Now come this questions, so I can understand how this is working.
Is RAMP1 set to the current gamma when the form loads?
RAMP2 is then supposed to be a change from RAMP1 (darker)?
Stepping though I see that lVal is always 0, so it RAMP2's values will always be 0
Ramp1(0,0) is supposed to store the current gamma settings
Ramp2 is supposed to be the changed value

My Ramp1 is also all 0's ( even with my previous example ), so I still think the whole problem is that the initial call to GetDeviceGammaRamp doesn't somehow succeed in storing the actual values inside Ramp1.

If so, then try to e.cancel=true, if e.windowsshutdown is not true.
Then also environment.exit(0) after to manually exit the cancelled exit.

If the api are declared the same I think it will work, unless you do have a stubborn monitor ofcourse. lol
Initially I did use the Closing event, but changed over to Closed.

I really do think my monitor is as stubborn as me, afterall, I feel like I'm the monitor's dad LOL! simple thing
