Lack of a matte display option was one of the pain points of the Dell XPS 13 9370, making it a tad difficult to use under direct light or outdoors. We had a chance to speak to some panel manufacturers during Computex 2018 and luckily, they tell us that the upcoming XPS 13 9380 will feature a matte display option. Also, based on the information thus far, we get to speculate that HDR panels are a likely possibility in the upcoming XPS lineup.
