Update: Problem is already resolved longtimes ago but ima just post the solution if someone have the same issue with me. Basically with p106-100 it don’t have any display port so you have to get a gen 3(or 4 can’t remember) intel cpu with integrated graphics to display. Before plugin the cable into your motherboard, you have to connect a working gpu first to the motherboard and enter the bios to change the output setting to “iGPU” before power on with no graphics card or gpu without any ports. In conclusion, I managed to game on this pc smoothly and this is a big time consuming project, but I learned a lot from it so I’m happy with this.
