That doesn't make any sense. A 24" 1080p monitor has the same "effective DPI" (actual physical size of things on screen) as both a 32" 1440p monitor at 100% scaling AND a 32" 4k screen at 150% scaling. You would be getting literally the exact same amount of screen space on the 4k display at 150% as you do on your 1440p screen, except that it would be even easier to read because the text, for example, would be sharper.
