Is 4K really worth the upgrade?
You’ve probably seen the new TVs at your local electronics store, some people claim they can’t tell the difference between HD and 4K, here is a brief article explaining the differences between TV resolutions.
First of all let’s talk about the units of resolution, those tiny dots of light on screens, each one of them is called a pixel. The more pixels you can fit into your screen, the better your images can look, for example modern smartphones have HD (high-definition) screens with at least 1920 x 1080 pixels, that is over 2 million dots of light in a single screen.
What is 4K?
4K is a resolution standard with 3840 x 2160 pixels, that is over 8 million dots of light in a single screen. 4K allows the viewer to experience crisp and clear images on a compatible screen. New cameras and most new smartphones can record video in 4K.
DVD vs. 1080p vs. 4K
Here is an easy way to understand the difference between the different resolutions.
On this image the closeup shows the difference between standard definition DVD, HD 1080p and Ultra HD 4K.
Time to upgrade?
4K is an amazing technology but if you have a 50-inch TV and you view it at a distance of 8 feet, it is really difficult to notice the difference between high definition and 4K. Unless you are a movie-lover or a film maker, the best thing to do is wait until the technology drops in price and becomes the standard for all TV units. Personally I believe 1080p is very accessible and the quality is good enough.
