    So I have a windows 8 PC. Switched from a Mac. This PC came with nvidia graphics, but it can only read the integrated intel graphics. How do I get it to show the nvidia graphics?

    Type dxdiag and run the program to verify your PC having the Nvidia Card.

    Nope, doesn't show. Only the intel hd graphics 4000. But I'm positive this PC comes with nvidia GeForce 640.

    click windows then run then msinfo32 and then go to display and see if the nvidia shows up. I have a dell xps that comes with a 420 nvidia

    Silly question perhaps - have you installed the drivers for it? The driver right now on that screenshot looks awfully "look what Windows found for me".
    This should be the latest if you're using 64-bit Windows 8:

    OP - is that running on a laptop? Am guessing Sony Vaio

    Just wondering because the intel 4000 will use a lot less power and has more dedicated RAM than if you force it to use the nvidia 640M LE on its own.

    The way it should work is the nvidia card will automatically step in to fill the gaps that the intel hd cant handle. The only thing that will happen if you force everything through the nvidia is increased battery drain with no real performance enhancements.

    No, a vizio ca27t-a5 all in one.

    I did, look what happened. So annoying. Look at "About Your GPU" and "NVIDIA Installer". Click image for larger version.

    Perhaps a call to customer support maybe the best thing to do.

    Go to Nvidia and see if there are any updated drivers. You might need to uninstall everything Nvidia then proceed.

    You mean fix? Well I contacted vizio like someone here said and there was a setting to leave nvidia graphics always on, so I enabled that.

    Your laptop got Optimus Technology. Basically its going to use the integrated graphics card to save power then switch to dedicated when you need it e.g. when you open graphic extensive application like games. if you're going to enable it always, that will shorten your battery life.
