Layout\furniture advice for projector setup 2.5m x 4.5m room...

[robo989]

(First of all sorry for the crosspost, wasn't really sure where to put it, as its kinda projector related and need projector knowledge (maybe) but is more furniture releated - mods hope I haven't been a pain and feel free to delete either if you think one is inappropriate, thanks and sorry)

Righty there, I'm moving into a new flat tomorrow or saturday. I got one room spare that is going to double up as a spare bedroom. The dimensions are...

4.5m x 2.5m (With a window on the end), it looks like this....

_____________

W
__________D__

W = Window (Quite wide)
D = Door
(The gaps at the ends are walles still, can't seem to get them to appear right on the forum)


Now, me projector (A DLP Yamaha AX-830) is coming tomorrow and I'm off to IKEA in the afternoon and was looking for some advice in furniture to buy, and where to place the projector etc...

I'm abit stuck as obviously the screen can't pull down over a window right? On the other side of the room would be ideal near the door, wouldn't it? But I can't mount anything to the ceiling (walls are fine)....So where would the projector go? Can't really have a shelf in the middle of the room?

Then I thought maybe do it width ways? But would that leave everthing abit squashed, and is a 2.5m "throw" too short?

I'm hoping to have a screen about 85-100 inches wide and get the boys round for a smoke and a few beers etc so would like it luking nice...

Basically would really like some advice on...

Location of projector & screen including height of both
Ideal furniture to get that is comfy

Thank you so much for any help with this
