    displayport-hdmi wont work unless its an active adapter, i had the same problem i got a mini dp to hdmi and it will see it as hdmi so you will have 2 hdmi's connected so you need to get an active adapter.
  6. Okay, thank to all of your suggest, i will get active adapter tomorrow or by end of week. If it didn't work, i need other solutions. And question to Kapitalistas, all 3 monitor is 1920x1080, i dont see any wrong with that, my computer know third is here, but it wont let me connect, as if two is limited, but i know that my GPU allowed more than 3.
  7. did all 3 supports same resolution.
  8. All eyefinity/NVsurround cards,besides Sapphire "FleX" cards, only generate two clocks that sync with the monitors.
    DisplayPort uses a separate digital signal and that is what allows 3+ monitors.
  9. Problem have been solved, Thank you for all of your help, as Crispychips and vampyiere6 said, it need Active adapter :)
    Thank you all for your time.
    And, yes Kapitalistas, they to have same resolutions
