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?

Hi Max,

Thank you for posting your query in Microsoft Community.

I understand that you are having a tough time working on the computer.

I will certainly help you to resolve the issue.

• 
  What happens when you try to connect the second monitor?
  
• 
  Do you receive any error code/message?
  
• 
  Have you tried to connect the second monitor on a different port?
  

I suggest you to connect second display using a different port available on your PC and check if the second display works. If second display works in other port, then the possible cause for this issue may be discrete video card driver.
