4K resolution
So while 4K UHD sounds like it has a pixel structures with 1/4 the area of 1080p, that does not happen with pixel shifting. Only a true 4K projector offers that level of resolution. That's why "true" 4K projectors cost so much more than 4K UHD projectors with otherwise similar feature sets. They produce smaller pixels, finer resolution, no compromising of detail or color from overlapping pixels. By comparison, the slight difference in aspect ratio between DCI and 3840×2160 pixel displays without overlap is insignificant relative to the amount of detail.
PlayStation 4
On June 10, 2016, Sony confirmed that a hardware revision of the PlayStation 4, rumored to be codenamed "Neo", was under development. The new revision is a higher-end model that is meant to support gameplay in 4K. The new model will be sold alongside the existing model, and all existing software will be compatible between the two models. Layden stated that Sony has no plans to "bifurcate the market", only that gamers playing on the Neo will "have the same experience, but one will be delivered at a higher resolution, with an enhanced graphical experience, but everything else is going to be exactly as you'd expect". The high-end console was publicly revealed on September 7, 2016, as PlayStation 4 Pro. At the same time, Sony unveiled an updated version of the original PS4 model with a smaller form factor.
