Help with three Monitor issue

Hey guys. I am currently trying to set up a three display configuration and am currently having a hard time. Here are the specs for my computer. It is an HP:

HP ENVY h8-1420t Desktop PC
• Windows 8 Pro 64
• 3rd Generation Intel(R) Core(TM) i7-3770K quad-core processor [3.5GHz, 8MB Shared Cache]
• 8GB DDR3-1333MHz SDRAM [2 DIMMs]
• 1TB 7200 rpm SATA hard drive
• No secondary hard drive
• 1GB AMD Radeon HD 7670 [DVI, DP, HDMI, VGA adapter]
• 460W Power supply
• SuperMulti DVD Burner
• Wireless-N LAN card (1x1)
• 15-in-1 memory card reader, 2 USB 2.0 (front), 2 USB 3.0 (top)
• No Additional Office Software
• No additional Security Software
• No TV Tuner
• Beats Audio (tm) -- integrated studio quality sound
• HP wireless keyboard and mouse with Win 8 keyboard
• Adobe Premiere Elements & Photoshop Elements 10

As for the monitors, they all have DVI, DSUB, an HDMI ports. I have attached two of the monitors without any trouble via the DVI and HDMI ports on the computer. However, I am unable to get the DP port to work. I bought a DVI to DP adapter that did not display anything on the monitor. I have been reading around that I may have purchased the wrong kind or it simply does not work. I am wondering if getting a VGA to DP adapter would work instead.

If you guys could help me, I would very much appreciate it. I am very lost right now.

  1. you have to use the dp for the third monitor, here are the approved adapters. http://support.amd.com/us/eyefinity/Pages/eyefinity-dongles.aspx

    i like using dp to vga adapters.
  2. And the VGA isn't an option? Because you say your monitors have VGA/DSUB. I'm still using that and even with higher resolution, the quality is okay for a "side-monitor".

    There is no port on the computer. That is the problem I am having. From at least I could see.

    I am going to look at that list. Thank you. I wonder if the micro center will have those in stock.

    Sorry, my fault! From my experience, a dp-to-hdmi-adapter should work.
