The mathematical aspect ratio is 8:5 but people use 16:10. For
instance:

    > git grep 16:10
    parse-base-block.cpp:749:                      x[14] & 0x20 ? " 16:10" : "",
    parse-base-block.cpp:764:                       printf("16:10");
    parse-displayid-block.cpp:284:          s += "16:10";
    parse-displayid-block.cpp:471:          s += "16:10";
