My problem? From what I'm reading, scan lines or PWM sensitivity.This doesn't sound like a PWM problem. Most monitors are edge-lit, so PWM wouldn't produce lines or bars. PWM is also tied to the refresh rate on most monitors, so it should be less noticeable at higher refresh rates. This seems more like an issue with the way the monitor is dithering. AMD cards also dither, so the two dithering patterns might be clashing and producing the artifacts you're seeing. Check the Catalyst Control Center under "Information" -> "Software" to get the 2D driver path. Then run regedit.exe and open that path in the left pane. You should see values in the right pane like "AdapterDesc" and a bunch of settings. Add a DWORD value named TMDS_DisableDither (for DVI) or DP_DisableDither (for DisplayPort) with a value of 1. Then reboot and check if the artifacts are still there. If that doesn't help, the monitor might be defective, or it has crappy dithering at 144 Hz. |
