Apple TV 4K
Audio & Video Setup

Every setting you need for perfect playback. Walk through once, never think about it again.

01

Video

Open the Settings app on your Apple TV and go to Video and Audio. Here are the settings to change and why.

Format
Set to4K SDR, 60Hz
Find itSettingsVideo and AudioFormat

This keeps your Apple TV home screen in SDR so it doesn't force your TV into HDR mode all the time. When you play HDR or Dolby Vision content, the ATV4K will switch automatically. You'll see a brief black screen, which means it's working correctly. If you have an older 1080p TV, choose 1080p instead. The 60Hz part keeps menus and navigation feeling smooth.

HDMI Output
Set toDepends on your model

RGB High. The 1st and 2nd gen models have a known bug that adds a green tint when using YCbCr. Setting it to RGB High avoids this problem completely.
Chroma
Set to4:4:4
Find itSettingsVideo and AudioChroma

This only shows up if you chose YCbCr above (3rd Gen). It controls how much color information gets sent to your TV. 4:4:4 means full color detail with no compression and the most accurate picture.

Match Dynamic Range
TurnOn
Find itSettingsVideo and AudioMatch ContentMatch Dynamic Range

When enabled, your ATV4K automatically switches between SDR, HDR, and Dolby Vision depending on what you're watching. Without this, your TV might display SDR content in HDR mode (which looks washed out) or the other way around.

Match Frame Rate
TurnOn
Find itSettingsVideo and AudioMatch ContentMatch Frame Rate

This makes the ATV4K output the actual frame rate of your content (24fps for movies, 50/60fps for sports, etc.). Without it, movies can look stuttery or "juddery" because the TV is trying to convert frame rates on its own.

Not working well for you?
There is no one-size-fits-all solution here. Too many variables (different TVs, different apps) for a single setting to work equally well for everyone. While it's generally recommended to let the ATV4K output the correct frame rate natively to avoid A/V issues (one of its major strengths), in some cases this may not be ideal. If your TV doesn't handle the signal correctly, or the streaming app you're using doesn't support frame matching, try turning Match Frame Rate off and letting your TV handle the pulldown instead.
02

Audio

Still in Settings › Video and Audio. One important thing to know: the Apple TV 4K doesn't pass audio straight through. It converts everything to uncompressed LPCM internally. Keep that in mind for the settings below.

Audio Format
Set toAuto
Find itSettingsVideo and AudioAudio Format

Make sure "Change Format" is turned off. This keeps your audio as uncompressed LPCM, which is the highest quality the ATV4K can output. If you have an Atmos-capable soundbar or receiver, also set "Atmos Available" to on. If you don't have Atmos gear, go to Immersive Audio and turn it off.

Continuous Audio Connection
DefaultLeave Off
Find itSettingsVideo and AudioAudio FormatHDMI Output

New in tvOS 26.4. When enabled, the Apple TV holds a constant Dolby MAT connection to your receiver or soundbar. All non-Atmos audio is packaged as 7.1.4 LPCM at 16 bit / 48 kHz with silent objects wrapped inside a Dolby MAT container, so the downstream system always sees what looks like an Atmos stream. This comes with both upsides and downsides and isn't a set-and-forget toggle — the observations below are from testing with a 7.2.4 AVR setup, a 3.0 AVR setup, and a 3.1.2 soundbar.

What it fixes
  • Audio dropouts and delays when switching between Stereo, 5.1, and Atmos are gone — transitions between formats are seamless.
  • Eliminates volume differences between Stereo, DD+, and Atmos content. This is precisely where some systems have issues with volume fluctuations due to LPCM.
  • No interruptions when playing Apple Music or when switching formats, e.g. if one track is in Atmos and the next isn't.
  • Can resolve lip-sync issues if you're using eARC.
  • Can resolve audio "pops" or crackling sounds on some systems.
What it breaks
  • Most AVRs and soundbars will assume the ATV's audio output is always true Atmos, which can result in incorrect channel behaviour or altered surround processing.
  • Upmixing to surround sound (Dolby Surround, DTS Neural:X and others) may no longer be possible. There is no upmixing from an Atmos source, and upmixing from 7.1.4 channels may be faulty because your system assumes there is nothing to upmix.
  • The ATV always transmits Atmos in a compressed form, down to 16 bit instead of 24 bit. This also applies if CAC is disabled — it's an ATV limitation either way. But with CAC enabled, lossless audio (from Infuse, for example) is affected too, which can lead to a reduced dynamic range.
Bottom line
This isn't a feature you can set up once and just forget about, since it depends on the specific system and whether you can resolve any issues with it. Unless you need CAC for one of the reasons above, it's probably best to leave it disabled, as it comes with certain drawbacks. In the end it comes down to the individual system, settings, and preferences.
Audio Mode
Set toAuto
Find itSettingsVideo and AudioAudio Mode

