A new rumor claims that the OnePlus 8 Pro will feature a 120Hz display. While this rumor comes seemingly out of left field, it's not out of the question for OnePlus to continue to push high-refresh rate displays in its handsets. Considering the success of the OnePlus 7 Pro's 90Hz panel, a 120Hz display may give the OnePlus 8 Pro the edge it needs over the competition.
