title: Batch file to change screen resolution in windows 7
body: <p>A colleague has a two line batch script to open excel when he logs in to his pc. He just doubleclicks it and has recently copied it to his startup folder so its automatic. i was wondering if i could have one to change the screen resolution when doubleclicked.</p>
  
  <p>The reason for this is i regularly connect to an overhead projector, but my resoulution on it is wrong and i have to manually change the resoulution and then change it back when im done.
  I am avoiding having to install anything, so if possible, any solution should be a self-contained file (it's a work laptop!) </p>
  
  <p>i was thinking it may be two files needed, the first to change resolution to 1024 x 768 and anotherto return it to 1280 x 1024. All help is appreciated.</p>
  
  <p>cheers</p>
