Upping the resolution in my profile reduces the effect, but it is still very very noticeable. I don't see it when the coax is plugged directly into my tv. The cable comes from comcast in the san francisco bay area. I've read about similar problems on ALL channels, but I only have the issue on some lower channels. 2 and 13 are the worst. Most other channels such as espn or tbs exhibit no ghosting or gray lines at all. I suspect this is a cabling or interference issue, but I thought I'd check to see if there are any channel-specific settings that I should make. I have a screen shot here with some highlighting here: Bad: http://rackle.com/gray-bars-and-ghosting.jpeg Good: http://rackle.com/no-bars-no-ghosting.jpeg Admittedly, not apples to apples. More info below.
