I have just bought an Acer RT270 monitor, set it up yesterday and everything was great. This morning I switched the monitor on but now none of the buttons, on/off or others are responding at all. I have tried holding down the power button, unplugging then plugging back in and swearing gently at it.... Nothing. Is it refund time or am I missing something? Thanks
