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.
Sceptre Incorporated
In 2013, Sceptre added Mobile High-Definition Link (MHL) to many of its LCD TVs. This technology allows users to connect smartphones and tablets to the TV via a cable that has an HDMI connector on end and an MHL connector on the other.
Sceptre designed its first 4K UHD TV in late 2014 with a 49-inch model, the U500CV-UMK. Currently, its 4K models come equipped with HDMI 2.0, HDCP 2.2 and MEMC 120. At 60 frames per second, HDMI 2.0 transports 4K content at double the speed of 1.4. Motion Estimation/Motion Compensation (MEMC) smooths out blurring as objects are in motion on the screen, at approximately 120 frames per second. This feature is highly effective during action sequences, such as the kind found in sports, but has less relevance during fictional programming, such as sitcoms, when people and objects are frequently stationary or not moving at high speeds.
