New install of W7 Ultimate on a freshly-built Shuttle SX58-H7, i7-920, 6GB triple channel, Radeon HD5770, Patriot Torqx SSD system drive, WD 2tB green drive for data, old trusty ViewSonic 20" LCD. Latest video (and all the rest too) drivers installed. Everything works beautifully except that the blasted monitor refuses to go to sleep and I'm too lazy (and forgetful) to turn it off manually more than occasionally. Does this ring a bell for anyone? I've looked around but haven't turned up anything. Searches on MS's site are hopeless unless I know ahead of time exactly what terminology the KB writer was thinking of at the time (and sometimes not even then). What is it that Windows monitors to see if a computer is "idle"? Keyboard, mouse, something else?
