The LG G3 may be the first major handset with a QuadHD display if the latest leak is to be believed.
Twitter tipster @evleaks has dug up a User Agent profile from one of LG's official websites, detailing a device going by the name LG D850 which sports a resolution of 1440 x 2560 (QuadHD in other words).
Now we don't know for sure that the LG D850 is the LG G3, but with a screen like that it's got to be a top end device and being on an official LG website it's likely to be a real thing.
Supposedly the handset will sport a 5.5-inch display, which combined with the rumoured QuadHD resolution would give it a pixel density of 534 pixels per inch.
It's questionable whether the human eye will even benefit from all those extra pixels, but as a bullet point for the box that could certainly make it stand out from the Samsung Galaxy S5 and Xperia Z2.
