## In short

- Evaluating your screen requires legal, professionally mastered HDR test clips rather than compressed YouTube streams or pirated demo rips.
- Netflix Open Content provides studio-grade 4K 60fps HDR10 and Dolby Vision test films like Meridian and Sol Levante under Creative Commons licenses.
- Blender Studio open movies provide CC-licensed 4K high-frame-rate animation to test specular highlights, wide gamut colors, and banding.
- A proper display benchmark checks four key attributes: specular highlight roll-off, near-black shadow detail, color banding, and subtitle blooming.

To test whether your Mac or external monitor delivers genuine High Dynamic Range, you need professionally mastered, legal test videos with verified metadata rather than compressed web streams. Downloading official open-source test files from studios like Netflix and the Blender Foundation allows you to evaluate specular highlights, shadow detail, color banding, and subtitle blooming with scientific precision.

Many online demo websites distribute unlicensed movie rips or re-encoded files stripped of their mastering metadata. Testing your screen with compromised files leads to false conclusions about your display's capabilities. By using open-source, Creative Commons licensed master files, you can benchmark your hardware against exact industry standards.

## Where to find legal, studio-grade HDR test videos

Two creative institutions provide clean, studio-grade HDR test assets for free public download:

### 1. Netflix Open Content

Through its [Netflix Open Content initiative](https://opencontent.netflix.com/), Netflix distributes full production-grade media assets under Creative Commons licenses (CC BY-NC-ND 4.0) to help engineers, colorists, and enthusiasts benchmark display pipelines.

Two standout titles are essential for display testing:

- ***Meridian* (2016):** Directed by Curtis Clark, ASC, *Meridian* is a 4K 60fps narrative period short produced specifically to stress-test HDR mastering workflows. It is available in both 1,000-nit and 4,000-nit SMPTE ST 2084 (PQ) masters in the Rec. 2020 color space. The film features classic 1940s detective aesthetics: cigar smoke drifting through dim wood-paneled offices, chrome car bumpers reflecting bright sunlight, and car headlights piercing dark coastal fog at night.
- ***Sol Levante* (2020):** Directed by Akira Saitoh and co-produced by Production I.G and Netflix, *Sol Levante* is an experimental 4K 60fps anime short mastered in Dolby Vision with Dolby Atmos. It features hand-drawn animation combined with visual effects, showcasing vibrant neon particles, complex lighting effects, and deep blacks.

### 2. Blender Studio Open Movies

The Blender Foundation produces open-source animated films to advance the capabilities of its 3D creation suite, releasing every film and asset under Creative Commons Attribution licenses (CC BY 3.0 / CC BY 4.0) via [Blender Studio](https://studio.blender.org/):

- ***Charge* (2022):** A fast-paced cyberpunk action short rendered in real time using Blender EEVEE. It is filled with electrical arcs, sparks flying in shadowy industrial corridors, and glowing robotic power cores, making it an exceptional test for rapid local dimming response and peak highlight luminance.
- ***Spring* (2019):** An animated fable featuring rich mountain environments, deep forested shadows, and smooth pastel skies. It is ideal for evaluating wide color gamut transitions and spotting color banding.
- ***Tears of Steel* (2012):** A live-action science fiction short shot on the Sony F65 4K camera featuring extensive visual effects, suitable for testing fine textures and skin tone reproduction.

## What to look for when benchmarking your screen

When playing these test files on your Apple Silicon Mac or external monitor, focus your attention on four critical visual checkpoints:

### 1. Specular highlight brilliance and roll-off

Specular highlights are small, intensely bright reflections—such as the sun glinting off a car bumper, streetlamps at night, or electrical sparks.

In *Meridian*, watch the scene where the vintage automobile drives along the coastal road at night. When the high-beam headlights shine directly at the camera:
- On a high-performance HDR display (such as the MacBook Pro Liquid Retina XDR screen capable of 1,600 nits), the headlight center should glow with intense brightness while the surrounding fog and lamp housing retain distinct textures.
- If your display has poor tone mapping or low peak brightness, the lamp housing will blow out into a flat, solid white blob (highlight clipping), or the entire night scene will dim down excessively.

To understand how displays map high-nit files, see our guide on [what is HDR10](/maclc/blog/what-is-hdr10/).

### 2. Shadow detail and near-black gradation

Shadow detail (near-black retrieval) tests whether a screen can display subtle dark gradations without crushing them into pitch black or elevating them to washed-out grey.

In *Meridian*, examine the detective's dark wool overcoat inside the dimly lit police station:
- A well-calibrated display reveals the fine woven texture of the fabric and the subtle fold lines in the shadows.
- If your display or player crushes blacks, the coat will appear as an undifferentiated black silhouette.
- If your black levels are elevated due to an RGB range mismatch, the shadows will look murky and charcoal grey.

