Can't get third monitor working on Mojave

I have triple monitor (DP, HDMI, DVI) , so far could only get 2 monitor(HDMI, DP) working. I've tried change smbios from iMac17,1 to iMac14,2 to MacPro6,1 but it didn't work. The funny thing is when I unplug my 2nd monitor (DP) and replug 3rd monitor (DVI), the third monitor become my 2nd monitor. It seems it could only handle 2 monitors. Before Mojave I was on Sierra with three monitors working seamlessly. Do you know any solution to this?
