Monitor picture doesnt fit the screen with HDMI but does with a D-SUB cable?

Like the title says i have a new monitor (Liyama E2409HDS) and when i use a HDMI cable the picture has about an inch border all the way around and with a D-SUB cable it is fine. I have fiddled with all the settings but nothing. Also i have noticed that when i plug it in with a D-SUB it does an out adjust but doesnt with the HDMI cable.
