TurboVision is a [[TV tuner]] adapter for the TurboExpress converting the TurboExpress into an [[handheld television]].<ref name=":0" /> The accessory was available at launch for {{US$|100|1990|round=-1}}.<ref>{{cite magazine|url=http://archives.tg-16.com/PLAYBOY/Playboy_1991_04.pdf|title=PlayBoy Collection|magazine=Playboy|publication-date=April 1991|via=tg-16.com|archive-url=https://web.archive.org/web/20170105223547/http://archives.tg-16.com/PLAYBOY/Playboy_1991_04.pdf|archive-date=January 5, 2017|url-status=live}}</ref> It allowed a player to either watch television, or go back to playing games with the flip of a switch; in other words, one may use the TurboExpress as a video monitor. It includes an [[RCA connector|RCA audio/video input]] for external [[composite video]] signals. Due to the widespread adoption of [[digital television]] and the [[HDTV]] standard, however, the adapter will no longer function as a television in most places due to the lack of any HDTV digital processing circuitry (the tuner can only process an [[analog signal]] for television). Due to this limitation, the TV tuner adapter is now relegated to a collectible for most people, although its RCA audio/video input function will still be operational (albeit limited with its low screen resolution).
