Jim what is your throw? I have a 18 ft. throw on a high power 2.8 Da-lite screen at 144 inches. for a older projector.

why is there 3 model numbers for the same projector? Is one for Europe?

Thanks to all for there input.
Lastly, would a Darbee benifit the RS48?

Seems a really supid question to me, as the RS48 should be outstaninding, period. But, everyone online who runs a PJ, seems to swear by it...(?)

YES/NO - And your findings ?

Yes, Darbee works well with most displays, even the e-shift JVC's. I normally run at 40-50 with my JVC X90 and e-shift enabled but last night I had to drop it to 20 as it was a particularly grainy film and didn't look so good with the Darbee at the higher settings. For most content though, I normally have it 40-50 and just leave it there and seldom change it.

For all it costs, its not even 10% of the cost of the projector but it has a very welcome improvement to the picture.

And yes, the RS48 should be outstanding on its own but so is a Porsche Carerra. But why drive a Porsche Carerra when you can upgrade it to a Porsche Carerra Turbo for very little extra cost smile.gif

Thanks for the input on your screen size- would that I could fit 148. I've fiddled around with the JVC and projector central calculators and am gaining confidence that I could run a 134" diagonal. If I've done my homework correctly, the minimum throw for 134" is 14.01' screen to lens. That would put the projector in the aisle between the first and second rows. Moving the throw back to 20' would put the projector above/ slightly behind the second row. This seems quite doable since the max throw is 28.52'... is my logic correct on this?

My throw is a little more then 16'. The 3 models are the consumer (X55), commercial (RS48) & professional (RS4810) grades. They are all are the same basic projector but the RS4810 comes with a 3 year warranty vs. 2 & it said to be inspected by JVC for proper performance before shipment. wink.gif

I'm running x55 with 134 inch screen with the projector 17 feet from screen with no issues.

I think I am going to move forward with a 134. Having a target screen size goes a long way to getting a room plan together.
One more question- does the lens need to be located within the screen vertically to use the zoom method for CIH? Poking around I have found some posts that indicate it does, some others indicate you can locate the lens above the top of the screen.

I watched a video on youtube from Art, showing eshift2 switching from on and off and to me eshift2 seemed to give the same effect a darbee does with a standard 1080p projector

e-shift and the darbee are quite different from one another. a Darbee will not turn an RS46 into the 4810.

This is difficult to photograph, but this gives a basic idea of the difference.

If you are talking 134" wide, then you can locate the center of the lens 17" above the screen. This is assuming no horizontal lens shift is used. You never want to use all of the lens shift. Try to place the lens near or a few inches above the top of the image.

As Zombie said, the Darbee is very different from E-shift. The Darbee is a great addition to your projector.

Hey Guys,

 

I have a JVC DLA-X55R on order along with a Stewart Studiotek 123" 16x9 1.3 gain screen. The top of the screen will come down about 21" from the ceiling. The projector will be about 17.5 feet from the screen and this is a dedicated theater space with total light control.

 

1) What is my vertical range for mounting the projector from the ceiling? My soffit comes down about 12" and I was wondering if I could keep it hidden in the soffit or does the lens have to be even with the top of the screen for optimal performance.

 

2) If it is not lined up with the edge of the screen, will I have to deal with pincushion or other issues?

 

3) Will a 1.3 gain screen make the image too bright? I will mostly watch movies with little to no light in the theater. I plan on running on low lamp mode to keep the bulb life longer and the fan sound down.

 

Thanks in advance.
