You'll be fine at 120 scope zoomed. I have a 140 scope zoomed with the X70 on normal lamp mode and it's more than bright enough.
Wouldn't worry too much about the spreadsheets and online calculators.. They're just there to confuse you
Ok just checked. Room of 4500 long, projector 470 long, allow 100mm at the back for cable curl and some air flow, leaves you with 3.93 metres from projectors lens to screen.
At max zoom you can get maximum image width of 2800 which is just short of a 120 scope screen. Now given that you would push the soft edge onto the velvet frame by say 20mm each side, leaves an active image width of 2760 at full zoom... So i'd say 115-118 scope will be the only doable size based on 3.93 throw.
If you push it back to leave 50mm at the back, you could just go 120 scope with a 2840 wide image at full zoom. Best to be safe and go around the 115.
Better still, set it up and put the screen in last after you know what will work.
OK fellas, I have figured out how I can get a full 4.5m throw distance in this room!
On the other side of the wall (thankfully it's exactly centered) is a microwave tower and oven. Just above the microwave pigeon hole is a plaster section (approx 700mm wide x 500mm high x 750mm deep) all the way to the ceiling. It would be hollow wasted space currently.
I'm thinking I might get a carpenter to build me a pigeon hole on the other side of the microwave tower, higher and closer to the ceiling so I can slot the projector into the pigeon hole so I can make use of the full 4.5m depth / throw distance this room can offer.
If I do this, can you please tell me what maximum size scope image I can get with the DLA-X30 at a throw of 4.5m? The far wall where the scope screen will be mounted to is 3.84m wide x 2.55m high.
Is a 130" scope image feasible at 4.5m throw with this PJ if zoomed in?
If so, what would be the max size of a 16:9 image on this 130" scope screen?
