I just want to say that this thread helped me. My 60" Sony LED display was set to display auto screen size, which goes by the "recommended settings" which are of course ambiguous. I looked at the user guide, and there was an option to change it from "Auto" to +1 or -1. +1 is actually the setting that displays the image exactly as it should be, while -1 pushes more off the edge of your screen. I set it to +1, and it was a huge difference in FFXIV. All my icons were pushed inward, and when I moved them back to the edge, the edge of the screen was as far as they would go- before, they would move right off the edge if I kept going. There is a definite border now, which is what I wanted, so I expect all of the normal things that sometimes show off screen will not be able to do so now.

Also, I wondered why I didn't notice this before on other games/TV... not sure the answer, but oh well. It's set correctly now.

OP, try using your TV's menu accessed at the TV to adjust this if you can. It will help.
