If you recall, last year, Huawei CEO Richard Yu effectively said that he's not in favor of QHD displays on smartphone as he thinks it's difficult for humans to distinguish between Full HD and QHD displays. However now, he seems to have changed his mind.
Huawei's latest P9 - comes with full HD display
And the reason is VR. "Last year I would certainly not buy a 2K device as the power consumption was high and the difference to my eyes non-existent. But now I have changed my mind and my next phone will be 2K as I like VR!," he noted in a post on Weibo.
It's worth mentioning that by 2K, he probably means QHD as the former has never been a phone resolution. Also, in case you missed, Huawei's change of heart comes nearly a week after the company announced its own VR headset.
"QHD: Quad HD, 4x HD (720p), meaning 2560x1440. beccause UHD has two version 4K ..." you lost me there
That had more to do with usage differences than changing resolution.
