Need Help Fixing This Onbaord GPU issue

Hello everyone i have Asus Maximus VII Ranger Motherboard with 4670K CPU the motherboard has the HDMI port also.
In PC there are 2 GPU one is GTX 1060 and other is 1070ti in which i am mining on the monitor HDMI cable is plugged in the 1060 but while mining i cant use the system properly not able to watch HD videos or Movies
so what i did is i used my onboard GPU
1st i tried with the HDMI it was not working
2nd i tried the VGA cable it was also not working
then i changed the display settings in BIOS to CPU VGA i got the display but i was not able to see my desktop icons or mouse cursor i took the screenshot and rebooted the system plugged the cable on GPU again
checked the screenshot and noticed it was on DUAL screen how can i fix that?
single monitor only using onbaord display?

Solution
That is because Windows thought you got 2 screens running. With your monitor connected to motherboard, press Win+P few times until you get your icons back on screen (that will be last setting - 'second screen only').
