I already looked at the monitor. You can easily check this by setting your current monitor to 1440X900. Seems to me to be plenty of room for any app I'v ever used. Now just add twice as much to either side and have room to work many apps at once.

BTW: the 900 number has NOTHING to do with the LPI of any monitor as previously stated. It's merly an aspect ratio setting for fitting the image to the dimensions of the panel.
