Is a 24-inch 1440p monitor sharp? PPI and fractional scaling guide
122 PPI is a niche sweet spot, sharper than 27-inch 1440p and physically smaller, so it suits tight desks and anyone who prefers visual density over real estate. You'll need OS scaling to make the native 1440p workspace feel like a typical 1440p monitor rather than shrunk-down 4K.
A 24-inch 1440p monitor delivers 122.41 PPI, genuinely high density for a desktop panel. This is the territory where text starts to look print-quality at normal desk distance and sub-pixel rendering artifacts become essentially invisible to the eye.

How this is calculated
Retina distance works out to 28 inches (71 cm), which is roughly where most people sit at a desk. The flip side of the high density is that native UI elements become small. Windows and macOS both assume ~96 PPI by default, so you'll want 125% display scaling on Windows (or just rely on macOS's Retina scaling on a Mac) to keep menus and buttons comfortable.
Verdict
A 24-inch 1440p panel packs 3.69 million pixels into a smaller chassis than its 27-inch sibling, hitting 122.41 PPI with a Retina distance of about 28 inches (71 cm), which is roughly the typical desk viewing distance. At that density text starts to look print-quality and sub-pixel rendering artifacts become essentially invisible, which is the draw at this size. The cost is that native 1440p UI elements at 122 PPI are small enough that 125% Windows scaling gets the workspace back to a comfortable size, which is the operating-system tax for the higher density. The 24-inch 1440p is the niche pick for tight desks and high-density preferences against the 27-inch 1440p alternative, which delivers the same 1440p workspace at 109 PPI without needing scaling.
