NEED HELP with new software for Graphics Card.

I have an 8600M GT 256 MB on my laptop, and when I connect it to my TV via HDMI(and it never fits perfectly), there isn't this one option in the nVIDIA control panel to adjust screen size(HELP says it should be there), so I decided to get this new driver that improves it.

However, it won't let me install it for laptops, it says to get new software for graphics cards, it must be from the laptop company itself. So I went to Acer to get it, but they were giving the same software version of the one I already had, and I didn't want to redownload it because then it would reset everything and wouldn't change anything. So is my laptop so futuristic that there hasn't been software released yet? How can I improve my current control panel/graphics card?
