I restarted my Samsung Monitor which is connected to a Mac computer, I then realized a blue flashing button on the on/off button in the bottom right corner of the monitor. On the screen it says 'Check Signal Cable Analog with a small red square, green square and blue square. I have tried quite a lot to fix this problem so any help would be appreciated, thanks.

Does you computer have onboard video only or is there a video card inside? If there is a video card make sure that the cord is connected to it and not the motherboard video connection.
