guess LED dimming can be faster than a dynamic iris but that's not always a good thing if it causes noticeable pumping/changes to black level. Needs to be tested with difficult content like credits of white text on black background fading in/out or scrolling.

So what are the prospects for this sucker replacing my Sharp 80" LED TV? I'm sitting on a High Power screen and with no concern for conserving a projector bulb, then...?

So it is impossible to correct gammut and colourspace? Semms like the LEDs do not have a favorable light spectrum and because it is single chip DLP there is no way to correct this with colour filters an retain a usable amount of light (like Mits and JVC do since they only filter green light).
