My sugestion is to create a profile "exe" , "ini"?
How its will look?
When (in my situation) i off the Aster and set my screen correct play some games etc...
and when i try back to Aster he dont want work properly always
Issue :
1) Problem with screens (dont want start) i suppose its somethink with nvidia drivers becaouse when i do somethink with screen inside windows its can start working but i still dont figureout what is correct settings for that
2) Some devices need to be attach again - its anoing
3) Some time i make difrent configuration (depend how many user want to use Aster )
So i think best idea will be create a profiles which user will be abble to set
and the windows and Aster will remember how was they look
so its should dont make any problem again with on/off and switching devices
im not sure its possible with programing aster becaouse its came with GPU Driver.. but im sure you are smart Guys

Why Turn off The Aster?
Some Games got extra 1-5% FPS and i can play them Full screen without problem
save 1-5% (depend HDD-SHDD-SSD) of my Drive
Save 1-5% (depend of CPU) of my CPU
Save 1-5% (depend of GPU) of my Memory GPU
Even with my GTX1080 the 4K gaming need all that %
