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.
I have actually tried these methods a number of times, your driver and the manufacturer's driver, it was a straight connection as well, nothing in between, and 3 different HDMI cables have been tested as well as 3 different monitors/tvs.
Thanks for the suggestion however.
In that case, and based on the troubleshooting steps done and recommended, I strongly recommend you contacting the system manufacturer so that they can check the unit and proceed with the warranty if necessary.
