Nice!  Did you buy one, Mike?    Craig Peer did, didn't he?

Can't really buy one until they exist.

Can't really buy one until they exist. 

I thought you pre-ordered one for yourself?  Anyway, here they come!  I'd be interested in a comparison between it and the current RS-500/600.

Still hope I can do that. Maybe I will know more after tomorrow !

Keep us updated. I want all the nitty gritty details.

[AVSCraig]

You'll get them here - Friday. I'm sure I'll be too tired when I get home tomorrow.

Kris do you have a computer that can output a 4K signal?  If not I might be able to bring something over.  I know that most people here probably don't use their HT as a computer screen (I DO!) but I find it to be the ultimate torture test for sharpness and uniformity.

Not sure if mine does or not, my laptop has a 4K screen though. Where are you located?

[Kris Deering]

Are you sure you are in low lamp ? I can't close the iris down that far and still have 16 - 17 foot lamberts, except maybe in high lamp. But black levels sure look good. I'm interested to see what dynamic laser dimming brings to the party !

Definitely in low lamp!

JVC DLA-RS4500 - Questions asked at CES today -

1.  How much lag in gaming mode?  2 frames  ( under 40ms )

2.  What features are disabled in gaming mode? None other than keystone

3. Lumen output without DCI filter? 3000 lumens before calibration

4.  Lumen output with DCI filter? Wait for Kris Deering’s Sound and Vision magazine review.

5.  Native contrast? JVC is not publishing native contrast. Wait for Kris Deering’s Sound and Vision magazine review.

6.  Auto calibration? If so, what meters? Same as the RS400 / 500 / 600 series. JVC sees this projector as being more suitable for a professional calibration.

7.  Noise level? 25 db in low power ( about 4 db more than an RS500 / 600 in low lamp ). It sounded pretty quiet to me in high brightness, personally. 

8.  Any type of dynamic dimming with HDR? Yes – using the laser.

9.  Ship date to dealers? End of Jan.

The RS4500 was being shown on a 10' wide 16:9 StudioTek 130 G3 screen, and HDR looked pretty damn good. The ansi contrast is higher on this projector than current JVC's, and it really had amazing depth of field and a crisp look to the picture.    Now I'm going to bed.

[Kris Deering]

Wow, no pressure on me huh???

Wow, no pressure on me huh???

well you wanna be a big deal....lol

[AVSCraig]

Wow, no pressure on me huh???

We love you, you are the man. And we listen to the man. 

Seriously, they just want a reputable reviewer to state the facts. Ansi contrast is supposed to be much higher on this projector. They had the THX certified unit at CES, and the 4K Blu Ray " Warcraft " they were playing looked really crisp, clear, and had great depth of field. Actual native contrast was impossible to judge in that flawed Venetian suite, with a movie I've never seen with HDR ( which raises black levels to begin with as far as I've experienced ).

[AVSMike]

The screen size at CES was limited to 10' wide, not because of the projector, but because the freight elevator is only so large. In other words JVC could not fit a 12' wide screen into the elevator.
