"Optimize Graphics Instantly on Xbox Series X with One Setting Change"

Xbox Series X users can significantly enhance their console's graphics by changing the display setting to 1080p, as demonstrated by YouTuber ChadReddings. Further improvements can be made for 4K TV owners by optimizing settings and calibrating the TV. However, it's important to note that the 1080p resolution change is only beneficial for those with a 1080p TV, and not for higher resolutions like 4K or 8K.
