Check the settings of your laptop, if your graphics card is Intel then you should have no problem. No need to install the drivers of a projector as they got none. Righ click on any place of your desktop and then check if you got something like Graphics Options and from there put the output as Clone [laptop+another screen which would be your projector in this case].

If not then you have to go the advanced feature of your graphics cards and set it from there. To access this, right click into any place of your desktop, then properties then choose settings from the above tabs, then click advanced. You will see many multiple tabs, you should see something saying:Intel graphics media accelerator and from there you can click Graphic Options then change it to the desire output.

Best Regards
