Hi,
I have my macbook air connect with LG 27" display for a few months. It was working fine.
Yesterday, I try to connect the display as normal. However, the screen told me "No Signal".
I try everything. change the cord, adapter, etc. trying my monitor with other macbook air it is working fine.
BUT when I turn the output to 1280*720 It was working ! only with this resolution...
Thank you

I found that the problem come from the broken of my thunderbolt port.
