VESA introduced DisplayHDR True Black on January 3, 2019, to certify HDR performance in OLED and other emissive displays using criteria suited to their pixel-level black control. The standard complements the LCD-focused DisplayHDR family; it does not replace it. Its tier number is only one part of the picture, so buyers should verify the exact certification and look beyond the logo when comparing displays.
What VESA introduced in January 2019
The Video Electronics Standards Association (VESA) announced DisplayHDR True Black on January 3, 2019. The new variant was designed for OLED and future emissive technologies such as microLED, whose pixels produce their own light. The initial rollout included True Black 400 and True Black 500. VESA’s announcement archive records the launch at displayhdr.org/pr/page/2/, and its current overview describes the standard at displayhdr.org.
The change addressed a measurement problem: OLED’s defining HDR strength is not just how bright highlights get, but how effectively each pixel can go dark. A certification aimed primarily at backlit LCDs does not express that behavior in the same way.
Why OLED has a different HDR certification
An LCD forms its image with a backlight. Even when local dimming is used, that backlight is divided into zones, so a dark area near a bright object may receive some unwanted light. OLED pixels are emissive and can switch off individually, enabling much lower black luminance and pixel-level contrast.

#1 Best Overall
- Samsung’s 27” Odyssey OLED G6 Gaming Monitor is engineered for perfection with a QD-OLED Display featuring QHD resolution made to deliver high brightness and a wide range of colors for gameplay
- OLED Safeguard technology supports performance by actively helping to prevent burn-in with a thermal modulation system
- Glare Free Technology keeps screen clear of reflection from external light sources
- The Pantone Validated screen accurately reproduces 2100+ lifelike colors and 110+ skin tone shades
- HDR10 provides brighter highlights and nuanced shadows for added depth and more realistic scenes
That distinction affects how a display should be judged. An OLED can produce striking contrast and shadow detail without matching the full-screen brightness of a high-brightness LCD. Conversely, a high peak-brightness number alone does not establish how well a display renders dark scenes, color, or transitions.
VESA describes True Black as optimized for emissive displays, emphasizing low black levels, dynamic range, and rise time. VESA has also claimed up to 100-times deeper blacks and four-times improved rise time compared with DisplayHDR 1000; those are VESA’s stated comparisons, not a universal result for every OLED or LCD product. See VESA’s description at its True Black 600 announcement.
What the True Black tiers measure
The tier number corresponds principally to a minimum peak-luminance class, measured in candelas per square meter (cd/m²), also called nits. VESA’s current summary table lists these True Black thresholds and selected color requirements:
Rank #2
- 27" QHD DISPLAY: Immerse yourself in stunning visuals with a 27-inch QHD (2560x1440) resolution, delivering crisp detail and vibrant colors.
- 240Hz REFRESH RATE & 0.03ms RESPONSE TIME: Enjoy smooth, blur-free gameplay with a lightning-fast 240Hz refresh rate and ultra-low 0.03ms (GtG) response time.
- HDR400 TRUE BLACK: Experience deeper blacks and brighter highlights with HDR400 True Black certification, enhancing contrast and visual realism.
- QD OLED TECHNOLOGY: Quantum Dot OLED panel ensures rich colors with 147.6% sRGB and 110.2% DCI-P3 color gamut coverage, providing stunning color accuracy
- ADAPTIVE-SYNC TECHNOLOGY: Eliminate screen tearing and stuttering with Adaptive-Sync compatibility, ensuring a seamless and fluid gaming experience.
| VESA tier | Minimum peak luminance | DCI-P3 coverage | Maximum black level | Maximum ΔTP color-patch error |
|---|---|---|---|---|
| DisplayHDR True Black 400 | 400 cd/m² | 95% | 0.0005 cd/m² | 8 |
| DisplayHDR True Black 500 | 500 cd/m² | 95% | 0.0005 cd/m² | 8 |
| DisplayHDR True Black 600 | 600 cd/m² | 95% | 0.0005 cd/m² | 8 |
| DisplayHDR True Black 1000 | 1,000 cd/m² | 95% | 0.0005 cd/m² | 6 |
| DisplayHDR True Black 1400 | 1,400 cd/m² | 95% | 0.0005 cd/m² | 6 |
These are summary values from VESA’s current overview, not the complete test protocol. The standard also covers factors such as color accuracy, bit depth, HDR signal support, and pixel rise time. VESA’s detailed criteria and current tier information are linked from its DisplayHDR overview.

