[Laptop] My second screen goes black for 2-3 second very often

[ilkerpolat3]

Hi everyone,
When I connect my Lenovo G5070 laptop to second external monitor with VGA, my second screen goes black for a while very often. When I switch my OS from Win10 to Linux ( both of them installed and grub also), my second screen work very well I searched for help on the internet and I tried to many of them but they did not help. These are what I tried for so long:
+Change cable
+Change monitor
+Change resolution
+Change main screen as an external monitor
+Update GPU driver
+Update every driver
+Shut down computer...... Pray a lot........ Try again........
I believe that the reason for this is something on software. Otherwise, It shouldn't work for Linux also. Do you have any idea?
Thanks

The G5070 does not have a VGA port according to Lenovos website, so which HDMI to VGA adapter are you using? I suspect that is the source of your problem.
