Plugging in a computer looks pretty good. Its the DVD player, Dish Network tuner, and Xbox connected via Svideo that I am trying to improve. two of the three have component out options. There are too many variables right now that might be causing the less than desirable quality that I am not sure where to start: cables, lamp, projector itself. I know my home-made screen isnt helping but I tried a sample of a da-lite high power screen and while it was much brighter, it still suffered from detail loss.
