I had a friend who gave me a Mitsubishi monitor. The monitor wasn't getting a picture for some reason, so it obviously needed some servicing. I took it to a repairman to see what could be done.
Technician : "You mean you get no picture at all when you boot up your computer?"
Me: "That's right."
Technician "Oh, that's because you have a small hard drive. You have to get a bigger hard drive and then the monitor will work fine."
