![]() ![]() Guitar Hero 3 loading screen alerting users of the featureīut what would happen if the user had different delay for sound input and video output? This could happen if the user separates audio and video before it enters the TV, as happens in the case of an audio reciever, or if the HDTV simply does not try to sync audio to the post-processed frame. Having trouble hitting notes? Try using the Calibrate Audio Lag tool in the Options menu. As both of these games were originally designed for the Playstation 2, where a minority of the user base would have had HDTVs, having only this option is understandable. In the first Guitar Hero game in 2005, as well as the second game from 2006, calibration was simply performed by having the player play back a pattern of sound cues synced with on-screen blobs passing a target. ![]() "Guitar Hero" Era Rhythm GamesĪs HDTVs became more popular, calibration options in games where such sync is needed became more full-fledged. ![]() While viewing TV or non-interactive video (the viewer does not have a frame of reference for when the picture "should" appear) or slower or non-rhythmic games (the viewer can forgive a slight delay between pushing a button and getting response, and games are usually designed around some degree of lag) are typically no issue for the user, rhythm games where a sound or cue on the screen must be paired with pushing a button on the controller within a given timing window can become unplayable if the timing window is unpredictably moved away from the note. This delay can typically be reduced by setting some HDTV models to "game mode", or manually turning off post-processing options one-by-one in the TV's settings. Processing the frame takes time, delaying input-to-output time. Extreme delay numbers in HDTVs are usually caused by post-processing to improve the image quality. HD monitors can have anything from hardly any delay between the screen getting the signal and outputting it - for example, a computer monitor - or anything up to extremes of 300 milliseconds or more of delay in certain HDTVs. Before HDTVs were the standard screen for home consoles, calibration options in games were more rare and usually less featured than today's HDTV consoles. ![]()
