See if your DVI connection has analog signals. It's a 2 or so buck adapter if that VGA connection is dead.
Hi Just bought a second hand Lenovo k450, the VGA (blue) connector not working. The previous owner used HDMI connection and it works because I saw it. There is a GForce card install but the connector shape is different I guess it is DVI. I do not know how to solve it any ideas are welcome.
