It might be possible that the laptop did not come loaded with correct video/display software or drivers. By installing appropriate software or drivers, you should be able to get the 1440x900 pixels resolution.

The measurements used to determine a monitors screen resolution is Pixels per Inch (PPI). The size of a monitor in inches and the total pixels in the horizontal and vertical directions determines the PPI of the screens resolution. For Example a 15 inch monitor has a maximum of 1024x768 pixel resolution.
divide size in pixels with size in inches for width or height of photo and you will get resolution
It probably refers to the resolution of a screen. That would be low resolution.
It depends on the resolution of the device. For a standard 96 pixels per inch resolution, 250 pixels would be approximately 2.6 inches.
The ideal resolution for printing an image that is 1200 pixels square at 300 dpi is 4 inches by 4 inches.
I think what you mean is to change the resolution of the PDF files? 'Cause I found this : "e.g. a 300 dpi printer has "pixels" that are 1/300 inches in size, while a 72dpi monitor has 1/72 inch sized pixels. A 100x100@72dpi image on a monitor would have to be printed out at about 417x417 printer pixels to have the same apparent size (300/72 = 4.16666)" So if it does, here is the solution: In Adobe Acrobat, "Edit > Preferences > Convert to PDF", choose the file you want to change, select "Adobe PDF Settings > Editing > Standard" and then Edit again to change the resolution. May this will do some help.

Change = -6 inches so %age change = -6/12*100 = -50%
