How do you measure a IWB? Is it diagonally like a TV? Trying to work out how big my existing ones are so i can sort out these new projectors.

6. You measure the diagonal, times it by the distance between the projector and the board (measured perpendicular to the floor), add on the width of the projector's lens, and then divide the whole lot by the number of days in the month.

And unless you do this standing on a stool it won't work.

That's a very advanced technique. Remember to only rub your belly clockwise and have some gravy granuals on hand just in case.

17. it's not just diagonal size thats an issue though, as the newer SMART range is also available in the 16:9 orientation, rather than just 4:3

as, obviously, are some projectors.

Best to check if they look widescreen
