Windows 10: how do i connect my all in ones built in display to dedicated graphics

i have the hp envy all in one desktop 34 c0xxx and it says its display connected to the integrated graphics. i have a secondary monitor that is connected to the RTX 3060 laptop that is in the All in one. i tried disabling the integrated graphics but that just turns off the built in display. is there anyway i can connect the main display to the RTX 3060? i also changed the graphics in nvidia control panel but its still connected to the built in graphics.

Dedicated graphic card display improperly.

I bought new PC and connect my graphic card (GTX 1060) to HDMI port of my monitor. I also connect VGA ports of monitor and motherboard. The problem is the graphic card cannot display desktop icons, applications...... The screenshot I took show 2 desktops: normal one of Intel HD 530 and blank desktop of GTX 1060.



Another thing is there is no option for "Preferred graphic processor" in NVIDIA Control Panel so I cannot use it to play video games:

 

Regarding Dedicated graphics

Sir please clear my confusion

• There is a program called DXDIAG when i open it and click on display it shows graphic memory 2136 mb but when i open intel graphic properties it shows dedicated video memory 128 mb so where all the left memory used.
• Is updating driver really helpful especially graphic drivers.
• How to increase dedicated memory from 128 to 512 because mylaptop contain 4 gb ram.
• When i enter BIOS i do not locate configuration tab what to do,help me to provide the advance bios mode

 

Dedicated graphic card display improperly.

I only use 1 monitor. I am connect to both ports because my GTX 1060 does not display properly. When I try to solve the problem, I switch between HDMI and VGA input to check if the GTX 1060 display the same as onboard Intel Graphics.

The screenshot below show 2 displays of 2 cards: the left one is Intel Graphics 530, the right one is GTX 1060. I open Firefox window but the GTX does not show any window of Firefox, only the taskbar. Even the taskbar is not the same.
