Looking for universal display. And change set on controller

[Shalom_hadad]

Hi. I purchase new controller. But doesn't have display port. I want display so need universal display. Connect to phase wire.. Have something good?
Found 1 in AliExpress but doesn't have buttons or settings. So if its fake cant fix it. Need something better..

And controller set to 42v low Protection. Can disable it or change?

Thanks
