I have a milky white iMac and the LCD went bad. It's not worth spending a grand to replace the LCD but the rest of the computer is fine so I thought I would put it to good use. So, I ported out the video to an external monitor. Only one problem...... All I'm seeing is the wallpaper. No icons. No Menu Bar. Nothing except the wallpaper. I'm pretty sure it's a resolution issue but I can't get to anything to change it. I can right-click on the desktop but the options are limited and certainly don't let me change the resolution. Any suggestions?
