Larry has a Lenovo Yoga 720 convertible laptop, but when he plugs it into a dock, it doesn't show the bottom part of the screen. However, when he uses it in tablet mode, it's fine. Leo suspects that the monitor driver for the computer monitor is wrong. If it's using a generic driver, it won't show the whole screen. In this case, go to the monitor's website and download the latest drivers. Also, look in the monitor settings for "under scan" and enable that.
