I've been using Macbook Pro 13'' 2011 connected to an external monitor (Samsung SyncMaster SA300) through HDMI to VGA adapter for a few years without any problem. Today, I cleaned my desk so I unplugged the monitor's cable to turn it off. When I'm finished, I plugged it back in and it showed "Check Signal Cable".
I checked everything like the power adapter and the cable connected the monitor to the HDMI to VGA adapter and they were all connected properly. Then, I disconnected them all and reconnected them back but it didn't work. I even restarted my machine but still no luck.
After that, I searched on the net and someone said that the monitor was not using VGA input. It was using DVI input by default when it turned on. The input means port/slot, I assumed. There are two ports at the back of the monitor: VGA and DVI. I was connecting my laptop to the monitor through VGA port but my monitor was expecting signal via DVI port.
To solve it, I pressed the button on the monitor to switch it to using VGA input. The image below shows the button's icon in a yellow circle.
