Weather historian Christopher Burt described this as the greatest cold wave in modern U.S. history in his book, Extreme Weather. What made this outbreak worthy of its lofty status was the magnitude, areal coverage and longevity of the cold.
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.
In the highest resolution you posted above (2560x1440), you are only getting that resolution and your screen is stretching the image (causing a loss in quality). The fact that your Mac says that the 1920x1080 resolution is not scaled leads me to believe you are connecting via HDMI.
