Alex Dos Diaz / Lifewire This information applies to televisions from a variety of manufacturers including, but not limited to, those made by LG, Samsung, Panasonic, Sony, and Vizio. Why 4K? What makes 4K resolution significant is that with the use of ever-larger TV screen sizes as well as video projectors, it provides much more detailed and less pixel visible images than 1080p. 1080p looks great up to about 65-inches, and can still look good in larger screen sizes, but 4K can deliver an even better-looking image as screen sizes continue to increase. The resolution remains constant regardless of screen size. However, as the screen gets larger, what does change is the number of pixels per inch. This means that pixels need to be increased in size, and, or spaced farther apart in order to maintain the same number of pixels on the screen. OPPO Digital How 4K Is Implemented There are plenty of 4K Ultra HD TVs available, as well as a growing number of 4K and 4K-enhanced video projectors. For added support in home theater setups, most AV home theater receivers have either 4K pass-through and/or 4K video upscaling capability.
Video resolution 4k
4K content is available from several streaming sources, such as Netflix, Vudu, and Amazon, as well as via the Ultra HD Blu-ray Disc format and players. Although there are many Blu-ray disc players that upscale standard 1080p Blu-ray disc to 4K, only an Ultra HD Blu-ray Disc player can play discs that contain a real 4K resolution. On the satellite part of the equation, DirecTV and Dish are able to deliver a limited selection of pre-recorded and live 4K content via satellite to its subscribers (provided they have both a compatible satellite box, compatible TV, and subscribe to the appropriate plan). For those that prefer accessing content via cable, your choices are definitely limited. So far, Comcast provides a limited amount of 4K live and on-demand programming, plus access to 4K Netflix. If you have a 4K Ultra HD TV, check with your local cable provider to see if they offer any compatible 4K service. Over-the-air TV broadcasting is where 4K implementation is lagging. Although South Korea and Japan have taken the lead with regular 4K TV broadcasts, it is finishing field-testing in the U. S. to iron out issues such as compatibility with the current broadcast system and added infrastructure costs that stations will incur.
Color, Contrast, and More Of course, all the above being said, you are the one that needs to be satisfied with what you are seeing on your TV screen—increased resolution is one part, but other factors such as video processing/upscaling, color consistency, black level response, contrast, screen size, and how the TV physically looks in your room all need to be taken into consideration.
