There is only a DVI-D and VGA port on the integrated video. Therefore, you would have to buy a video card that would support three monitors. Once the video card is installed the integrated video is not available. Newer video cards require UEFI in the motherboard instead of a Legacy/standard BIOS. HP didn't begin using UEFI until mid-October, 2012. Your BIOS can't be upgraded to UEFI. Your best option is to choose a manufacturer and contact their Tech Support for help with choosing the best card for your needs.
Another option that you can consider is a USB 2.0 video adapter. If this sounds like a good option, I suggest contacting StarTech's Tech Support for help. I normally use their Chat Live option. They have always been very helpful.
