The website designer will usually customize the site for the best viewability based on the standard viewing area of its users. That used to be 15", but has now progressed to 17" on most sites. Some will set their site up so that it will adjust to the size of the user's display, based on percentage, but if not you're pretty much stuck with viewing the site as the author had intended. There may be a plugin available for IE that will blow up (zoom in on) the entire page to automatically fit it to the width of the browser window, but that's something I haven't encountered.
I have a Compaq Presario V2200-wide screen. It runs Windows XP and I use Internet Explorer. I want to find out how I can make use of the wide screen but so many web pages/sites on fill about half of the screen. Setting the text view to the largest size doesnt help and Im hoping someone can tell me what to do. Thanks
