2d is good for us Mike. I guess I could go pretty short throw....rather not, but could
At short throw a 150" wide screen would get you around 19/20FL. That is with high lamp and iris full open. Low lamp would get you around 14/15FL. That is larger than I would go, but I am more conservative than this. At 12' wide you would be able to close the iris down some. You would also be able to run in low lamp for a while.

Yup sure seems that way. I'll wait for the 1/2 price deal no hurry.
Have you tried the steps I recommended of adding in the Denon while everything was powered-off then powering back up in sequence? Do you get a picture (make sure 'Deep Color' is OFF on the Samsung too!)?

I have the HDFury integrral, did not know it also boosted the signal. I would have purchased the Gigabit HDM-GA1 accelerator if I could have found one for $200 US, like I said, it is not out there now. Just got a price from the Canadian distributor Pioneer Canada

ARE YOU READY ?? Canadian price $850, so I ordered 4 of course . :rolleyes:
I haven't had one problem since I installed my HD Fury - also the best HDMI splitter I've used.

Back to the drawing board I guess...thanks Mike

Wow, this is actually really quite significant. It MIGHT go a ways toward explaining some stuff that seemed "strange" in my setup. Thanks for pointing this out.

I need to pay attention and see if it explains when I have been seeing. Previously I was pretty haphazard about whether to use Auto 2 or Fixed iris with HDR, because I was thinking there wouldn't be a significant difference (given how anemic the auto iris is).

I was attributing variation from disc to disc to the mastering of the content. But it could also be that I was something using auto iris and sometimes not.

Just a quick note regarding an HDR observation I have made in regards to the Iris setting on the JVC's. I don't remember reading about this behaviour, so here it is.

Although the Auto Iris is not supposed to work in HDR mode, if you have the projector in Auto Iris 2, the projectors iris is actually WIDE open no matter which manual Iris setting you had selected before switching on Auto 2.

I noticed this behaviour when setting clipping levels on the JVC, when I had the lamp on High mode, and set the Iris to -5 (Or any other setting for that matter) and I was in the JVC Menu, the iris was sure enough slightly closed at -5. Exit out of the menu (Iris set to MANUAL -5) and the peak white stays the same, iris stays slightly closed where it should be.

If you switch on Auto 2, then exit out of the JVC menu, the Iris will open fully. Hit JVC Menu button and Iris will close back down to -5 (Or whatever point you had set it).

To show this, I recorded a video. The JVC was displaying the Samsung 8500 Screensaver, the black screen with the Samsung logo floating around the screen. I then open and close the JVC Menu on the remote and you will see the Iris open and close. Closing when the JVC Menu comes up, and fully opening when I exit out of the menu. Which is actually the reverse of what you would see it do in SDR mode since the Sammy screensaver is almost a total black screen with only a logo floating around.

I then switch the Iris to manual mode and do the same, you will see the iris perfectly still, no change... I do this a few times in the video, Auto, Manual and then back to Auto again, each time I open and close the menu a few times...

Pretty odd!

So just a PSA. If you actually wish to set the Iris on anything other than fully open in your HDR modes, DO leave the Iris setting on Manual, dont switch it to Auto 2 thinking it may do something, well your right, it will raise your blacks and open right up!

Here is the video...

Presumably thats uncalibrated and brand new lamp Mike? I'd be surprised if you could hit 16FtL calibrated after a couple of hundred hours?
The problem with a screen that large is you miss out on the outstanding contrast you get when you close the iris down. Limit your screen size to 135" diagonal and maybe a 1.3 gain, and the picture is incredible, IMO.

Let me inject here too if you plan on running UHD/HDR I wouldn't go any larger then 110-120" or you will be disappointed with the results, especially if you are going to be over a 15' throw (assuming as you said you are going to stay w/ a unity gain material; AT or otherwise). ;)

Couldn't agree more Craig. I have the opposite problem - an AT screen with a negative gain (around 0.75). My screen is 110" wide (2.35:1) and I can no longer get 16FtL on high lamp and iris fully open (maxes out at 14.1FtL) now the lamp has aged.

I am hopefully going to secure a high gain screen soon to remedy the situation.

Hi All, Thinking about an x950r/rs600 as a place holder for a while until more 4k dlp/laser development occurs more affordably.....what is the largest non gain screen any of you are using them on successfully, light controlled?
I have an RS600 and a 126" diag. 16x9 Stewart SnoMatte 100. I have good brightness in 2D using low lamp and the iris open (Auto 2 mode). For 3D and UHD/HDR I use high lamp and iris open (Auto 2). I wouldn't be happy with the dimmer image of 3D or UHD/HDR if I had a significantly larger unity gain screen. For 2D I'd use high lamp if my screen was larger.

Right on Mike! :D:D

With your help, I have the Screen Innovations 160" 2.35:1 (equivalent 129" 16:9) screen, Solar White with 1.3 gain, with the less powerful RS400, and I am pretty damn impressed with the image: 2d and 3d!

Watched Despicable Me in 3D, and Edward Scissorhands in the last few days, and it was spectacular! Maybe I'd be even "more" blown away with the picture quality on a smaller screen, but where's the fun in that!!;)

Nope, haven't tried yet, have been at the cottage . Biked 70 Kilometers last night so wasn't up to the task when I got back. Tomorrow night maybe if the rain finally shows, been to bloody nice. :p

Well then, since I have two of these HD Fury devises will have to give that a go too . As I said, so much equipment , so little time. :eek:

One can run larger screens - especially if you are willing to change lamps more often. Maybe some day we will have laser projectors with contrast better then we have with todays JVC's, and 4000 lumens. Think of the big screens you could have then. A man can dream* !






* except I'm limited by my throw distance, so I'll hope and dream for the rest of you !! :)

Hi guys I will hopefully be joining you soon with an x9000 and a 145 inch majestic scope screen. Have been following this thread with interest and learning along the way. Hopefully will get a demo of one in Brisbane Australia soon and then go from there.Thanks for everyone's input so far.
