Which 4K TV Should You Buy?ĤK TVs have been hitting the market for a few years now, and have finally become both affordable and functional. Some budget TVs can decode HDR content and display it, but their panels don't get dark enough, bright enough, or colorful enough to make much of a difference over standard dynamic range content.

To watch HDR content you need a TV that supports HDR, ideally with a panel that can faithfully display the full range that HDR requires. Not all 4K content is HDR, but when it is, and your TV can handle it, it looks much better because of that wider reach of light and color. Think of it this way: 4K determines the number of pixels in your video, while HDR determines how much light and color each pixel can display.
HDR content stores wider and more granular values of brightness, darkness, and color levels than standard dynamic range content, which lets TVs that support HDR show pictures that are brighter, darker, and more colorful. HDR is a type of content, most often in 4K, that expands the range of color and light that can be shown. They aren't, and our guide to HDR explains the differences in more detail. High dynamic range (HDR) is a confusing term, and it's easy to mix it up with 4K or assume that they're the same thing. If you spend the extra money on an 8K TV, you'll be relying entirely on the TV's upconversion process of 4K or lower resolution media, and that can't be as good as native 8K content. There are no standardized 8K streaming formats or physical media, though. We go into detail about what 8K means and when you can expect it in our 8K explainer, but for now all you need to know is that some TVs are hitting 8K resolution (7,680 by 4,320, four times the resolution of 4K), but there is no consumer content available in native 8K and there won't be any for a while. The long answer is that 8K is already here for some high-end TVs, but it isn't going to be a major factor for some time. This is a major factor for large TVs as well, especially since 65-inch models are as affordable as 55-inch TVs were just a few years ago, and even 75-inch TVs can be found for reasonable prices (with some models pushing past 80 inches, but at that point the the prices jump much higher). 4K is another big jump in terms of clarity and detail, especially as people are becoming more and more used to the incredibly tiny pixels displayed by the high-resolution screens on their phones.

While regular viewers struggled to see the difference between 1080p and 720p on smaller televisions, it's much more obvious on 40-inch and larger TVs. You can also stream 4K video over the internet, which similarly requires a fast connection Netflix recommends a steady 25Mbps downstream speed to watch 4K content over its service. This was initially a concern as HDMI 2.0 was becoming more commonplace, but right now you can count on nearly any home entertainment device you buy to support HDMI 2.0, and based on our tests you'd have to really go junk shopping to find an HDMI cable that can't transmit a 4K60 HDR picture. The HDMI 2.0 standard was developed to support 4K, and allows 2160p video to be displayed at 60 frames per second.
