2048x1080 (code name "full container") is not very common for Digital Cinema.

What is used in the field is
2048x858 : 2.39 aspect ratio ==> preset for projector is "Scope"
1998x1080 : 1.85 aspect ratio ==> preset for projector is "Flat"

For 4K, it the same with 2x the numbers.

Perhaps then resolution could be 
{"2Kfc",       2048x1080},
{"2Kflat",       1998x1080},
{"2Kscope",       2048x858},
{"4Kfc",       4096x2160},
{"4Kflat",       3996x2160},
{"4Kscope",       4096x1716}
