    Thank you for this tutorial. Updating the driver did not work for me, but your instructions got me to where I needed to go which was to roll back to the previous version of my ATI radeon driver.

    For those of you whom this did not help hopefully I can shed a little light on what my problem was. I went through all these steps and it did not fix the issue. I asked a friend who is computer savvy and he asked if the second monitor was connected to the video card. I checked and realized it was not. I knew this because my primary monitor is connected directly into the video card but I soon realized there was not another place for a VGA connection which a lot of monitors have. I do however have the option of getting a mini display port to vga or hdmi to vga. Hope this helps.

    I have an Hewlett Packard A7E32UTABA 90W Docking Station, and an HP laptop, and I'm running Windows 10. I connected 3 monitors to the docking station, however, it would only detect one. So I went to "Settings" to make sure all 3 of my monitors appeared under "Devices" and I added anyone that wasn't. After returning to my desktop, then I did a right click on my desktop and then clicked on "Graphic Properties", then I clicked on "Display", then I clicked on the "Multiple Displays" option, then I clicked "Extended Desktop", then I assigned each of the monitors to an individual drop down box in the "Select One or More Active Displays" section. And then Clicked "Apply" and now all 3 of my monitors are being detected.

    I have a 3rd monitor and it says no single. The other 2 monitors r working fine but the computer isn't detect it fully. It showing the 3rd monitor box in customize display setting but it not working. All monitors r connected to VGA, HDMI, & DVI (the 3rd monitor is connected to DVI that turns into HDMI on the other side of the plug to connect to the monitor). Is their away to fix it so I can use my 3rd monitor at the same time with my other 2 monitors?
