I can't get the VGA port to work. What should I do? Try some of the following steps: 1. Confirm if the connected USB-C port of your device supports DP Alt Mode. To do this, please consult your device's user manual, contact the seller, or check the manufacturer's website. 2.Try a different computer and VGA cable to see if the issue still persists. 3.Plug your VGA cable directly into your device and see if you get a stable connection. If you can't get a stable connection, then the problem is with your VGA cable. 4.Verify that your monitor is configured to the correct input (VGA). 5.We provide you with 1 year after sale guarantee.
