Understanding Display Anomalies After Upgrading to AMD Radeon RX 9070 XT on Windows 11
Overview
Experiencing display issues following hardware upgrades can be both perplexing and disruptive. If you’ve recently upgraded to an AMD Radeon RX 9070 XT and installed a fresh version of Windows 11, you might encounter visual anomalies such as vertical blue lines and intermittent black screen flashes. This article explores common symptoms, troubleshooting steps, and potential solutions to address these issues effectively.
Symptoms Observed
- Thin Vertical Blue Lines
- Visible on the desktop and during application use
- Not detectable during BIOS initialization
- Prominent during screen sharing sessions (e.g., Discord)
- Absent in some games such as Palworld
-
Disabling hardware acceleration in applications did not resolve the issue
-
Intermittent Black Screen Flashes
- The monitor briefly goes black then reappears, mimicking a reboot or signal loss
- Occurs randomly during Windows or application use
- Resilient to HDMI cable swaps and port changes (cables function correctly on other displays)
- Adjusting refresh rates and display resolutions failed to resolve the problem
Troubleshooting Steps Undertaken
- Removed outdated NVIDIA drivers using Display Driver Uninstaller (DDU)
- Performed a clean installation of the latest AMD Radeon Adrenalin drivers tailored for the RX 9070 XT
- Tested multiple HDMI ports and cables
- Disabled hardware acceleration settings across applications and browsers
- Confirmed that visual artifacts do not appear during the BIOS phase
