Hoping someone can help me out with a problem I am having with my 2017 iMac running Windows 10. The problem is the operating system seems to only want to give me three options for setting the resolution, one in 5k, and the lowest one at 3200x1800 - I forget what the middle option is. This is a problem because the two games I am trying to play (Doom 4 & Steel Division) are only showing resolution options that match what Windows 10 offers, and this really takes its toll on performance. Does anyone know how to resolve this issue? Ideally I would like to set this at half the iMacs native resolution, but so far I have been unable to figure it out. Any help or guidance would be greatly appreciated.
