Installed XP Pro tryed several grahic drivers none work

Hi i have recently installed Microsoft Windows XP Pro and tryed several graphic drivers which are listed under my laptop driver section but none allow me to get the correct resolution,

When i try and edit the resolution i only have two option, 1 option is to big for my screen and the other option is almost perfect but still slighlty to big,

My model number of my laptop is:

Acer 5536 and i would appriciate any help for locating my specific graphic driver,

Regards Paul

Problem solved i downloaded and installed driver genius,

I used to hate this program but looks like the new edition is better,

Regards Paul
