How to improve the picture quality on Xiaomi phone: a complete guide to setup

Xiaomi’s modern smartphones are equipped with great displays, but often out of the box the image does not look as the owner would like. Standard color settings can seem too cold or, conversely, too pale. This is due to the fact that manufacturers often calibrate screens to average standards, forgetting about the preferences of the individual user.

Fortunately, MIUI and its successor HyperOS provide a wide range of tools to fine-tune the visual interface. You can change the color gamut, increase font resolution, activate additional visual protection features, or, conversely, squeeze out maximum brightness. In this article, we will discuss all the available ways to make the picture on your device perfect.

Before you make any changes, you have to understand that screen calibration is a personal process, that what is ideal for one person may not be acceptable for another. So experiment with settings gradually, evaluating the results in different light conditions, and we will look at both standard methods available to everyone, and more advanced techniques for advanced users.

Basic screen settings in MIUI and HyperOS

The first step to improving image quality should always be to learn the standard display settings. This is where the basic controls of color reproduction are located. Go to the Settings menu. → Screen to see the basic settings. Here you'll find the dark theme switch, brightness settings and refresh rate.

The default system often chooses the "Saturated" or "Vivid" mode, which makes the colors more vivid and contrasting, but not always realistic. If your goal is maximum color accuracy close to sRGB standards, choose the "Standard" mode.

⚠️ Warning: The "saturated" mode consumes battery power faster AMOLED-screens due to the higher peak brightness of individual subpixels, so it is better to use a standard profile to save energy.

You can also use color temperature settings in this section, where you can move the white balance to warm yellows or cold blues, and warm colors are less tiring in the evening, while cold colors give you a sense of clarity in daylight.

Use of advanced settings and DPI

For those who don’t have standard sliders, Xiaomi offers access to advanced settings through the developer menu. Changing the density of DPI (Dots Per Inch) allows you to make interface elements and fonts clearer or, conversely, larger without changing the physical resolution of the matrix.

To get into this menu, you need to click on the build number in the About Phone section several times until you notice that you have become a developer. Then, in the advanced settings, find the Minimum Width (or Smallest Width). The standard value is usually about 360-411 dp.

• 🔍 Increased importance DPI Makes interface elements smaller, allowing you to fit more information on the screen.
• 📏 Reduce the value DPI Enlarges icons and text, which is useful for users with impaired vision.
• ⚙️ Changing this parameter does not affect the physical resolution, but changes the logical resolution of the system.

Be careful when changing these values. Too high can make text unreadable, too low can cause some interface elements to stop fitting on the screen, and the optimal is to change the step by no more than 20-30 units from the factory value.

💡

Write down the original DPI before changing, so that if necessary, quickly return everything as it was. Standard values are often multiples of 10 or 12.

Set up fonts and scale

The quality of the image perception is directly dependent on the readability of the text. MIUI has a separate section for tweaking fonts, which is often ignored. Go to Settings → Screen → Text Size and Font, and you can not only resize it, but also choose the style of the font, which significantly affects the overall aesthetic of the interface.

Using a system font with good readability, such as Roboto or specialized fonts from the MIUI Themes theme, can significantly improve visual perception. Some custom fonts have improved kernigov (letter spacing), making the text more airy and easy to see.

And don't forget to zoom in. If you've got a high resolution screen, but the fonts are small, your eyes will get tired faster, and the balance between the amount of information on the screen and the comfort of reading is a key factor in quality picture.

Vision protection function and reading modes

Modern OLED and AMOLED arrays used in Xiaomi phones can cause eye fatigue due to low brightness (PWM) or excess blue spectrum. To combat this, the system has special modes.

New firmware versions have a paper mode that not only changes the color of the background, but also adds texture that mimics electronic ink, and it's one of the most effective ways to improve long-term reading by turning a bright screen into an e-book.

⚠️ Note: Paper Text mode can reduce color reproduction in games and videos, so it is recommended to include it only for reading or working with documents through an automatic schedule.

Also worth mentioning is DC Dimming, which is available in some models through a hidden menu or in the usual screen settings, and it removes the flickering of the screen at low brightness, which is critical for people with senses.

You can find it by including the option "Remove the restrictions on the use of functions" in the developer menu.

Engineering menu and color calibration

For advanced users who want to get the perfect picture, there is an access to the engineering menu, which is a powerful tool to adjust the display parameters at the hardware level. Be very careful: the wrong settings here can distort the colors beyond recognition.

To enter the engineering menu, open the Phone app and dial ##64663## (or #3646633## for some MediaTek models). In the Single Item Test menu that opens, select the section associated with the display (often called LCM or Display) where you can find the gamma and color balance settings.

• 🎨 Gamma adjustment – allows you to adjust brightness in shadows, medium tones and lights separately.
• 🌡️ Color Temperature – Accurate white temperature setting in Kelvins.
• 🔧 Panel parameters – reset or calibrate panel parameters (experts only!).

This method is justified if standard means cannot remove the obvious greenish or pink hue that is characteristic of some batches of screens, but for most users, software calibration through the theme settings is enough.

💡

The engineering menu is the final frontier of the setup. If the screen has a clear defect (spots, stripes), software calibration will not help, you need to replace the module.

Third-party applications and widgets

If built-in tools are not enough, Google Play apps come to the rescue, and programs like Screen Balance or Blue Light Filter allow you to flexibly configure color channels (RGBs) by creating your own profiles for different tasks, and they can overlap the image on top of the system, adjusting colors in real time.

However, it is worth remembering that third-party filters can consume power and reduce device performance, especially on weak processors, and they can conflict with the system dark theme MIUI, causing color inversion in some applications.

Another option is to use theme widgets. The MIUI theme store has components that change icons and wallpapers optimized for AMOLED (True Black), using a completely black background on such screens not only saves battery, but also visually improves the contrast of the image, making the colors deeper.

So to sum up, your Xiaomi is capable of producing studio-quality images if you set it up properly. Start with the simple steps of choosing the right profile and adjusting the brightness. If that's not enough, experiment with DPI and fonts. Only in the extreme, use an engineering menu. If you set it up properly, you'll unlock 100% of your matrix's potential.

💡

Rub the screen with microfiber regularly. Fat marks and dust create the illusion of a dull screen and reduce contrast, negating all software settings.
