4 pin argb strip not working

I have this weird 4 pin argb strip and with some testing i think that it has two grounds for some reason?
I can get it working with an arduino (with only 3 pins connected) but when I try to control it with my pc signalrgb (or any other program) doesn’t work.
immediately after I connect the strip the first light turns on in a dim blue and that’s it.
Any idea on how to control it/properly connect it?

4 pin isn’t argb, it is not addressable like a 3 pin. It’s a 12v analog connection. One pin is 12v, another is red, another is green, another is blue. Do not try and connect a 5v argb to this header.

I know that
But it is addressable. I can control each led individually with an arduino
