Mini-LED 背光相較傳統(tǒng) LED 在對(duì)比度、亮度和局部調(diào)光上有顯著提升。1. 更深的黑色和更高的對(duì)比度：AG275UXM 通過(guò)數(shù)千個(gè)微型 LED 實(shí)現(xiàn)更精確的照明控制，減少光暈現(xiàn)象，提升陰影細(xì)節(jié)與 HDR 動(dòng)態(tài)范圍；2. 更高的峰值亮度與持續(xù)表現(xiàn)：相比傳統(tǒng) LED，Mini-LED 可在更大面積上維持高亮度，增強(qiáng) HDR10 內(nèi)容的色彩準(zhǔn)確性與亮度均勻性；3. 更精細(xì)的局部調(diào)光：AG275UXM 擁有數(shù)百個(gè)調(diào)光區(qū)，實(shí)現(xiàn)更細(xì)膩的光影控制，減少亮物體周圍的光暈并增強(qiáng)視覺(jué)深度；盡管仍可能存在輕微光暈及黑位不及 OLED，但對(duì)大多數(shù)用戶而言，其畫質(zhì)提升足以值得升級(jí)。

The Mini-LED implementation on the AG275UXM offers a significant step up from standard LED backlighting, especially in terms of contrast, brightness, and local dimming performance. If you're trying to decide whether this monitor’s display tech is worth it or if a regular LED-lit screen would do, here's what you really need to know.

Better Contrast and Deeper Blacks

Mini-LED uses thousands of tiny LEDs—much smaller than those in traditional backlights—which means more precise lighting control. On the AG275UXM, this translates into deeper blacks and better contrast because the backlight can dim in very specific zones without bleeding light into darker areas.

Standard LED setups usually have fewer, larger LEDs, so dimming isn’t as refined. You might notice blooming around bright objects on dark backgrounds, which is much less of an issue with Mini-LED.

• More defined shadow detail in games and movies
• Less light bleed in high-contrast scenes
• Improved dynamic range for HDR content

Brightness That Stands Out

One of the biggest advantages of Mini-LED is its ability to hit and sustain higher peak brightness levels. The AG275UXM takes advantage of this by delivering strong HDR performance—especially noticeable in well-mastered HDR content where highlights like sunlight or explosions pop more vividly.

Regular LED backlights can get bright, but they often struggle to maintain that brightness across large portions of the screen without overheating or dimming dynamically (a process called "power throttling").

• Sustained brightness over larger areas
• Better HDR10 support with more accurate color volume
• Visible improvement in real-world brightness uniformity

Local Dimming Done Right

Local dimming is where Mini-LED really shines. The AG275UXM has hundreds of dimming zones (sometimes referred to as “full-array” local dimming), allowing it to adjust brightness more precisely based on what’s on-screen. This results in better image depth and realism.

With standard LED monitors, even those with basic local dimming, the number of zones is usually much lower, making it harder to avoid haloing effects or uneven lighting during darker scenes.

• Smaller zones = finer control over lighting
• Reduced halos around bright objects
• Improved perception of depth in visuals

Not Perfect, But Worth It for Most

That said, Mini-LED isn't perfect. You might still see some minor blooming in certain scenes, especially if the content isn’t optimized or if the dimming settings are too aggressive. Also, while black levels are better than standard LED, they’re not quite OLED-level. But for most users—especially gamers or multimedia fans—the improvements are more than enough to justify the upgrade.

So if you're comparing the AG275UXM’s Mini-LED panel to a standard LED monitor, the difference matters—especially if you care about HDR, contrast, and overall visual fidelity.

基本上就這些。
