Fullscreen crash when resolution doesn't match monitor's

Hi all, I apologize if this has already been addressed in a previous post, but the last posts I saw about it are back from 2010... is this still an issue? I cannot get fullscreen to work unless the game resolution is set to exactly match my screen resolution. This poses a problem because I play on a TV that's set to 1920x1080 and the game text is TINY at that size. I would like to both play in fullscreen and set the resolution to something lower, say 1280x720, like I can in FFXI without lowering my TV resolution as well. Is this possible, or is it just something we have to live with?

Final Fantasy XIV config >> General >> Video Settings (tab) >> Window Size

Also if you go to the configuration settings while inside the game and go to i think its log settings you can change the text size from medium (which i think is the default) to large.

Sorry, I think maybe my post wasn't very clear... I know how to change the resolution of the game, but if it doesn't match my computer resolution, it will boot up with a black screen and just sit there. I have changed the log text size to large, but all of the menu text remains tiny and pretty much unreadable.
