Dual Montiors - 2 computers- SFF/MFF

If possible Id like to run dual monitors with running 2 computers, 1 keyboard, 1 mouse.

Having never used dual monitors im unsure what i need to make this happen.

The Specs/Ports on computer(s) & the Specs/Ports on monitors needed to make this work.

Other hardware.

Cables Needed.

The following is what id like to do, if it all possible.

2 computers - (CompA) = win10 (opti7070 SFF) - (CompB)= win11(opti7010 MFF)

1 Keyboard / 1 Mouse total  (shared between the two computers)

Dual Monitors

  Monitors would function as such if possible.

 Using (CompA) both screens user would be able to view if needed/wanted to.

 If (CompB) is 'On' then one screen (CompA) one screen (CompB). Ability to use CompA or CompB

(would the keyboard/mouse then switch back and forth between computers when the mouse is moved from one

screen to the other to use either CompA or CompB?)

An easy way to make it work so to speak without crawling around swamping cables

back and forth or trying to find a button to press under a desk or under paperwork.

As far as a printer goes im either going to have to share a printer between the two, or (CompB) will

have its own printer. (id rather not do wireless if possible)

To further complicate the matter, and looking ahead, maybe a way to easily plug in a laptop down

road to use with one of the monitors when connected, then using the desktops keyboard and mouse

instead of the laptop keyboard/mouse.

Hope this all makes sense and is possible.

Thanks for the Help.
