4K resolution, also called 4K, refers to a horizontal display resolution of approximately 4,000 pixels. Digital television and digital cinematography commonly use several different 4K resolutions. In television and consumer media, 38402160 (4K UHD) is the dominant 4K standard, whereas the movie projection industry uses 40962160 (DCI 4K).
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.
