Confused over aspect ratios

[Camalot]

Hi guys,

I'm building a new cinema screen with a ceiling mounted projector and want to get the screen measurements correct.

I'm using the projector central calculator but not sure if i'm supposed to get the measurements in 16:9 or 16:10.

The GT750 GT projector says its 720p with a native res of 1280x800, would this mean i need to build my screen to a 16:10 ratio?

Also, would this mean all 16:9 movies / content will be displayed on the screen with a border top and bottom?

Thanks guys!

Many thanks, i'll go with the 16:9 ratio.

Is there anywhere you know of that can custom cut me a sheet of MDF to the correct size so i can paint!?

B&Q. You do know though that in standard sizes the biggest sheet size is 2440 x 1220 mm.

Yea noticed yesterday,

I think i'll just paint a section of the wall instead, and border it off with a black painted MDF border!
