    I have that same monitor. the problem for me was the mini displayport on my r9295x2.
    Xfx had to send me a whole new card.
    The other thing you can try are the best DP cables you can buy. Gold plated, best reviews, etc. You might have to try 2 or 3 different brands of cable.
    If that dosent work then you'll have to RMA the monitor. If that still dosent work than its the DP ports on your 980.
    I went through this with the PB287Q. I RMA the monitor, waited 4 weeks to get it back and.......same problem. RMAD the 295x2 and turns out all 4 mini displayport were dead on the card.
    Total of 6 weeks of frustration to find the source of the no displayport error.
    so it's iether the cable, the monitor, or the card.
    Good luck......

    yes, i installed the last driver but it doesn't work!. i think the cables are ok beacause when i change the HDMI with DP when the system is on, it works but after shut down or reboot it doesn't work again.

    Have you tried rolling back the nVidia driver and see if that works?

    yeah, it doesn't work when i press the start button. i think my graphic card is not compatible with 4k monitor by displyport beacause i test 770 g.card and it works good.

    I'm having a similar problem. My board is Maximus VII Hero with 4.7.2015 bios update. XFX r295X2 video card. Power supply Antec PRO 1200. I can't see anything when booting pc. Windows loads because I hear the Windows welcome jingle. I can even shut it down with my preconfigured shutdown key combination shortcut command. Any suggestions?

    When I put back my AMD 6990, everything shows on my monitor and is ok. This is my 2nd card and still same problem.
    I've picked up a Corsair 1500i. If this fixes my problem, I'll post results.

    Hi Ashiphone6

    I have a Asus Radeon R9 280X DC2 3GD5 V2.

    It has 2x DVI ports and 4x Display Ports. It has a hub built into the card.

    I tried to use just the Display Ports for my 3 Monitors, but it just did not seem to work. So after some lengthy reading on that tech, I found that I should use a DVI port first, and then use the DP's as 2nd, 3rd, 4th etc.

    I suppose it depends on the card and what ports or converters you may have. DVI and HDMI are similar creatures.

    Does your AMD card only have mini-DisplayPort outputs? If so, make sure your mDP-to-DP cables are passive/direct signal connectors (not active signal converters) and that they're actually DisplayPort 1.2 certified. I've used these before and they work perfectly, while I've used others (including the free cables XFX provided with my old AMD cards) and they did not work (prompting me to buy the ones which did, lol). There's a lot of uncertified and underspec DP cables on the market, and many people report a bewildering array of problems from using them (then again, many people also report that everything seems to work just fine) - I just think it's worth paying an extra $2 to be certain, lol.
