HDR in Xiaomi TV: A Complete Guide to Technology, Customization, and Content Selection

You have bought a new Xiaomi TV with support HDR, But you don't understand why it's sometimes dim and sometimes incredibly bright and detailed, or maybe you just pick a model and you want to figure out whether you should overpay for this technology? HDR Xiaomi TVs, how it works in practice, what formats are supported (from the Internet) HDR10 Dolby Vision, and why even with the HDR-You may not get the promised effect from the manufacturer.

What is HDR and how is it different from SDR?

HDR (High Dynamic Range) is a technology that extends the range between the darkest and brightest areas of an image. Unlike the traditional SDR (Standard Dynamic Range), where the brightness is limited to ~100 nits, HDR can exhibit peak brightness up to 1000-4000 nits (depending on the TV model).

• 🎨 A wider color coverage: HDR uses the Rec. 2020 space or DCIP3, This allows you to display up to 1 billion shades (against) ~16 million SDR).
• 🔍 More details in the shadows and light areas: SDR-The sky at sunset may be just a white spot, and the sky at sunset may be a white spot. HDR You'll see clouds and gradients.
• 🖼️ 10 or 12-bit color depth: vs. 8 bits in SDR, which excludes banding (banding) on gradients.
• 💡 Dynamic adjustment to the scene: in Dolby Vision, brightness and contrast are adjusted for each frame separately.

It's important to understand that Dolby Vision isn't just "enhanced HDR10"; it's a separate standard with dynamic correction of each frame, which is especially noticeable in scenes with rapid lighting changes (for example, transitioning from a dark room to bright sunlight).

• 📺 Dolby Vision-enabled TV (check out the specifications of your model!).

Optimal values for most Xiaomi TVs: Brightness: 45-55% (depending on the lighting in the room). Contrast: 90-100% (but not maximum, otherwise parts will be lost in the shadows). Gamma: 2.2-2.4 (standard for the room lighting). HDR-content).
