Screen resolution is the amount of pixels that display on your screen - the higher the number, the more pixels are displayed on your screen.
Higher resolution yields better quality picture but also makes the picture look smaller.
A lower resolution will make everything look larger on the screen but the quality will not be as good.
Here I will show you how to easily change the screen resolution in your Windows Vista computer.
go to an area of the desktop where there are no icons - right click with the right mouse button on this "blank area" 2.
a menu will now appear - go to the bottom and click on the item called "Personalize" 3.
once you are in the personalize menu, go to the bottom and click on "Display Settings" 4.
the display properties will now show up on the screen - find "Resolution" towards the bottom left of this display box 5.
under resolution you will see "Low" on the left and "High" on the right with a toggle button in between them 6.
if you toggle the button all the way to the right, the highest supported screen resolution will display, if you toggle the button to the left, the lowest screen resolution will display - you can choose a setting i between also 7.
click on "OK" when you find the desired resolution - Windows will always test the new resolution and ask you if you want to keep these settings.
Sometimes, the resolution will not work with your screen and all you will see is black - if this happens, do not press any keys on the keyboard, the original working setting will come back after a few settings.
This is very important because if you apply the settings that do not work, you will not be able to see anything on your screen which can create a problem! Congratulations, you just changed your screen resolution in Windows Vista.
