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.
SES S.A.
In May 2018 SES broadcast an 8K television signal via its satellite system for the first time, as part of its Industry Days conference at the Luxembourg HQ. The 8K demonstration content, with a resolution of 7680x4320 pixels, a frame rate of 60 frames per second and 10-bit colour depth, was encoded in HEVC and transmitted at a rate of 80 Mbit/s via the Astra 3B satellite.
