- Screen Resolution, Pixels, DPI, Spaces, and More -

In ONE WORD, Screen Resolution is the size of stuff on the Monitor Screen Resolution, Pixels, d.p.i. (dots per square inch) all fall into about the same category and can be very confusing because they mean different things to different people. So, for our purposes, we will tell you that Screen Resolution means how many pixels you have horizontally and vertically across the screen. AND we will tell you that a pixel is a unit of measurement or simply put, it is one space. Therefore, if you have a screen resolution setting of  800 X 600 pixels, it means you have 800 spaces across the screen and 600 spaces up and down the screen.

The following will show the user how to check and change the Screen Resolution when using Windows XP.   The number of resolution settings varies depending on the equipment being used, my system provides for 4 different pixel settings.
At the above main screen which represents the first screen after the computer boots up, position the mouse cursor in a vacant spot away from any icon and press the right mouse button.  A small window will open as shown in the frame below.
In the small window as shown above, select the word "Properties" and click the left mouse button.   After clicking the mouse button the window shown in the frame below will open.
The selections shown across the top of  this window are for setting the computer & software to your personal taste.   To set the screen resolution, left click the mouse on "Settings" up in the top right corner and the window shown in the frame below will open.
This window is for setting the colors and screen resolution.   Note the slider bar on the bottom left which in this case is indicating a Screen Resolution Setting of  800 X 600 Pixels AND look at the small window inside the sample monitor and take note of it's size.  By positioning the mouse cursor over the slider bar and holding down the left mouse button you can slide the bar over to the next setting and the setting will change as reflected in the next frame below.
This frame reflects a setting of 1024 X 768 Pixels and take special note that the small window inside the sample monitor is now smaller then in the previous frame.  The higher the resolution, the smaller the items are on the screen.
This frame reflects a setting of  1280 X 1024 Pixels and again take special note that the small window inside the sample monitor is again smaller then in the previous frame.
This frame reflects a setting of  1600 X 1200 Pixels and again take note that the small window inside the sample monitor is yet again smaller then in the previous frame.  Using my computer equipment, this is the highest resolution setting in Windows XP.

To change the setting move the slider bar to your choice and left click the mouse on the word "Apply" in the lower right corner.  After clicking on "Apply" the main monitor screen will change to the selected size and a window shown in the frame below will open.
As indicated above, this window allows you to select "YES or "NO" for the new setting.  If you do nothing the screen will revert back to the original setting in about 15 seconds as can be noted in the above window where it indicates 8 seconds left.
"The End of Windows XP Tutorial"
The number of choices in the settings of resolution depends on the version of Windows, the Video Card installed in the computer and the Drivers being used. My computer, video card and drivers happens to provide for 4 different resolution settings using Windows XP and when using Windows 98 it provides for 14 different settings with the smallest being 640 X 480 pixels.

Resolution in Windows 98 is set the same way except different looking windows will appear.  The resolution used depends strictly on an individuals requirements and intended use.  To assist in a better understanding of screen resolution and pixels, the bars below are set at the different pixel lengths.  The bars below run from 640 pixels wide to 1600 pixels wide.

If you have ever wondered why an image hangs off the screen and you need to scroll over to see all the picture you will now understand that if the Web Site is using images set at a high pixel width and your computer is set at a low pixel width then this is what happens.  Whichever of the bars below is exactly as wide as your monitor screen then that is the resolution your computer is set at. You can make any bar be exactly as wide as your computer screen by adjusting the Screen Resolution, i.e. the pixel setting.

Currently most Users operate with a setting of  800 X 600.  Remember, the higher the setting the smaller the objects are on your computer screen.

What is written here is an effort only to explain how to set your computers screen resolution.

You can learn lots more about resolution, pixels, dpi, etc., by searching the internet.  You can also become total confused because in my search for an understanding,  I discovered a pixel is not really a pixel and everybody has their own definition of what a pixel truly is.  I therefore decided the simplest explanation is, to tell you a pixel is one space on the monitor screen.

When scanning an item for use on the computer or a web site,  I suggest a resolution setting which will produce an image no wider then 700 to 800 pixels.  The setting to achieve 700/800 in width will depend also on the size of the item being scanned.  A post card will require a higher resolution setting then will a 8 X 10 photograph to produce the same size image in the computer.

If your scanning an item to have a printed photograph made at a photograph studio then scan at the highest resolution your computer can handle.
