Digital projectors are an excellent presentation devices, used to capture an audience with their ability to deliver clean crisp images. They can be plugged directly into a laptop/PC, DVD player or video recorder. While digital projectors have many great benefits it is worth considering the initial cost of a projector as well as the high cost of replacement bulbs.
The alternative is digital projector rental. For a fraction of the price you can hire all the necessary equipment you need. LCD projector rentals tend to be the most flexible but other things to consider are screen size and colour.
Make sure the screen has the same aspect ratio as the projector otherwise your image will not fit the screen. Aspect ratio refers to the dimensions of the image being projected. This is not the same as size of the projected image. Aspect ratio refers more to the shape of the projected image. The most common are 4:3 or 16:9 for widescreen usually on newer models.
Other things to consider are screen size, the size of the screen you will need this depends on the size of the room aswell as the size of the audience. The minimum distance a viewer should be is twice the width of the screen and the maximum distance should be no more than six times the distance of the screen.
Throw distance is the distance a projector can project an image, most projectors will have an ample throw distance for most boardrooms or classrooms however if your planning to use a projector in a large venue you may need to look at renting a professional digital projector.
Also the projector you will need will depend on the ambience of the room and the control you have over that. You will need a digital projector with more lumens if the room is brighter, Usually 1000-2000 lumens should suffice but if the room is quite bright you may need 3000+
The main benefits people find for renting digital projectors essentially comes down to the cost. Is it worth spending hundreds maybe even thousand of pounds on something that you wont be using a vast amount of the time when you can rent them affordably and easily.
Its clearly cheaper to rent a projector when you also take into account the cost for replacement bulbs. Digital projectors aren't particularly easy to transport and can be easily damaged when being transported. Renting prevents the hassle of fixing them if they were to get broken.
