After taking a screen shot from your computer, have you found the resolution and overall quality to be lackluster? Resolution makes a significant difference in the image quality of a screen shot. Resolution refers to the number of pixels (or dots) per inch of the image. A higher resolution means improved quality. There are steps you take to increase the resolution of your next screen shot. And it won't cost you a thing.

Select the "Settings" tab.
Increase your screen's resolution by adjusting the marker under the "Screen Resolution" heading. Increase the resolution as much as you want and then select "Apply" to test the results. If you are still able to see your toolbar and icons, then leave your resolution at the new settings. If some of your desktop items are no longer visible, bring the resolution down until you find the correct fit.
Click "OK" to save your settings when you have settled on the proper resolution.
Run GIMP. If GIMP is not installed on your computer, download it for free (See Resources). GIMP is a freeware image-editing application.
Select "File" and "Open." Highlight the screen shot that you want to enhance. Select "Open."
Choose the "Image" menu. Check the box next to "Scale Image."
Find the resolution fields in the same window. Alter both "x resolution" and "y resolution" as much as you would like. Select "Scale."
Choose "File" and "Save" if you like the end result of the resolution changes. If not, you can adjust the resolution more until you are satisfied. Save when finished.
