Well folks, I just plugged in my RS4810 for the first time and HOLY MOTHER OF GOD!!
This is my first PJ. I don't have a screen yet but I am projecting on a 120" Diagonal 2:35:1 white board. This is in my living room and I tried samples of BD 1.4, STK 130 and Firehawk G3.
STK 130 is what I will order. The BD 1.4 is not a good choice for night time viewing and if you plan to sit even 1 sit on the side of the sweet spot. Same for the Firehawk. They help blacks a bit but they crush the whites and colors so much that is not a fair trade. At lease not for me. Also, seating just 1 seat on the side or laying down on a sofa will make the pic much much dimmer.
After 6 months of researching screens and PJs, this was the best way to get a feel for this size screen for my living room. The black levels in this projector even in a living room with white ceiling make gray screens useless. I can totally live with the black levels on a white screen, especially a STK 130.
I will post a picture tomorrow. I'm extremely impressed.
I would like to thank Mike Garrett for helping me with over 100 e-mail thread questions and the purchase of this amazing projector. He is extremely helpful and will have my business from now on.
