4K resolution
As noted above, DCI 4K is 40962160, while 4K UHD is 38402160, producing a slight difference in aspect ratio rather than a significant difference in resolution. Traditional displays, such as LCD or OLED, are 3840 pixels across the screen, with each pixel being 1/3840th of the screen width. They do not overlap—if they did, they would suffer reduced detail. The diameter of each pixel is basically 1/3840th of the screen width or 1/2160th of the screen height - either gives the same size pixel. That 38402160 works out to 8.3 megapixels, the official resolution of 4K UHD (and therefore Blu-ray UHD discs).
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.
