Let's start with the basics of Hulu's video quality options. As it stands, you can watch Hulu in five different resolutions: standard definition, 720p, 1080p, 4K Ultra HD and 60fps high definition. Which of these you get depends on a range of factors, including the type of device you are streaming from, the content you're watching and the available bandwidth.  Every time you turn on Hulu, the video quality of your program is naturally capped by both what you are watching and the device you're using. 

Typically, Hulu will identify programming in which higher resolutions are available via badges on the content's "Details" tab, including 4K Ultra HD, HDR, and 5.1 Dolby surround sound. But a video quality badge doesn't guarantee that you'll be watching this content with the highest possible resolution. For instance, the streamer hosts an ever-widening library of 4K programming. However, not all devices and streaming avenues support 4K. Hulu's website, for example, can only stream in either standard definition or 720p. Moreover, whether you reach the higher of these two resolutions further depends on if your device is HDCP compliant.

Similar questions persist across content and device types. Typically, streaming shows, events and films via a Hulu app will render better results than your web browser. However, not all applications are created equal. Televisions and gaming consoles, for instance, can reach higher resolutions than those on your phone or tablet. Even within those lines, the quality of your stream can depend on brand compatibility.

For instance, if you use Hulu for live sports or other television broadcasts, you'll likely watch in either 720p or 1080p. The latter of these resolutions can only be reached via select products, however, including fourth-generation Apple TVs, Chromecasts, Samsung TVs, Fire TVs, Fire Sticks and certain gaming consoles. Other streaming devices, such as Rokus, Vizio SmartCast TVs, and Android televisions can only support 720p. To learn where your streaming device lands on these spectrums, visit Hulu's help center.

Your stream quality is further determined by the available bandwidth. Like internet service providers, streamers often manipulate resolutions to reduce internet traffic congestion. Although common, the practice has landed streamers in hot water with customers and courts alike. In 2020, for instance, a class action lawsuit claimed that Hulu throttled web browsing streams to push their proprietary applications. Such accusations shouldn't necessarily turn you from Hulu, however, as several competitors have also been roundly criticized for the practice. At this point, some simply chalk it up as a necessary evil of the streaming boom.

You can take several steps to improve your video quality. First, set yourself up for success by opting to watch Hulu through its application rather than your web browser. Migrating your viewing experience to your television can further upgrade your viewing experience. Choosing films and television programs that offer higher resolutions can also improve your streaming quality.

Unfortunately, these steps won't help if your internet connection is lacking. To maximize your experience, Hulu suggests viewers' networks boast a download speed of at least 3 Mbps. For bandwidth-intensive content, such as live events and 4K resolution, Hulu recommends at least 8 Mbps and 16 Mbps, respectively. Limiting other data-consuming activities, like music or video games, can further free up bandwidth for your Hulu stream.

Now let's dive into your settings. To give viewers greater flexibility in choosing their data preferences, Hulu enables users to choose one of two video quality options. The first, dubbed "Data Saver," allows you to reduce your data consumption by automatically downgrading the quality of your streams. The other option is "Best Available," which opts for the highest quality streaming resolution within your content, device and bandwidth constraints.

You are most likely to experience noticeable streaming setbacks using Hulu's phone applications. Because mobile users are more wary of high data usage, Hulu's iOS and Android phone applications are set to "Data Saver" by default. To change these settings, simply open the application on your mobile device and tap your account icon. Next, select "Settings" and navigate to the "Cellular Data Usage" tab. From there, you can choose which of the two data options you would prefer.

If you are streaming Hulu on you web browser, you can adjust your video settings by clicking on the gear icon during playback. Next, select your desired video preference under the "Quality" tab. Notably, such settings-tinkering is impossible on your television, presumably because your application automatically opts for the best available resolution.
