[...] Ok, I plug the monitor into the hard drive and it works fine[...]
Wow you should teach me to do that!
But seriously, a hard drive is a component of a computer. So unless you're doing poetry and trying to use
synecdoche, please call a computer a computer or PC works too.
Anyway, their might be two reasons for your "blurriness":
1. The computer you connected the monitor with is set to the wrong resolution setting.
2. The computer needs updating.
Solution 1.Monitors, especially LCD, have native resolution. Resolution is basicly the size of the image that the PC creates when it sends images to the monitor. The monitor takes the image and compresses it or enlarges it to fit the screen. If you squish or pull an image it could get distorted. In order to avoid this, monitors have "native resolution" which just means "the resolution at which the screens works best with". If you can tell us if you have a LCD (Flat panel monitors) or a CRT (big heavy boxy old TV style monitors) and tell us it's size or model, we can recommend you a resolution that you can try setting your computer for better picture quality.
Solution 2. Computer have many components to work. One of which is called a "graphics card" or "Video card". This part translate digital information into images and sends that to the monitor. But to work properly, they need software that can run them efficiently. Drivers are software that run the hardware* and the more up-to-date they are, the more smoother they will run.
*Software: Programs/ coding in the computer
*Hardware: The physical devices that compose a computer
However, you need to know what kind of video card you have. To find out, one thing you can do is click on start then on run. A box will appear in which you can type. Type "dxdiag" and press enter. A new box appears, in the tabs on the top click on "Display1". You have now information about the video card. In the "Device" section, please tell us the "Name" and we can tell you were to go from here.
If you have any other question, don't hesitate to ask!