Lets the Apple TV handle audio routing on its own. No need to touch this.

Reduce Loud Sounds
TurnOff
Find itSettingsVideo and AudioReduce Loud Sounds

This is a personal preference, but turning it off preserves the original dynamic range of your movies and shows. Quiet parts stay quiet, loud parts hit properly.

Volume feels too low?
This is a common complaint. The ATV4K converts all audio to LPCM, and some receivers/soundbars handle the volume level (Dialnorm) differently. The fix: go into your receiver or soundbar's settings and increase the volume specifically for the HDMI input your ATV4K is connected to.
Have an older system that doesn't support LPCM?
As a last resort, go to Settings › Video and Audio › Audio Format › Change Format and switch to Dolby Digital. This outputs compressed audio so older systems can play it, but you'll lose quality. Only do this if nothing else works.
03

Your HDMI chain

Now leave the Apple TV settings and open your TV's own settings menu. Every device between the ATV4K and your display needs to be configured correctly, or HDR, Dolby Vision, and audio can silently break.

HDMI Black Level
Set toLimited
Find itYour TVPicture SettingsHDMI Black Level

Many TVs have this set to "Auto" by default, but Auto frequently gets it wrong. You'll end up with crushed blacks (dark scenes become a black blob) or a washed-out, grayish picture. The "Full" option is only meant for when you're using your TV as a PC monitor. All streaming content and Blu-rays use the limited color range, so set your TV to match.

HDMI Signal Format
Set toEnhanced
Find itYour TVExternal Input SettingsHDMI Signal Format

Your TV might call this "Enhanced Plus", "HDMI Deep Color", "Input Signal Plus", or something else entirely. This tells your TV to accept the full HDR and Dolby Vision signal from the ATV4K. Without it, you can lose black detail, get washed-out images, or HDR might not work at all. Important: if you have a soundbar or AV receiver in between, check if those devices have their own HDMI signal settings and set them to Enhanced too.

TV Pulldown / Telecine
TurnOff
Find itYour TVPicture SettingsMotion / Film Mode

Since you turned on "Match Frame Rate" on the ATV4K, the Apple TV is already sending the correct frame rate to your TV. If your TV also tries to do its own frame rate conversion, the two will conflict and you'll get stuttering or dropped frames. Turn off your TV's version. Every brand calls it something different: Sony calls it CineMotion, LG calls it Real Cinema. Check your TV's motion or picture settings.

04

Dolby Vision profiles

You don't need to change any settings here. This is just helpful background. The ATV4K supports several HDR formats, but Dolby Vision comes in different "profiles" that behave very differently.

P5

Profile 5 — Streaming

Used by every major service. No HDR10 fallback, so unsupported devices show green/pink. ATV4K plays P5 with excellent color accuracy.

Best on ATV4K
P8

Profile 8 — Hybrid

Supports both HDR10 and DV. Converted from P7/P5 for compatibility. Most third-party players handle it. Worse color accuracy than P5 on ATV4K, but few will notice.

Most compatible
P7

Profile 7 — UHD Blu-ray

Dual-layer format for physical media. Requires dedicated UHD player hardware. Not on ATV4K, won't ever be. Fusion can't work around this.

Not supported
05

Fusion-specific settings

Everything above applies to any app on your ATV4K. This section is specifically for the Fusion player and its limitations.

Cache to Disk
TurnOn

This tells the Fusion player to buffer the stream ahead of time. Instead of loading each chunk right when you need it, the ATV4K downloads content in advance, which prevents stuttering and buffering interruptions during playback.

Licensing. Premium codecs need a third-party player to decode first. Apple doesn't hold the licenses.
