Windows 10: Windows 10 Zoomed Screen

After I installed my Windows 10 PRO free copy my screen looks fine but i noticed when I play my game my FPS dropped to 10 investigated it a little bit then I discovered that my primary display adapter is the on-board display adapter. I installed my main adapter which is the NVIDIA driver, my fps went normal again but my screen zoomed my resolution is normal*1920x1080*. Help

How do I turn off touch pad zoom?

Can not turn off Zoom on my touch laptop with Windows 10. Unchecked all zoom options in Synaptics--didn't work. Deleted Synaptics program leaving Microsoft touch----no options to get rid of Zoom. Screen haphazardly zooms in and out when using touch pad
and touch screen.

See this same problem from many other Win 10 users,
