The "6in1 Hub with DeX function (USB-C, 6 ports)" from 4smarts is basically compatible with many modern laptops and notebooks, but there is no specific information on compatibility with the Asus ROG Strix G18.

- The hub supports operating systems such as Mac OS and Windows, which indicates that it should work with most USB-C enabled devices.
- However, there is no guarantee that it will work without issues with specific models such as the Asus ROG Strix G18, especially when it comes to specific hardware configurations or BIOS settings.

To ensure that the device is compatible with your Asus ROG Strix G18, I recommend checking the technical specifications of your laptop and contacting the manufacturer or 4smarts customer service if necessary.
