Here at Displaypoint, we sell ultra high-definition 4K display screens. But what is 4K and what exactly makes it different to high definition?
In this blog we will cut through the tech jargon and attempt to explain what exactly you are getting when you buy a 4K display.
High definition has been with us for years and it covers any screen that has a 1080p resolution. That is 1920 pixels by 1080 pixels. Now there's ultra-high definition (UHD) or 4K display too. And to qualify, 4K displays have to sport at least 8 million active pixels on its screen.
For screens such as TVs and displays, this resolution has been standardised to 3,840 pixels by 2,160 pixels. For larger screens, such those used in cinemas, this criteria has been raised to 4,096 pixels by 2,160 pixels. Essentially, then, it is four times the number of pixels found on a 1080p display and more than 23 times you get from an average, standard display.
But how is 4K different from 1080p in practical terms? Firstly, the image quality is that much sharper and can output a much clearer image than an HD display. This is because a 4K display holds four times the number of pixels in an area in which a 1080p HDTV holds one.
Due to the resolution being a lot higher than HD displays, more bandwidth is required for displays to transmit. The HDMI 2.0 connection standard was developed specifically to support 4K. The connection also brings a further benefit of being able to stream 2160p video at 60 frames per second. While old HDMI connections could work, it would not be able to stream at that framerate.
What's more, 4K displays are also able to take advantage of an upconverter. This enables them to display 1080p and 720p resolutions. However, what makes this upconverter so good, is that it uses edge smoothing and noise reduction algorithms. This enables the display to produce a sharper picture. While previous resolutions were less apparent in the clarity of images, in the current market, with displays increasingly becoming 55 inches and above, the jump in clarity and detail is becoming more and more significant.
Finally, the amount of streaming services that are beginning to churn out 4K content is starting to work up a head of steam. Both Amazon and Netflix now allow you to stream 4K content (providing you have a fast internet connection) and social channels such as Youtube are beginning to offer 4K video for everyone.
4K has gone from a fancy technology that was prohibitively expensive to being a viable technology that is only increasing in demand and usage. The technology is rapidly becoming standardised and displays are a lot more affordable than what they used to be.
So why not take a look at our 4K UHD displays and see which one takes your fancy?
