3 Monitor Setup Problem

[therealmarky4u]

I just bought a new monitor LG 34um95-p. But i use to have 2 24 inches asus monitors. so when i plugged the lg monitor worked fine, but everytime the computer sleeps or reboot it messes the display, the LG woud show an "Out of Range" signal, then even if i reboot the problem would exist. the only fix is to everytime uninstall the driver for my videocard and reinstall it again.
LG 34um95-p i put 3440x1440 (as recommended) this is the main display #1. the two asus 24 inch monitors they have 1980x1080 resolutions. The thing is if i only use the LG 34um95-p 32 inch monitor, I don't get problems, or if i use the two asus monitors I don't get problems too. The time i get problems is if i try combining monitors with the LG 34um95-p. Any Help please

MY PC:
i7 six core
evga nvidia gtx 980
32G RAM - 8x4G 2400mhz
mobo - asus rampage v extreme

How are you connecting it? DisplayPort?

How are you connecting it? DisplayPort?

The LG LG 34um95-p is through Displayport, one Asus is through DisplayPort too, and the other one is from DisplayPort to HDMI ((Monitor). I'm thinking do I need a second graphics card? Or there is a fix fo this problem?
