IMAX Enhanced Meaning & How to Use It

IMAX Enhanced is a certification and home theater program that brings IMAX-style picture, sound, and aspect ratio to select 4K TVs, projectors, soundbars, and streaming content. You enter your device type and content source to understand what IMAX Enhanced delivers, and the program tells you which features—like expanded aspect ratio and DTS audio—you can expect. This article explains what the label means, how it works, and how to actually use it with your gear.

Formula

The calculator estimates the vertical picture expansion you get when an IMAX Enhanced title switches from a standard widescreen (2.39:1) to IMAX’s expanded aspect ratio (1.90:1). The formula is:

Expansion (%) = ( (2.39 / 1.90) – 1 ) × 100

• 2.39 – standard widescreen aspect ratio (width ÷ height)
• 1.90 – IMAX digital aspect ratio (width ÷ height)
• Expansion – how much taller the image becomes on your screen

For a 65-inch TV, the physical height increases from about 25.4 inches to 32 inches when the full 1.90 frame is used.

Worked Example

Using the defaults: content type = Movie, display size = 65 inches.

1. Compute the ratio of the two aspect ratios: 2.39 ÷ 1.90 = 1.2579
2. Subtract 1: 1.2579 − 1 = 0.2579
3. Multiply by 100: 0.2579 × 100 = 25.79%

The calculator rounds to 26% – that’s how much taller the picture becomes when an IMAX Enhanced movie switches to its expanded scenes. The DTS audio note simply indicates that the format includes DTS:X soundtracks on compatible discs.

What IMAX Enhanced Actually Is

IMAX Enhanced is a licensing and certification program co-developed by IMAX and DTS (now part of Xperi). It’s not a new video codec or a separate streaming service. Instead, it’s a set of specifications that content creators and hardware makers follow to deliver a more IMAX-like experience at home.

The program has two main parts:

• Certified displays and sound systems – TVs, projectors, soundbars, and AV receivers that meet IMAX’s performance criteria for brightness, contrast, color, and audio.
• IMAX Enhanced content – movies and documentaries mastered with IMAX’s proprietary post-production process, often including a taller 1.90:1 aspect ratio for select scenes.

It’s important to note that IMAX Enhanced is not the same as watching a film in an IMAX theater. The home version uses the same brand name but is optimized for living-room viewing.

How It Works: Picture and Sound

The core of IMAX Enhanced is the expanded aspect ratio. Many blockbuster films are shot with IMAX cameras, capturing a taller frame than the typical widescreen. In theaters, those scenes fill the entire IMAX screen. At home, the IMAX Enhanced version preserves that taller image instead of cropping it to fit a standard 16:9 or 2.39:1 frame.

For sound, IMAX Enhanced relies on DTS:X, an object-based audio format similar to Dolby Atmos. The certification requires that soundbars and receivers deliver a specific level of clarity, bass, and surround immersion. When you play an IMAX Enhanced Blu-ray on a certified system, the audio is automatically decoded in DTS:X, placing sounds around you in 3D space.

On streaming platforms like Disney+ or Sony Pictures Core, IMAX Enhanced titles are delivered with the expanded picture and a special IMAX signature sound mix. The streaming version may use a different audio codec (like Dolby Digital Plus) but still carries the IMAX Enhanced branding.

How to Use IMAX Enhanced

Using IMAX Enhanced requires three things: a certified display, a certified audio device (or a TV with built-in speakers that meet the spec), and IMAX Enhanced content. Here’s how to set it up:

1. Check your hardware – Look for the official IMAX Enhanced logo on your TV, projector, soundbar, or AV receiver. It’s usually printed on the box or in the user manual. Many Sony, TCL, Hisense, and Philips TVs carry the certification.
2. Connect compatible devices – If you have a separate soundbar or receiver, make sure it also has the IMAX Enhanced badge. Use an HDMI eARC connection for the best audio quality.
3. Find IMAX Enhanced content – Look for the IMAX Enhanced badge on streaming apps like Disney+, Sony Pictures Core, or on Ultra HD Blu-ray discs. The badge is usually shown next to the title’s description.
4. Enable the mode – On some TVs, you may need to turn on IMAX Enhanced in the picture settings. This is often called “IMAX Mode” or “IMAX Enhanced.” It adjusts the picture to match the content’s intended look.
5. Press play – Once you start an IMAX Enhanced title, the TV should automatically switch to the expanded aspect ratio for compatible scenes. You’ll see the image fill more of your screen vertically.

