I am looking to buy the Panasonic PT-AE4000U projector.
Panasonic PT-AE4000U (Panasonic PTAE4000U) Panasonic Projectors
Ideally, I would like to go for a projection screen size of 120 inches with aspect ratio 16:9. Room size is 22ft x 14ft = 264 in x 168 in. From Panasonic site, for a 120" image, throw distance could be anywhere between min 142" to max 283".
If screen size D = 120", length of room L = 22ft = 264", then 2D is 2 feet less than L. Many sites say thumb rule and recommended throw distance is 2D. That means, the projector will be placed almost at the other end of the room. The room will looks like this:
Screen of size D -----------------------L/2------------------------Projector(2D)----L
My questions are:
1. I expect people to start sitting from half way through the room, L/2 < seating < L.
That is, nearest person to screen is at L/2 = 132" in from screen and farthest will be at L. Will the image appear too big (like front bench in movie theater) or cause any viewing discomfort since most people will be seated within the 2D (recommended throw distance) and well ahead of the projector? In general, any formula for recommended distance for seating based on screen size?
2. Screen gain: Should I got for screens with gain greater than 1 or lesser than 1?
My dilemma is the room has 3 windows. Even with window screens, I expect some amount of light in day time. That makes me think going for gain > 1.0 is better. But I read that if gain < 1 then you get better contrast. So its a trade off between brightness and contrast. Which one to go for? Can you comment from your experience?
