Dual GPU issues

Go to solution Solved by jaslion,

Just get an adapter. The gt 620 is removed from support and driver updates before the 2070s even launched so compatibility between them is basically not happening.

I have been trying to put my old GT 620 into my system with a 2070s because I need an extra HDMI port and would rather not buy an adapter. The issue is when I put it in it disables my extra displays and my 2070s goes down to 1080p at 64hz  rather than 1440 at 155hz like the drivers were uninstalled. Then I would get the drivers for both and the same thing happens.

notes whenever the gt620 is in the 2070s uses windows display drivers and device manager says it has a problem.
