I’ve just purchased a new Samsung monitor(LC34J791WTNXZA) for my pc. It’s now having trouble loading the game. Monitor is struggling as soon as I launched the game. Is there any settings that I should be aware of?
That is a 21:9 aspect ratio monitor. My guess is your old resolution saved in d3prefs.txt is incompatible with it. Try editing the values there then re-launch the game.
It maybe easier and faster to reset the game’s settings. Goto the Diablo III tab within the Blizzard application -> Select: Options -> Game Settings -> Reset Game Settings. -> Retest!
