The computer cannot turn off the monitor. It can only tell the graphics card to turnoff the signal to the monitor. My monitor then displays 'No signal detected' in a box and puts itself into a low-power state awaiting a signal. Even if the monitor does not do that, a black screen should use less power. Why the turnon does not work, if indeed it does not (and the monitor is not failing to respond to its resumption) is not a Python question. 2 and -1 as off and on parameters is a bit strange. The OP might try a different api reference source or ask on a windows innards list. -- Terry Jan Reedy
