What is 4K Ultra HD TVs, 4K HD

A UHD or 4K display

is one with at least 8 million active pixels. For televisions, that resolution has standardized to 3,840 by 2,160. Digital cinema 4K (the resolution in 4K movie theaters) is slightly higher at 4,096 by 2,160. However you define it, it’s four times the number of pixels on a 1080p display, and over 23 times the resolution of standard definition television.

For starters, 4K HD is obviously much better than 1080p. In the space that a 1080p TV holds a pixel, a 4K TV of the same size can hold four. That makes for a significant jump in clarity, assuming you have native 4K source material to watch in that resolution.

What is Full HD, Full high-definition

What is Full HD?

1080p (1920×1080 px; Full HD or FHD and BT.709) is a set of HDTV high-definition video modes characterized by 1080 horizontal lines of vertical resolution and progressive scan, as opposed to interlaced, as is the case with the 1080i display standard. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as Full HD, to contrast 1080p with 720p resolution screens.

1080p video signals are supported by ATSC standards in the United States and DVB standards in Europe. Applications of the 1080p standard include television broadcasts, blu-ray discs, smartphones, Internet content such as YouTube videos and Netflix TV shows and movies, consumer-grade televisions and projectors, computer monitors and video game consoles. Small camcorders and digital cameras can capture still and moving images in 1080p resolution.

 

What is Smart TV

A smart TV is a digital television that is connected to Internet, storage-aware computer specialized for entertainment.

Smart TVs are available as stand-alone products but regular televisions can also be made “smart” through set-top boxes that enable advanced functions.

Besides being able to receive cable and satellite or over the air (OTA) transmission passively, smart TVs are outfited with extra hardware and connection types, as well as a TV operating system with a GUI. These adaptations allow viewers to access and control features for streaming content from Internet video services and connected devices.

Typically, smart TVs support Ethernet, Wifi, USB, Bluetooth and flash memory cards from digital cameras, as well as coaxial cable, HDMI and other audio-video connections. Along with the OS and apps, the connectors enable on demand video services and access to pictures, music and video on connected storage devices. Smart TV apps allow connection to websites like Youtube, Netflix, Hulu and Vimeo and social media sites such as Facebook and Twitter.

What is HDTV

HDTV is High-definition television system providing an image resolution that is substantially higher than that of standard-definition television.

HDTV may be transmitted in various formats:

1080p: 1920×1080p: 2,073,600 pixels (~2.07 megapixels) per frame
1080i: 1920×1080i: 1,036,800 pixels (~1.04 MP) per field or 2,073,600 pixels (~2.07 MP) per frame
Some countries also use a non-standard CEA resolution, such as 1440×1080i: 777,600 pixels (~0.78 MP) per field or 1,555,200 pixels (~1.56 MP) per frame
720p: 1280×720p: 921,600 pixels (~0.92 MP) per frame

The letter “p” here stands for progressive scan, while “i” indicates interlaced.

When transmitted at two megapixels per frame, HDTV provides about five times as many pixels as SD (standard-definition television). HDTV provides a more desirable picture because of the increased amount of pixels, allowing images to be changed up to 60 times per second compared to SD at 30 times per second. This produces a clearer picture due to progressive scanning.

What is motion blur?

What is motion blur?

Motion blur is the apparent streaking of rapidly moving objects in a still image or a sequence of images such as a movie or animation. It results when the image being recorded changes during the recording of a single exposure, either due to rapid movement or long exposure.

Screen motion blur, also called HDTV blur and FLATSCREEN motion blur, is a set of many different artifacts that is frequently available on modern consumer hi-definition television set sets and smooth panel displays for computer systems.
Many motion blur factors have existed for years in film and video (e. g. slow camera shutter release speed). The emergence of digital video, and HIGH DEFINITION TV display technologies, introduced many additional factors that now contribute to motion obnubilate. The following factors are often the primary or supplementary reasons behind perceived motion obnubilate in video. In many cases, multiple factors can occur at the same time within the complete string, from the original multimedia or broadcast, all the way to the recipient end.

 Pixel response time on LCD displays (motion blur caused by gradual pixel response time)
More affordable camera shutter speeds common in Hollywood production motion pictures (blur in this article of the film), and common in miniaturized camera detectors that require more light.
Blur from eye monitoring fast-moving objects on sample-and-hold LCD, plasma, or microdisplay.
Resolution resampling (blur due to resizing image to fit the native resolution of the HDTV); not a movement blur.
Deinterlacing by the display, and telecine control by studios. These techniques can soften images, and introduce motion-speed irregularities.
Compression artifacts, within digital online video streams, can contribute additional blur during fast movement.

What is motion blur? Motion blur has recently been a more severe problem for LCD displays, anticipated to their sample-and-hold characteristics. Even in situations when pixel response time is very brief, motion blur remains problems because their pixels continue to be lit, unlike CRT phosphors that merely flash in brief. Reducing the time an LCD pixel is lighted, can be accomplished via killing the backlight for part of an invigorate.[4] This reduces motion blur due to eye tracking by reducing the time the backlight is on. Additionally, strobed backlights can even be combined along with motion interpolation to minimize
