Greetings! I bought a Plugable 3.0 UD-3900 model and just got my new desk, so I proceeded to setup the hub and my (2) HP VH240a 24" monitors. Initially - both monitors worked, but it had the 2nd monitor as #3, and vise versa. After unsuccessfully trying to “move” them using the Windows screen settings, I tried swapping the cables between the two monitors. The monitor #3 plugged directly into the HDMI slot works fine. The #2 monitor - plugged into the DVI slot and using the Plugable supplied DVI to HDMI adapter - stopped working altogether.
I ran the uninstall, eraser and reinstaller - but the hub still doesn’t see display #2. Windows 10 “sees” all three displays.
My machine is a 2018 ASUS TUF Gaming FX504 with the Nvidia Geforce 1050 graphics card. I purchased via Amazon and would appreciate your guidance (hoping I don’t have to mail it back).
PS just got done replacing FireCuda 1TB hybrid drive with 2TB SSD and 8Gb RAM was upgraded to 32 Gb (all tested and good) several days prior to receiving my new desk and installing the dual monitors and UD-3900.
You started off mentioning that initially, both monitors worked, but your two monitors were numbered unexpectedly in your Display settings. Then, you tried swapping the video cables between the two monitors, and that is when the issue started.
If you swap the video cables back to how they were originally, do both displays function again? Let’s take the next steps from there.
Hi Mitchell - yes - I swapped them back and forth repeatedly. Including after a reboot, after an uninstall and reinstall of the driver and such.
Right now - the system seems like “accept” working on the HDMI interfaced, but if I plug in the DVI 3rd cable - it blacks that screen out. I can run (2) monitors - the native laptop display and (1) HP 24" inch simultaneously - but not (2+) HDMI nor DVI monitors at the same time. See the above error msg from MS Windows 10 Device Mngr.
With the error message aisde, this behavior sounds like while the external display is being detected, it gets disabled upon connection of the additional display.
I would like to check to see if it is being shown in the Display settings page. To do so, please follow these steps:
Close or minimize any open windows, then ensure all monitors are connected (even though one is not working)
Right-click on the desktop and select Display settings from the drop down menu
Under Rearrange your displays, select the “greyed out” display from the diagram that you are having issues with a single left-click on the icon. You can click “Identify” to help you understand which monitor corresponds to which number label
Scroll down to the bottom and select Extend these displays from the drop down under Multiple displays
Please let me know if if this helps, or if you do not see these settings.
With all three monitors visible by Windows 10, the #2 monitor is depicted as grey’d out and slightly smaller than the 15" laptop and 2nd 24" HP monitor. It lets me move only the laptop #1 and monitor #3, but not the grayed out monitor #2.
At this point, I’d like to request some logs from your computer to investigate the error and current state of dock when connected. Could you please keep the UD-3900 connected to your computer (with both displays still attached), then navigate to our PlugDebug tool and follow the instructions there?
Please send the ZIP file it creates to us directly at support@plugable.com, and include “Ticket #323422” in the subject line to help match up the details to this case.
Looking through the logs, the first thing that I notice is that only one of your HP VH240a is being recognized in your Display settings. Assuming both HP monitors were connected at the time of log capture (and that the two HP monitors are not set to mirror each other), this is a bit unexpected given your original mention that Windows is seeing all three displays.
I understand that you have already tried re-installing the DisplayLink driver. I’d like to do so following our standard re-install procedure, which also includes our latest validated DisplayLink driver version. To do so, please follow these steps:
Disconnect the dock from the system and please remove the power cable from the dock so it turns off completely (this is important so the unit resets). Please keep it disconnected until the last step
Uninstall any and all software with ‘DisplayLink’ in the title that is present from within the Control Panel → Programs and Features. Don’t worry if these entries are not present or if the process does not work, just move onto the next step
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
Please let me know if this makes any difference with the DVI-connected display.
No worries at all. Thanks for capturing that second set of logs.
In this most recent set, I see both HP monitors recognized by the computer. However, one is being set to disabled by the computer.
I provided the instructions for enabling a display that is set to disabled previously, but I understand that you stated the system is indeed set up for extended mode. Can you double-check if that setting “stuck” after you changed it? It could have reverted back to “disabled”.
Close or minimize any open windows, then ensure all monitors are connected (even though one is not working)
Right-click on the desktop and select Display settings from the drop down menu
Under Rearrange your displays, select the “greyed out” display from the diagram that you are having issues with a single left-click on the icon. You can click “Identify” to help you understand which monitor corresponds to which number label
Scroll down to the bottom and select Extend these displays from the drop down under Multiple displays
