If you just want to watch movies and TV shows, 120Hz is really not necessary. In case you're sensitive to 24p judder, make sure that the TV has a feature that can fix it.
The higher the refresh rate, the better the picture quality. 4K 120Hz TV offers a refresh rate of 120Hz to let you enjoy a cinematic-like experience in home comfort. As a result, the high refresh rate keeps the images still by reducing the motion blur so you can have sharp, clear, and top-notch picture quality.
Refresh rates matter most while watching action movies, sports, and fast-paced gaming. For most users, a TV, projector, or monitor that can produce 60Hz or 120Hz refresh rate is more than enough, but for anyone who watches a lot of action or is a gamer, 120Hz is the minimum you should choose.
For video streaming you shouldn't notice any difference.. Just use the native refresh rate for your TV. For broadcast TV, you rarely need more than 60 Hz. Where refresh really makes a difference is in gaming, where it affects latency.
The higher the number, the smoother the screen will appear to the human eye. This means that a 120Hz display – which updates itself 120 times a second – will look noticeable slicker and more natural than your average 60Hz screen which only updates itself 60 times a second.
If you just want to watch movies and TV shows, 120Hz is really not necessary. In case you're sensitive to 24p judder, make sure that the TV has a feature that can fix it.
In theory, a higher refresh rate should equal a better quality picture because it cuts down on blurriness. A 120Hz display decreases the appearance of "film judder" or blurring that might be noticeable to some on a 60Hz screen. Improvements beyond a 120Hz refresh rate are unnoticeable.
This makes the images appear jumpy or flicker. Humans can easily tell the difference between 60hz and 120hz/144hz monitors. We need higher refresh rates to have smooth moving objects on screen.
To watch Netflix in Ultra HD, you need:
A 60Hz TV or computer monitor compatible with Ultra HD streaming from Netflix. A steady internet connection speed of 15 megabits per second or higher. Streaming quality set to Auto or High.
As for display, Netflix requires a minimal 60Hz refresh rate to depict 4K content. If you select a 4K multimedia monitor or other display for some reason run at 30Hz, the result would be no 4K for you. That shouldn't be much of a concern as nearly all displays these days put out 60 frames per second or more.
With a 60Hz refresh rate, you'll enjoy a much smoother and more fluid experience, with less motion blur and clearer details. By contrast, 4K 30Hz can result in a choppy and disjointed experience, especially in fast-paced games.
Higher refresh rates mean that a TV or monitor can display more frames per second (fps) which, depending on the content it's fed, could affect how smooth and pleasing your video looks.
If you prioritize smoother motion, then 1080p on a 120Hz monitor will be better for you. This is because a higher refresh rate allows for smoother and more fluid movement, which can be particularly beneficial for fast-paced gaming or action scenes in movies.
So, keeping things as simple as possible, for a display to be able to receive a 4K 120Hz feed from a console it must have at least one HDMI capable of handling data rates of 32.08Gbps or more.
There is a 50Hz or 60Hz refresh rate for displays. PAL displays (the standard we use in Australia) operate at 50 Hz; NTSC displays (the standard used in North America) operate at 60 Hz.
The HDMI 2.1 specification can handle 4K and 8K video at up to 120 frames per second with room to spare. If you aren't planning to get an 8K TV just yet, the 2.1 standard is mostly important for high-end gaming, due to the potential of 4K signals at frame rates higher than 60fps coming from gaming PCs and consoles.
Every modern TV has a refresh rate of either 60Hz or 120Hz. While 60Hz TVs are good enough for watching almost any videos without any problem, 120Hz TVs are usually better for watching movies and playing video games.
Multipurpose Chart, HDR10: 3840x2160: 29.97 fps.
Subscribers with the Standard plan can watch content in a 1080p resolution, which means HD and Full HD. Premium subscribers get it all; the only limitations imposed on the top resolution levels come from the content itself. With the Premium plan, you can watch Ultra HD (4K) and HDR content.
The human eye cannot directly see 120 Hz. High contrast fluctuations are not perceived for frequencies much above 60 Hz.
Most experts have a tough time agreeing on an exact number, but the conclusion is that most humans can see at a rate of 30 to 60 frames per second. There are two schools of thought on visual perception. One is absolute that the human eye cannot process visual data any faster than 60 frames per second.
A higher refresh rate means a smoother-looking screen that's easier on the eyes. So, if you're trying to ease your eyestrain, a refresh rate of 120 Hz is optimal.
Some videos and digital films are shot at 60fps, which when played at normal speed creates hyper-real-looking footage. 120fps, 240fps, and higher frame rates are used for recording video to be played back in slow motion. 60fps, 120fps, and 240fps are all high frame rates used for slo-mo.
Basically, the 60Hz display on the iPhone 14 feels smoother than the 60Hz panels of most Android smartphones. However, if you compare the iPhone 14's display with the Pro variants or with other smartphones rocking a 120Hz panel, there's going to be a noticeable difference.
