How to Change Screen Resolution in Windows 7
You can adjust the screen resolution in Windows 7 to control how sharp and detailed the images, words, and icons on your screen appear. At higher resolutions, things are crystal clear, but they're also much smaller; at lower resolutions, things are larger and easier to see, but there are fewer items visible at any one time.
This is really a personal decision; there is no right or wrong setting. However, if you plan to spend much time in front of a computer: adjusting the screen resolution to what feels comfortable to you pays off in increased productivity as well as decreased eyestrain.
Choose Start→Control Panel→Appearance and Personalization and click the Adjust Screen Resolution link.
Adjusting the screen resolution will adjust the resolution for every user account.
In the resulting Screen Resolution window, click the arrow to the right of the Resolution field.The Screen Resolution dialog box.
Use the slider to select a higher or lower resolution.
Sliding the resolution down will make the items on your screen larger, but also a bit fuzzier.
You can also change the orientation of your display by making a choice in the Orientation drop-down list. The Advanced Settings link in the Screen Resolution dialog box displays another dialog box where you can work with color management and monitor settings.
Windows will show you your desktop at the new resolution and ask if you prefer the new setting.
Click OK to accept the new screen resolution or Cancel to go back to the old setting.
If you don’t click OK within a couple of minutes, the previous setting will be restored automatically.
Remember that you can also use your View settings in most software programs to get a larger or smaller view of your documents without having to change your screen’s resolution for the entire system.
