Core definition: AG (Anti‑Glare) technology uses micro‑textured surfaces to turn specular reflection into diffuse reflection, solving glare problems under bright light. The industry standard “AG+number” indicates the anti‑glare level – higher number means stronger glare reduction but more haze.
Core levels: AG25 (low haze, clear, for office/design), AG33 (balanced, for gaming/home), AG50+ (strong anti‑glare, for outdoor/bright light). AG33 is the sweet spot for most users.
Key parameters: Haze (determines glare reduction & fogginess), Gloss (inversely related to haze), Roughness (affects scattering smoothness), Transmittance (affects image clarity) – essential specs when buying an AG screen.
AG vs AR: AG uses physical scattering (durable, lower cost, slight haze); AR uses optical thin‑film interference (no haze, higher cost, easier to scratch). AG33 offers stronger glare reduction than AG25 with slightly more haze, suitable for more scenarios.
Buying tips: Choose AG level by usage scenario, match haze to resolution, use hoods/low‑reflection desks for better effect, and clean AG coatings properly.

Quick Selection Table: AG Levels at a Glance
AG Level | Haze (%) | Gloss (60° GU) | Glare Reduction | Image Clarity | Best Use Cases | Priority |
AG25 | 20–28 | 45–60 | Mild | Clear, nearly no haze | Office, design, low‑light indoor | First choice for 1080p, max clarity |
AG33 | 30–35 | 30–40 | Balanced | Slight haze, good clarity | Gaming, home, mixed light (indoor + window) | Top pick for 2K/4K, most daily use |
AG50 | 45–55 | 15–25 | Strong | Noticeable haze | Outdoor, high‑glare environments, industrial | On‑demand (only for bright light) |
AG70+ | 60+ | <15 | Extreme | Heavy haze, soft details | Extreme glare, industrial displays | Special‑purpose only (not for daily) |
Display anti‑glare (AG) technology uses surface micro‑structuring to scatter ambient light, solving the problem of blinding reflections under bright light. AG33 is the industry‑standard glare rating – the number indicates glare strength and haze level.
The essence of AG (Anti‑Glare) is turning specular reflection into diffuse reflection, preventing strong light from reflecting directly into your eyes.
How it’s made: Chemical etching or spraying micro‑particle coatings on the glass/panel surface to create nano‑scale bumps and valleys.
Effect: Ambient light is scattered evenly, eliminating harsh bright spots. The trade‑off is a slight haze on the screen.
AG vs AR: AR uses optical interference from thin films – almost no haze, but expensive and easy to scratch. AG uses physical scattering – durable, lower cost, but with some haze.
AG33 is the most common anti‑glare rating in monitors and glass panels, written as AG + number (e.g., AG25, AG33, AG50).
Meaning of the number: It represents haze level and glare reduction strength – higher number = stronger glare reduction + more haze.
AG33 standard specifications:
Haze: ≈ 30–35% (mainstream range)
Gloss: ≈ 30–40 GU (measured at 60°)
Roughness (Ra): ≈ 0.2–0.3 μm
Reflectance: ≤ 2% (ordinary glass ≈ 8%)
AG Level | Haze (%) | Gloss (60° GU) | Glare Reduction | Image Clarity | Best Use Cases |
AG25 | 20–28 | 45–60 | Mild | Clear, nearly no haze | Office, design, low‑light indoor |
AG33 | 30–35 | 30–40 | Balanced | Slight haze, good clarity | Gaming, home, general office |
AG50 | 45–55 | 15–25 | Strong | Noticeable haze | Outdoor, high‑glare, industrial |
AG70+ | 60+ | <15 | Extreme | Heavy haze, soft details | Extreme glare, industrial |
Based on mainstream products and verified parameters, here are recommended models for each AG level.
(1) AG25 (Low Haze, Clear – Office/Design)
Skyworth A7H Series (display/TV panel): Features “Picture‑Perfect Screen” with AG25 coating (≈25% haze, ~50 GU). Mini‑LED with high zone count delivers clear, nearly haze‑free image. Ideal for indoor office/design. 144Hz refresh rate also handles light gaming. A versatile AG25 choice.
Dell U2723QX: Professional design monitor with AG25 coating (≈26% haze). 90% transmittance, color accuracy ΔE <2. Perfect for long design or document work – no eye strain. Low‑reflection base enhances indoor experience.
(2) AG33 (Balanced – Gaming/Home)
Skyworth A10H Pro Wallpaper TV: Co‑developed with BOE, features “Borderless Screen” with dual AG33 layers + dual LR low‑reflection layers. Haze ≈33%, gloss ~35 GU, reflectance as low as 0.7% – no fear of window glare. 11520‑zone Mini‑LED and 103% BT.2020 color gamut. Perfect for gaming and home cinema.
AOC AG246FK: Gaming monitor with clear AG33 rating. 24.1″ TN panel, 400 cd/m². Balanced glare reduction – slight haze doesn’t hurt game visuals. Great value for 2K high‑refresh gaming and everyday office use.
ASUS ROG Strix XG27AQM: 27″ 2K 270Hz gaming screen, AG33 coating (≈32% haze), fine texture without graininess. No harsh reflections under bright light. HDR400 support. Ideal for home and gaming mixed use.
Haze (%)
Definition: Percentage of transmitted light that is scattered away from the original direction.
Meaning: Higher haze = stronger glare reduction + more foggy appearance. AG33 corresponds to ≈33% haze.
Guideline: Office/design ≤30%; gaming/home 30–40% is the sweet spot.
Gloss (GU)
Definition: Surface reflectivity measured at 60°. Higher value (100+ GU) means more mirror‑like reflection.
Relationship: Gloss is inversely proportional to haze. AG33 has ≈35 GU, far below a mirror’s 100+ GU.
Roughness (Ra, μm)
Definition: Average height of microscopic peaks and valleys – determines how finely light is scattered.
AG33: Ra ≈ 0.2–0.3 μm, fine texture with no visible graininess.
Transmittance (%)
Definition: Ratio of light passing through the panel to incident light.
AG33: Typically 88–91%, slightly lower than bare glass (≈92%), but unnoticeable in daily use.
Pros
Balanced glare reduction: Not blinding in bright light, not too dull indoors – the most versatile AG level.
Good durability: Etched or coated surface resists wear, more scratch‑resistant and easier to clean than AR coatings.
Moderate cost: Cheaper than low‑haze AG or AR coatings – great value.
Cons
Slight haze: Text and image edges are slightly softened, less noticeable at high resolutions.
Dark areas a bit gray: Blacks aren’t perfectly deep, minor impact on HDR or professional video work.
Best use cases
Gaming monitors (27″ 2K/4K high refresh rate)
Home/office monitors (indoor + window mixed light)
Laptops, all‑in‑one PCs
Bright environments where absolute sharpness isn’t critical
Choose AG level by scenario: Office/design → AG25; daily/gaming → AG33; outdoor/bright light → AG50+.
Match haze to resolution: 2K/4K can safely use AG33 – high pixel density cancels out haze. For 1080p or lower, prefer AG25.
Combine with accessories: AG screen + hood/low‑reflection desk doubles the anti‑glare effect. Avoid placing screen directly facing windows or lights.
Cleaning: Use a microfiber cloth + clean water. Never use alcohol or strong acids – they damage the AG coating.
AG33 is the golden balance in display anti‑glare: about 33% haze, it effectively reduces strong‑light reflections while preserving sufficient image clarity. It’s the right choice for the vast majority of users. When shopping, prioritize haze / gloss specs, then match the AG level to your usage scenario – and you’ll find the perfect balance between glare control and image quality.
