It is the legion 5 15IAX10 with the 5070 and the intel i7 255hx. Its freedos too. I never set up my own pc before so I really dont know what to do. I downloaded windows 10 on it with a fresh installation media via usb drive. But the mouse sensivity feels weird and the background is not full in frame. Is the oled aspect ratio messing with the screen ? Also the mouse sensivity seems alot lower than my own pc even if I plug in the same mouse. Can someone tell me what to do step by step from the start ? I think I will uninstall win10 and redo it. Also are the new drivers compatible with win10 ?
