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 searched various Plugable KB’s and found what appears to be the newest and closest topic: https://support.plugable.com/t/dual-monitors-not-working/17575, which I followed to no avail (no joy).
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).
