Strobelight - LightBoost Utility for AMD/ATI and NVIDIA

[LaUs3r]

hey guys,

today I just got my new XL2720T and was quite eager to try Lightboost.
Unfortunately I can not switch off lightboost via shortcut "ctrl alt -" In fact, nothing happens and the green light for nvidia vision keeps on shining. Even if I try to turn off lightboost via the menu it doesn't work.
I tried to reset the settings, added new strobed and not strobed refresh rates, updated the nvidia driver, etc. - nothing worked so far.

what I find confusing is the fact that I only can choose refresh rates (not strobed) which do not match exactly the monitor's specs, like 121Hz, 101Hz.

So, any hint on that?

thx in advance
