Dell Vostro 8400M - Waking from Sleep, Screen save, Digital Vibrance Reset

[Guest student1]

Hi,

My Dell Vostro 1400 with Nvidia 8400M came with default drivers that were unable to adjust the digital vibrance.

I installed the Release 163.11 release drivers and I was able to adjust digital vibrance. However, everytime my laptop wakes up from sleep or some sort of auto-screen off (I use Vista), the Nvidia Digital Vibrance is reset to 0. I have to open up the Nvidia control panel, and click on the digital vibrance adjustment button to reset it. The actual "slider value" of the Digital Vibrance is remembered, but the actual amount of Digital Vibrance applied is reset to 0. The slider stays at the number I previously set, but I have to click on the slider to effectively reset it.

How can I fix this?

Thanks alot!
