ok so its been awhile but reinstalling Battle.net to play some StarCraft2. everything went fine with the redownloading of Battle.net and installing Starcraft2. upon starting up the game i can actively hear the game running in the background at the main menu BUT i cant see anything. just a black screen with audio. help.
you need to reset your resolution to match the game resolution. easy way: on the battlenet app, click the setting next to play, click game setting, and in that menu there is an option to reset ingame setting. click that. That should fix it, if not youll have to adjust the resolution you are on and try to see what matchs the game .
