I just found out that playing in a res lower than native highly affects graphics ,so when I tried to change it to native ,it didn't show up on win10 settings ,and when I try to I install driver of monitor(dell e1914h)it says monitor connected is "AGO plug and play"and drivers found"e1914h" ,driver which can be Installed"none" .I think my monitor drivers are not installed because when I tried to install dell monitor manager it showed that there isn't a compatible display found even though it is as shown in dell website.Any help?
