Well thought I had the system sorted. However, the laptop insists on using the onboard intel graphics rather than the nvidia gt640M graphics card that came installed on the laptop. I have just restored the system to factory default, but still have the same problem. Please help.
Having read some more, I am not sure that is the problem. The computer spec say the max resolution is 1600X900, but dues to the size of the monitor (17 inch) windows 8 say the resolution should be higher. Looking at the screen the picture quality is poor and you can see vertical lines where the picture is made up. Any ideas? I have update the driver for the intel onboard graphics.
