How is projector placement calculated?
For any given projector, the width of the image (W) relative to the throw distance (D) is know as the throw ratio D/W or distance over width. So for example, the most common projector throw ratio is 2.0. This means that for each foot of image width, the projector needs to be 2 feet away or D/W = 2/1 = 2.0.
How far back should a projector be from the screen?
Short throw projectors need to be between 5 and 10 feet away from the screen, depending on how large of an image you want. Short throw projectors have a throw ratio between .
Does a projector have to be centered?
Ideally, the center of the projector’s lens should align with the horizontal center of your screen, although some projectors do allow for offset installation. If you can’t have your projector dead center, for whatever reason, be sure to look for projectors with a lens-shift feature.
Will a projector work on a slanted wall?
Can a projector be used at an angle? If the projector is angled towards the screen, instead of being centered in front of it, images will be distorted. However, you can use the built-in keystone correction to correct the image angle. With a little effort, you make an angled projector work for you.
How does a projection calculator work?
Since each projector lens is different, an online projection calculator tool will help you calculate the size of an image on a screen relative to how far the projector is placed from screen.
How do I Map my projectors?
Once you run your cables, power your projectors and sort out which output is for each projector specifically, you’re ready to start mapping. The first part of this is typically aligning all of your projection together.
How many projectors do I need for a good projection mapping setup?
This and pixel density (size of each pixel) are the biggest factors in a weak or underwhelming projection mapping setup. In this case, we chose to go with four 22,000 lumen HD Projectors to get maximum brightness and quality without having to triple-stack or try to align 6-8 projectors.
How do I determine my projector screen size and throw distance?
Use our Projector Calculator to determine throw distance and optimal screen sized based on your projector. Use our Viewing Distance Calculator to figure out the optimal seating distance for your audience based on the projector screen size you are considering.
