DisplayLink Forum - View Single Post - iMac will not recognize monitor connected with Display Link VGA to USB 3.0 adapter

Background info:
-Im running a Quad-Core Intel i7 - 2016 ish
OS is Catalina 10.15.5
-Running Parallels/Windows 10 in addition to Catalina
-Trying to connect a View Sonic monitor (VG2230wm) that is about 12 years old using a VGA to USB adapter - CD0032
-My work PC laptop recognizes the monitor with or without the CD0032 adapter and does so automatically so I know the cables and adapter work

Here's what I've tried:
- Installed latest driver from Display Link website
- Tried all the USB ports, none work
- Went into system report / Extensions"and verified that DisplayLinkDriver is loaded and loadable
- Attached monitor to another computer (Toshiba PC Laptop) which recognized the monitor immediately and without having to hit "detect" in settings
- Tried option/detect"in Mac OS display preferences
- Tried "detect" in Windows 10 on iMac
- Opened AirPlay display device which brought up "arrangement" option but it still didn't detect the monitor so I couldn't control it ( I read that this was a possible fix even though it makes no sense to me )

I'm out of ideas. Is it possible the Mac OS cannot detect such an old monitor?
