Understanding Smart TV Picture Resolution

A smart TV is basically a television set integrated with internet and interactive “Web 2.0” features that enable users to stream music and video contents, and as well browse the internet. A smart TV gives you access to a world of content beyond live TV channels.

Smart TVs come with different screen resolutions, which include UHD, 720p, 1080p, 4k, 8k, among others. We will be discussing in details the different types of picture resolutions.

What is picture resolution?

When shopping for a new TV, one very important data (number) you should consider after screen size and price is the resolution.

Picture resolution refers to the number of pixels that compose the picture on the TV. Old non-smart TV and many 32-inch TV models available today have over a million pixels (720p). Recently made(typically 49-inches) and slightly larger TVs have a little over 2 million pixels (1080p). Bigger TVs (50-inches and above) have over 8million pixels(for 4k ultra HD). And the latest and ridiculously expensive TVs have over 33 million pixels (8k).

It is important to note that resolution is not the most important ingredient in picture quality, just because your smart TV has a higher resolution doesn’t mean it will look better than a smart TV with a lower resolution. High dynamic range (HDR), a better overall contrast ratio, better color, and picture resolution, all combine to make picture quality high.

Ultra HD (4k)

4k resolutions are the most common for TVs; they create images using 8.3 million pixels. When it comes to TVs, 4k and ultra HD are referring to the same resolution. The effective resolution is 3840 pixels wide by 2160 high (3840 x 2160). With all these many pixels on the screen, the brightness of the colors, the sharpness of the images are greatly enhanced. It also allows images to be seen in greater clarity.


Before “4K” became common, a 2k resolution was standard on most TVs. It’s pretty much just a cinema resolution. Most digital cinema projectors used in theaters are 2k resolutions. Its 2048 pixels wide and there’s no vertical resolution specified by the digital cinema initiatives (DMI).

1080p or Full HD

Full HD TVs are ideal for showing Blu-ray DVDs, video games and Freeview HD, which are often produced in higher resolution. With a horizontal resolution of 1920 pixels wide by 1080 high (1920 x 1080), they have the potential to offer greater picture clarity, as they display footages that have been developed in full HD.


8k refers to screens with over 8000 pixels width. They are also known as UHD-2 and is the current highest Ultra high definition television in the world of digital television and digital cinematography.

In the future, resolutions might no longer be relevant. Technologies like MicroLED have found a way to separate size and resolution.
