Windows 10: Dual monitor problems

I have dual monitors and it has been working perfectly fine until a week ago. Whenever I play a game and I try to click on my second monitor, my screen glitches for a second and whatever I clicked on my second screen moves to my main display. For example I'm playing NBA 2k22 on my main display and I have discord on my second monitor. When I try to do something on discord the screen glitches out and my game gets minimized. Discord then gets transferred to my main display.

Dual Monitor Problem


Overall I'm delighted with Windows 10 but I have one relatively minor problem with my dual monitors. The taskbar on the second monitor won't auto-hide. It just sits there.

Any suggestions?

 

DUAL Monitor problems

Hair Tearing Time

I am having more issues getting dual displays to function properly on W10. It seems to be two fold.
Resolution and PnP detection. Same two monitors on Win 7 machine work just fine.

Here is the setup.

• 4 Desktops.
• 3 run Win7 one runs Win10
• Startech KVM 4 port dual mon KVM switch. ( #1=1 DVI, #2=VGA )
• Two identical HP l2045W monitors.

Win 10 machine yesterday I dragged window over to #2 and it was much bigger. Checked an resolution had changed itself for some reason. I reset so they matched and then the #2 just went black.

Checked by switching to Win7 machine and it was fine. Monitors and KVM doing as they should.

When the win 10 machine boots mon #2 has warning from monitor that there is a resolution miss match and a few seconds later shuts off. I check settings and in Win 10 the resolution is set as is should be which matched the suggested resolution on the warning from monitor.

I check the device manager on both machines.

In Win 7 I have two PnP monitors as it should be. Win 10 it says I have one PnP and one non-PnP ?

As stated it is only Window 10 that appears to be brain dead with respect to dual monitors. Win 7 works fine every time. Why won't Win 10 recognize only one mon as PnP and is this the bug that's causing my problem when I switch with KVM?

Also...when I can get second screen working the mouse won't travel over.

( There are no updated drivers etc. for monitors )

One more thing I would like to add is that the task bar on the second monitor does not show time and the system tray. How do I enable that?
