You need to adjust the 540p mode so its refresh is fast enough to
display the fields sequentially.  You're looking for 59.94 Hz in the US
(not any less, not even 59.93).

You need to set the DisplaySize attribute in your xorg.conf since your
pixels are not square.

You can find more about both these issues by searching in the list
