Thanks for the comments guy's. My room is 13'8"x24' the ceiling is 8 1/2' it was a 7 ft drop ceiling before the remodel. My screen is 110 diag paint Bright white (eggshell)hardness, the center speaker sits on the 24" high stage the screen is 33" off the floor. The screen drops into a screen pocket 10" deep in the wall(this was done to control ambient light reflection) The bulk heads above the screen are 15" wide this gives a 25" bulk head over the screen and is painted the rooms dark burgundy(this helps control light reflected light off the screen itself) what light that does make it to the white ceiling is being asorbed by the dark wall,carpet,curtains and dark chairs.
Seating head distance from screen 9' and 14' (just measured) with 3ft between rows. The platform is 10" high and sets off the floor on 2x6 runners the rope lights are under the platform,it's a 2x6 on 16" centers 1/2 ply to with pink wall insulation in the joist. It has a oak around the outside . Since if rest on/above the carpet it slides for adjustments(not real easy mine you) it weight a few hundred pounds and is vary quite when stepped on.
Lighting 9 zones still need to compete the last zone, I use dimmers on all zones and used non glare glass on the posters(must keep reflections under control. Also all lights have colored shades/thick milk glass or moveable eye balls to direct it by from the screen. Colored glass/light is a great way to add some light to a room (for a cozy feeling) and has a much smaller effect on the screen than white ambient light.
Three biggest factors(I feel) that effect picture quality the most, in a front projection system are ROOM COLOR .....ROOM DESIGN....and how both these effect AMBIENT LIGHT.
Most people think the quality of the picture comes from what BRAND pj DLP/LCd or Players,cables screen ect..............and yes they all have an effect on picture quality but it is small % in comparison to the above 3 rules.
I personally think the key to picture quality is work the whole room around the screen design(not the color or type of screen that helps some also)but how to drop the screen out of the room. I used the wall pocket trick, behind stage curtains is slightly better(if done right) and dropping the screen back into a whole cabinet wall unit is another. I saw this little trick at my local HT professional store and it was beautiful the screen was 18" back from the from of the oak cabinets,they had lights inside the glass doors and can lights above the seating area with narrowed focused spot bulbs aimed straight down, their room had twice the light I use and still had the same bright picture.
The only down side to cabinets they cost more than my whole room and that includes the equipment!!!!!!!!!
If I ever do it again I will drop my next screen 18" behind stage curtains, with a curtain baffle in the middle, of course the depth of drop depends on the seating angle.
and keep asking question this site is great place for learning info of design, I learned a lot out hear (seriously)......well ok 10 years as a new home contractor,and 30 years of remodel experience helped some to. Last I did all the Labor in my room except for the dry wall mudding(I hate to Mud) and the Mexican crew I hired did it so inexpensive I did not even argue the fact I had to finish sand for 20 hours to bring it up to my standards.
