There is a lot of hype about 4K Ultra HD TVs. These sets deliver higher resolution images, but there is more to take into consideration that determines what you can actually see on the screen. Three main factors affect the ability to see the difference between HD and Ultra HD: Screen Size, Seating Distance, and Content.
Screen Size
Although many 4K Ultra HD TVs come in 65-inch and below screen sizes, it may be difficult for many consumers to perceive a significant difference between 1080p HD and 4K Ultra HD at those sizes. However, in screen sizes larger than 65 inches, the difference begins to become noticeable. The larger the screen size is, the more noticeable the difference becomes. If you have the room and the budget, consider a 4K Ultra HD TV with a screen size 65-inches or larger.
Seating Distance
Along with screen size, the closer you sit to the TV also makes a difference. For example, if you shelled out money for a 55 or 65-inch 4K Ultra HD TV, you can sit closer to the screen than you may have with a previous HDTV of the same screen size and still get a satisfying viewing experience, as the pixels (the dots that make up the screen) are much smaller. This means that the distance at which a 4K Ultra HD TV’s pixel structure becomes visible requires a much closer seating distance than you would find with a 720p or 1080p HDTV.
Content
Even if you have a 4K Ultra HD TV, you may not be able to fully take advantage of its higher resolution display capabilities. Just because you have one of these cutting-edge sets, doesn’t mean that everything you see on the screen is 4K.
As of 2021, there are a growing number 4K Ultra HD TV broadcasts. Make sure your cable, satellite, or streaming service provider supports 4K. Make sure your streaming device or cable box is 4K ready. 4K via satellite is available from both Direct TV and Dish Network. The 4K Ultra HD Blu-ray Disc format is available, with both players and movies available in disc format. However, that requires the purchase of a new player and discs, but the upside is that those new players can still play your old DVDs and Blu-ray Discs.
4K Upscaling
4K Ultra HD bodes well for the future as content and compatible devices continue to roll out. However, where does that leave many 4K Ultra HD TV owners if they can’t take advantage of the 4K content that is available? The answer is Upscaling.
All 4K Ultra HD TVs currently available can upscale standard and HD resolution content to match as closely as possible to 4K.Many Blu-ray Disc players and Home Theater receivers also incorporate 4K upscaling. Ultra HD Blu-ray Disc players can also upscale DVDs and Blu-ray discs to better match the display capabilities of Ultra HD TVs.Although not as accurate as true 4K, depending on the quality of the content, results via upscaling can look better than what you see on a 1080p TV (taking the screen size and seating distance factors noted previously).However, VHS, standard resolution broadcast, cable, or satellite, and standard DVD won’t look that great on a large screen 4K Ultra HD TV, but a good HD broadcast, cable, satellite, or Blu-ray disc can look great.
The Bottom Line
4K is here to stay (However, 8K is on the way!). If you haven’t shopped for a TV in a while, you will notice that the majority of TVs on store shelves are 4K models. Most of these sets are also Smart TVs and many provide advanced features, such as HDR, which takes advantage of special brightness encoding on Ultra HD Blu-ray Discs and select streaming content.
