Only one monitor working - Alienware 15 R3 - UD-ULTCDL


#1

I purchased the Triple Display Docking Station for use with my Alienware 15 R3. Everything seems to be working fine, but I’m having trouble getting the dock to recognize the second monitor (not 4K) through either the second HDMI port or the DVI port.

HDMI 1, USB ports and Ethernet seem to work fine, but I need a dual monitor setup.

Hello azellermeyer,

Thank you for contacting Plugable support! I’d be more than happy to assist you with this issue.

I suggest a clean installation of the newest drivers:

  1. Disconnect the dock from the system and please remove the power cable from the dock so it turns off completely. Please keep it disconnected until the last step.

  2. Uninstall the DisplayLink Core software from the Control Panel -> Programs and Features. Don’t worry if this fails, just move onto the next step

  3. Download, extract and run the DisplayLink cleaner tool, found here --> http://www.displaylink.com/downloads/… and ensure it displays “Cleaning Complete”
    when done (video walk-through if you need it -> https://youtu.be/AcVV1gD_FvI)

  4. Once the Cleaner has been run, reboot (even if not prompted to)

  5. Now download and install the 8.1 M0 DisplayLink software, found here --> http://www.displaylink.com/downloads/…

  6. Reattach the power cable to the dock first. Once the dock is powered on, reconnect it to your system which will trigger the final portion of the installation. If the device is not detected, please reboot the system.

If that fails we have a troubleshooting tool that helps us find out what is going on in situations like this. Please plug the dock into your computer, then go to this page and follow the instructions there:

Please don’t hesitate to let us know of other questions.

Thanks again for contacting Plugable support and best wishes!

Hi Joshua,

thank you for the help. Both displays are working, however, the main display does not connect to my system’s GPU.

My setup:

System: Alienware 15 R3 (7th gen Core i7)
GPU: GTX 1060
Monitors: 2 x LG 22M37D connected via bi-directional HDMI to DVI cables.

So I have noticed that it does work while the lid on the laptop is open, but once it is closed it is using on board graphics.

Hello,

Thanks for the update. Sorry for my delay over the weekend.

So if I understand correctly: when the lid is closed the NVIDIA GPU becomes inactive and the Intel graphics takes over?

This may be a limitation of how Dell has configured the Alienware hybrid graphics to run. You may need to keep the lid open or contact Dell to see if they have a solution for this.

Best,
Josh
