ok what you need to do is go in to your roseonline file and find the sevenhearts file and open it in notepad you will then see your resolution like this.
[RESOLUTION]
WIDTH=
HEIGHT=
you will need to no your max screen resolution of your screen and half the width and hight of it to find out the resolution of your screen right click your desktop and you will see a tab and it will have your screen resolution. now this will not be perfect you will need to play around with it a bit to get it just right you may need just take off 10 or 20 on half of your resolution.
Do not forget before you do this move all your stuff to the top left of your roseonline screen like character info/inventory/skills/skill bars etc.
when you are done it will look something like this
PS.in gen patch you can set your resolution manually on setting
hope this helps
