4K resolution
This resolution is used mainly in digital cinema production, and has a total of 8,847,360 pixels with an aspect ratio 256135 (≈1910). It was standardized as the resolution of the 4K container format defined by Digital Cinema Initiatives in the Digital Cinema System Specification, and is the native resolution of all DCI-compliant 4K digital projectors and monitors. The DCI specification allows several different resolutions for the content inside the container, depending on the desired aspect ratio. The allowed resolutions are defined in SMPTE 428-1: The DCI 4K standard has twice the horizontal and vertical resolution of DCI 2K (), with four times as many pixels overall.
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.
