A:AnswerI haven't found how to brighten the screen. But go to Settings and type color change or display change in the box at the top of the box. You will be given many choices to adjust the color if this fixes your problem. Other than that, I don't know. But the Geek Squad at Best Buy are VERY helpful!

A:AnswerThis model is lacking dedicated graphics which would provide the smoothest gaming experience, but yes, it can run the Sims 4.
