The technologies of 4K and HDR have changed TV viewing around the world. It has become more immersive and cinematic. Such an experience can only be created by extremely high resolution and high definition. What the viewer’s experience then is akin to watching the real world through an open window. The colours are equally vibrant and every object distinctly visible.

4K Technology
Most smart TVs come with 4K resolution now as opposed to the slowly fading 1080p or HD resolution. 4K refers to the pixel density of the current smart screens. The fundamental idea behind this technology is that screen graphics can be enhanced by packing pixels in close density.
Thus in a 4K TV, 3840pixels are horizontally packed and 2160 pixels are vertically packed making for a total of 8.3million closely packed pixels. This is 4 times the pixel density of the traditional full HD. While the difference in picture quality is glaringly apparent in big screen smart TVs like the 40 inch hd smart tv, the presence of this technology even in the 32-inch TV size makes this technology affordable. Since the pixels in the low-resolution Full ...
... HD TVs are smaller in comparison to the high-resolution smart TVs, viewers can enjoy an immersive experience without individual pixels becoming visible at close range. 4K TVs also provide an immersive experience when watched from any distance.

HDR Technology
HDR or high dynamic range refers to the technology that enables the creation of an almost real-life like image. This effect is achieved by bringing a balance in the range of colours especially the areas that are lighted and those that are dark. For example, HDR images even show the shadow details occurring because of a bright sky.

The contrast in HDR is so precisely adjusted that it is possible to establish a perfect balance between the range of colours displayed and the light and dark areas. Thus, even challenging backdrops like the sunsets can also be displayed with alarming clarity. This image clarity and sharpness providing an almost 3D effect to a 2D image is the primary reason why people prefer to buy 40 inch led tv India.

Effects of 4K HDR
Bringing real-life effect to an image is the ultimate goal of 4K. HDR too seeks to achieve the same goal. While 4K does this by packing in pixels more densely, HDR achieves this by creating the perfect contrast between images. HDR makes the screen luminosity highly dynamic thereby adding more details and contrast to an image. Along with the display contrast ratio, the HDR also seeks to expand the colour ratio so that the whole gamut of the colour palette is distinctly visible. All this combines to make the image more realistic and real-life like.

The viewer gains by the combination of 4K with HDR by getting to see a vibrant, detailed and sharp picture that also has an increased depth. However, the actual effect is only visible when 4K content is watched. With most networks streaming an increased amount of 4K content in recent times, the viewer feels justified in procuring a 4K HDR smart TV despite the 40 inch led tv price. Recent developments have resulted in 4K HDR Smart TVs becoming more affordable than they were before.
