Not necessarily — in many cases, an ultrawide 49-inch monitor can help add to the immersive experience. It really depends on the game for how wide the viewing window can be. Since many of the largest gaming monitors tend to be around 34 inches this is also around the size that most game viewing windows are. However, using a 49-inch monitor can help draw you into the experience better than smaller monitors can, even if the sides are sometimes blacked out rather than fully being used to show the game you're playing. For instance, playing Diablo IV on an ultrawide monitor allows you to see more of the world at once, including enemies and turns in the path that are further away from your character.
