Troubleshooting Intermittent Screen Glitches in a Dual Monitor Setup with AMD RX6800XT Graphics Card
Overview
Many users who operate dual monitor configurations experience unique challenges, particularly when it comes to display stability during intensive or specific application usage. Recently, some AMD RX6800XT users have reported intermittent graphical glitches appearing exclusively when running certain applications in fullscreen mode. This article explores common causes, troubleshooting steps, and potential solutions for resolving such issues.
System Configuration
- Graphics Card: AMD RX6800XT
- Monitors: Dual setup
- Main monitor: 240Hz refresh rate
- Secondary monitor: Vertical orientation, 165Hz refresh rate
- Notable Symptoms:
- Pixelation and graphical glitches occurring sporadically during fullscreen applications
- Glitches are application-specific and tend to resolve when the application is windowed or minimized
- Extended glitches (lasting over 5-10 seconds) may lead to driver timeouts or system instability
Problem Description
The issue reportedly began approximately one month ago, with affected applications including media players like Tidal and communication tools such as Discord. Users observe pixelated artifacts and visual glitches solely during fullscreen operation, with no perceivable triggers such as particular settings or actions. When an affected application is resized or minimized, the glitches typically disappear, suggesting the root cause may be linked to how the system handles fullscreen rendering.
Initial Troubleshooting Efforts
Several standard troubleshooting steps have been undertaken:
- Disabling Multi-Frame Parallax Offset (MPO): This feature, designed to improve performance on AMD cards, was disabled in an attempt to eliminate compatibility issues.
- Replacing Display Cables: Faulty or low-quality cables can sometimes cause signal disruptions; switching cables aimed to rule out hardware faults.
- Monitoring System Behavior: Observations confirmed that glitches are non-uniform and application-specific, often resolving on windowed mode, but not consistently.
Potential Causes and Recommendations
Given the symptoms, several factors may contribute to this problem:
- Driver Instability: Outdated or corrupted graphics drivers can cause intermittent display issues, especially in fullscreen mode.
- Compatibility Issues: Certain applications may interact unexpectedly with the GPU driver during fullscreen rendering.
- Hardware Limitations or Conflicts: While less likely, hardware conflicts or insufficient system resources could contribute.
Recommended Steps to Resolve
- Update Graphics Drivers: Ensure you have the latest AMD Radeon drivers installed directly from the official website. Consider performing a clean installation to eliminate previous
