How does diagonal affect image quality and viewing comfort?
Many people mistakenly believe that the larger the diagonal, the better the picture, but it's actually more complicated: the screen size has to match the resolution, the distance to the viewer, and even the lighting in the room.
1.Pixel resolution and density (PPI)
The larger the diagonal at the same resolution, the lower the pixel density (dots per inch).
- 🔍 43-inch-screen 4K (3840×2160) has PPI ≈ 102 — perfect for viewing with 1.5–2.5 meters.
- 🔍 55-inch with the same 4K — PPI ≈ From a close distance (less than 1.8 m) pixels may be visible.
- 🔍 32-inch-inch HD Ready (1366×768) — PPI ≈ 50. When viewed from a distance less than 1.2 I'll have a soapy picture".
💡 Rule: For Full HD optimum distance = diagonal × For 1.6. 4K — diagonal × 1.2 For example, for Mi TV 4X 55"s" 4K ideal distance - 1.6-2.2 meters.
Viewing angles and illumination
On Mi TVs TV 4X used VA-A matrix that provides high contrast but has limited viewing angles (about 170).°). It means:
- 👁️ Large diagonals (65" and 75") when viewed from the side (more than 30)° from the centre) the colours may be “washed out".
- 💡 Models 55" and more use direct lighting (Direct). LED), This improves the brightness uniformity compared to 32" and 40" where edge lighting is applied (Edge) LED).
⚠️ Note: If you are planning to hang up your TV, TV 4X 65" or 75" on the wall in a narrow room, note that when viewing from close range (less than 2.5 m for 65" and 3 m for 75") you will have to constantly turn your head to cover the entire screen.
3. Brightness and HDR
All Mi models TV 4X 43" and above support HDR10, But the real brightness varies:

| 55" | 350 | ✅ HDR10 | Direct LED (12 zones) |
| 65" | 400 | ✅ HDR10 | Direct LED (16 zones) |
For a comfortable viewing HDR-content (such as movies on Netflix or Disney)+) We recommend 55-inch models that provide sufficient brightness and contrast. The smaller diagonals (32" and 40") are only suitable for daytime viewing in good lighting.
