Summary of the Video “Mini LED и OLED в HDR”

This video presents a detailed comparison between two types of HDR monitors: the ASUS ALED monitor (ASUS XG27AQDMG) and the TCL Mini LED monitor (TCL 27R83U). The focus is on their performance in brightness, contrast, local dimming (local shading), and overall HDR experience.

Key Technological Concepts and Product Features

Monitor Specifications

TCL Mini LED Monitor:
- 27-inch diagonal, 4K resolution, 160 Hz refresh rate.
- VA panel with matte coating.
- Approximately 1100+ local dimming zones (exact number not specified).
- Priced around 52,500 rubles.
- Peak brightness around 1420–1600 nits.
- Consistent brightness regardless of scene content.
ASUS ALED Monitor:
- 26.5-inch diagonal, Quad HD resolution, 240 Hz refresh rate.
- Double violet (OLED-like) panel from LG with glossy coating.
- Each pixel acts as an independent dimming zone (~3.6 million pixels).
- Priced around 65,000 rubles.
- Brightness dynamically adjusts based on scene light (e.g., 440 nits at 5% window, below 300 nits at 100% white).
- True pixel-level brightness and color control.

Backlighting and Local Dimming

Traditional monitors have a single backlight zone.
Mini LED uses many zones (~1100) to improve local dimming.
ALED technology allows each pixel to control its own brightness, eliminating blooming and providing perfect blacks.
TCL Mini LED local dimming has four modes:
- Off: Acts like a regular VA monitor with poor contrast.
- Standard: Combines global and local backlighting; reduces blooming somewhat.
- Medium: Only local dimming active; deeper blacks but noticeable blooming and loss of shadow detail.
- High: More aggressive dimming; further loss of shadow detail and brightness in small light objects.
Blooming (light glow around bright objects) is a major downside for Mini LED, especially in Medium and High modes.
ASUS ALED has no blooming and preserves brightness and shadow details better.

Matrix (Panel) Characteristics

VA panels suffer from flickering in dark gray areas and have a viewing-angle contrast effect (a bright spot where the eye looks).
These effects are typical for VA technology.
ALED panel does not exhibit these issues.

Brightness and Contrast Behavior

TCL Mini LED maintains high brightness but struggles with blooming and shadow detail loss.
ASUS ALED dynamically adjusts brightness based on scene content, providing balanced brightness and excellent contrast.
Lowering brightness on Mini LED improves contrast but reduces HDR impact.
Mini LED performs well in large uniform light/dark areas but struggles with complex scenes having many small bright spots.
ALED excels in complex scenes due to pixel-level control.

Dynamic Content and Gaming

Mini LED local dimming can cause noticeable halos and flickering around bright objects during motion or interface changes.
ALED provides stable and clean image quality without halos or flickering.
Mini LED’s aggressive dimming algorithms in Medium and High modes can degrade dynamic content experience.

Color and Calibration

Both monitors have similar color gamuts.
ALED tends to have a blue tint in photos/videos due to shooting artifacts, but this is not noticeable in real use.

Burn-in Risk

OLED/ALED technology has a risk of burn-in, especially with static interface elements and prolonged use at high brightness.
TCL Mini LED has no burn-in risk.
Burn-in statistics for ALED are inconclusive; some tests show burn-in in about six months under extreme conditions.
Users should consider their usage patterns when choosing.

Summary of Conclusions

Mini LED monitors offer a significant upgrade over traditional monitors with higher brightness, better contrast, and HDR support, but suffer from blooming, shadow detail loss, and backlight artifacts.
ALED monitors provide superior contrast, perfect blacks, and excellent detail preservation without blooming but have lower peak brightness and risk of burn-in.
Choice depends on user preference:
- Mini LED is better for those who want high brightness, no burn-in risk, and a more affordable price.
- ALED suits users prioritizing perfect black levels, contrast, and detailed shadow rendering, especially in darker environments.
The TCL Mini LED’s default local dimming mode (Standard) offers the best balance to minimize blooming.
Burn-in remains a concern for ALED users, with no definitive real-world statistics.
