Large-format projectors, or large-venue projectors, are the NASCAR racers of projectors. These are projectors with some lumen horsepower behind them and built for performance; bright, powerful, and able to project large-scale images for entertainment, meetings, command and control, simulation, and myriad other applications requiring a large image. Across the board, these projectors are capable of displaying HD images and some are even 3D ready. Of course there are a few different imaging systems to choose from including LCD, 3LCD DLP, BrilliantColor DLP, and D-ILA LCoS, with some representing incremental advancements to existing technologies. Each exhibits its own pros and cons, but all are proven technologies nonetheless. Some manufacturers are incorporating onboard processing into the projectors to facilitate using multiple projectors for edge blending or tiling for an even larger display area.
Total cost of ownership (TCO) is an important aspect to consider in a projector. The cost of replacement lamps represents a substantial part of ongoing expenses over the life of a projector. The bulk of these projectors use at least two, if not four, lamps to achieve the high brightness levels required for this category. Most offer an eco mode, short for economy mode, which effectively reduces the overall brightness but extends the lamp life. You might also see the word “eco” used elsewhere on the product literature where it has another meaning entirely–in this instance referring to the ecology and the manufacturers' efforts to be environmentally responsible.
Filter maintenance is essential to keeping the electronics cool and airborne contaminants out of the imaging systems and as such also factors into TCO. And manufacturers have addressed it by developing extended life filters, auto-advancing filters, and some even offer filter-less operation with sealed optical engines. Additionally, projectors are becoming more energy efficient requiring less power to attain their rated brightness. And while many can run off 100 to 240V via auto-switching power supplies, some do require 220VAC to operate.
We’ll be looking at models capable of producing 5000 lumens or greater.
