Was just wondering on the meaning of Convergence as it has been mentioned on the forums of late and i am interested to know what is meant when one says that the Convergence was spot on in terms of a projectors image.
It means the red, green, and blue light engines all converge in the same spot. If one is off, you can have a slightly blurry image or in really bad cases, light bleed along sharp lines. Here's an old YouTube video that explains it pretty well.
