Is a 120 Hz monitor really necessary?

# ** Is a 120 Hz screen really necessary? ** **Screen frequency or screen refresh rate are all equipped by mobile manufacturers for their flagship smartphones, is this the criterion to select phone.** About 3 years ago, phone screen scanning frequency was hardly interested by many users. However, this feature is gradually being paid attention by mobile companies to advertise on high-end products. Samsung or Apple flagships are equipped with 120 Hz refresh rate, gaming phones even have screens up to 240 Hz. So what is the benefit of the refresh rate and should users choose a phone with a refresh rate? ## What is the refresh rate The information the user sees on the phone screen is not actually an animated image, but a sequence of still frames projected at a very fast speed, creating the impression that they are moving really. Scan frequency can simply be understood as a measure of the number of times the image on the screen changes (the number of displayed frames) per second and is measured in Hertz (Hz). Monitors with 60 Hz refresh rate display 60 fps. Similarly, 120 Hz and 240 Hz monitors will display at 120 fps and 240 fps respectively. Therefore, a higher refresh rate means less motion blur and significantly clearer picture quality, resulting in a smoother viewing experience and less eye strain from prolonged viewing. on the screen. 3-4 years ago, most smartphones were equipped with 60 Hz screens. However, in 2023, mid-range smartphones with 90 Hz refresh rate are becoming popular. High-end flagships usually have 120 Hz panels. Some products may also have screens up to 144 Hz, 165 Hz or 240 Hz. Specifically, the iPhone 14 Pro supports screen speeds up to 120 Hz. While gaming phones like Asus ROG 6 Pro have a refresh rate of up to 165 Hz. In some cases, users can set the frame rate manually in the settings if they want to keep the frame rate lower than the maximum to prolong battery life or avoid resolution drops. ## Pros and cons of high refresh rate The biggest strength of a high refresh rate monitor is smooth motion on the screen. Although operations like surfing the web or Facebook don’t make a big enough difference for the average user to notice, apps and content with a lot of motion like games will be much smoother with a screen with a refresh rate. High. This will be very noticeable when the user puts two devices with 60 Hz and 120 Hz refresh rates next to each other. However, a screen with a high refresh rate consumes a large amount of processing power and therefore consumes much more battery, which is especially important for users who are traveling or do not have a place to charge their phone. . In the test of YouTuber Darius K, the Xiaomi BlackShark S4 consumes 23% of the battery within 1 hour of playing the game at 120 Hz, while 90 Hz is only 18%. In addition, some phone companies choose to reduce the screen resolution to balance the energy consumption for a high refresh rate, making the image no longer beautiful and sharp. Furthermore, most apps currently don’t support refresh rates beyond 120 Hz, meaning the experience won’t be smoother on a 240 Hz screen than on a 120 Hz screen. So, if users often use smartphones to play games and want a fast, smooth experience, without jerks, lags, and frames, a smartphone that supports 120 Hz screen will be a worthy choice. remind. As for general users, not too concerned about smooth surfing experience, and prioritizing battery life, mid-range smartphones with 60-90 Hz screens will be more suitable for daily use.
