Found your Lenovo Support page for your laptop. It has a very new BIOS (1/2018) and last VGA Driver for AMD and Intel Graphics was from 9/2017. Here a copy from the Lenovo Support Page: laptops and netbooks :: 700 series :: 720 15ikb type 81c7 Lenovo PC Support :
AMD recommends using the graphics drivers provided by your notebook's manufacturer as the manufacturer has customize the drivers to support the built-in display and the features and functions specific to the notebook. Customized graphics drivers are available for download from most notebook manufacturer's web site.
If the current operating system is not the version originally installed on the notebook it may not meet all requirements and compatible graphics drivers may not be available. Please refer to the notebook manufacturer for supported operating systems and drivers.
AMD provides a reference/generic graphics driver for AMD Mobility Radeon graphics with limited support for notebook specific features and functions. This is not intended to be used as a replacement for the notebook manufacturer's driver
** Windows 7 and Windows 8.1 must be fully updated before attempting to install any AMD driver. All 'critical', 'recommended', and 'optional' (no language packs,etc) updates as well as any Service Packs (SP) must be installed before any attempt to install graphics drivers. If you do not get this message .... keep installing until you do:
