We have reviewed the standard model and our test of Xiaomi 12 Pro, one of the tops of the reference range of this generation, will also be released shortly. Not only the size changes between the two models but also the quality of the screen implemented. If on Xiaomi 12 we find a traditionally made OLED panel, on the Pro model there is a more advanced LTPO 2.0 panel.
As explained in the dedicated focus, this acronym hides a technology that makes screens less energy-intensive. In addition, a new software update has just been released that refines the screen capabilities of the Xiaomi flagship.
The first novelty of the MIUI update improves precisely the capacity of the variable refresh rate intrinsic in the LTPO 2.0 technology of Xiaomi 12 Pro. Unlike Xiaomi 12, whose refresh rate can go down to only 60 Hz, the Pro model has a range of variability that goes from a minimum of 1 Hz to a maximum of 120 Hz. This feature is of a hardware nature, but it needs the software to assist it and make it work at its best.
Imagine you are scrolling through a menu: as soon as you touch the screen, the display will rise to 120 Hz and the scrolling will continue by inertia and then stop. During this movement, the screen will drop from the peak of 120 Hz down to a minimum of 10 Hz. With this update, Xiaomi has increased the refresh rate adjustment steps, as you can see in the image above.
To do this, the Xiaomi software dynamically intervenes in the Android ScrollView and ListView parameters that manage the screen refresh rate. In this way, Xiaomi avoids the stuttering that could result from poor FPS management.
Let’s move on to another novelty deriving from the latest update for Xiaomi 12 Pro. Like many other models, the top of the Xiaomi range is equipped with a sight protection function, which is the classic anti-blue filter. What Xiaomi has done is to modify it to make it more effective: instead of affixing a simple yellow patina to the display, it adjusts the various colors in a different and independent way. The goal is to reduce blue lights more precisely while avoiding too much color accuracy.
If you look at the CIE 1931 RGB color space, blue lights predominate in the space you see circled in the image above. Consequently, the intervention of the eye protection mode will be more incisive in this space, affecting less the chromatic spectra where the amount of blue is less.
To understand, here is a demonstration of how this feature works. In the image above, at the top left there is the original image, at the bottom there is how it looks with a standard safeguard mode and on the right as it appears with the new Xiaomi mode. It can be seen how colors such as red and green, not full of blue lights, remain almost undermined, unlike the white background.
