Okay, I will try to explain this as well as possible. Those of you that know might find it easy to know what this is and if there is a solution. I have a Infocus 4805 and a Dalite screen. When there is a snow scene (like Hoth from ESB) or a water scene (Finding Nemo), I will get a "digitized wavy line" across (horizontally) my screen. It is like a distortion, or fuzzy line that vibrates or waves a little. I only notice it when the background is only primarily one color. The "line" is thin - it does not take over a large percentage of the screen. I have AVIA but have not used it yet. I don't think it has anything to do with color calibration though...but I might be very wrong about that too. Well, what do you think?
