Basically, the problem is that simple. If I view certain shades of gray (or colors close to it), there are some noticible streaks that run vertically on the screen. The image looks very dirty and the most noticible side effect is a bar runng down the center. This only occurs when running a signal through the internal scaler. When displaying 480p or 1080i material, this problem does not exist. I have no idea how I could possibly fix this issue or what the problem is in the first place. Any ideas?
