Hopefully someone can help with this query as I don't know very much about graphics cards. I've connected an external 19inch monitor to my Sony laptop which the graphics driver (Mobile Intel 965 Express Chipset v126.96.36.1995) can support with a maximum resolution of 1440 x 900. However I now want to upgrade to a larger 23 inch screen with a 1920 x1080 resolution. Basically I'm not sure if the drivers capability is determined by the specification of external equipment connected to it, so need to know if I have to upgrade the graphics card as well. Any assistance would be appreciated.
