In order to use this driver you have to disable the unsigned driver enforcement which is by default active in windows 8 and then install the driver:īlimey - I had completely given up on getting the HDMI to work on my vgn-z51xg. Please be sure to download the right driver for the system: for the VGN-Z with 9300M card are the one made by Andrew08 (to which we are all grateful) named ' 26308 2020 101112'.īefore starting the 'Stamina - Speed' switch should be set on Speed.

In this short post I'll show how to set up only the graphic card both on Windows 8 and 8.1 to help you be up and running without wasting time.įor further details and to find the drivers please refer to this thread which solved all my problems. You can always leave the nVidia card unrecognized and default to the Intel integrated drivers pre installed by Windows but this Notebook is a bit outdated and maybe you want to use it at 'full power' to keep it a bit longer. Sony made the drivers for Windows 7 (32/64 bit) and most of them work fine except the video card one. Unfortunately this notebook came with Windows Vista Professional preinstalled and when Windows 8 came out I choose to update the OS to get rid of it. It's a Notebook with an Hybrid graphic (intel integrated + nVidia 9300M discrete)

I bought my Vaio VGN-Z650 notebook on April 2009.
