Okay so after playing around with it I didn't apply enough brute force

Its looking like it should now
What is the best resolution I should have with the following monitor
iiyama Prolite XB2283HS
Ive currently got it set up with a VGA in the monitor going into a VGA > DVI adapter.
I was thinking about getting a HDMI > DVI adapter, is that recommended or should I stick to VGA?
Also I can see some "ghosting" on the screen, what is the best way to get rid of that?
Thanks
