Some come in HD
Can do a live feed straight from a video camera
Plays DVDs
Uses VGA cable
The further away you put the projector the less defined the image becomes
To prevent shadows being cast, you can invert the image which
means putting the projector behind the backdrop
of the stage.
You would use a long-throw projector over a short-throw one if you
have a large space. This is because the closer this projector is to what
it’s projecting on, the smaller the image. These projectors hit further
distances than short-throw ones so you could use them in a hall for a
Christmas show, for example, to depict the time
of day in the performance.

You can manually focus the image
Uses VGA cable
Has a USB input
Can play DVDs
Flip-out mirror (the image hits the mirror and is reflected)
To prevent shadows being cast, you can invert the image which means
putting the projector behind the backdrop of the stage.
You would use a short-throw projector over a long-throw one if you
don’t have a lot of space. This is because it can only ‘throw’ the image
being projected a certain distance before it starts to become pixelated.
If you use a phono lead to connect the projector to a DVD player you
could watch a film in your bedroom by projecting the image onto a wall.
