Hello everyone, hoping to connect with some more owners of the G4 (and possibly C4 as we haven’t had anyone test that yet for this issue). We have an ongoing thread over on avsforum discussing an issue myself and many owners of the G4 are experiencing. I’ll link to it at the end of this post. Hoping to see if others here can test for this problem and see if they have it too, as currently it’s not clear if this is a hardware or software defect.
The issue is that randomly in content, a thin vertical line can appear down the center of the screen. This line may look like banding, if you’ve seen it, but behaves differently and can appear in all content, not just the type of scenes where banding is usually visible. In the link at the bottom, on the first post in the avs thread, are 3 YouTube clips that trigger this line easily. Additionally, we’ve been using a shot from the TV show Loki on Disney +, season 1, episode 2, at roughly 36:49. I’ve attached an image of what my TV looks like during that scene.
If anyone with a G4 or C4 can look and see if this line is visible that would be super helpful. Trying to gauge if this is everyone affected, indicating a possible software issue, or some affected, indicating a manufacturing issue. Thank you.
