The Xiaomi Mi 11 Ultra smartphone has not managed to enter the top 10 global ranking for display in a recent DxOMark test. The expensive phone performed well overall but was shy of the performances produced by rivals such as the Samsung Galaxy S21 Ultra 5G and OnePlus 9 Pro. The Mi 11 Ultra achieved the same score as the cheaper Xiaomi Mi 11.
