Basic Differences Between a UHD or 4K HD TV and an HD TV

In today’s day and age, almost everyone owns a television set. Very rarely will you find a house that doesn’t have any television set. Right from the Black and White television sets to the latest technological advancements in this field, the humble television surely has come a long way.

The first successful transmission of visuals happened in the 1920s by a Scottish engineer, John Logie Baird. Colour televisions were first successfully tested in the 1940s by a Hungarian-American engineer, Peter Carl Gold mark; the 1960s saw the first international transmissions being done; the 1980s saw Stereo TV broadcasts being approved and run, and it was in the 1990s that HDTVs were accepted as the norm and more than 1 billion homes across the World had a television set.*

However, now that we look at a television set, it is way more advanced than the first television sets that most people owned. Today, there are broadcast agencies all across the World producing and relaying shows for everyone. Internet backed TV and watching shows over the internet too has become a common occurrence now. The latest television sets are Smart TVs, backed up with exceptional features giving you amazing audio and video quality.

So, what are the different kinds of TVs and what should you keep in mind when selecting the most ideal one for your living room. Read on, below as we list the basic differences between a UHD Smart TV and an HD Smart TV to help you make the right choice.

What does UHD and HD even mean?

HD stands for High Definition and UHD stands for Ultra High Definition. These are basically different kinds of screen resolutions. TV resolution basically refers to the number of pixels that come up when you view something. A pixel stands for the smallest light point that makes up the image on a screen. So, the more the pixels on the screen, the clearer will your picture be and the higher will be the screen resolution.

HDTVs have been in use since a very long time now. Ultra HD or 4K HD came into the scene very recently and these are slowly, but surely, changing the way we view it all. If you went out to buy a HDTV today, you will, in all probability, end up buying a 4K HD TV.

How is TV resolution measured?

A TV screen resolution is measured by counting the number of pixels horizontally and vertically. Usually, it is the vertical pixels that define the resolution of the TV and whether it is an SD (Standard Definition), HD (High Definition), or a 4K HD TV! So, what are these measurements that define the picture quality. Let’s see below:


  • Standard Definition (SD) - A SD TV is “a digital television (DTV) format that provides picture quality similar to a digital versatile disk (DVD).” ** A generic SD TV will have measurements like 704x576 pixels, which equals 4,05,504 pixels in all.

  • High definition (HD) - An HD TV “describes a television system providing a substantially higher image resolution than the previous generation of technologies.” *** The basic HD TV provides at least 1280x720 pixels, which equals 9,21,600 pixels. It is also commonly referred to as the 720p TV, which is also known as the HD Ready TV. A Full HD TV has a screen resolution of 1920x1080 pixels (commonly known as 1080p) that equals 20,73,600 pixels. Since the pixels size is so huge, so is the screen size allowing you to enjoy amazing colours, better picture clarity, and more lifelike images on the screen.

  • 4K HDTV or Ultra High Definition (UHD) - The UHD TV “is simply a higher resolution than HD, even the smallest details stand out - such as the hair or fabric of a cotton shirt. The 3840-pixel number is close to 4,000, which is why UHD TVs are also known as 4K TVs.” **** These TVs have a higher resolution of at least 3840x2160 pixels that equals 82,94,400 pixels which is double the resolution size of a Full HD TV.

  • These are some of the basic differences between the various kinds of TV screen resolution sizes. So, the higher the pixels, the clearer is the picture and the high-quality images allow you to see your favourite TV series, movies, or sports in better depth and with greater clarity.
