Hardware Issues

• Loose connections – The most frequent cause
• Damaged DisplayPort cable – Even small damage can interrupt signals
• Faulty ports – Either on your monitor or computer

Software Problems

• Outdated graphics drivers – Your computer can’t communicate properly with old drivers
• Wrong display settings – Resolution or refresh rate too high for your monitor
• Incorrect input source – Monitor looking for signal from the wrong port

Configuration Errors

• BIOS settings – Sometimes needs adjustment for DisplayPort
• Multiple monitor setup – Windows might be sending a signal to the wrong display
