If multiple lamp-based projectors are used, not only would the bulbs fail regularly, they will dim at different rates, causing color and brightness shifts. Projectors with laser light engines offer a significant advantage over a bulb-based system in a long-term projector blended installation. However, Edge Blending can’t be combined with pixel shifting but that is okay in many situations where maximum flexibility is more important than absolute resolution. The result is an image that looks seamless, like it’s being displayed by a single projector. You can use the projector’s Black Level setting to make the difference even less noticeable. Sony, Hitachi, NEC and Optima are OEM examples, they make the projector and design the lamp that goes into it, they then supply the part to be replaced.
