Quick answer
Working USB peripherals do not prove that the laptop port, cable and dock support the required video connection. Check the complete video path.
Understand the issue
Record the laptop model, dock model, cable type and monitor connection. Test one display at a time and note whether it works through a direct supported output. That evidence makes compatibility questions much easier to answer.
Step-by-step checks
- Check the laptop port video capability.
- Confirm dock and cable requirements.
- Test one supported display connection at a time.
