Acer 5733z

Hello,
i just bought a new Acer 5733Z,
1).the display was not satisfying.
2).The image quality is poor.
3).when i try to play a Solitaire, "Hardware acceleration is either disabled or not supported by you video card driver"
4).Image on the home-screen are distorted.

What should i do.?
I try downloading the video driver but i don't find it.;(
