Hi Katie - The control panel is making things a little difficult! (making you put it in extend, before choosing a different main display).
So let’s tackle this from two completely different directions.
Here’s a little crazy instructions on how to get extend working with one monitor blank and potentially hiding some of your windows:
- First, hit the Windows-P key combination and choose “Extend”
- Move your mouse onto the laptop screen, right click on the desktop and choose “Screen resolution” to open up that control panel
- if you can’t see the Screen Resolution control panel, we just need to move it onto the visible (laptop) monitor. You can do that by holding down the “windows” key on your keyboard, then in combination hit the right arrow key a bunch of times, and then the left arrow key a bunch of times, until you see the control panel show up on your laptop screen (the windows-arrow keys move the windows left and right across your monitors).
- Click the checkbox to change your primary monitor, and Apply.
Your laptop screen should have everything and be working now. Now, if the USB screen is still blank, we want to generate DisplayLink logs to figure out why that might be. Here’s how: http://plugable.com/support/displayli… Just email the .zip file it places on your desktop to firstname.lastname@example.org
Let us know if this is too complex or any trouble - thanks thanks for emailing that support file. For a monitor to work in duplicate but not extend, this is likely something small and simple - we just have to figure out what it is!
Thanks for your patience!
