Hey there JayTillu,
It sounds like there may be an issue with the cable, adapter, hub, or display you are using with your Mac. You may want to follow the guides we've linked below to properly troubleshoot why your monitor is not working with your Mac.
Use an external display with your MacBook Air
If your external display isn't detected or appears blurry when connected to your Mac
Have a good one!
No. My MacBook is working fine if I disconnect the Monitor. When I attach MacBook with External Monitor, then my monitor is flickering.
For Example, If I type text then I saw it after some seconds. When I hover the mouse it is also very slow. I'm not sure if this issue is with Keyboard & Mouse, Hub, or Monitor. I'm using dell bluetooth keyboard and mouse. And Hub is Novoo.
If I use MacBook's keyboard and trackpad then it works smoothly. No flickering on Monitor in this case. But when I use it with Dell Bluetooth and Mouse then monitor is flickering.
I read many articles on this. But none of the solution works me. I have just upgrade to new macOS.
