⚖️ Seller Warranty & Marketplace Dispute Conciliation

Warranty service should be sought if, after following all self-resolution steps and checking cables/power adapters, the monitor exhibits manufacturing defects such as screen failures (persistent dead pixels, internal spots, fixed vertical/horizontal lines), internal graphics card issues preventing basic operation, or failures in the original power supply not caused by misuse. These are defects that cannot be resolved by the consumer and are covered under warranty.
