Based on the description I recommend you doing the following:
- Uninstall the current driver from Control Panel or from Device manager.
- Download the driver at the link:
- Test a different HDMI cable.
- Use the HDMI port with straight connection (no video adapters).
It is important to mention that the driver that we provide is generic drivers that may work on your system. Due to this reason, I recommend you contacting the system manufacturer of the laptop so that they can give you the driver that has been designed specifically for their system.
