I have just reformatted my pc using the original windows xp discs, everything is ok but the second monitor is not being recognized. The second monitor works ok but it is just a clone of the first one with a start button lower left etc, the mouse moves both at the same time. I have looked in 'display properties'/monitor' but there is nothing at all to enable me to join the monitors as one? Any help appreciated
Go to properties (right click on the desktop) --> settings --> check the following box "Extend my Windows desktop onto this computer" That should do the trick
