Hackintosh 3 monitors with Quadro P620 / main monitor boot up and then no signal

Hi all,

I would like to seek for your help to advise on how to fix this issue.

​

Issue: when boot up, the main screen displays the Clover, and then finishing booting: main monitor "no signal", other 2 monitors have signal as normal. In order to get the main monitor working, I need to turn off and turn on the main monitor.

Graphic: Quadro P620

CPU: Intel I5-4570

OS: High Sierra

Monitors: 3 Dell U2414H connects via DP port
