[SOLVED] Dual monitors no mouse on second screen.

I just installed a new (used) GPU and now cannot move mouse to second screen.

Titan X GTX 12GB card. Monitors same make and model. ( Worked fine on prior GPU )

Second monitor has taskbar but no desktop icons. If I open programs that previously had panes on each monitor they return to original position as expected but cannot mouse over to access the program.

When I open the display settings window it opens on the monitor without a mouse so I cannot drag displays around without a mouse. I can tab through settings but nothing there solves anything. If I try "detect" is says no second monitor found however in advance settings it clearly shows and correctly identifies both monitors.

Win 10 | 10.0.19043

Could this be driver related or is it a Win 10 problem with dual monitors?



It would be easier to work on this if I knew of a way to move the settings screen to the active monitor screen.

Any ideas?

[SOLVED]

Solved by experimenting. First task was to get the settings window on a screen with a mouse. I tabbed down to "Make this my default" and then had a mouse on same monitor as settings window.

I checked the monitors. All okay. Same make, model and resolution etc. Still no mouse on #2

So tried changing resolution to lower seeing and got a mouse back on #2 but that screen was compressed in size ( blank borders appeared)

I then changed resolution back to the original size and then everything was fine. Both monitors full screen and mouse now works as it should.

Guess Win 10 was taking a nap..got confused.

Thanks ya'all
