Plugable USB 3.0 - HDMI works but DVI/VGA port doesn't work when connecting to monitors

I have Plugable USB 3.0 Universal Laptop Docking Station for Windows (Dual Video HDMI and DVI/VGA) docking station. Everything works except the second monitor through DVI/VGA port! The HDMI port also works. Can you please help! I got this dock so I can use dual monitors and its not working as it says it should.

To connect the second monitor: I am using DVI to VGA adapter that came with the dock station and VGA to VGA cable from adapter to the monitor. I tried 2 different laptops but same issue in both (Lenovo Flex 5, Lenovo T470p).

Hi, not sure if you solved this yet, but I came across this when having the same problem. I found a solution for my issue and wanted to share in case it helps you (and others) too. It was pretty simple once I found it, just took a long time to find!

You need to open display settings in windows (easiest way is to right click on your desktop background and select “display settings”). Then scroll down to the “multiple displays”, which will be near the bottom. In the drop down selection, choose “extend these displays” - duplicate would also work I think, but probably not what you are trying to do. This fixed it instantly for me, hopefully it does for you too :slight_smile:

Issue is resolved!!! Basically the second monitor has 2 ports - HDMI & VGA. I had connected the laptop with VGA port and from the monitor, HDMI cable was also plugged in (second end of HDMI cable was not plugged in anywhere). When I removed the HDMI cable from the monitor, it instantly detected the laptop connection via VGA port! :slight_smile:

So i guess monitor was confused on what to connect to and was giving HDMI a higher priority. Taking it out solved the issue! Thanks guys :slight_smile:
