Windows 10: LG Monitor and mac laptop not syncing

I have an LG monitor as my large screen attached to a mac laptop. When I open an excel spreadsheet, the file shows up on the laptop screen but not on the LG screen. How can I fix this?

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?

Laptop External Monitor Problem

Discovered the best interim solution and best way to live this problem:

• I have changed my LG TV auto power setting to OFF - therefore the monitor remains ON constantly and therefore laptop instantly presents a display to my monitor, sleep, restart etc..

The critical issues being in this bizarre problem :-

• Windows 10 HP laptop is both physically and S/W connected to LG monitor
• LG monitor can take up to 45mins to present this display on each and every day
• Connected laptop via HDMI to three other monitors(TV’s etc), same problem, one TV was less than six months old
• There appears to be raised problems generally in relation to such an external monitor problem on the WWW
• Never incurred such a problem in Windows 7

I stress these are the facts of my problem and thank you again