True Black versus ordinary DisplayHDR
The two families are related but target different display architectures. Ordinary DisplayHDR is primarily for backlit displays and includes static-contrast requirements. True Black targets OLED and other emissive displays, for which VESA lists static contrast as not applicable and instead sets a very low maximum black level.

Equal numbers across the families do not mean equal performance or interchangeable labels: DisplayHDR 500 and DisplayHDR True Black 500 use different criteria. The current family lineups and requirements are summarized at VESA’s overview.
What the tier number does—and does not—tell you
A higher True Black tier sets a higher minimum peak-luminance class, but it is not a complete picture-quality score. It is not a resolution, refresh rate, or color-depth label, and it does not promise that the rated peak will be sustained across the whole screen or in every picture mode.

OLED brightness can vary with the size and duration of bright areas, thermal conditions, firmware, and picture settings. Automatic brightness limiting (ABL) may reduce brightness on large bright images. These behaviors matter for desktop work as well as HDR gaming, but they are not captured by the tier number alone.

- For content creation, consider calibration, color management, uniformity, and whether the display meets the requirements of the specific workflow; certification alone does not establish reference-monitor performance.
- For long-term ownership, review the manufacturer’s burn-in warranty and usage policy rather than inferring them from certification.
How to verify a product’s certification
- Find the exact designation in the product listing or manufacturer specifications, such as “DisplayHDR True Black 500.” A generic “HDR” claim does not establish VESA certification.
- Search the exact model in VESA’s certified-products database. Check the model and tier rather than relying only on a family name or panel type.
- Confirm the display’s screen size, refresh rate, color mode, and connection requirements in the manufacturer’s specifications. Certification does not answer every compatibility question.
- Read independent testing for sustained brightness at different image sizes, tone mapping, color accuracy, uniformity, response, and gaming behavior.
VESA cautions that “HDR-400” without the formal “DisplayHDR 400” designation may be a pseudo-specification rather than a certified tier. OLED describes the panel technology; it does not by itself prove that a product holds any DisplayHDR True Black certification. VESA’s overview explains the formal labels and links to its verification resources: displayhdr.org.
How the standard has expanded since launch
- December 2017: VESA introduced the original DisplayHDR specification, aimed primarily at LCD-oriented HDR performance.
- January 3, 2019: VESA launched DisplayHDR True Black, initially with 400 and 500 tiers for OLED and other emissive displays. The announcement appears in VESA’s release archive.
- September 2, 2021: VESA added True Black 600, describing it as a 20% luminance increase over True Black 500. At launch, ASUS identified the Vivobook Pro 14, Vivobook Pro 14X, and Vivobook 15 as initial certified products. These are historical launch examples, not current buying recommendations. Details are in VESA’s 2021 announcement.
- Current VESA overview: The True Black family is listed at 400, 500, 600, 1000, and 1400. Consult VESA’s overview for the lineup as currently published.
What certification cannot tell you
Certification supplies a shared performance baseline, not a guarantee that two displays will look alike or that one will suit every buyer better. It does not fully describe tone mapping, factory calibration, uniformity, ABL behavior, input latency, viewing angles, text rendering, or long-term OLED wear. LCDs can offer higher full-screen brightness, and strong mini-LED models can create high-impact HDR; OLED generally retains an advantage in per-pixel black control. The right trade-off depends on how the display will be used.