If you don’t have a certified TV, you can still watch IMAX Enhanced content, but you won’t get the full benefit. The picture will be letterboxed (black bars) or cropped, and the sound will be standard rather than DTS:X.

Common Problems and Misconceptions

One frequent misunderstanding is that IMAX Enhanced is a resolution upgrade. It is not – it’s about aspect ratio and audio. You don’t need an 8K TV to enjoy it; a 4K TV is sufficient.

Another issue is that not all scenes in an IMAX Enhanced movie use the taller ratio. Only scenes shot with IMAX cameras expand. The rest of the film stays in standard widescreen. This means the image will shift between aspect ratios during playback, which some viewers find distracting.

Some users report that IMAX Enhanced mode on their TV makes the picture look too dark or too bright. This is usually because the mode is designed for a dark room. If you watch in a bright living room, you may need to adjust the brightness or turn off the mode.

Finally, IMAX Enhanced is not available on all streaming services. It’s limited to a few platforms, so you may need to buy or rent specific titles to get the full experience.

IMAX Enhanced vs. Dolby Vision and Atmos

IMAX Enhanced competes with Dolby Vision (for picture) and Dolby Atmos (for sound), but they’re not mutually exclusive. Some IMAX Enhanced titles also support Dolby Vision and Dolby Atmos on certain platforms.

• Picture – Dolby Vision uses dynamic metadata to adjust HDR scene by scene. IMAX Enhanced uses a fixed HDR10 or HDR10+ base with its own color grading. IMAX’s advantage is the taller aspect ratio; Dolby’s advantage is more precise tone mapping.
• Sound – DTS:X and Dolby Atmos are both object-based. The main difference is that DTS:X is often less compressed on Blu-ray, while Atmos is more common on streaming. IMAX Enhanced mandates DTS:X on disc, but streaming versions may use Atmos.

If your TV supports both, you can choose which to prioritize. For IMAX Enhanced content, the aspect ratio expansion is automatic, but you can often switch the HDR mode between IMAX Enhanced, Dolby Vision, or HDR10 in the TV’s settings.

Costs and Availability

IMAX Enhanced itself is free – it’s a certification, not a subscription. The cost comes from the hardware and content:

• Certified TVs – These are typically mid-range to high-end models, so you’ll pay a premium compared to non-certified equivalents.
• Certified soundbars/receivers – Similar premium applies, though some budget soundbars now carry the badge.
• Content – IMAX Enhanced movies are available on streaming services you may already subscribe to (like Disney+), or as Ultra HD Blu-rays that cost more than standard discs.

There are no ongoing fees or royalties for consumers. The certification is between IMAX and the hardware/content makers.

Frequently Asked Questions

Do I need an IMAX Enhanced TV to watch IMAX Enhanced content?
No. You can watch the content on any 4K TV, but you’ll miss the expanded aspect ratio and the optimized sound. The TV will show the standard widescreen version, and audio will be regular DTS or Dolby.

Is IMAX Enhanced the same as IMAX in theaters?
No. The home version uses the brand but is scaled for living rooms. The aspect ratio is similar, but the screen size, brightness, and sound system are far less powerful than a real IMAX theater.

How do I know if a movie is IMAX Enhanced on Netflix?
Netflix does not currently offer IMAX Enhanced titles. Check Disney+, Sony Pictures Core, or the Blu-ray case for the badge.

Can I turn off IMAX Enhanced mode on my TV?
Yes. In your TV’s picture settings, you can switch from IMAX Enhanced to another picture mode like Cinema or Filmmaker Mode. The aspect ratio expansion will stop, and the image will be cropped to standard widescreen.

Does IMAX Enhanced work with gaming?
No. IMAX Enhanced is for movies and documentaries only. It has no gaming-specific features, and enabling it on a game console input may cause input lag.

Why do some scenes have black bars and others don’t?
That’s normal. Only scenes filmed with IMAX cameras use the taller 1.90:1 ratio. The rest of the film uses the standard 2.39:1 widescreen, so black bars appear at the top and bottom during those scenes.
