Main External Monitor Not Working After Windows Update?
Hi. I know this is windows 10 forum but i like advice.
I had a windows eleven update and then restarted my laptop. I use 2 external monitors with it. One is a 32' 4k monitor and the other is a 24' monitor.
I noticed after I restarted it, it showed the percentage update on my 2nd external monitor. Usually whenever it does the windows update, it would show it on my laptop screen or my main external monitor. After the update, it displays my 2nd external monitor as my main monitor. My main 32' 4k samsung monitor doesn't seem to work? When I go to display option, it does show 3 monitors though.
I went to restart my laptop and after doing this, only my 2nd external monitor and my laptop screen shows a screen. My main 32' 4k monitor doesn't seem to do anything? When I click on the power button on it, all it does is show displayport on the top left corner. I can power it off as well. But why does it not display my 32' 4k monitor?
This seems to be it

So it shows my laptop screen as monitor 1 in display. Shows smaller monitor as monitor 3 in display next to it. My big monitor is monitor 2 but you can't click or drag it? So it does detect it as even device manager shows it.
But why does it not show anything? This happened right after i restart laptop for update so this isn't a cable issue etc.
What are my options now? Go to display?
The update was done very quickly, no bios update.
Also when i check the display, it shows it as display 2 and not active. So that has to be the reason right? The laptop screen and other monitor works fine and shows the display properties and resolution.
Should i uninstall the windows update? Notice when i go to updates, it shows the update i did earlier
security update for microsoft windows kb 5023706
Also it shows my previous two other security updates i did before this.
Would powering off my laptop and then unplug the power cable from the bigger monitor and laptop and plug it back in and then power on laptop be good idea? Tried that and same issue.
My bigger monitor is connected by usb c to displayport.
My smaller monitor is connected hdmi to dvi cable. The dell 20A adapter is connected to my laptop and hdmi to dvi cable is connected from there.
So this windows update caused this? Anyone can please give me advice here?
