  • Hi,

    Please try to reinstall your graphics driver and check the result in Device manager.

    Also, check if you get the latest firmware installed on your tablet.

  • * Open the Control Panel, click on Device Manager.
    * Double-click the Display Adapters to expand the item.
    * You should see that the graphics card installed on system is listing there, like Intel HD Graphics 4000. Right-click or hold and press on it and select “Properties” from the pop-up menu.
    * Go to the Driver tab, click or tap the “Update driver” button.
    * Manually select “Browse my computer for driver software” option > Let me pick from a list of device drivers on my computer link at the bottom.
    * Choose “Microsoft Basic Display Adapter” from the list, and apply it.
