Hello to all
(sorry for my bad English, use a translator)
Let me try to build a projector in fullHD, but I doubt a strong underpinning of all, I tried with the "focalcalc143" to see if I could get a screen about 110 inches projecting from a distance of 5 meters, it seems possible with triplet of 600mm but I could not find it anywhere.

Kindly someone you know tell me if what I wrote is true or I wrong in something?

Thanks again to all for the answers

If you want 1080p, you'll probably want to buy the 15.4 LCD Kit from johnzo. If you use the Pro Lens Kit (650mm front fresnel, 220mm rear fresnel and 500mm triplet), your FocalCalc should look like the image below. This will give you a 110" screen at almost 13 feet. Your projector enclosure will be about 3 feet long, front to back.

If your room is 5 meters (15 feet) long, you can subtract the three feet of the projector, since the throw is measured from the triplet to the screen. Moving the projector closer will result in a smaller screen size and moving the projector further back will result in a larger screen size.

Quasi_Mojo Thank you for your interesting reply, and I apologize for the time past, but I was out of town.

I wanted to clarify some measures, the room measuring 6 meters
to 4.5 metres and 5 metres which meant I had the distance of three to plan projection.

Starting from this distance of 5 meters (16 feet) from the values I was obtained under the programme focalcalc a triplet of 600 mm and is the one that I could not find then asked you who you certainly much more experience than me.

Maybe just taking into consideration a draft projection 1080P wanting to obtain a projection screen from 110-120 inches taking the projector on the wall in support of 4,5 meters, I recommend what to do and possibly where to find the various components, please note that I live in Italy.

I thank you still agonize for the time allowed.

Ciao Ciao....

I understand that English isn't your native tongue, but I'm having a little trouble understanding you.
Perhaps if you draw up a floor plan of your room (even using MS Paint) and post it here (including where you would like the seating, screen and projector), We can work with that and show you what is possible.

If you need directions for uploading pictures, look here: How do I upload pictures to the Lumenlab Forum?

Quasi_Mojo thanks again for your reply.
Did I send a small sketch of the room that will be dedicated solely to films.
In the sketch are listed:
A projection screen =
B = Projector
C = Window
D = Door

What I meant about 5 meters is the distance (on the design is expressed in millimeters 5000) by three to the projection screen on the wall supported taking the rear of the projector.
This time I hope to have been more clear, and sorry again for my English ....

I hope I have done well to attach the image

Hello

A pro lens straight shooter will be about 1,4m in overall length. Given the 6m room, you may have to move the projector forward from the back wall a bit with a 15,4" LCD in order to acheive the desired screen size. Your seating area will still be forward of the projector, and should be fine.

It is important to note, however, that LCD sizes are measured diagonally, and therefore the screen size that the focal calculator will give is also measured diagonally, and is not the screen width. This may mean that the screen size will be perfectly adequate as is.
