Higher pixel density on 27"? 1080p is around 82 ppi compared to around 100 on 1440p at that size, makes the image sharp as fuck, negating the trend of blurry visuals everyone in the industry has been jerking it to for the last two decades. Same reason for downsampling larger resolutions, makes the image even sharper if you're into that, and in some cases makes anti-aliasing redundant so your games no longer need to look like somebody coated the camera in Vaseline.
