JoelTG, could you please attach the DX Ddiag report from your system so I can check the current information?

Dxdiag Report: Type dxdiag in Start Menu> open> Save> Attach using Advanced Editor Options.

Hi there,

Thanks you for trying to help me, I have attached the file you requested to this post.

JoelTG, since your system has Switchable Graphics it is important to find out on BIOS which is the primary Video port. Sometimes when using a single monitor and if the video card was set as primary video source, the monitor needs to be connected to it.

I will also recommend you to install the graphics drivers again. On a system with switchable graphics it is necessary to install the Intel graphics drivers first and then Nvidia's.

This link will take you to the latest Intel drivers available for the HD4600
