Print Image Specifications. Images used for print are usually much higher quality and resolution than those used for websites and are consequently much larger files. In general, your images should have a resolution of 150 to 200 dpi for newspaper print and 300 to 400 dpi for glossy print. For high quality commercial print your image resolution will probably need to be as high as 600 dpi.
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.
