Dual monitor / External monitor / Multi Monitor setup issues

I have came upon a sudden and a restless problem only when more then one monitor is plugged in. I have two monitors LG 32" and Philips 27" both DisplayPort. When my computer boots up inside login screen first monitors screen starts blinking. The second monitor is black but blinking trying to connect. fter some time the second monitor goes offline or like in few casses it sorts itself out and the monitors work. If i unplug and plug back the cables bunch of times i can resolve.

In the issue was resolved by installing RDM
Then tinkering with both displays resolution and refresh rate the problem was solved and blinking/trying to connect stopped. Maybe he needed a saved configuration for the monitors. I’m not sure anymore. I’m glad if this helped you.

To switch to another patch search for mtrr_update_action in config.plist. Then set Enabled to true for patch which you want to use. Remember to set Enabled to false for second PAT patch.
Don’t try to use them both at the same time, it won’t work.
