The pillar boxing on my screen is so huge that it makes the play screen tiny. It won't let me change the resolution in any way I can tell. Is there a way to change the resolution that I am missing?

Thanks for any help!

Download MMResTool027fix2.zip and extract it into the installation folder - http://www.celestialheavens.com/forums/viewtopic.php?p=273410#273410
Edit mmt_d3d_screen.bat and set the resolution you want, then save the changes and run it.

You can try changing the scaling setting in your Display settings first

How would I go about doing that ZFR?

Solved: I went to Nvidia control panel and under "adjust desktop size and position" and clicked full screen!

Thanks for the tip ZFR!!
