THX Certified 4K Display

Even if you are unfamiliar with THX, you'll almost certainly be familiar with Star Wars creator George Lucas. Not long after the Star Wars trilogy hit the screens, Lucas began exploring how to get the best possible quality from what initially started as sound and audio, discovering that many cinemas couldn't cope with the intricacies and level of detail that his films contained.

Over the years this has developed into an integral testing process for both cinema, DVD, Blu-ray and now the world of Ultra-HD Televisions.

With these tests in mind, you can be safe in knowing that you are getting the ultimate Ultra HD experience from your Panasonic Smart TV. Here are a few varying factors that can add to the way you experience 4k and HD.

You may have come across the abbreviation THX, mainly if you are keeping your finger on the pulse of all things HD in the television and film world and perhaps wondered what it stands for. Over the last year or so, THX displays have started leaking their way into the Panasonic TV market, and we thought it was about time we shed some little light on what these displays are all about.

As displays grow in their physical size or our proximity to them is lessened, the decisive factors of higher resolutions such as 4K and HD start to become easier to identify. This is based merely on the number of pixels it takes to make up a display screen. A standard 1080p HD television has a total of approximately two million pixels which together display the on-screen image. This is true regardless of screen size, meaning that a 46-inch 1080p display and a 70-inch 1080p display both have approximately two million pixels. However, when you divide these two million pixels into the surface area for a 46-inch television, you end up with about 2,700 pixels per square inch. When you compute the same figure for a 70-inch TV, the number drops to approximately 1,780 pixels per square inch. In simplest terms, it is easier to see pixels on a larger screen than on a smaller screen because pixel is larger. The larger the screen, the more likely you’ll recognise the image clarity and sharpness benefits of Ultra HD displays.

Your eyesight, quality of the display itself, and various other factors influence the point at which a person can distinguish individual pixels on a screen of a given size. Nonetheless, for the overwhelming majority of consumers with a home television viewing distance of six feet or higher, the benefits of increased screen resolution will be recognised when viewing 4K content on a display 55 inches or larger.
