The TV market today is saturated with marketing terms that often confuse the average consumer. Among the many acronyms, one of the most significant is HDR, which literally translates as High Dynamic Range. Xiaomi device owners, whether it is the budget model of the Mi TV P1 or the flagship QLED, constantly see this icon in the settings menu or on the box, but do not always understand its real impact on the picture.
In simple terms, High Dynamic Range is a technology that allows you to display a wider range of brightness and color in a single frame. Whereas previously screens were limited to the SDR standard, where black often looked gray and bright highlights were simply “glowed”, the new panels are able to show details in the darkest and brightest areas at the same time. For Xiaomi TVs, this is especially true, as the brand is actively implementing support for Dolby Vision and HDR10+ even in the mid-range segment.
In this article, we will take a closer look at how this technology works in the Android TV and PatchWall ecosystem, where you will learn the difference between different formats, why some models do not “pull” the stated standard, and how to properly configure image settings to get the most out of your device without overpaying for unnecessary features.
The essence of technology and the principle of operation of High Dynamic Range
The basic principle of HDR is to increase the bit content of the image. Standard TV (SDR) uses 8 bits per color channel, which gives only 16.7 million shades. This is often not enough for smooth gradients, which causes so-called "steps" or posterization. Xiaomi HDR-enabled TVs move to 10-bit color depth, providing already more than 1 billion shades, which makes the picture incredibly realistic.
The key is not just the number of colors, but the contrast, and the technology allows you to simultaneously display very dark areas of a scene with visible detail and very bright, without knocking them out in pure white, using metadata that is transmitted along with the video stream and instruct the TV on each frame or scene.
It’s important to understand that having an HDR-enabled matrix doesn’t guarantee a perfect picture. Xiaomi’s budget models, such as the Mi TV 4A series, often use software emulation. The real effect is only noticeable when the physical brightness of the panel (measured in threads) and local dimming allow the technology to realize its potential.
💡
To test the real HDR on your Xiaomi, download the “HDR10+ Video Test” app from Google Play and run a test video to see if the panel supports hardware decoding.
The difference between normal and extended dynamic range becomes apparent when watching movies with dark scenes or space scenes. SDR-On the screen you will see a black spot, HDR-TV will show the texture of a rock or star in the background.
The main HDR formats in Xiaomi TVs
The world of high dynamic range is not unified, and manufacturers use different standards. Xiaomi in their devices often supports several formats, making them versatile for viewing content from different sources.
The first and most common is HDR10, which is an open source base standard that uses static metadata, which means that brightness and contrast settings are set once for the entire movie or episode, and most models, including the Mi TV Stick and the Mi Box S, are guaranteed to support this format.
A more advanced version is Dolby Vision. Unlike HDR10, this format uses dynamic metadata to adjust the image frame by frame, which allows you to achieve better detail in each specific scene. flagship models Xiaomi, such as Mi QLED TV 55 or Mi TV 6 Extreme Edition, often have Dolby Vision certification, which significantly increases their cost and quality of the picture.
- 🎬 HDR10: Basic standard, static settings, supported by all streaming services.
- 🌈 Dolby Vision: Dynamic correction, better quality, requires licensing (often found in top Xiaomi).
- ⚙️ HDR10+: Open source analogue of Dolby Vision, dynamic metadata, less common in Xiaomi lineup.
- 📺 HLG (Hybrid Log-Gamma: A digital TV format that does not require metadata.
It’s worth noting that having a logo on the box doesn’t always mean the same performance. Cheap panels can decode the Dolby Vision signal, but because of the low peak brightness (less than 300-400 nits), you won’t see the depth that the content creators intended.
Hardware requirements and impact on picture quality
For the full operation of the technology of extended dynamic range, just a decoder in the processor is not enough. The physical characteristics of the matrix are critical. Xiaomi TVs use different hardware, and this directly affects the final result. If you are planning to buy, be sure to pay attention to the type of backlight and peak brightness.
The ideal scenario for HDR is to use Full Array Local Dimming (FLED) IPS panels or VA matrices with high contrast. The Mi TV Q1 series uses quantum dot technology (QLED), which in combination with HDR gives rich colors. However, budget series often feature Edge-LED screens where black can glow at the edges, negating the benefits of HDR.
