Rom is about 7'10 in height [basement] 92 diagonol screen, just trying to guess on mounting local so i can start running speaker wire etc before deywall. Is the eyes 1/3 up form bottum of screen a good rule of thumb? Any ideas apreciated.
start at 1/3 and tweak from there. for example, if you have recliners you might want to go higher since you'll be looking higher when reclined. also if you have a second row of seating on a riser you might want to go higher to reduce the riser height.
4805 with a stewert greywolf screen. about 12 feet back for pj, seating right about 13 feet, 7'10 ceiling. I have not yet worked out exact seating..i am finishing the basement, so i couldnt say exactly what i will be sitting on. What ever we find on sale at a furniture store
I also like having my eyes dead centered on the screen. I get one of those behind the eye headaches if I have to look up, even slightly, for a couple hours.
If you can, try projecting onto a wall, hang a sheet, or pick up some cheap "black out cloth" at a fabric store. It doesn't have to be perfect. Watch a movie, and decide where you like it best. 1/3 is the rule of thumb, but there are enough people that have alternate setups that I think it may be worth trying yourself before committing.
If that isn't an option, think about where you sit in the movie theater. In your typical stadium seating, where do you sit and where does that put your eyes relative to the screen? I personally think the lower the throw ratio (sitting close to a big screen), the more people will prefer to have their eyes centered.
Critical factor is the vertical offset. I was serious about an Optoma H27 until I discovered that it had over 50 degrees of offset. Since I am going to do ceiling mount, that would have put the bottom of the image near the floor. Check out this review because it has a good discussion. I am now split between an Optoma H31 and an InFocus SP4805.
