Do you have a 24.5" monitor or two monitors that equate to that screen size? The latter of which would still have the scrolling issue I think.
I have two monitors, One is 24.5" inches at the diagonal, the second is 21.3" inches at the diagonal.
When discussing the issues above (using the zoom feature of the browser) I am discussing how the image appears on the 24.5" monitor (on just one monitor).
I can in fact stretch in image across both monitors and have 45.8 diagonal inches of pond boss forum but that's just crazy talk.
Trust me you do not want to see the photo of DIED's tarantula stretched across two monitors.
