Need to return or RMA a brand new monitor?
If you find dead pixels within the 14-30 day retailer return window (Amazon, Best Buy, B&H), return it for a direct replacement immediately rather than filing a manufacturer warranty claim.
Inspection Instructions:
- Wipe your display with a microfiber cloth to prevent confusing surface dust with pixel defects.
- Click into fullscreen mode (F key).
- Scan your eyes systematically across the grid: top-left to top-right, middle, and bottom.
- Look for any persistent dark dots on colored backgrounds (indicating dead subpixels) or persistent colored dots on dark backgrounds (indicating stuck subpixels).
- If a stuck pixel is found, launch the Stuck Pixel Doctor to attempt resuscitation.
