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. | Higher resolution means sharper, clearer and more detailed images.

For truly immersive Virtual Reality, 4K resolution (3840 x 2160) or higher is required. According to [[Plamer Luckey]], found of [[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. | For truly immersive Virtual Reality, 4K resolution (3840 x 2160) or higher is required.
