Detailed analysis of the screen Xiaomi Redmi Note 8T: characteristics and image quality

Xiaomi Redmi Note Smartphone 8T It has long been one of the most popular mid-range devices, and its display played a key role in this, and many potential buyers still wonder: What kind of screen is it, how good is it, and does it meet current standards? Unlike many of the low-end competitors. TN-The manufacturer decided not to save on the visual experience of the user.

The developers have equipped the device with a modern IPS-matrix, which provides wide viewing angles and excellent color reproduction. This solution was a pleasant surprise for those who are accustomed to seeing in this class of devices faded colors and inversion at the slightest tilt of the phone. In this review, we will discuss all the technical details, including resolution, pixel density and maximum brightness level, so you can get a full impression of the quality of the picture.

The 6.3-inch diagonal is not chosen by chance, as it is the โ€œgolden meanโ€ for controlling one hand. Xiaomi Corporation has applied proven technologies here, adding Gorilla Glass 5 protective glass to improve impact resistance. Below we will take a detailed look at how these characteristics affect everyday use of the gadget.

Type of matrix and production technology

The visual part of the smartphone is based on the IPS (In-Plane Switching) matrix, which is a liquid crystal technology that allows you to achieve stable images regardless of the angle of view. Unlike cheap analogues, you will not see the effect of negative or a sharp drop in contrast when you look at the screen from the side. Colors remain saturated and natural even at a maximum viewing angle of 178 degrees.

The manufacturer used high-quality backlight that is evenly distributed throughout the display area. This minimizes the effect of "lights" at the edges, which is often found in low-end devices with poor build. IPS Redmi Note 8T Provides a color coverage close to the standard NTSC 84%, which makes the picture lively and bright, although not up to the level of flagship AMOLED-screen.

It is important to understand that IPS-The screens consume a little more energy than OLED, But they benefit from longevity and the risk of pixels burning out over time. For users who spend a lot of time reading text or navigating, this is a significant plus. Lack of flickering (PWM) at low brightness levels also protects the eyes with prolonged use.

  • โœ… Technology: IPS LCD s LED-lighting provides stability of colors.
  • โœ… Viewing angles: Virtually no distortion when viewed from an angle.
  • โœ… Durability: The risk of burnout of static interface elements is reduced to zero.
  • โœ… Safety: No low-frequency flickering (PWM) reduces eye fatigue.

โš ๏ธ Attention: Despite the high quality IPS, The absolute black color on this screen will look like a dark gray due to the peculiarities of the backlight, which is the norm for this technology.

Resolution, pixel density and clarity

The display of the smartphone has a resolution of 1080 ร— 2340 pixels at an aspect ratio of 19.5:9. This pixel density (PPI) is approximately 409 dots per inch. For a diagonal of 6.3 inches, this means that the human eye is almost unable to distinguish individual pixels at a normal viewing distance. The picture looks smooth, without โ€œladdersโ€ on fonts and icons.

FullHD+โ€™s high resolution allows you to comfortably view high-quality video content. YouTube, Netflix and other streaming services will display content in native resolution without losing detail, especially when viewing fine text or when working with graphics, where line clarity is important.

Itโ€™s also worth mentioning that the standard aspect ratio makes the smartphone convenient for consuming content created for todayโ€™s large-screen screens.The black bars on top and bottom when watching classic 16:9 videos are minimal, which increases the usable area of the image.

For maximum font clarity, go to the settings and select โ€œLargeโ€ or โ€œGiantโ€ text size if the standard seems small to you, but remember that this will reduce the amount of visible information on the screen.

Color rendering and image calibration

The factory screen calibration in the Xiaomi Redmi Note 8T is in Standard mode with a slight slope into cold shades. This is a popular solution among manufacturers, since the โ€œcoldโ€ picture subjectively seems clearer and brighter for most users. However, a selection of color schemes is available in the display settings, which allows you to adapt the image to your personal preferences.

The user can choose between Saturated Colors, Standard Colors and Warm Colors. The saturated color mode artificially increases saturation, making the picture more "screamy", which may appeal when watching a video, but distorts the real colors of the photos. For professional graphics work, it is better to use standard or warm mode.

The maximum brightness level is about 450 nits. This is enough for comfortable use indoors and in cloudy weather outside. However, in direct sunlight, the readability can decrease, and you have to look for a shadow or cover the screen with your palm. Automatic brightness adjustment works correctly, but sometimes requires manual adjustment through the slider in the notification curtain.

  • ๐ŸŽจ Modes: Three color reproduction profiles available for different tasks.
  • โ˜€๏ธ Brightness: 450 nits maximum is the average for this class.
  • ๐ŸŒ™ Night mode: Blue filter reduces eye strain in the evening.
  • ๐Ÿ“‰ Minimum brightness: Low enough not to blind in the dark.

