Can you prevent lower resolution from filling entire screen/going full screen?

Is it possible to make it so your display (LCD monitors and notebook LCDs) does not fill the entire screen (or going full screen) when you set a resolution below it's native ? ie something similar to what background setting options you have for Windows 2000 and above, where instead of stretching a background image too small to fill the entire screen, i only want the background image to be shown in its original size

turn of scaling in the osd

Where would that option be?? Does that have anything to do with DPI settings?

the buttons on the front of your monitor
