I installed version 311.83 and the issue still exists. In fact the issues exists in every version I've tried.
To reproduce simply perform the following actions:
Open the "NVIDIA Control Panel"
Display -> Adjust desktop colour settings
Use NVIDIA settings
Brightness 0%
Contrast 0%
Gamma 0.50%
Digital vibrance 15%
Apply
Use power button to Shutdown
Use power button to Start
Screen contrast changes from high contrast to lower contrast then high contrast.
Would someone in ASUS support please respond as soon as possible as to why this is happening ?

Anyone still having this issue? I've been tracking it down and I found a solution that works for me and has not been covered in this thread.
The issue is the power setting for "Adaptive backlight" (*different than "Adaptive brightness"*) which is handled by the NVIDIA driver. For some reason, the GUI to configure this option doesn't always show up in the Windows Power Options. You can do it in the registry.
First, if you are having the issue, try changing your power profile to "High performance" and see if it goes away. The default settings are that you will see this issue always if you are on the "Power saver" profile, on battery only if you are on the "Balanced" profile, and you shouldn't see it at all on the "High performance" profile.
If you want to use the "Balanced" or "Power saver" profile (or a custom profile), you need to make a registry change to get this issue to go away.
Four steps.
1. Search the registry for "aded5e82-b909-4619-9949-f5d71dac0bcc". If you see a key with this name under HKLM\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes, see if you have values for "ACSettingIndex" and "DCSettingIndex" under this key. If you do, set them to 0 if they are not already set.
2. Navigate in regedit to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings". Go through each of the keys here and see if you have a subkey named "aded5e82-b909-4619-9949-f5d71dac0bcc". If you find it, drill down to "DefaultPowerSchemeValues", and under each key there, set the "ACSettingIndex" and "DCSettingIndex" to 0.
This registry snippet will set the appropriate values for the default "High performance", "Balanced", and "Power saver" plans, and may help you find the appropriate values to change if you are having trouble following my previous statements. 🙂
[Edit] Not sure if my quote worked, it looks like the board added some extra spaces in the word "Control". You should probably track this down manually.
3. Reboot, I guess, to make sure the changes take effect.
4. Profit!

WOW, I followed these steps and it worked .. for the most part! I seem to be getting some slight contrast changes still, but it's not NEARLY as bad or noticeable as it was previously, and it could just be my eyes .. hard to break a bad habit.
I registered for the forums just to say thank you, Aaron! You've saved my sanity.
