[SIZE=7]Xperia 1[/SIZE]
The new Xperia 1 was made with the advanced technology from Sony’s professional monitors, cameras and audio devices, to deliver the best experience in a smartphone. It features the world´s first 21:9 CinemaWide™ 4K HDR OLED display and a pro-quality triple lens camera.
4k is good when implemented well, but also on a screen like a 13 inch or bigger. what really matters is the technology behind the lcd. if its a tn panel its crap unless when its for fast gaming and not really pleasant virtual reality. if its IPS 4k its better. if its IGZO ips tft its best. if can be 4k but bad tech.
