VAR technology will be used during the EFL Cup final between Arsenal and Manchester City, and supporters will be informed when decisions are being made via Wembley Stadium's big screen.
No match incidents will be screened during the game, but fans will have immediate confirmation that the referee is consulting the system as and when it happens.
"This cup final will be the biggest game for VAR in England so far," EFL chief executive Shaun Harvey told The Times.
"If there is a notice on the big screen explaining why there is a delay to the game then we hope that will improve communication to fans inside the stadium and on television.
"If everybody in the stadium knows what is going on then that's part of the overall education of what VAR can achieve."
Neil Swarbrick will be the video assistant referee for Sunday's EFL Cup final, charged with advising referee Craig Pawson.
