macOS Incompatibility:
Are you really using macOS 10.2? That is not an option for a 2017 MBP. If 10.2 is the macOS, incompatibility would likely be the culprit in that case.
Troubleshooting Monitor Connections:
A. Links to refer to:
- Connect a Display to your Mac - Apple Support
- Use an External Display with your MacBook Pro - Apple Support
B. Single Out this User:
For temporary use and troubleshooting purposes, create a new Administrator User, seeing if all shows up as it should. If so, then it is likely an issue with the current user itself. Once determined, delete this Administrator User.
C. Reset your SMC and your NVRAM:
Sometime, changes (i.e. Update Installations) are made, and then settings (i.e. Finder GUI) become manipulated, technically. So, reset both. Note that is may take a few tries just to reset them successfully.
