4K resolution
The term "2160p" could be applied to any format with a height of 2160 pixels, but it is most commonly used in reference to the 4K UHDTV resolution of 38402160 due to its association with the well-known 720p and 1080p HDTV formats. Although 38402160 is both a 4K resolution and a 2160p resolution, these terms cannot always be used interchangeably since not all 4K resolutions are 2160 pixels tall, and not all 2160p resolutions are ≈4000 pixels wide. However, some companies have begun using the term "4K" to describe devices with support for a 2160p resolution, even if it is not close to 4000 pixels wide. For example, many "4K" dash cams only support a resolution of 28802160 (4∶3); although this is a 2160p resolution, it is not a 4K resolution. Samsung also released a 51202160 (64∶27) TV, but marketed it as a "4K" TV despite its 5K-class resolution.
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.
