In-office environments, people usually use them in a well-lit room. Therefore, these projectors should be brighter than home projectors. Look for models that have a peak brightness of at least 2000 lumens or more. You might also want to consider the size of the room when choosing the projector. If the room is large, you need brighter projectors that can project larger images. If colour accuracy and speed are important, then go for LCoS, LED, or LASER projectors. These models can produce better contrast than traditional LCD projectors.
