The BenQ LK953ST has a multi-screen projection feature! This is particularly useful at conferences, conventions, and other large meetings, where it is common practice to set up multiple projections of the same content, giving the audience multiple angles to view presentation content from. Several projectors can be hooked up to the same source, and the BenQ LU950 does this by using HDMI cables.
This is a significant improvement over the traditional VGA output, as HDMI signals do not decay over distances. Simply hook up one projector to the source with one HDMI, then daisy-chain the HDMIs all the way through your projector lineup. This will allow better accommodation of more people with an improved viewing experience for your large meeting. In addition to multi-screen projection, this same daisy-chain function can be used for image stacking.
Image stacking refers to two or more projectors being stacked, one on top of the other, to produce a brighter image. If you were to stack two BenQ LK953STs, then use the lens shift functions to overlay the images on top of each other, your projected image would measure around 10,000 lumens. Projectors with 10,000 lumen ratings often have a much higher cost than what you would experience buying two of these BenQs. Something to think about if your installation requires more brightness power!
