This doesn't mean that 4k is inherently worse for watching 1080p content since most TVs don't have this problem, but it's important to make sure the model you're buying doesn't have any issue with this before going through with the purchase. There are some 4k TVs that have trouble upscaling 1080p, but it's rare. There isn’t any more detail in the upscaled picture than you can see in the native 1080p picture, so whether or not it looks better is entirely subjective. Overall, the two images look very similar. Above you can see the difference between a 1080p resolution on the 4k Hisense and on the 1080p TCL. However, it doesn't increase the detail of the image since the signal has the same amount of information. This process increases the pixel count of a lower-resolution image, allowing a picture meant for a screen with fewer pixels to fit a screen with many more. Native 4k content is very popular, especially on streaming apps, but some of what you watch may still be lower-resolution content upscaled to UHD, which will look different from native 4k. To present lower-resolution material on a 4k TV, the TV has to perform a process called upscaling. If you have limited space and need a small TV, you'll likely need to get a 1080p model, since 4k TVs are usually available in larger sizes. It's becoming harder to find 1080p TVs in the 2020s, and they're usually limited to small, entry-level models. The original Xbox One and PS4 were limited to 1080p, and then the PS4 Pro and Xbox One X/S, followed by the PS5 and Xbox Series X, were each released with 4k support. Regular Blu-ray discs are 1080p, and there are now 4k Ultra HD Blu-ray discs as well, but it's an entirely new format and requires you to upgrade your Blu-ray player and purchase new 4k Ultra HD Blu-ray discs. Physical video sources, like Blu-ray players and gaming consoles, are starting to support a 4k resolution as well, but they were limited to 1080p for a long time. ResolutionĪs 4k TVs are the norm, native 4k content is also easy to find on most streaming apps like Netflix, Disney+, and Amazon Prime Video. You can see some of the differences between 4k and 1080p below. A higher resolution simply means it supports more content and delivers crispier images. There are different marketing names for each, but having a 4k TV doesn't necessarily mean it's better than a 1080p there are many different factors that affect the picture quality. However, this means that overall, a 4k TV also has four times the total amount of pixels as a 1080p TV, which you can see in the table below. So while the name makes it sound like a 4k display has four times the amount of vertical pixels, in actuality, the amount of vertical and horizontal pixels on a 4k display are each double that of a 1080p display. It can get confusing because 1080p refers to the number of vertical pixels (1080), but 4k refers to the number of horizontal pixels (3840). A 1080p TV has 1920 horizontal pixels and 1080 vertical pixels, while a 4k TV has 3840 horizontal pixels and 2160 vertical. 4k and 1080p refer to the resolution of the display.
