Check if Your TV Supports Apple TV 4K’s Best Features

This guide helps you determine whether your television can take full advantage of the Apple TV 4K’s headline features, such as Dolby Vision, HDR10+, Dolby Atmos, and 4K at 120Hz. You’ll learn what to look for in your TV’s specs and settings, and how to confirm compatibility before you invest in the streaming device or upgrade your TV.

What You’ll Need

• Your TV’s model number (usually found on the back panel or in the settings menu under System/About)
• Access to your TV’s settings menu
• A device to search the internet (phone, tablet, or computer) for your TV’s specs
• Optionally, an Apple TV 4K to test features directly (if you already own one)

Step-by-Step

1. Find your TV’s model number. Look on the back of the TV for a sticker or engraved text. It usually starts with letters and numbers (e.g., Sony XR-55A80J, LG OLED55C1PUB, Samsung QN65QN90AA). Alternatively, go to your TV’s Settings menu, then select ‘System’, ‘About’, or ‘Support’ to find the model code.
2. Search the model number online. Type your model number into a search engine and add the word ‘specifications’ or ‘specs’. Open the official manufacturer’s product page or a reputable tech review site.
3. Check for Dolby Vision and HDR10 support. Look for ‘Dolby Vision’ and ‘HDR10’ in the HDR section of the specs. Apple TV 4K uses Dolby Vision for its enhanced HDR experience, and HDR10 is the baseline for most 4K content. If your TV lacks both, you’ll still get 4K SDR (Standard Dynamic Range) but not the full visual impact.
4. Check for HDR10+ (if you care about Samsung or Amazon content). HDR10+ is a dynamic HDR format used by Samsung and some streaming services. Apple TV 4K does not support HDR10+ (it uses Dolby Vision instead), but if your TV only has HDR10+ and not Dolby Vision, you’ll get HDR10 (static) from Apple TV, which is still good but not the best.
5. Check for Dolby Atmos support. Look for ‘Dolby Atmos’ in the audio specs. Apple TV 4K outputs Dolby Atmos via HDMI (for soundbars/receivers) or through the TV’s speakers if they support it. If your TV lacks Atmos, you’ll get standard 5.1 or stereo audio.
6. Check for 4K 120Hz support (for high refresh rate gaming). If you plan to play games on Apple TV 4K, look for ‘120Hz’ or ‘4K 120’ in the specs. This is only available on the Apple TV 4K (3rd generation) and requires a TV with HDMI 2.1. Most TVs from 2020 onward have this, but older 4K TVs are limited to 60Hz.
7. Verify HDMI ports and eARC. Check that your TV has an HDMI port that supports HDMI 2.0 or 2.1. For Dolby Atmos passthrough to a soundbar, you need an HDMI ARC or eARC port. If you’re using a soundbar, ensure it also supports Atmos.
8. Check your TV’s settings for ‘Enhanced HDMI’ or ‘HDMI UHD Color’. Many TVs require you to enable full-bandwidth HDMI on the port you’ll use. Go to Settings > Channels & Inputs (or similar) and turn on ‘HDMI UHD Color’ (LG), ‘Enhanced HDMI’ (Sony), or ‘Input Signal Plus’ (Samsung). Without this, 4K HDR may not pass through.
9. If you have an Apple TV 4K, plug it in and test. Connect the Apple TV to the HDMI port you’ve enabled. Go to Apple TV Settings > Video and Audio > Video Output. If your TV supports Dolby Vision, you’ll see ‘Dolby Vision’ as an option. Also check ‘Audio Output’ for ‘Dolby Atmos’ availability.
10. Check for network requirements. For the best streaming quality, your TV should have a stable internet connection (either via Wi-Fi or Ethernet). Apple TV 4K also supports Wi-Fi 6, but if your TV is older, that’s not a factor for the TV itself.

Common Mistakes

• Assuming all 4K TVs support HDR. Many budget 4K TVs only support SDR. Check the specs carefully.
• Confusing HDR10 with HDR10+. HDR10 is static, HDR10+ is dynamic. Apple TV uses Dolby Vision (dynamic), so HDR10+ is not a substitute.
• Ignoring HDMI port limitations. Some TVs only have one or two HDMI 2.1 ports. Make sure you’re using the correct one.
• Not enabling the HDMI enhanced mode. This is the most common reason why 4K HDR appears washed out or doesn’t work. Always check your TV’s input settings.
• Thinking 4K 120Hz is essential. For movies and TV shows, 60Hz is fine. 120Hz is only for gaming and some sports content.
• Assuming Dolby Atmos works through HDMI ARC. For full Atmos, you need eARC or an HDMI connection directly to a soundbar/receiver. ARC (without the ‘e’) often only passes compressed Atmos, which may not work with all soundbars.

Tips

• Use the official manufacturer’s website for specs. They are the most reliable source.
• Check the year of your TV. Generally, TVs from 2017 or later support HDR10, and 2018+ for Dolby Vision (on select models).
• If you’re buying a new TV, look for ‘Dolby Vision’ and ‘Dolby Atmos’ badges. These are the most important for Apple TV 4K.
• For gaming, prioritize HDMI 2.1 and 120Hz. But also ensure your HDMI cable is certified for 48Gbps (Ultra High Speed).
• Test with a known 4K HDR video. On Apple TV, play a movie like ‘The Morning Show’ or a nature documentary to see if HDR is working (the picture should be bright and vibrant).

Troubleshooting

If you’ve checked the specs and still don’t see the options on your Apple TV:

• Check your HDMI cable. Use a cable that is certified for high-speed (18Gbps) or ultra-high-speed (48Gbps). Older cables can cause issues.
• Try a different HDMI port. Some ports may not support full bandwidth. Refer to your TV’s manual.
• Update your TV’s firmware. Sometimes HDR support is added or improved via updates. Go to Settings > Support > Software Update.
• Reset the Apple TV’s video settings. Go to Settings > Video and Audio > Video Output and select ‘Reset Video Settings’. This can resolve handshake issues.
• If HDR still doesn’t work, your TV may not actually support it. Double-check the specs with the model number on the manufacturer’s site. Some TVs claim ‘HDR’ but only support HDR10, not Dolby Vision.
• For Dolby Atmos, ensure your soundbar/receiver is connected properly. Use eARC if available, and set the audio output to ‘Auto’ or ‘Dolby Atmos’ on the Apple TV.

Frequently Asked Questions

Can I use Apple TV 4K on a 1080p TV?

Yes, it works, but you’ll get 1080p SDR. You won’t get 4K, HDR, or 120Hz features.

Does my TV need to support Dolby Vision for Apple TV 4K to work?

No, it will still work with HDR10 or even SDR, but you won’t get the best picture quality.

Is HDR10+ a problem for Apple TV 4K?

No, Apple TV 4K doesn’t support HDR10+; it uses Dolby Vision. If your TV only has HDR10+, you’ll get HDR10 from Apple TV, which is still good.

What is the minimum HDMI version needed for 4K HDR?

HDMI 2.0 is required for 4K HDR at 60Hz. For 4K 120Hz, you need HDMI 2.1.

Can I get Dolby Atmos from the TV’s built-in speakers?

Some newer TVs with upward-firing speakers support Atmos, but most don’t. You’ll need a soundbar or receiver for full Atmos effect.

How do I know if my TV is 120Hz?

Check the specs for ‘120Hz refresh rate’ or ‘4K 120’. Also, look for ‘HDMI 2.1’ ports. You can also test by playing a 120Hz video on Apple TV and seeing if the output matches.
