I've always been a little itimidated by talk of resolution, progressive scan, line doublers, etc... everything to do with the quality of a video image. I'm wondering wether or not it would make sense for me to get a line doubler. My DVD player has progressive scan, and some of my video games have progressive scan... I have a fairly inexpensive projector, and I assume that it is not taking advantage of these progressive scan signals being sent to it. Would a line doubler give me better resolution and take advantage of the progressive scan, or is it possible that my projector has a "maximum" resolution, and there is nothing I can do to improve the image quality? This might not be a very easy question to answer with a simple written response... but any input/advice would be appreciated.