### 3. Color banding in smooth gradients

Color banding (posterization) occurs when an 8-bit pipeline or aggressive video compression creates visible stepped contour lines across smooth transitions.

In Blender's *Spring*, pause on the wide panoramic shots of the morning sky and misty valleys:
- In true 10-bit HDR, the sunrise gradient from deep blue to soft amber should blend smoothly across the entire panel.
- If you see distinct, stepped concentric rings resembling a topographical map, either the video is being truncated to 8 bits during decoding or your display panel lacks 10-bit color reproduction.

For the science behind this artifact, read our guide to [color banding in video](/maclc/blog/color-banding/).

### 4. Subtitle blooming and local dimming halos

Subtitle performance is one of the most revealing tests for displays that use local dimming backlights (such as mini-LED displays and full-array LCD monitors).

Load an SRT subtitle track over a dark scene in *Sol Levante* or *Charge*:
- If your media player draws subtitles at the HDR peak layer (1,000+ nits), the local dimming zones behind the text will flare brightly, creating a distracting milky halo that spills across the surrounding black screen and into the letterbox bars.
- Intelligent players keep subtitles at SDR white over HDR, preventing backlight flare and keeping text readable without eye strain.

Learn why this occurs and how to fix it in our explainer on [HDR subtitles too bright](/maclc/blog/hdr-subtitles-too-bright/).

## How to play HDR test videos on an Apple Silicon Mac

Playing professional test files on macOS requires software that respects high-bitrate containers and advanced color pipelines.

QuickTime Player is poorly suited for technical benchmarking because it refuses to open `.mkv` files and does not support dynamic HDR10+ metadata. Furthermore, QuickTime's basic Movie Inspector provides minimal technical feedback on how the display compositor is handling the stream.

MacLC serves as a test bench for Apple Silicon Macs. When a video opens, its format card shows whether the file carries HDR10, HDR10+, Dolby Vision (profiles 5, 7 base and RPU, 8.1, or 8.4), or HLG, and which format it selected for your display. It measures the screen's headroom and keeps subtitles at SDR white over HDR.

MacLC also makes it easy to verify that your screen is actually engaging its extended dynamic range. Open **Settings › HDR & Colour** during playback to view "What's happening right now," including your panel's live measured headroom and active color space. To confirm whether a test file has genuine HDR tags before playing, follow our checklist on [how to tell if a video is really HDR on Mac](/maclc/blog/how-to-tell-if-a-video-is-hdr/).

## Quick test checklist for your display

When running your test videos, keep this concise summary handy:

| Test Area | Recommended Test File | What You Want to See | What Indicates a Problem |
| :--- | :--- | :--- | :--- |
| **Specular Highlights** | *Meridian* (4,000-nit master) | Intense light in car headlamps; cloud textures visible. | Blown-out flat white blobs; overly dark scene. |
| **Shadow Detail** | *Meridian* (Detective office) | Clear fabric folds and wood grain in low light. | Crushed solid black silhouettes or milky charcoal grey. |
| **Color Banding** | *Spring* (Sunrise sky) | Smooth gradations with no visible steps. | Stepped, striped contour rings in skies. |
| **Subtitles** | *Sol Levante* (Dark credits) | Crisp, comfortable text with zero backlight blooming into letterbox bars. | Excessive glare and murky grey halos around letters. |

Using legal, studio-mastered test assets takes the guesswork out of display calibration. By putting your Mac through these cinematic benchmarks, you ensure that every movie you watch is rendered with accurate contrast, clean color fidelity, and authentic dynamic range.

## Questions people ask

### Where can I download legal HDR test videos for free?

The two best legal repositories are Netflix Open Content (opencontent.netflix.com), which offers studio production masters under CC licenses, and Blender Studio (studio.blender.org), which releases full 4K animated films under Creative Commons Attribution.

### Why shouldn't I use YouTube to test HDR on my Mac?

YouTube compresses videos aggressively with lossy VP9 or AV1 encoding and strips original mastering metadata. Standalone local test files let you inspect uncompressed 10-bit streams with their exact SMPTE ST 2086 metadata intact.

### What is Netflix Meridian used for?

Meridian is a 4K 60fps HDR test film produced by Netflix to benchmark mastering workflows. It includes dual masters (1,000 nits and 4,000 nits) specifically designed to test shadow contrast, smoke gradients, and specular highlights.

### How can I tell which HDR format a test file is using on Mac?

Open the file in MacLC or MediaInfo. MacLC's format card names the formats the file carries (HDR10, HDR10+, Dolby Vision or HLG) and the one it chose for your screen.
