What is screen resolution you say? It refers to the amount of pixels (little colored dots) you have on your screen. The most popular resolution nowadays is 1024×768. That suits a 17 inch monitor perfectly. However some people have a lower screen resolution like 800×600 which makes your icons and web pages look overly large. To change your screen resolution in Windows follow the steps below.
1. Simply go to your desktop and right-click on some free space. A grey menu box will appear. Shown below.
2. Left-click on Properties near the bottom of the menu. A large Display Properties box will pop up. Shown below.
. Select the Settings tab in the Display Properties box.
4. Use the little slide bar near the lower left of the Display Properties box to adjust desired screen resolution and then click Okay.
Then Windows will confirm that you do want to change your screen resolution. If you press ok it will change immediately. You will have to confirm again and then your done.