โš ๏ธ Note: When you turn on the "Energy Saving" mode, the system can forcefully reduce the maximum brightness of the screen, making the image dim even when the slider is twisted.

Protective glass and oleophobic coating

The front panel of the smartphone is protected by Corningโ€™s hardened glass Gorilla Glass 5, which is a generation of glass that focuses primarily on falling, not scratching. According to the manufacturerโ€™s tests, glass can withstand a drop from a height of 1.6 meters to a hard rough surface in 80% of cases, which is a great indicator for a device that often drops.

But Gorilla Glass 5's scratch resistance is medium. The keys in his pocket are probably not scary, but sand or fine dust can leave micro scratches over time. The factory also has an oleophobic coating that repels greasy finger marks and makes it easier to slide when swipes. Over time (after 6-12 months of active use), the layer can erase at the center of the screen.

What to do if the glass breaks?
If only the security glass is broken, and the image and touchscreen work, you can only replace the glass in the service, and if the matrix is damaged, you will need to replace the entire module, which is expensive.

To extend the life of the oleophobic layer, it is recommended to wipe the screen with a soft microfiber, rather than coarse fabrics or the edge of clothing. Using a protective film or full-coated 3D glass will help keep the factory glass in perfect condition.

Update frequency and touchscreen responsiveness

The screen runs at a standard refresh rate of 60Hz. This means that the image is updated 60 times per second. For static content, video viewing and most applications, this is more than enough. The smoothness of MIUI animations at this frequency looks good, although it is inferior to the modern 90Hz and 120Hz panels that have become the standard in newer models.

The touchscreen is very sensitive and supports multi-touching up to 10 touches at a time, which is important for gaming and image zooming, and the input lag is minimal, which makes game control predictable, but in heavy-duty environments. 3D-games with high load on the processor can be observed micro-freeze associated not with the screen, and with the performance of iron.

Done: 0 / 4

It's worth noting that there's a proximity sensor that's optical in this model, not physical, which makes the top frame thinner, but sometimes leads to false alarms when you talk, if your cheek touches a certain area of the screen.

Display settings in MIUI system

The MIUI system shell provides a wide range of tools for setting up the screen. In Settings โ†’ Screen, the user can adjust not only brightness but also color temperature balance by shifting the slider from warm to cold. Read Mode is also available, which turns the screen into an e-book using software filters.

And the Adaptive Brightness feature, which is learning the user's habits, is that if you manually dim the brightness in a particular place, the phone will remember that and the next time it does it automatically, which increases the comfort of use and saves battery life.

For those who want to get the most detail of the text, in the advanced settings you can enable "Definition Improvement" (if available in the software version), although on IPS-matrixes with high PPI, the effect of this feature is minimal.

  • โฑ๏ธ Time Out: Adjusting time to screen shutdown (15 seconds to 10 minutes).

โš ๏ธ Attention: Ultra-Economies mode often turns off adaptive brightness and reduces the interface frame rate to save charge, which can make working with the phone less pleasant.

Redmi Note screen 8T โ€” It is a balanced solution of FullHD.+ IPS, which offers excellent clarity and color reproduction, second only in contrast black to modern AMOLED-panel.

Possible screen problems and defects

Despite the overall high quality, the model has specific features, and some users note the crunchy screen effect when pressed hard on the matrix. IPS-panels of a certain type and are not a defect if the screen continues to work correctly after the pressure is removed.

There may also be irregularities in the edges of the lighting, especially when black backgrounds are in the dark, which is considered normal for mass production within acceptable limits, but if the lights are noticeable in normal use, this may be a reason for warranty replacement.

Another rare but possible problem is a green hue at a minimum brightness, a calibration software bug that can sometimes be treated by updating the firmware or resetting it to factory settings, and if the problem is hardware, only a service center can help.

Why does the screen turn yellow over time?
Yellowing IPS-Matrices are a natural process of degradation of organic components of backlights and filters under the influence of heat and ultraviolet light, a process that usually takes several years of active use in Xiaomi smartphones. Accelerate it can be the constant use of the smartphone at maximum brightness in hot conditions.
How to check broken pixels?
To check, open solid white, black, red, green and blue images to the full screen. Carefully examine the surface as you zoom in. Broken pixels will be visible as black (dead) or colored (stuck) dots that do not change color with the background. One or two broken pixels are often not considered an ISO warranty case.
Can I replace the screen myself?
Replacing the screen with the Redmi Note 8T requires skills and tools. The screen is glued to the frame, and you need a hair dryer, suction cups and mediators to disassemble it. The risk of damaging the plumes or the back cover is high. It is recommended that the replacement be done only in an authorized service center, where the original module is used.
Does the protective glass affect sensitivity?
High-quality protective glass (0.3 mm) has little effect on the performance of the touchscreen. Cheap thick glasses (more than 0.5 mm) or glass with a poor adhesive layer can reduce sensitivity, especially at the edges, in which case recalibration or replacement of the accessory helps.
