If your PRISM+ monitor is flickering, flashing, or showing strange lines or colors, this guide will help you identify and resolve the issue.
🎞️ What Is Screen Flickering?
- Quick black flashes or brightness changes
- Horizontal or vertical lines
- Random color shifts or static
- Intermittent signal loss (screen goes black then recovers)
These symptoms may be caused by:
- Loose or incompatible cables
- Incorrect refresh rate or resolution
- Graphics card (GPU) compatibility issues
- Electrical or environmental interference
🔍 Troubleshooting Steps
✔️ 1. Check Your Connection Port
- HDMI 2.0 supports up to 60Hz at ultrawide resolutions (e.g. 5120 × 1440)
- DisplayPort 1.4 supports higher refresh rates (up to 120Hz or more)
- Try switching to a different port if available
Tip: Refer to your monitor’s manual for port-specific refresh rate support.
✔️ 2. Inspect Your Cable
- Use the original cable provided with your monitor
- Check for damage, bent pins, or loose fit
- Try a certified DisplayPort 1.4 or HDMI 2.1 cable
- Test with another known working cable
✔️ 3. Confirm GPU Compatibility
- Ensure your GPU supports the monitor’s resolution and refresh rate
- Laptop users: confirm external output supports high refresh rates
✔️ 4. Adjust Monitor Settings
- Windows: Settings → Display → Advanced Display Settings → Set refresh rate (e.g. 120Hz)
- NVIDIA: Control Panel → Display → Change Resolution → Set to 5120 × 1440 @ 120Hz
- Toggle FreeSync or G-Sync settings if available
✔️ 5. Ensure Stable Power
- Plug monitor directly into a wall outlet
- Secure power cable connection
- Try a different outlet
- Remove nearby electronics that may cause interference
✔️ 6. Rule Out Software Conflicts
- Update GPU drivers via NVIDIA or AMD’s official site
- Disable hardware acceleration in browsers or apps
- Test monitor with another PC or laptop
