Yes this is a problem with this template which i have yet to find a solution for except to create a banner that is long enough to fit most browser sizes.

When this style was released 1900x1200 resolutions were unheard off, so i made the header image 1400 pixels wide.

If you have a wider screen than 1400 u can widen the image to 1900 but remember that the file size can be very big.

I have had one idea where i would fix the background image and then have a second simple background image but this would not look so good i reckon.

As for the name of the your forums added to the header banner, i suggest adding the text to the left hand side and mininum of 800pixels across
