When Windows detects no keyboard/mouse activity for the set number of minutes, it starts the starts screensaver or signals the monitor to go into powersave mode.
We do not want the OS the wake the monitor up in response to unintended mouse movements or optical mouse jitters that plague low-cost mouses.
We need to modify or hook into the way the OS wakes the monitor up. Ignore movements of less than N pixels, or movements that are not smoothly continuous for at least M milliseconds.
Alternatively, is there a way in WinXP to tell the OS to ignore mouse inputs altogether, when in screensaver mode?
As much as possible, power down that energy-sucking 3D graphics card when in monitor is in powersaving mode.
