When purchasing a home TV, you will see all its specs, such as 'come with 4K UHD’. While it implies that the device supports high-quality streaming, what differs from other resolutions? Does it mean an HD TV is not enough? If you are unsure which one to bring home, this article will walk you through the difference between Full HD vs. 4K and why they are important to distinguish when buying a TV or any streaming gadget.

HD Vs. 4K

Part 1. What is HD Resolution

The term resolution means the number of pixels in an image. A pixel is a small detail that the naked eye cannot see. But in numbers, the more pixels a video has, the more detailed and higher its resolution.

720p and 1080p are already HD resolutions, surpassing the standard definition. There is no standardized meaning of HD, but a video is considered an HD when it has more than 480 vertical scan lines for North America or 576 vertical lines for Europe. Although 1920 x 1080p is already an HD, playing a 1080p video with this resolution on a 4K device will not improve the quality. Thus, get a TV which is compatible with the HD videos.

Part 2. What is 4K Resolution

In the same way as Full HD, 4K is defined as the horizontal display resolution with about 4,000 pixels. This means it has a resolution of 3840x2160, totaling over eight million pixels. Since it is higher in resolution, the picture becomes sharper. When streaming a 4K video, it requires a 4K medium with bandwidth between 10MBPs and 20MBPS. To stream 4K content online smoothly, connecting to a 15 Mbps internet network is suggested.

When it comes to HD vs. Full HD vs 4K, the latter is much more specific to its supported codecs. For example, a video must have H.265 and VP9, which are standard video codecs that are specifically made for video compression. These codecs are also best for 4K upscaling, as they meet the required bandwidth and quality level.

Now, let’s see how these resolutions differ in other forms. It is easy to say that they already provided higher resolution for TVs, cameras, and other devices. However, it is best to learn more about their originality and supported data in terms of many aspects.

4K vs HD Comparison


Of course, the resolution will be the most significant difference between 4K vs HD, as they consist of a distinct number of pixels. But to make it clear, HD does not only stay in one resolution, but it can range from 720p to 1080p. Meanwhile, 4K ranges from 2160p to 3840p and can go further up to 4320p. If a TV has a 4K resolution, this means it has double the pixels of an HD TV. You can upscale 1080p to 4K if you need a super clear vision.


Just because something is of high resolution does not mean it is better in visuals. Sometimes, it is recommended to have HD as it is the standard for Blu-rays, while the other resolution can only support 4K videos. Still, it has the tendency to lower the video quality if it's incompatible.


As you may know, televisions, cameras, and other devices that support a 4K or HD resolution can be offered at a higher price. In this case, gadgets with HD resolution are way cheaper than 4K ones, but they are more reliable for standard media playback and editing.


When it comes to formats, HD is more open to video editing with various formats. Of course, 4K supports popular formats like MP4, MKV, and AVCHD, but HD can be completely upscaled and edited by different programs. In the case of 4K, it is difficult to navigate its output settings without lowering the quality and other elements.


HD and 4K are in high definition, but you will mainly discover that choosing the suitable resolution helps avoid blurring the quality. At some point, if you have a console that is capable of 4K gameplay, using an HDTV might not display the visual quality you are expecting. On the other hand, HD has more opportunities to connect to other devices with the intention of showing the best quality.
