Xbox one X and one S will get 1440p

Xbox one X and S are often regarded for its most impressive features. It uses console's additional power to provide improved graphical quality to your games when played on full HD(1080p) displays.
Now, the xbox one x downscales 4K signals exclusively to 1080p meaning those with QHD(1440p) monitors are left playing at much lower resolution than their screens are capable of-but not for long.
Though support for 1440p monitor was first announced last year, Kevin Gammill, program manager for Microsoft's Xbox  platform partner. Group has now revealed via twitter that it's likely to arrive in the near future.
