You should be able to use similar relevance that you created in your analysis to detect if changes need to be made on the target computer.
I have used the program QRes to do this through the command line outside of BigFix / IEM, but it should work there too.
I feel like there might be a more efficient option for detecting screen resolution settings in windows without using WMI, but I would need to look it up.
