The Sega Nomad’s screen has not aged well. Between it’s terrible quality compared to modern screens and it’s heavy battery consumption, users of the Nomad usually prefer to upgrade to a modern LCD screen.
Up until recently, most screen replacement options used composite video to drive it and while that was still an upgrade, feeding the LCD an RGB signal provides a much sharper image and much more vibrant colors! So far, only one company has produced a board that drives the LCD panel with an RGB signal; First releasing the ‘LCDDRV’ and now a follow-up product called the ‘RGBDRV’. This videos compares them both!
