Site looks zoomed in clients IE7 but isn't

Hi guys, a client sent me this screenshot of his site, the image on the left is flash - but it’s supposed to go all the way across the width of the page and dock with the grey column on the right (where it says “need help”).

There isn’t supposed to be a white space in between. And his website is 1200 pixels wide rather than 950px.

I can only get it to look like this if I zoom in using my IE7, but according to his screenshot - he is at 100%.

Can anyone tell me how or why his website is looking like this?

I’ve tried increasing the font size in the “Appearance” settings, as well as changing the DPI settins from 96 (normal) to 120.
