How come my LG monitor won't work in Mojave like it did before the upgrade?
Did the Mohave upgrade. Now my LG monitor will not work on my iMac, like it did before. What give Apple??

My LG monitor/external display was working JUST FINE until the upgrade to Mojave.
maggySwim,
Thanks for getting back to us. Can you let us know what happens when you try to use your display now? Is it not detected by your Mac or something else? What is the exact version of your Mac? Check by clicking > About this Mac (Upper left corner). What is the model of the LG monitor?
We look forward to your response.
LG Monitor is Moel 22MD4kA
Prior to the upgrade to Mojave, it was running just fine as a second screen. Plugged into a power supply, and then a direct connection from monitor to screen. Additional photos attached.
Thanks for the additional information, maggySwim.
Next, we suggest contacting LG to see if there are any firmware or driver updates for your display: Get Product Help & Support | LG USA Support
If that doesn’t help, contact Apple Support.
Best.
