The easiest way is to choose which display modes you are interested in as game designer, check if they are available on client side, and display those which are correct. I dont think you need to display all.
Even so, let's say I want to include 1920x1080 in the list. When I enumerate the display modes, I get five different modes with that resolution. One is 50Hz, and four are 60Hz (either 59940 / 1000 or 59950 / 1000). At the latter ratio, there is one mode for each of three scaling types (unspecified, centered, and stretched). Out of the four 60Hz modes, which one do I choose? Even if we ignore the scaling type, there's still two 60Hz modes, and when we create the swap chain we have to choose one set of ratios... I'm just not 100% clear on the implications of choosing one ratio over another.
