Hey Kevin,
About eyestrain to release that problem there is currently two solutions on this system.
1) With task scheduler it changes to a darker windows theme at 18.00 and back again at 6.00. But if the computer is turned off and on, it might not be the correct theme.
2) There is a little download able program PangoBright which makes the display dim. But is it possible to use Intel Profile and change it with task scheduler instead? Any guide to that? The profile just have to reduce brightness to about 60% during night.
