I have found exactly the same problem - it is just a narrow band down the centre. I have search the net high and low but cannot find out how to make it show like XP. yes, I can zoom, BUT, I have my own site and can see that it distorts some of the words etc. on there by doing 150%, and 200% is off the screen! It was normal in XP, easy to read and filled most of the monitor. Please can you let us know how to alter this, I cannot belive I have upgraded and now struggle to read my webpages - when i use preview to check my work, i have to have it on the normal or it can sometimes not look the actual format. I would be soooooo grateful for a solution.
