Does it happen only while on battery? If so, try the following:
Right click on desktop > Graphics properties > Display > Set Refresh Rate to 60p Hz
Power > Power Source: On battery > Uncheck Display Refresh Rate Switching.
The reason why you ran into this is probably that Windows automatically installed a generic display driver.
Unchecking the "Display Refresh Rate Switching" checkbox that HUMAN1111 described resolved this issue with Windows 10.
