8K is 7,680 by 4,320 resolution, or four times the number of pixels of 4K. You might have heard about it, and the new HDMI 2.1 standard is designed to support it. Since it's a physical media format, you don't need to worry about your internet connection to be sure you're getting 4K, either. The good news is that it stores 4K video with HDR (explained below), and even can handle advanced surround sound audio if your speaker system supports it. Don't expect to play them on your current Blu-ray player, though you need a dedicated Ultra HD Blu-ray player, a Microsoft Xbox Series X, or a Sony PlayStation 5 to handle the format. Ultra HD Blu-ray discs are a relatively new physical media format similar to Blu-ray discs.

New films are also coming out digitally in 4K through various on-demand streaming services like Vudu. If you have a very fast internet connection, you can watch some excellent shows on Amazon and Netflix in 4K (and most new original programming on the services is being produced at that resolution). In fact, every TV on this list is 4K.ĤK content is now freely available on many streaming services and on Ultra HD Blu-ray discs, even if it hasn't been adopted by broadcast or cable TV services yet.

Realistically, you'd be hard-pressed to find a TV from a major brand larger than 40 inches that isn't 4K. The higher resolution no longer commands a huge premium, and you can now find a 65-inch 4K TV for under $1,000. Now it's no longer a question: 4K has become the standard for medium-sized and larger televisions from every major manufacturer. Then it moved on to 1080p versus Ultra HD, or 4K (3,840 by 2,160, with eight million pixels). The TV resolution question used to be between the options of 720p (1,280 by 720 resolution, or just under one million pixels) and 1080p (1,920 by 1,080, or just over two million pixels). But which one should you buy? Here are the main points to consider when shopping for a new set, as well as the best TVs we've tested. New types of screens with organic light-emitting diode (OLED) panels and ultra-high definition ( UHD, or 4K) is replacing the 1080p standard we've become used to. The TV market has been changing a lot recently, both in terms of technology and price.
