I use an X1 Carbon with a 14" 1440p screen. It provides sharper text, better rendering of high-res photos, more working area, and the ability to run a 1080p VM

I use an X1 Carbon with a 14" 1440p screen. It provides sharper text, better rendering of high-res photos, more working area, and the ability to run a 1080p VM or play a 1080p video in a window or browser tab. I absolutely consider this screen worth the premium.
