Remember enabling VRR or PureXP (or selecting certain profiles) will disable some picture adjustments. You can try turning FreeSync OFF in monitor, and turn GSYNC OFF in NVIDIA Control Panel, and select one of the custom profiles, to get access to more adjustmentsilluwa wrote: ↑04 May 2022, 21:45Hi, I just wanted to post an update on this. Monitor still has been unable to adjust a majority of the settings, with the brightness seemingly shifting by itself when in use. No fixes seen to work even after trying to reset every part of the monitor that I can find. Something seems tangled up on the software end of my PC, because it functions fine when plugged into my laptop. Sorry to ask again, I might have to just reach out to Viewsonic and see if they have a solution.Chief Blur Buster wrote: ↑25 Apr 2022, 15:58It's an out-of-bounds exception error -- thank you for reporting this.
This is caused by DDC values being out of range.
TEMPORARY FIX OPTIONS
(A) To fix this, run Entech SoftMCCS and reset the extended DDC values back to 0, before reloading ViewSonic Strobe Utility;
-or-
(B) Another workaround is to temporarily edit ViewSonicStrobeUtility.ini and set maximum value to 255. Once done, launch, slide all values to 0, exit, and restore the old copy of ViewSonicStrobeUtility.ini. It will then function normally again.
This is already fixed in the next version of Strobe Utility. Out-of-range DDC values sometimes occur after a monitor firmware upgrade or a factory reset -- this creates the conditions to crash ViewSonic Strobe Utility.

If your problem is that the settings grays out randomly enables/disables erratically to no pattern, it may be automatic mode switching that is happening more often on one computer:
Remember that things like:
- Switching refresh rates
- Switching GSYNC on/off all the time (common problem: GSYNC=OFF in Windows, GSYNC=ON in games)
- Switching resolutions
- Switching ports (different port on GPU or different port on monitor)
Can activate a different picture settings profile on some monitors, which can confuse things. Different GPUs (e.g. AMD versus NVIDIA) can do more switching than usual.
To try to calm the settings-switching down:
- Always use the same GSYNC setting (on or off) in all apps (Windowed and fullscreen).
- Always use the same refresh rate in all apps
- Always use the same resolution in all apps
- Always use the same ToastyX setting in all apps (if you use QFT tricks)
- Don't keep switching multimonitor settings
- Don't keep switching ports on either GPU or monitor
You can start afresh by resetting your driver settings / reinstalling drivers / uninstalling ToastyX settings (reset-all.exe).
If you need more flexibility, you can also try modifying a custom profile and selecting that custom profile.
Most of the time it's not a problem as you should have less hassle, but hopefully this helps you narrow down a computer-specific problem because graphics drivers are sometimes capable of automatically changing a setting (e.g. GSYNC=ON) that automatically disables certain picture settings.
