If you are talking about pluging your 1.1:1 automotive tranformer into a 1:1 isolation transformer, then to your monitor, yes that will work. An isolation transformer is basically the same as a regular power converter type transformer. The difference is, most isolation tranformers are 1:1, and they usually have some sort of shielding between their coils. Technically though, all transformers isolate the power. connect the output terminals of one tranformer to the inputs of the other and you will serve your goals.
