can the benq 2050a projector?

[markyboy156]

hi

can the benq 2050a projector
do 180 to 200 inches at 11feet throw distance that is the depth of my room and still have a fantastic picture without altering the brightness light ambience
is there anthing that can be altered to do this
thanks kindly marcus

and also i want to buy some sort of swing arm project bracket mount for it
which swing arm projector mount would you recommend

my room is 11 feet depth maximum
i have a room with a small open door section to my bedroom
to the right of my room which leads into the bedroom its not on centre for where i want the projector to hit the screen
i want to put the the projector to the very right end of the room of centre with a swing arm bracket that i asked for
so i can extend even further than the 11feet of space so i can put it further back into my bedroom to extend the depth even further
than 11 feet

can this be done

ie my room is 30 feet wide
the door to the right of my bedroom is to the very end of the room
normally i would place the projector in the middle of the room which is 15 feet to project the image on to the screen
but i will place the projector through the bedroom door at 30 feet using the projector swing arm bracket i asked for
will the benq 2050a be able to display the picture image of axis not cenred on the screen at 15feet in the middle of the room but instead at 30 feet to the right
if not is there anyway of altering the projector to the very right of the room where i will install it
even though the projector is completely of centre and still get the full 180 inch to 200 inch image quality and still get a fantastic picture

thank kindly marcus
can you reply asap

The short answer is no. Your projector doesn't have a lens capable of making such a large image at such a short throw distance.

For the purpose of a rough calculation, when the projector lens is set to give the biggest image at the shortest throw distance, then for every 1 ft of screen diagonal size, your need 1 ft of throw distance. Therefore, a 10ft diagonal needs 10ft of throw distance, 15ft diagonal = 15ft throw, 20ft diagonal, 20ft throw and so on and so on.

You want to have a 180" to 200" of diagonal image size. In feet, those screen diagonals are 15ft and 16ft 8". In rough figures, you would need 15ft of throw distance from the lens to the screen to make a 180" diagonal image. One other issue you may run in to is the height of the image. A 180" diagonal 16:9 image is about 8.5ft tall. If you live in a British home built in the 1950s or later, then there's a good chance that the image will be taller than the room height. That means it will spill on to the floor, or the ceiling, or both.

I think you were also talking about trying to get the projector offset to the side. There are two ways of doing this. There is electronic keystone correction, or there's horizontal lens shift.

Your projector doesn't appear to have horizontal lens shift, just the vertical control. It does have electronic keystone, but that will distort the image and has the effect of making the picture smaller the more it is applied.

Finally, image brightness and quality always always drop off when the picture is made bigger.
