game stretches when i play on ultrawide monitor

you see, I have a ultrawide monitor with an aspect ratio of 21:9 and when i play games with it, it extends the view of the game making everything visible on the angle your'e looking at, but when i play skate, instead of extending the view, it stretches the game, i think this is an error because when i change the display of the game to borderless fullscreen or fullscreen, it extends the game and it dosent look like its stretched out, but when i join a party with my brother or with my friends or quit and play the game, it stretches the game once again and not extending the view, and theres also a problem with borderless fullscreen, when i play the game, the game blacks out, the only way to bring the window back is by pressing the start button, but it is temporary because after 5 seconds, it blacks out again, so its very hard for me to play the game when the game stretches or when it blacks out, EA please fix your game.
