Xiaomi TVs are not just a budget alternative to premium brands, but full-fledged multimedia centers with advanced image calibration capabilities. 4K HDR or QLED It's not going to show its full potential if the screen settings are set up randomly. A common mistake users make is to use a factory profile called Standard or Dynamic, which often overstates brightness and saturation by distorting natural colors.
In this article, we will understand how to properly adjust the image quality on Xiaomi Mi TVs. TV 4/4S/4A, Mi TV Q1/Q2, Redmi Smart TV And it's all about basics like brightness and contrast, and hidden options for power users, and you'll learn what modes are right for movies, for games on consoles (PS5/Xbox) And sports broadcasts, and how to avoid common mistakes, like scorched pixels from overlits.

1. Preparation of the TV before setting up
Before diving into the settings menu, make sure that external factors do not distort the perception of the picture. Even a perfectly calibrated TV will look bad when the lighting is wrong or the signal sources are not connected correctly.
Here’s what to do before you start setting up:
- 🔌 Connect the TV to the network via a voltage stabilizer – power surges can knock down factory profiles.
- 🌡️ Let the TV warm up for 15-20 minutes – a cold matrix can display colors less accurately.
- 📺 Use quality. HDMI-cable 2.0 or 2.1 for 4K@120Hz). Cheap cables often cut the color range.
- 💡 Adjust the lighting in the room: avoid direct sunlight on the screen and bright light sources behind the TV.
If you connect external devices (set-top box, game console, media player), check their signal output settings. PS5 Xbox Series X needs to manually enable mode 4K HDR System settings – otherwise the TV will not get full dynamic range.
⚠️ Note: If you are using Android TV Box (e.g. Xiaomi Mi Box S), first update its firmware.Older versions often transmit signals in the wrong color space (YCbCr 4:2:0 instead of 4:4:4).
2. Basic image settings: brightness, contrast, sharpness
Let's start with the basic parameters that affect the perception of the picture the most. TV They're on the way:
Settings → Picture → Main settings
Let’s look at each parameter in detail:
| Parameter | Recommended value | What happens if you overdo it? |
|---|---|---|
| Brightness | 45–55 (for dark room) 55–65 (for bright room) | Too high brightness “clogs” dark details (for example, in space in the movie “Interstellar”). |
| Contrast | 80-90 (for) OLED)70-80 (for) LED) | Inflated contrast leads to the “burnout” of light areas (for example, clouds in the sky become white spots). |
| Sharpness | 0-10 (maximum 20 for text) | Excessive sharpness creates artificial halos around objects (especially noticeable on the faces of actors). |
| Color temperature | Warm (6500K) or standard | The cold mode adds a blue tint, which tires the eyes with prolonged viewing. |
To fine-tune the brightness, use a test pattern (which can be found on YouTube for "calibration test pattern"). Adjust the brightness so that the black bars on the pattern are distinguishable but do not merge into gray mass.

⚠️ Note: On Xiaomi TVs with a matrix VA (Most models, high brightness can cause colors to fade when viewed from an angle. If you're looking at a company, reduce the brightness by 10 to 15 units.
☑️ Checking basic settings
3. Image modes: which to choose for movies, games and sports
Xiaomi TV It offers several pre-configured image profiles:
Settings → Picture → Image mode
Let’s look at each regime and its purpose:
- 🎬 Movies – optimized for films with extended dynamic range (HDR). Reduces brightness and saturation for a natural picture, the best choice for watching a movie in a dark room.
- 🎮 Play: Reduces input lag and increases sharpness. ALLM (Auto Low Latency Mode for consoles. Use only for games! For movies, the picture will be too hard".
- ⚽ Sport - increases brightness and saturation, so that the green field of the stadium looks juicier, suitable for daytime watching matches.
- 🌈 Live - the brightest and most saturated profile. Not recommended for long-term use - quickly tires the eyes.

How to check the input delay (input lag)?
4. Advanced settings: color gamma, gamma and noise cancellation
For those who want to make the most of their TV, MIUI TV There are hidden calibration options:
Settings → Picture → Additional settings
Let’s look at the key parameters:
- 🎨 Color coverage: The TV chooses between the two BT.709 (SD/HDR) and BT.2020 (4K HDR). BT.2020 — only 4K HDR-content (Netflix, Disney)+, Blu-ray). BT.709 — regular full HD-Error: If you turn on the content BT.2020 not-HDR content, the colors will be dull.
- 📊 Gamma: 2.2 is the standard for most movies. 2.4 for dark rooms (increases detail in the shadows). Tip: For games, choose 2.2 - a more natural picture.
- 🔇 Noise suppression: Turn off for 4K-content – Xiaomi algorithms can blur details. turn on low for terrestrial TV or compressed streams (e.g, 720p YouTube).
Pay special attention to setting up local dimming on models with Full Array LED (Like Mi. TV Q1 75) This feature improves contrast, but can create "blooming" (glow around bright objects.
💡
If after setting the colors seem unnatural, reset the image settings to factory (Settings) → Picture → Reset) and start over. Often the problem is the conflict of manual settings with automatic profiles.
5.Tune in. HDR Dolby Vision: How to Get the Most of It 4K

- 📱 Calibration applications: CalMAN (paid, for experts). DisplayCAL (free, requires colorimeter). THX Tune-Up (free, with test templates).
- 🖥️ Hardware calibrators: X-Rite i1Display Pro (~$200). Datacolor SpyderX (~$Connect to a PC that gives test signals to the TV.
For basic calibration, without equipment, a method using YouTube test videos is suitable.
- Include a test video with gray gradients (for example, "Gray Scale Calibration").
- Adjust the brightness so that the black color is really black, but without losing detail in dark areas.
- Adjust the contrast so that the white color does not “glow” and does not lose textures.
- Check the color balance from the test picture with shades of gray – all squares should look neutral, without a greenish or reddish hue.
If you use Kodi or Plex to watch movies, you also need to select the right renderer in the player settings (e.g. AMCodecs for Xiaomi). TV) and turn off post-processing of video.
