CPU: Intel i7-2600 @ 3.40GHz
RAM: 16.0 GB
GFX: EVGA GeForce GTX 970 FTW
Drive config: 256 SSD boot drive, 1 TB 7200RPM HDD, 1.5 TB 7200RPM HDD
OS: Win10 Prof
Monitors: Samsung UN40JU6400F, ASUS VE247, DELL ST2220T

My problem: I used to have a Seiki 50" 4k TV for my monitor. It did not have HDMI 2.0 so I ran it at 1080p/120hz. Today, I replaced it with the Samsung TV, and as of this moment, have it running at 4k/60hz. The trouble is when I enable my other two monitors, any of them, it drops to 30hz. Am I missing a setting? Does my graphics card not have enough power to handle three displays when one of them at 4k/60hz?

Thank you for your time.

    Are you running on Display port, HDMI or DVI?
     
    I think Display port is the only one that will fully support 60 Hz refresh
     
    HDMI 1.2 will only support 30Hz refresh and 1.4 supports 60Hz with the proper cable if I remember correctly

    The 970 has an HDMI 2.0. By itself I get the 60hz at 4k, it's just that when I add any second display (through hdmi adapters on the DVI ports), it forces the 4k display down to 30hz from 60.

    Might want to give evga tech support a call to see what they have to say about this issue. https://www.evga.com/about/contactus/
