How to Improve Image Quality on Xiaomi TV: From Basic Settings to Hidden Chips

Xiaomi TVs are a combination of affordable prices and advanced technology, but even the top models (such as the Mi TV Q2 or Redmi Smart Fire TV) sometimes disappoint with an out-of-the-box picture. Dim colors, blurred contours, wrong color temperature - these problems are faced by one in three owners, the reason lies not in the "curve" matrix, but in factory settings focused on the "average" user.

In this article, we will not talk about how to turn on the TV or connect it. HDMI-Instead, we'll look at 7 practices that really affect image quality, from calibration through the service menu to the hardware constraints of specific models. You will learn why the setup of the "Kino" in 90% of cases worsens the picture instead of improving, how to get around the limitations of budget panels and when to contact the service center. All instructions are tested on models 2020-2026, but most tips are relevant for older TVs.

Basic image settings: what to change first

Start with the Settings menu → Display and sound → Image. Here are the parameters that instantly transform the picture — but only if you know which values to choose.

The most common mistake is to use preset modes ("Standard", "Cinema", "Dynamic"), which are optimized for specific scenarios (for example, "Cinema" darkens the image for cinemas), but at home they often distort colors.

• 🔍 Select the User mode – it allows you to fine-tune each setting.
• 🎨 Set the color temperature to normal (6500K) — This is the standard for most content.
• 🌡️ Turn off Auto Brightness and Light Sensor – these often malfunction, especially in Redmi models TV.
• 🖼️ Turn on Local Dimming (if any in your model) to improve contrast in dark scenes.

Pay special attention to the Sharpness parameter. Many users put it at its maximum in hopes of getting a clear picture, but this leads to artifacts (for example, white halos around objects). The optimal value is 30-50% of the scale. To check the result, turn on a test video with small details (for example, grass or textures of buildings).

2. Color calibration: how to get rid of greenish or reddish hue

Color reproduction is one of the main complaints of Xiaomi TV owners, for example, Mi TV 4S and Mi TV P1 often sin with excess green, and Redmi Smart TV X – red, this can be corrected through manual color adjustment.

Go to Settings → Display and Sound → Image → Additional → Color Balance. Here you will see three sliders: Red, Green and Blue.

1. Enable a test image with gray gradients (can be found on YouTube for "gray scale test pattern").
2. Make sure all shades of gray look neutral, without color shifting.
3. Adjust sliders in turn, starting with green (it most often requires reduction).

If your model does not have manual color balance adjustment, use an alternative method:

• 📊 Set a color profile on sRGB (if available) – it’s closer to natural colors.
• 🔄 Turn off all the image enhancers: Super Resolution, Dynamic Contrast, Color Enhancement. They artificially saturate colors, but distort them.

💡

To check color rendering, use color-tested videos (e.g., SMPTE Color Bars) and if blue looks purple and red looks orange, calibration is required.

3. HDR and Dolby Vision Setup: Why Your Xiaomi TV Doesn't Show "Real" HDR

Xiaomi TVs support HDR10, HLG and Dolby Vision, but not all users see the difference between these formats, often the problem lies in the wrong settings of the signal source (for example, consoles or game console).

To activate full HDR:

1. Make sure your source (such as Apple) is your source. TV 4K or PS5) conclusion-set HDR. In the device menu, find the parameters Out of the video or HDMI-set up HDR10 Or Dolby Vision.
2. On the TV, go to Settings. → Display and sound → HDMI-Mode and select Enhanced format for the port to which the source is connected.
3. Include the setting in the image menu HDR-Mode (sometimes hidden in Additional settings).

Note that Xiaomi’s budget models (such as the Mi TV 4A) are physically unable to reproduce the full range of HDR brightness due to the limitations of the matrix. In such cases, turning on HDR can even worsen the picture, making it dim. Check the specifications of your model on the official website.

💡

Dolby Vision requires not only TV support, but also compatible TV support. HDMI-If you turn on Dolby Vision, the picture flashes or disappears, replace the cable.

Hidden settings MIUI TV: how to turn on the engineering menu

Xiaomi TVs have a service menu where you can fine-tune matrix settings that are not available in the standard interface. This menu is for engineers, so you only need to change the settings if you understand what they're responsible for.

