Windows 10: Outer monitor and pc screen turns off when connected

Hello!So I have an old samsung monitor that supports only 1440x900 and 60 hz. And one time I stupidly set display settings so that screen 1 turn of when screen 2 old monitor, not pre-built in pc screen is connected. But I hadn't set correct display settings for it so it didn't even show anything on screen 2. And now when I connect pc to monitor my computers screen turn off and monitor 2, don't show anything because output is wrong. So I am blindly trying to set settings without seeing even where is cursor, because settings for monitor appear only when it's connected to pc.Any hotkeys to forc

Things to do once connected new G-Sync monitor

I'm getting my G-Sync monitor today.

I think I have to take the following steps:

• Connect 1440p G-sync monitor with DP cable
• Connect second 1080p 60Hz monitor by HDMI
• Startup PC
• Reinstall display driver
• Restart PC (I always do that after display driver install)
• Activate G-Sync in NV control panel (I believe also V-Sync is auto on after that?)
• Set my 1440p monitor from 1080p to 1440p
• Calibrate my 1440p monitor

Also ingame, I should turn off V-Sync?
Are there any problems running a second 60Hz 1080p monitor?

Is there anything else I should do/know?

 

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??

Thanks Elise,

I found more links which suggest

1. turn one of the monitor
   
2. feedback to Microsoft
   

Using Steps Recorder on Two monitors. (microsoft.com)

How to limit Problem Steps Recorder to single - Microsoft Community

I need assistance on both suggestions; how to

1. turn off laptop monitor?
   
2. locate feedback hub on Cortana?
   

My workaround is to use PowerPoint Screen Recorder but this need additional screen capture.

The reason for Screen Recorder is Windows 10 Mouse Cursor for Office Menu item disappear when select Screen Capture App. It is cumbersome to show Tech Support what is selected on Office App on captured screen...

Thanks Ahead!
