|You set the position of the image and the vertical and horizontal size of the image on the external monitor itself - e.g. by pressing some button to pop up configuration settings, and adjusting settings. Once you have set that for a particular computer's particular video adapter, you usually don't need to fiddle with that again. |
If Windows has the monitor set to Default Monitor in Control Panel - Display Properties - Settings, you will have fewer resolution and numbers of colors choices in Windows.
In that case, go to Control Panel - Display Properties - Settings - Advanced - Monitor and change the Driver to Plug and Play Monitor, or use Have Disk and load the specific drivers for the monitor model (recommended and important for LCD monitors) - they're usually on the CD that came with the monitor, or are usually available to download from the monitor manufacturer's web site - Windows is looking for an *.inf file - you may need to change the folder it looks in to find that.
You set the resolution and number of colors in Control Panel -Display Properties - Settings in Win 95 thru XP.
The resolution determines the default size of the icons on the screen and how many will fit on the desktop screen.
There are standard 4:3 ratio resolutions (e.g. 800x600, 1024x768, 1280 x1024) and sometimes wide screen ratio (e.g. 16:9 ratio; 1280x768) resolutions to choose from in Windows.
The monitor display is either the standard 4:3 ratio display (if it is more than about 4 yearsold) or a widescreen ratio display (if it is newer than about 4 years old).
If you choose a standard resolution for a widescreen display, either the display will look stretched horizontally, or there will be black areas right and left.
If you choose a widescreen resolution for a standard display, either the display will look stretched vertically, or there will be black areas top and bottom.
If the monitor is LCD, all LCD displays have a specified "native" or "optimal" resolution they look best set in when set to - other resolutions will not look as good, the most noticable thing being the text on the screen will not look as clear.
Turn on Clear Type in Windows XP or Vista - makes type/fonts on LCD screens look clearer.
