Problem running two monitors

[Lil Bear]

Hey guys I was hoping someone could shed some light on my issue I am currently having.  So I currently built a new computer and got a new monitor to replace my old one. My old monitor is a dell 60hz monitor, not quite sure on the model off the top of my head but hopefully someone can still resolve my issue.  With my new build I am running a 1080 ti Strix with a Asus PG279Q ROG Swift Gsync 165Hz Monitor, using Windows 10.  I have them both plugged into my graphics card, but for some reason when I do so my main monitor defaults to 60Hz and to make things more confusing when I am sitting at my home screen it is showing both monitors as mirror images.  Also when I try to open an application the application opens down on the task bar but I cant get it to actually pop up on the screen.  When I unplug my old monitor from the GPU ever thing works fine. I even tried going with one monitor and going into my settings to make sure everything was properly set for two monitors and everything was how I think it should be set to run two monitors. Please help

Right click on desktop > display settings

 

What do you see there?

You need to set up your monitors for extending rather than mirror.

 

If you're on Windows 10: https://www.groovypost.com/howto-windows-10-dual-monitor-setup/

 

If you're on Windows 7:

• Right click on an empty desktop area
• Select "Dispaly" in the menu
• On the "Multiple Displays" option, select "Extend these displays"

If you need to set up the refresh rate, you may need to adjust that in NVIDIA Control Panel.

I was able to fix it at lunch. It was a setting in NVIDIA where it was showing my main monitor as two monitors for some reason. (Have no idea why, but after I turned one off and plugged in the other monitor everything worked fine with a little bit of tweaking!) Thanks
