I solved mine !!
i tried diff adapters, update drivers, etc. also did not work.
and my Mac Book Pro does not have "Graphics: Higher Performance" option in my System Preference Display page.
then i tried cleaning the System Preference (Restart, Option + Command + P + R) and now i can use my external monitor!
my spec:
Model Name: MacBook Pro
Model Identifier: MacBookPro5,5
Processor Name: Intel Core 2 Duo
Processor Speed: 2.53 GHz
my symptom was:
- I can connect to my office external monitors (yes, it works with more than one)
- but i cannot connect to any other external monitors
- when i plug the cable, my Mac Book screen flash and then not detecting any external monitor

SOLVED for me by:
ReplyDelete1) Shut down all devices and unplug for 3 minutes
2) Plugin
3) Power on computer while holding down the shift key to start in safe mode
4) Restart computer in regular mode
My display came on at step 3 and is working now.
