Why is my computer monitor wavy?

Why won't my monitor hook up to my computer anymore?

• I take my computer to a repair shop. After the repairs I take it back home, and everything is going fine untill I try to hook my monitor back up and guess what the monitor outlet want fit at all even though it's been sliding in just fine for the past three years. Also the monitor outlet is now green when it was blue before I took it to the repair shop. I called the techincian and he said he doesn't know what the hell happened. I mean I'm not accusing anyone of any wrong doing, but seriously how does a monitor magically not fit the computer anymore? Specs: I have a old Dell CRT monitor. The cord is big and blue with 14 prongs. The outlet on the back of my computer where the monitor hookup is supposed to go is now green(was blue at first) with 9 prongs. At first I thought the technician changed it, but I went fishing around for my manuel and the diagram in the booklet matches my computer specs exactly so it really seems like he didn't touch anything, and yet my monitor want fit anymore. It's a conundrum lol I guess this will give me an excuse to finally get a LCD monitor.http://www.walmart.com/catalog/product.do?product_id=10575203 However I don't want whatever happened to happen again so are there computer monitors with usb ports?

• Answer:

  Sounds like your trying to plug the monitor in a serial port, they are green with 9 pins. Check there isn't another socket, possibly with a plastic cover over it., it should be blue with 15 holes. Or maybe they took out the graphics card and forgot to replace it. You do get monitors with USB ports, but they just extend the USB ports on the PC to a handier location, basically the monitor has a USB hub in it. You still need the seperate video cable to get picture.
