Xiaomi Mi 9T: how many inches of screen and detailed view of the matrix

The question of how many inches the screen of the Xiaomi Mi 9T smartphone is one of the most frequent when looking for the technical characteristics of this device. This is not accidental, because it was the display that became one of the key features of the model, which launched in 2019 and won the status of a national flagship.

Many confuse the specifications of different versions, so it is important to immediately clarify: the display diagonal is 6.39 inches, which is the standard for comfortable use with one hand while maintaining multimedia capabilities. However, a dry number is not enough to understand the real quality of the picture, which offers Redmi. K20 (This model is known in the Chinese market).

In this article, we will take a closer look at the physical settings of the screen, the type of matrix used, the pixel density and the impact of these characteristics on everyday use, and learn why this display still looks relevant and how to adjust it correctly for maximum comfort of your eyes.

Exact diagonal and physical display parameters

When we talk about how many inches the screen Xiaomi Mi 9T, we are talking about a diagonal of 6.39 inches, which is the “golden mean” in the world of modern smartphones, allowing the device to remain quite compact, but still provide an impressive area for content. Physical dimensions of the active screen area is approximately 141.3 mm in height and 62.6 mm in width, which gives an aspect ratio of 19.5:9.

It's important to understand that the diagonal is measured from angle to angle of the visible area, excluding the bezels. In the case of the Mi 9T, the frames are minimal thanks to pop-up camera technology, which increases the useful surface area of the front panel to 89.8%. This means that with the same body dimensions, you get more useful space than in the bangs or droplet models.

It's also worth noting the pixel density, which directly affects the clarity of the image. 2340×1080 points, the density is 403 ppi (pixels per inch). In comparison, this is higher than many budget models, and ensures that there is no visible graininess even when you look at the screen up close. AMOLED In combination with such density gives a deep black color and high contrast.

⚠️ Note: Do not confuse the diagonal in inches with the physical dimensions of the body in centimeters. A diagonal of 6.39" does not mean that the phone is huge, since modern frames allow you to minimize the overall dimensions.

Type of AMOLED matrix and color rendering quality

How many inches of screen does Xiaomi Mi have? 9T, You can't ignore the type of panel you're using. AMOLED, It's a product made by Samsung, and it's a key determinant of visual perception. IPS-screen, AMOLED No additional lighting is required, as each pixel glows on its own.

The benefits of this technology are obvious when viewing content at night. The black on the Xiaomi Mi 9T screen is completely black, as the corresponding pixels are simply turned off. This not only improves contrast, but also saves battery power when using dark themes. The color coverage covers 100% of the DCI-P3 space, making the picture rich and bright.

Users often argue about which color reproduction mode to choose. By default, MIUI activates the "Vivid" mode, which artificially saturates the colors, making them more flashy. For professional work with photos or just for natural shades, it is better to switch to "Standard" or "Saturated" mode in the screen settings.

• 🎨 Deep black: Perfect contrast thanks to pixels shutdown.
• 🌈 Color coverage: Support for a wide range DCI-P3 photo-realistic.
• 👁️ Protection of vision: No flickering (PWM) At high levels of brightness reduces fatigue.
• 📉 Savings: Dark theme really prolongs the work time autonomously.

Full HD+ resolution and pixel density

Screen resolution Xiaomi Mi 9T form 2340×1080 It's the standard for Full Pixels. HD+, diagonally 6.39 The inch provides excellent font clarity and image detail. Many users wonder if this is not enough in the era. 2K and 4K Practice shows that the human eye from the distance of the outstretched arm (about the distance of the human eye). 30 (c) sees little difference between FHD+ and QHD screen-to-screen 6.5 inch.

Moreover, using Full HD+ resolution has a positive effect on the performance of the Adreno GPU (depending on the version of the Snapdragon 730 or 855). Less pixels require less processing power to render the interface and games, which contributes to a more stable FPS and less heat of the device, which is especially important for mobile gaming fans.

If you are used to lower resolution screens (HD+), The difference is enormous. The text becomes clear, the ladders on the boundaries of the letters disappear. QHD-On the screen, you may not notice a significant difference in everyday use, but you will notice an increase in the speed of the interface.

Update frequency and sensory response

One characteristic that is often overlooked when discussing how many inches the screen the Xiaomi Mi 9T has is the refresh rate.The screen runs at a standard 60Hz. This means the image is updated 60 times per second. For 2019, this was the absolute standard, however, current models often offer 90Hz or 120Hz.

Despite 60Hz, thanks to the optimization of the MIUI shell and a powerful processor, scrolling the tape on social networks and menus looks smooth. However, compared to modern "site" the difference can be noticeable. But the touch sampling rate of the Mi 9T is set up perfectly. The screen instantly responds to touch, which is critical in shooters and dynamic games.

Not only is it a hertz, but it's also a multi-touch screen that supports up to 10 simultaneous touches, which allows you to play complex projects that require multiple fingers at once, and ensures that you don't have phantom taps or input delays.

Screen settings and hidden MIUI functions

After buying the Xiaomi Mi 9T, it is recommended to conduct a competent display setting. The system offers many tools for calibration. Go to Settings → Screen to access the basic parameters. Here you can change the color scheme, font size and image scale.

One of the useful features is Read Mode, which adds a warm yellowish filter that mimics paper, which reduces eye strain when reading long-term text, and you can set the schedule for turning on this mode or activate it by brightness, and you can also have Safe Mode, which limits maximum brightness to protect children's vision.

For advanced users, an engineering mode is available to calibrate the touch layer. To do this, dial the code ##6484## in the Phone app. From the testing menu, select Touchpanel. Here you can check the uniformity of the response across the entire screen area and make sure there are no dead zones.

⚠️ Warning: Do not use aggressive chemicals to clean the screen. Alcohol or acetone can damage the oleophobic coating, making the finger slip worse, and the display will remain more greasy traces.

Comparison with competitors and final conclusions

In its price segment at the time of the release, the Xiaomi Mi 9T offered a screen that outperformed many of the competitors who used IPS-matrixes with the worst viewing angles. Even after a while, the picture quality remains high. The main competition was with models from Realme and Honor, but the lack of a cutout for the “nine” gave it the advantage of ivility.

Compared to the newer models, the Mi 9T loses in refresh rate (60 Hz vs. 90/120 Hz) and maximum brightness at peak (not easy to read in direct sun). However, for watching videos and games indoors, its characteristics are more than enough. The main advantage is a one-piece glass panel without islets.

💡

To extend life AMOLED-Try not to keep a static image at maximum brightness for long hours. Use live wallpaper or change the content on the screen often to avoid pixel burnout.

To sum up, the Xiaomi Mi 9T screen is the benchmark of the mid-range of the late 2010s, combining great color reproduction, high resolution and ergonomic size. For a user who is not a professional designer or hardcore gamer requiring 120Hz, this display will remain pleasant and comfortable for a long time to come.

💡

The Xiaomi Mi 9T screen with a diagonal of 6.39 inches and an AMOLED matrix remains one of the best in its class due to the lack of cutouts and excellent color reproduction, despite the standard frequency of 60 Hz.
