Resolution: Difference between revisions

[[Resolution]] is the number of pixels that can be displayed. Resolution is usually shown as width x height. For example, a resolution of 1920 x 1080 means that it has 1920 pixels as its width and 1080 pixels as its height. A 1080p HDTV has the resolution of 1920 x 1080.

Higher resolution means sharper, clearer and more detailed images. Low resolution can cause the pixels to become visible to the human eyes. This is especially evident in [[Virtual Reality]] [[HMD]]s because the user's eyes are positioned very close to the display. Low resolution and low [[PPI]], pixels per inch, can cause the user to feel pixelation and feel like he or she is looking through a [[screen door]]. For optimal immersion, pixels on the display have to be dense enough to be invisible to the human eyes when viewed from very close range.  

For truly immersive Virtual Reality, 4K resolution (3840 x 2160) or higher is required. According to [[Plamer Luckey]], found of [[Oculus Rift (Platform)|Oculus Rift]], pixelation will not go away completely until at least 8K resolution (7680 x 4320) per eye is achieved<ref>http://arstechnica.com/gaming/2013/09/virtual-perfection-why-8k-resolution-per-eye-isnt-enough-for-perfect-vr/</ref>. As of 2015, non of the [[VR Devices|VR HMDs]] have 4k or greater resolution.
