1 If you are in one place for say 90% of the time, and then travel with the laptop occasionally (Scenario 2), then you can consider a docking station setup at the office (see image below). In this scenario, you would have:  1366 x 768 laptop Screen Resolution to work off the 10% of the time you are not at your desk.
Display resolution is not measured in dots per inch as it usually is with printers. However, the resolution and the physical monitor size together do let you determine the pixels per inch. Typically, PC monitors have somewhere between 50 and 100 pixels per inch. For example, a 15-inch VGA (see display modes) monitor has a resolution of 640 pixels along a 12-inch horizontal line or about 53 pixels per inch.
