I have recently switched from a Apple thunderbolt display to an 27&quot; 4k display from Samsung. I can&#x27;t speak for other platforms but OSX lets you use the 4k in &quot;retina&quot; mode thus doubling the pixel density. So you end up with incredibly sharp text. Since it is possible to adjust the scale via software you can adjust for more space &#x2F; better readability depending on the needs at hand. For me the switch was as big of a switch as going from low-res to hi dpi phones. I really love that you can have good legibility with much smaller text in editors &#x2F; terminal. After all I can say that while I am missing the docking &#x2F; hub &#x2F; power plug &#x2F; webcam features of the thunderbolt display (colors where also better) due to the increased sharpness and the (perceived) productivity gains I would never switch back to less than 4k for a workstation screen. So purely subjectively speaking: 4k is just the business.
