Can I use my existing projectors as part of a GeoWall?
Maybe. If you already have a DLP projector you need to check if it will overheat when next to another projector. It is best to have two identical projectors so that they have the same optics. Also, the bulbs on DLP projectors degrade over time so you want to have bulbs that have had similar use. At the end of their 2000-hour life, an Infocus 530 projector will only put out about 1200 lumens. This is down from 2000 lumens when they come out of the box.
