While many may opt for a 1440p monitor since it's cheaper than a 4K monitor; text and images simply look better and sharper on a 4K resolution monitor. You can't make out the individual pixels, not unless you put your eyes just a few centimeters away from the monitor. Not to mention, those who are content creators by day and gamers at night would also benefit from a 4K monitor thanks to the real estate that it provides. I prefer to edit my photos and videos on a 4K monitor.
