Hi! Everyone, hope you all are fine.
Today in this post I will tell you how you can enlarge any portion of your computer. If you are teaching a group of students with a single computer in a room and a projector so that students can also see able to see computer screen. So now while you are typing something in a form in computer but students at the back couldn’t able to read it so how will they understand what you are typing, will you tell everything verbally? No, there is a batter option then that.

Windows Magnifier can help you to magnify anything on your computer screen. To run Windows Magnifier click on Star button 
–>All Programs –> Accessories –> Ease of Access (or Accessibility) –> Magnifier.
Here how you can control Magnifier. To zoom in or to zoom out, click on Plus or Minus sign. To control the position of magnified portion (only for Windows Vista and above) click on Views and select anyone of the follow option
- Full screen mode – In full-screen mode, your entire screen is magnified. You can then have Magnifier follow the mouse pointer.
- Lens mode – In lens mode, the area around the mouse pointer is magnified. When you move the mouse pointer, the area of the screen that’s magnified moves along with it.
- Docked mode – In docked mode, only a portion of the screen is magnified, leaving the rest of your desktop in a normal state. You can then control which area of the screen is magnified.
Note: – Full screen and Lens mode only works with Aero, so if you are using Windows XP (or older version) or your computer doesn’t support Aero or you are not using Aero theme then it will work in Docked mode only.
To customize more settings, click on Options icon and select the settings according to your wish.
