The Effect of CRTs on Pixel Art (2024)

This article explores the historical and technical relationship between Cathode Ray Tube (CRT) monitors and the development of pixel art in early video games. The author argues that pixel art was never intended to be viewed as sharp, square blocks on modern LCD screens. Instead, the inherent characteristics of CRT technology—such as scanlines, phosphor glow, and color bleeding—acted as a form of hardware-level anti-aliasing. These features blended individual pixels, creating smoother transitions and more complex color palettes than the raw digital data suggested. The piece highlights how modern emulators often fail to replicate this aesthetic, leading to a distorted perception of classic game visuals. By analyzing how artists utilized the limitations and quirks of CRT displays, the author provides a compelling look at how hardware constraints fundamentally shaped the artistic direction of early gaming, suggesting that the 'true' look of these games is inseparable from the display technology of the era.
