monitor + lcd tv / same PC

[sioux]

I connected a monitor and an lcd tv to the same PC.
The monitor is connected with DVI - HDMI and the lcd tv is connected HDMI - HDMI
When i want to watch a movie, i change to lcd tv, no problem so far.
I'm using Windows 7 Ultimate x64 / GTX 660 Gigabyte OC / BenQ GW2760HS /
LG32LK430 ( lcd tv )

I attached here 2 images. One is with the BenQ settings in Nvidia Control panel and the second one is with the LG tv.
My question is : how could i modify the settings for LG tv ( brightness / digital vibrance, etc ) without affecting the settings for the monitor ?
As you can see, when i click on the LG, i cannot modify anything ( use Nvidia settings )
Would you help me, please ? I want to have a different value on Digital vibrance, for monitor i keep it to 100 %, and for the lcd tv i wish i could keep it to 75 %.
Thanks in advance.

So, is not possible to have different values in Nvidia Control Panel, for the two displays ?
