Why do my graphics look so bad?

My Xbox one s graphics look terrible now on every single game. My Xbox is always in standby mode and when ever I played a game I never closed it then I turn off my Xbox because when I turn it on I start from where I left off instead of having to wait through loading times. And I left my Xbox in standby mode with a game still running . Now my graphics on every single game look extra pixelated and blurry even the resolution. and I already tried fixing it in the display settings but I didn’t have any luck

It won’t let me send a picture but do you have any methods I can try to fix it?
