You have to install the latest drivers for your video card, if it is onboard graphics then the best bet is to look up the model number on the motherboard and do a drivers search for it.



If it is an Nvidia or ATI graphics card go on there website and download their latest drivers.



With them installed you should then be able to change the resolution without further hassle
if Ur screen is 17p,press the right button of the mouse,choose,propritites then settings,after that press advanced,at the first page U can change the ';dpi';(general) and at (Adapter) U will find the resolution by clicking on (list all modes)then choose what U want,have a nice day
