no video output with hdmi or display port, only with DVI cable

i know this is a dumb question. i just built my computer and i have a ge force gtx 770 mated to an asus deluxe z87 mobo. my monitor is a an asus 23 inch. i can get video output using the old DVI connector but i cannot get video output using the HDMI or Display Port connectors. what am i missing here? do i need to go into my bios and set something up so i get video output specifically from the hdmi or display port. i thought i would get video output from whatever cable i connected by default. any suggestions or help would be much appreciated.

  1. It really should just work.

    Do you have another monitor to test the card's HDMI and DisplayPorts?

    your right you should get it from any port unless your trying to push > 60Hz, then only video output on the DP ports should work for that (HDMI / DVI don't support those). Personally it sounds like the monitor isn't working, have you tried from your computer via HDMI you know works (say your Blu-Ray or something) and then to your TV?
