PWM problem in smartphones
Google The Pixel 8 Pro has proven itself to be a reliable smartphone with an impressive screen. However, for people sensitive to pulse width modulation (PWM), using the device may cause discomfort. PWM is a technology used in most modern OLED displays to adjust brightness. For some users, the low PWM frequency may render the screen virtually unusable.
Features of PWM in OLED displays
Pulse width modulation plays a key role in controlling image brightness on OLED screens. It allows our eyes to perceive the display as brighter or dimmer. When the switching frequency is reduced and the brightness is reduced, you can sometimes notice black bands in photographs of OLED screens.
Individual sensitivity to PWM
Most people don't notice the difference between low and ultra high PWM frequency displays. However, for some users, low frequency screens can cause significant eye strain. Unfortunately, Google Pixel devices fall into the category that can create such discomfort.
Modification to increase the PWM frequency
Now, thanks to a new modification, the Pixel 8 Pro is able to significantly increase the PWM frequency. Using a modified boot image, the frequency can be doubled to 480 Hz. However, to do this, you need to gain root access to the device.
Experimenting with extreme frequencies
Further modifications allowed the Pixel 8 Pro to run at 3840 Hz. The smartphone functioned without any obvious problems, but the image acquired a noticeable green tint and other color distortions. It is probably because of these deviations in color reproduction that Google does not use such a high PWM frequency in its devices.
Technology Outlook
As other manufacturers continue to improve their PWM performance, hopefully Google will also follow this trend in the future . In the meantime, enthusiasts can independently modify the operation of current models, taking on the risks associated with changing the basic software of the device.

Wow, I didn’t know that PWM could have such an effect on the comfort of using a smartphone! 😯 I wonder how many people suffer from this?
Hans
Yes, Isabella, this is a really important aspect. I myself encountered the PWM problem on my old phone. My eyes got tired very quickly. Good thing Google is working on this in the Pixel 8 Pro!
Marie
Guys, has anyone tried this modification on Pixel 8 Pro? 🤔 I wonder how noticeable the difference in use is?
Carlos
Marie, I haven’t tried it, but I’m confused by the need to obtain root access. This may affect the warranty and safety of the device, no?
Günter
Ha, again these young people are running around with their smartphones. In my day, people interacted face to face rather than staring at screens. And nothing, my eyes didn’t hurt. All this is your PWM - an invention of marketers.
Sophia
Carlos, you're right about the risks. But for those who suffer from low PWM frequency, this may be the only solution. Although 3840 Hz sounds impressive! 😮
Oleksandr
Günter, technology does not stand still. This problem is real for many. Personally, I'm glad that manufacturers are working on improving screens. Although I agree that no one canceled live communication 😊
Isabella
I wonder if other manufacturers are also working on this problem? 🤔 Maybe someone knows about the successes of Samsung or Apple in this direction?
