Strobelight - LightBoost Utility for AMD/ATI and NVIDIA

[ToastyX]

There's no way for Windows 8.1 to cause what you described. If the program starts without any errors, then LightBoost is unlocked. The only other thing that could go wrong is the proper resolution is not being set, in which case the monitor wouldn't be in 3D mode and the colors shouldn't change.

If the monitor's menu shows 3D mode, there shouldn't be any motion blur. If you're seeing a double image effect, that would indicate a frame rate issue and not a problem with the strobing.

You should see a strobing effect if you wave your finger in front of the screen. If the monitor is in 3D mode but it's not strobing, then something weird is going on.
