For on-board graphics adapters, you increase the amount of video memory by going into the BIOS Setup. To get into BIOS Setup, press F2 at the HP splash-screen.

Be aware that the graphics adapter uses system RAM, so the more memory you assign to the graphics adapter, the less memory will be available to Windows & applications.
