I have a new Mac Pro which I intended to use for all general business and music sequencing in Logic. I have used the machine for about three weeks, in the last week since attaching a new Phillips Monitor 298P4QJEB I am not able to wake it up. I have tried altering all the settings in energy saver reverting to the original settings but this has made no difference. The only way the machine will wake up is if I reboot the Mac. Obviously this is not good. Can anyone help?
