I did a quick search and didn't find anything so excuse me if this has been asked before. I have a late 2013 27" iMac (resolution: 2560 x 1440) My second monitor is a 27" LG (resolution: 1920 x 1080) While in mirror mode, the LG monitor scales everything to look like the iMac desktop. Of course it's not pure 2560 x 1440 but at least all items on the screen match the iMac screen from a size standpoint. When I switch to second display mode, everything on the LG montor looks bigger (mainly because it's not doing any scaling effectively blowing everthing up due to the screen resolution difference). Is there any way to fix this? Thanks.
