Hello , normally I worked using an external display, and since I update my MacBook Pro to catalina OS 10.15.4 , I'm having issues with the monitor ASUS VZ239H, for instance when I left my work office for some time , when I back the monitor doesn't work and I have to disconnect and connect again to continue however some times the resolution of the monitor goes to 720 instead of 1080.
I'll appreciate any help.
Best regards

Hi there, fzuniga1971.
I see that, when you've stepped away from your MacBook Pro, your ASUS monitor has disconnected and the resolution of the monitor is changed. The began after updating your Mac to macOS 10.15.4, and I'm glad to help with this.
Get help with video issues on external displays connected to your Mac -- This article provides the information and steps that you need under "Detect your display” and "Check connections".
How to use safe mode on your Mac -- If your ASUS still disconnects, restart your Mac in safe mode and see if your external display is still connected when you've left it alone. If it happens while in safe mode, follow the steps under "If the issue continues in safe mode". If it doesn't, the steps to use is under "If the issue doesn't continue in safe mode".
Let me know how that goes, and take care!
Hello, I tried to Start with safe mode and the issue was solved, the MacBook Pro works fine but yesterday it happened again , I did the same procedure but it didn't work , finally I changed the port where I used to connect the display and works again.
Today I read about another issue when the Mac goes to hibernate so seems like there are more issues, since in the publication recommended to wait the MacOs update .
In the mid time, I'll following the procedures in case it happened again.
