Ultra-High-Definition (UHD) TVs – Extra resolution at extra price, but what else is extra?

We know that the higher the resolution, the better is the image quality. From this standpoint, a UHD TV, popularly also known as 4K TV, is a good buy certainly but not under all conditions. Surprised? Well, to start with, the full benefit of 4K isn’t really evident until you get at least a 50-inch screen. As you go 50 inches and up, it becomes appreciably more important to get that higher resolution as it adds better definition and clarity to the picture at that size. Let’s suppose you have that 50-inch HD TV and you upgrade to 4K: you are cramming four times the number of pixels into the same amount of space. That makes for a denser picture with finer detail. On smaller TVs (under 40 inches), it’s difficult to see the difference between HD and 4K and one need not go with the latter option for these. The following guide will help you see what to expect from your UHD TV and the various parameters that you may want to assess. We also compared various models (40 to 55 inches) on some basic features.

It is important to have connectivity to the HD transmissions of the channels you want to receive. Another thing to know is that movies and TV shows need to be optimized for 4K in order to take full advantage of the higher resolution.

Also, bear in mind that paying for more pixels doesn’t guarantee a better picture. Colour accuracy, smooth transitions between colours, and blacks that don’t look muddy or lose detail are far more important. More pixels may actually make it harder for the TV’s picture processor to deliver a good image.

4K has a resolution of 3,840 x 2,160 pixels, basically packing 8.3 million pixels into a screen. That’s four times more pixels than in a full HD television. Remember, though, that it’s not about sharpness, it’s about letting you see more detail and texture. The advantage of a higher-resolution screen is that you can sit closer and still get lots of detail in the image.

That said, there are more things going for a UHD TV than not. The extra resolution and increased pixel density means you can sit closer to your TV without spotting individual pixels. Almost all 4K TVs support the high-dynamic range (HDR) feature (apparently this technology expands the TV’s colour palette by displaying high levels of contrast between bright and dark colours).

Another reason you may decide to make the 4K TV leap: Standards for some UHD features, including HDR and a wider palette of colors, have now been set, so you don’t have to worry about missing out on a new important feature.

It’s a good thing that the number of 4K movies and shows you can watch in ultra-high definition is constantly increasing. And what’s more, the initial price barrier has dropped substantially over the past few years, making it both attractive and accessible.

So, if you have set your mind on it and have the budget, get that 4K TV by all means. Here is a compilation of the things you may want to know before making the purchase.
