In recent months there has been much talk about the amount of refreshment on a portable screen, that if 90 hertz, 120 hertz, if the mean response is 180 hertz. Why is there so much history with Hertz? Why should I care?
We do a thorough review of everything you need to know about this technology, where it comes from, what it works for, what not to use and phones with the best screens when it comes to refresh rates.
Introduction: what is hertz or Hz
It is a measure of the international metric system. Its name comes from Hertz, a German naturalist who lived between 1857-1894. This is the sum made to measure cycles per second, a very important measure in wave physics, and the electronic world.
Heinrich Rudolf Hertz, a German physicist who discovered the result, eventually called Hertz.
Hertz is a frequency metric and for each electronic component it has a frequency series. This may be one of the most important in the world of technology:
- Hertz in processor: At the ordering level, the processor is packed with millions of nanometric-level transistors. These oscillate transistors are binary values (0/1) in GHz sequence. For example, a processor with a high speed of 2.8 GHz means that its transistors have the power to change state frequencies 2,800,000,000 per second. This makes the speed in hertz constant performance measure.
- It is important to consider from these processors that buildings of this also has a huge impact on performance, and the fact that a lower hertz processor can be much faster by having a faster structure.
- Hertz telecommunications: wireless communication uses hertz as a standard. Now, it is used to generate electrical waves. These waves transmit information by oscillating and allow your devices to communicate over the phone. Each wave has a frequency characterized and a wavelength.
- The simplest example is WiFi, and it's very possible to have two networks on your router, one 2.4 GHz and one 5 GHz. Here you can easily see the difference between frequency and wavelength, Starting with 5 GHz WiFi you will see that it is fast but you will also lose coverage by moving it a bit further, while 2.4 GHz waves provide better coverage to swap lower speeds.
- Hertz on the screen: This is a fashion discussion, and the fact that within a few months of a few models have come up with amazing renewal rates. Higher refresh rate, better response flexibility and critical response.
The mobile screen has two refresh rates
The degree of refreshment on the screen is directly related to the frames per second. If the screen is 60 hertz, it means that each pixel can change color 60 times in one second, if it is 90 it can change 90 times per second, and if it is 120, it can change the color up to 120 times.
What we see on the screen, whether it's a wallpaper, an internet page, a video or a game, is gone there is a continuous sequence of structures. The feeling of numbness is marked by the number of times the screen is able to change its shape. This feature is important when measuring motion, as you'll see that animations are not very smooth.
Generally, the best test to quickly detect the importance of clicks from your browser is a UFO Test. It is a test that shows similar UFO movements at different levels of refreshment, being able to see the difference between being too high on your screen and low prices.
UFO Examination.
On the other hand, screens and they have a degree of refreshment to the touch, a measure that although we can't see, has a positive impact on user experience. This update level doesn't work to indicate anything, but it refers to the number of times the touch pad looks where we're touching. This level is more important for the speed of critical reactions, in addition to contributing to better detection.
Not all content is equally beneficial to resale prices
If you are considering getting a new cell phone and are starting to read everywhere about these refreshments, you may be wondering, do I really need them? Will I actually recognize and enjoy it? Usually yes, but there are a few situations to consider:
- The program interface will feel simple: This idea will be when you open an application, open a notification bar or simply browse the website or social network.
- Message requests: Not much compatibility as messages are usually organized content.
- Photos: a harmonious consistency, because usually the viewer of the photo app goes to less than 30 frames per second and you won't see a change.
- Video recording: a harmonious consistency, since most cameras record at most 60 pictures per second.
- Games: The game should be configured to release more than 60 images per second, and if so, it is one of the most appreciated.
- Here it is important that not only the game is optimized and has a screen, but also that the mobile phone has enough power.
- Multimedia content: In the same way videos are recorded at 30 or 60 images per second and movies at 24/48 images per second, the high quality of the frame does not provide any improvement when viewing the videos.
Excellent mobile screen: all models come with high refresh rates
- 144 Hz:
- 120 Hz:
- 90 Hz:
- 60 Hz:
- All cell phones in the market.