⚠️ Please note: Do not expect miracles from HDR In models with a brightness of less than 300 nits, in such cases, the TV simply displays the signal, but visually the difference between the two is the same. SDR It will be minimal or even invisible.
The chipsets from MediaTek (such as the MT9652), which are often found in new Xiaomi, have built-in image processing units that can scale low-resolution content to HDR-like quality, a process called upscaling, and it helps improve the picture from cable TV or old videos.
For gamers, support for VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) in conjunction with HDR is critical. Game modes on Xiaomi TV allow you to activate these functions automatically when you connect the Xbox Series X or PlayStation 5 consoles, providing a smooth picture without tears.
Comparison of standards: characteristics table
To organize the information and understand which standard is best for your tasks, let’s turn to a comparative table that will help you quickly navigate the technical differences in the formats supported by Xiaomi’s technology.
| Characteristics | HDR10 | Dolby Vision | HLG | HDR10+ |
|---|---|---|---|---|
| Type of metadata | Static | Dynamic | No (hybrid) | Dynamic |
| Depth of color | 10 bits | 12 bits | 10 bits | 10 bits |
| Max. brightness. | 10,000 nits | 10,000 nits | 10,000 nits | 10,000 nits |
| License. | Free. | Paid | Free. | Free. |
| Popularity in Xiaomi | 100% models | Middle and Top | All Smart TVs. | Rarely. |
As you can see from the table, Dolby Vision is technically superior to the base HDR10 due to greater color depth and dynamic control, but for the average user, the difference may not be so obvious if you do not use a quality signal source.
Interestingly, the standard HLG It was designed specifically for television, if you're watching on-air channels through a digital set-top box or a built-in tuner. DVB-T2 Xiaomi Mi TV, You can already get HDR-The image is provided if the channel supports this format.
Customize the image for maximum effect
After buying a Xiaomi TV, you often need to manually adjust, as factory settings ("Store Mode") are usually too bright and unnatural. To unlock the potential of HDR, you need to go to the image settings menu.
Go to the Settings section → Image: → Image mode. HDR-The content automatically activates a special mode, but its parameters can be adjusted. It is recommended to use the "Movie" or "Filmmaker Mode" mode, as they most accurately convey the colors specified by the director.
☑️ Setting up HDR
An important step is to disable various “improvers” that can distort the picture. Functions like “Noise Reduction” or “Dynamic Contrast” (if it is not part of hardware HDR) are better to minimize or turn off. It is also worth checking the HDMI settings. Make sure that the Settings → General → External inputs for the corresponding port are set to HDMI 2.0 or HDMI 2.1 mode, rather than the older standard.
⚠️ Attention: When the mode is activated HDR The brightness of the screen can automatically increase to a maximum. This is normal for this technology, but can lead to increased power consumption and heating of the case during prolonged viewing.
You can use built-in test images to calibrate the color or download special YouTube videos in 4K HDR. Set the Color Temperature to Warm or Warm, as the D65 (6500K) standard is the reference for the film industry, although at first the picture may appear yellowish.
Where to watch content in high dynamic range
Having a TV is only half the story. To see the difference, you need relevant content. Fortunately, with the development of streaming services, finding material in 4K HDR is becoming easier. Xiaomi's Android TV operating system provides access to most popular platforms.
Leader by number HDR-The content is Netflix. Virtually all of their original series (Stranger Things, The Witcher) are available on Dolby Vision. You can also see YouTube, where many channels upload test videos and documentaries to the public. 4K HDR. Amazon Prime Video is also actively used. HDR10+.
The secret to activating hidden modes
If you use external devices such as game consoles or media players, make sure that their video settings also activate HDR signal transmission. Often the TV is ready, the console is ready, but the Xbox or PS5 settings have an automatic mode that does not switch to HDR.
Local files can also be played from a flash drive or through a DLNA-It's best done with an embedded player or an application like that. VLC for Android or Kodi, which can correctly process metadata and switch the modes of the matrix on the fly.
💡
The quality of the image is 80% dependent on the source of the signal: even the best Xiaomi TV will not show HDR if you watch compressed low-bitrate video.
