We explain the difference between HDX and HD with table. The world of screens is full of new technologies. Each advance makes the greatest a thing of the past. With each new technology, a new name is added to the list.
HD, HDX, and UHD are among many of these advancements. Although we use the terms interchangeably, there is a strict difference between each of them. Also, HDX and HD are not the same, although it seems like their name.
HDX stands for High Definition Extra. It includes many technologies that work simultaneously to provide a high-level user experience. Provides a minimum display of 720 horizontal lines.
HD means high definition. It gives a minimum resolution of 720 pixels. The minimum horizontal line display is 480.
The difference between HDX and HD is that HDX offers the minimum resolution of 1080 pixels and the best video and audio quality, while HD offers a minimum resolution of 720 pixels and better quality than SD.

What is HDX?
HDX is a modern display technology developed by Vudu. It offers excellent audio and video streaming services. It is basically an upgrade from HD technology.
It stands for High Definition Extra. It offers a screen of 720 horizontal lines.
It offers a resolution of approximately 1080 pixels and more than 1GB of memory. Encodes video at twice the bit rate of HD.
Also, it has the ability to vary bit rates based on video scenes. Keep the video transmission speed at 24 frames per second.
The HDX display uses the HDX protocol. There are servers, preloaded with programs, that communicate with users. This communication is based on Adaptive Technology.
Adaptive technology uses a compression algorithm to improve display. In addition, its contactless functionality offers a seamless experience to LAN and even WAN clients over long distances.
However, HDX also has some downsides. It takes more time to download a video than to stream it. Also, it is not device independent. It cannot offer good resolution on a device that does not support it.
What is HD?
HD means high definition. It’s a display technology that has eclipsed the mainstream SD.
It was conceived in 1936. However, at that time, the resolution was only 30 lines. High-definition television service in Great Britain began in November 1936.
The NHK Broadcasting Corporation of Japan began its research on HD technology in 1964. In 1972 it created a new system called NHK color.
The Society of Television and Cinematography Engineers became the standard authority for HD technology in the world. In its beginnings, it was directed by Charles Ginsburg.
Most HD systems from the 1970s have been converted to today’s SD systems. Initially, analog systems were used for HD transmission. However, it was later superseded by digital compression techniques.
Compression techniques were used because uncompressed video used a lot of bandwidth. HD quality video downloads faster.
The special feature of the HD screen is that it does not depend on the size of the screen. As long as the pixel measurement is 1280 × 720, the screen would be called HD.
Full HD or FHD is an improvement on HD display technology. It has the pixel size of 1920 × 1080 pixels. Full HD has many advantages. These are ease of loading, better image quality, and less eyestrain. However, it faces the same problem as the HDX screen. Its visual effects cannot be enjoyed on an unsupported device.
Main differences between HDX and HD
HDX and HD are display technologies. They improve the visual and auditory effect of a video.
The main differences between the two are:
- HDX stands for extra high definition, while HD stands for high definition display.
- The HDX screen has more than 720 horizontal lines, while the HD screen has more than 480 horizontal lines.
- The HDX display offers a resolution of 1080 pixels, while the HD display offers a resolution of 720 pixels.
- The HDX screen offers the best video and audio quality, while the HD screen has a better quality than the SD screen.
- The HDX display occupies more than 1 Gigabyte of memory, while the HD display occupies more than 1 Terabyte of memory.
Final Thought
Our television screens, computer monitors, and smartphones are examples of display devices. They are so called because they present information in visual form.
HDX and HD are display techniques that power display devices. While HDX offers the best visual quality, HD offers immense advances over SD displays.
HDX has a resolution of 1080 pixels compared to HD’s 720 pixels. Also, the HDX screen has more than 720 horizontal lines, while HD has more than 480.
However, it should be noted that at one point, SD technology was also called HD. Over time, display technologies have evolved. So we don’t just have SD and HD as options.
It is a known fact that a better view of the screen causes less strain on the eyes. The HD + offers this same feature.
In 2018, about 31% of Americans had an HDTV at home. This shows that HD has been transformed from a luxury to an ordinary household staple.
