Track your monitor, GPU, or cables for issues.
Track your monitor, GPU, or cables for issues.
Recently I'm unsure whether my monitor, GPU, or cables are failing. I notice numerous lines across the screen, which is unusual. The issue keeps appearing frequently, and I'm considering giving up on fixing it. I've tried different cables with another computer, but the results vary. This problem has persisted for about 3 to 5 weeks now. I need to determine the best way to resolve this.
To accurately evaluate cables and displays, switch them out systematically. Start with cable A and monitor A, then test cable A with monitor B. Next, try monitor B with cable B, followed by monitor A using cable B. Consistent outcomes across these setups suggest a GPU issue. Since the same problem persists on another PC, it’s likely not related to the GPU itself.
I worked with several cables and input configurations, but the outcomes were highly unpredictable. This has kept me stuck for a while. I've tested different displays, which seemed okay at first, but the DP cables didn't provide consistent specifications across monitors. Specifically, when using Cable A for Monitor A and B, Monitor A supports FreeSync/GSync features, whereas Monitor B doesn't allow it, even though both monitors have identical specs.
