If you’re still having problems, you can also check the settings on your streaming device to make sure it’s able to display video in 4K resolution: This Sony soundbar indicates when Atmos playback has begun.
Likewise, some soundbars and receivers will indicate which audio format they’re using, so look for an “Atmos” indicator once playback begins.

This can tell you whether the TV has flipped over to 4K, HDR10, HDR10+, or Dolby Vision modes. On some TVs, you might be able to hit an info button on your television remote to see which picture mode it’s using. This Vizio TV clearly states when it’s outputting video in Dolby Vision HDR. That means you’ll need to check on individual programs to see if they support those higher-fidelity formats.Īside from using your eyes and ears, the best way to double-check whether you’re really getting the best video and audio quality is to see what your TV or soundbar says it’s putting out.
An even smaller number support HDR, Dolby Atmos, and advanced HDR formats such as Dolby Vision and HDR10+. Using the services above still doesn’t guarantee the best video and audio quality, as most streaming services only offer a subset of their movies and shows in 4K.

Plug your streaming device into that input, and your soundbar or receiver will pass the video along to the TV through the same cable that handles the audio. If your HDMI-ARC slot is also the one that provides the highest video quality, you’ll need a soundbar or receiver with its own 4K-capable HDMI input.

(This is especially true for devices with Dolby Vision HDR, which requires 12-bit color depth.) Check the labels on your HDMI ports or consult your TV’s manual for more details.įor Dolby Atmos, you’ll need a compatible soundbar or receiver hooked up to your TV’s HDMI-ARC slot, as the format doesn’t work over an optical cable or 3.5mm audio output (thoses connections just don’t have enough bandwidth to handle the data). You should also connect these devices to your TV’s best HDMI input, because some inputs may not support 4K or the color depth required for HDR. If you want to use an external streaming player with your 4K TV, make sure it supports 4K as well (as the Roku Express 4K+ does) to get the same picture quality. For instance, you’ll need a 4K-compatible streaming player, such as Roku’s Express 4K+ or Amazon’s Fire TV Stick 4K. The situation gets more complicated as you connect external streaming players to your TV, because now each link in the chain must support 4K and HDR as well.
