Is it better to use a Line Doubler, Quadrupler, or a Video Processor when converting non-signals to a DLP TV?
I have a Laserdisc Player and a VHS Deck, and still have lots of media for both, but when playing on my new Samsung 42in DLP (Model: HL-S4266W @ 720p) I can still see lines in the image. I have been trying to read up on improving the image, but I see so many ways to do it with additional equipment, but did not know which one would produce the best overall image.
I meant, Non-HDTV signals such as Analog.
Your TV will convert all signals to it's native resolution 720P. The TV does a decent job of this, comparable in quality to the line doubler built into most progressive scan DVDs. Your TV will never display any resolution other 720 progressive lines and therefore I don't think there is any piece of equipment that will make a big enough difference on a 42 inch screen. Video processing is usually something reserved for projectors displaying on a screen around 100 inches or more. If you are unhappy with your video quality I would start by making sure your TV is properly calibrated with one of the many test discs available. If you are still unhappy after calibrating the TV on your own, I might consider having your TV professionally calibrated this will deliver a much better picture then any piece of equipment.