To open the engineering menu:

1. On the remote, tap sequentially: Menu → Settings → All Settings → General → Device Preferences → About → Press 5 times on Model TV.
2. You will see a message that says, “You’ve become a developer.” Go back to the main menu and open Settings → Developer.
3. Activate the Engineering menu option.

In the engineering menu you will find sections:

• 📺 Panel Settings – Matrix adjustment (e.g., gamma curve correction).
• 🎛️ Color Management – Extended color calibration (including Kelvin color temperature).
• 🔧 HDMI Debug - Debugging the signal HDMI (It is useful if the image is "torn»).

⚠️ Warning: Incorrect settings in the engineering menu can lead to irreversible image degradation or even failure of the TV. Before changing, take a picture of the current values or write them down.

5. Hardware restrictions: when settings will not help

Some image problems are not software-based, and they are related to the physical features of the matrix or the electronic components.

• 🔦 Backlight with defects (backlight): On budget models (Mi) TV 4C, Redmi TV A) there is often uneven backlighting, especially at the edges of the screen. This is a matrix defect, and it can only be corrected by replacing the panel.
• 🖥️ Low resolution matrix: If your TV has a resolution 1366×768 (Like Mi. TV 4A 32"), No amount of customization will make the picture clear when viewed. 4K-In this case, only an upgrade to the model with the content will help. 3840×2160.
• 🔄 Factory marriage: Vertical or horizontal bands, broken pixels are a reason for warranty repair. Check the matrix for broken pixels with a test video (for example, "Dead Pixel Test»).

If you suspect a hardware problem, do a simple test:

1. Connect the TV to another signal source (e.g., a laptop via HDMI).
2. If defects remain (such as blur or stripes), the problem is in the TV's array or electronics.
3. If the picture is clean, the source of the signal (prefix, console, cable) is to blame.

⚠️ Attention: If your Xiaomi TV Released until 2019 and has a type matrix VA, Don't expect perfect viewing angles. When you look from the side, the colors will be distorted, which is normal for this technology.

6.Optimization for games and movies: separate profiles for different scenarios

The same TV can show differently depending on the content, for example, for games, minimum input delay is important, for movies, accurate color reproduction is important, and set up separate profiles for each scenario.

For games (PS5, Xbox, PC):

• 🎮 Turn on Game Mode in the image settings – this will reduce the input delay to 10-15 ms.
• 🔄 Disable all post-processing: Motion Smoothing, Noise Reduction, Sharpness (set to 0).
• 🖥️ Set the permit. 4K at 60 Hz or 120 Hz (if supported). PS5 Select in the console settings Video output → Permission: 2160p.

For movies and TV shows:

• 🎬 Turn on Movie Mode (if any) or create a custom profile with options: Brightness: 45-55% (depending on room lighting). Contrast: 85-90%. Color temperature: Warm (for more natural skin tones).
• 🎞️ Turn it on. 24p Smooth (if available) – this will eliminate jitters when watching 24-fps movies.

Game mode on.

Motion Smoothing is off.

The resolution is set to a maximum (4K/120 Hz)

HDMI-cable 2.1 (for 4K@120Hz)-->

7. firmware update and settings reset: when it really helps

If the image is not good after all the manipulations, the problem may be software errors. Regular firmware updates from Xiaomi often fix bugs with color reproduction, HDR support and signal processing.

To update the firmware:

1. Go to Settings → About TV → System Update.
2. Click Check Updates. If a new version is available, install it.
3. After the update, reset the image settings to factory (Settings → Display and sound → Reset image settings).

If the update didn’t work, try a full reset of the TV (all data will be deleted!):

Settings → About TV → Reset to factory settings

It's a radical method, but it often solves problems with artifacts, color renderings, and interface glitches, and after resetting, you'll have to reconfigure your Wi-Fi, accounts, and image settings.

⚠️ Note: If after updating the firmware TV began to spontaneously switch modes of the image (for example, with the HDR on SDR), This can be a bug of a particular version of the software. The rollback to the previous firmware is possible only through the service center.
