How to Change Amazon Prime Video Quality Settings [2026 Stepwise Guide]

Part 1. Why Is My Amazon Prime Video Quality So Bad?

Prime Video does not always deliver the same resolution on every device. Even when you select the highest available setting, the service can reduce quality when bandwidth or device compatibility becomes a limitation.

Amazon also states that streaming quality can change according to bandwidth and compatible device capabilities. If the service detects that playback may be interrupted, it can reduce the resolution to keep the video playing.

Amazon Prime Video Quality Options Explained & Data Usage

Prime Video uses quality labels instead of always showing a fixed resolution. The exact resolution can vary based on the title, device, connection, and available playback format.

These figures are approximate and can vary by title, device, and platform. They should not be treated as guaranteed resolution or bitrate specifications.

The Best option uses significantly more data than the other settings. It is therefore more suitable for unlimited Wi-Fi or a high-data home connection.

It is also important to understand that “Best” does not automatically mean 4K on every device. A compatible 4K TV or streaming device may support Ultra HD, while a Windows PC or web browser may be limited to HD.

Why Is My Amazon Prime Quality Bad Even On “Best”?

Selecting “Best” only allows Prime Video to use the highest quality available under the current conditions. It does not force 4K playback when the device, title, or connection cannot support it.

Common reasons include:

• Internet bandwidth is too low.
• Wi-Fi signal is unstable.
• The title is not available in 4K.
• Your device has a resolution limitation.
• The Prime Video app is outdated.
• HDMI equipment does not support UHD.
• HDCP requirements are not satisfied.
• Other devices consume network bandwidth.
• Your TV is not configured for 4K.
• Prime Video automatically lowers quality.
• Browser playback has HD limitations.
• The source title has limited resolution.

A slow connection is one of the most common causes. Amazon recommends at least 15 Mbps for 4K Ultra HD playback on compatible Fire TV setups. A faster connection can still experience problems if the Wi-Fi signal is unstable or other devices are using the network.

Your device also matters. Current Amazon device information lists Prime Video support up to Ultra HD on selected Samsung, LG, and Sony Smart TVs, while its computer support pages list web browsers and Windows 10/11 playback up to HD.

Therefore, changing Amazon Instant Video quality settings cannot overcome a hardware or platform limit.

Part 2. How To Change Amazon Prime Video Quality Settings On Any Device?

The location of Prime Video’s quality controls depends on the platform. Mobile apps provide dedicated streaming-quality options, Fire TV uses its data-monitoring controls, and desktop playback usually exposes quality through the player. Many Smart TVs instead adjust quality automatically.

1. Change Amazon Prime Video Quality Settings On Mobile

The Prime Video mobile app provides the clearest manual controls for streaming quality. Android and iOS layouts can differ slightly between app versions, but the quality controls are generally found under the streaming and download settings.

On supported Android devices, Prime Video can stream up to Ultra HD, while Amazon currently lists iPhone and iPad playback up to HD.

Here's how to change video quality on Amazon Prime:

• Open the Prime Video app and sign in to your Amazon account. Tap “My Stuff” or your profile area, depending on the current app layout.

• Tap the gear icon to open “Settings," then open “Stream & Download” and go to “Streaming Quality.”

  

• Select “Best,” “Better,” “Good,” or “Data Saver” when those options are available. If you regularly use Wi-Fi, enable “Use Highest Quality on Wi-Fi” when the option appears. This allows the app to prioritize higher quality while connected to Wi-Fi.

The mobile setting controls streaming separately from downloaded video quality. Changing “Download Quality” does not automatically change the Amazon streaming video quality.

2. Change Prime Video Quality Settings On Firestick

On a Fire TV Stick, video quality can be controlled through Fire TV's system settings rather than only inside the Prime Video app. This is especially useful if you want to reduce bandwidth usage or prevent Firestick from automatically streaming at the highest available resolution.

• From the Fire TV home screen, open “Settings” and select “Preferences.”

• Open "Data Monitoring," then turn “Data Monitoring” on if the quality control is not visible.

  

• Select “Set Video Quality” and choose “Good,” “Better,” or “Best.” Press the Home button to return to the Fire TV interface.

Tips:

Choose “Best” if you want the highest available quality and your connection can handle it. Choose “Better” or “Good” when buffering or data consumption becomes a problem. For actual 4K playback, Fire TV also needs a compatible Ultra HD display and suitable HDMI equipment. Amazon recommends a high-speed connection of at least 15 Mbps for 4K Ultra HD on compatible Fire TV setups.

3. Change Prime Video Quality On Web Browser

The web player gives you quality control directly inside playback. This makes it useful when you want to quickly change quality without opening account settings. Amazon currently lists supported browsers, including Chrome, Firefox, Edge, Safari, and Opera. Its computer support information lists browser streaming up to HD.

• Open Prime Video in a supported web browser and sign in to your Amazon account.

• Start the movie or TV episode you want to watch, then move your cursor over the video to display the playback controls.

• Click the gear icon in the player and open the “Video Quality” option if it is available. Select “Good,” “Better,” or “Best.”

  

Note:

If “Best” still does not produce 4K, that may be expected. Current Amazon computer requirements list browser playback up to HD. A browser therefore should not be treated as a guaranteed method for watching Prime Video in 4K.

4. Adjust Amazon Prime Video Quality On Other Smart TVs

Smart TVs are different from mobile devices because many Prime Video TV apps do not provide a manual quality selector. Samsung, LG, and Sony Smart TVs support Prime Video up to Ultra HD on compatible models.

However, the exact controls depend on the TV model and software version. Here’s how you can change Amazon Prime Video quality settings on Smart TV.

• Open the Prime Video app on your Samsung, LG, Sony, or other supported Smart TV.

• Make sure the app is updated through your TV’s app store, then start a title that is advertised as HD or Ultra HD.

• Open the playback controls and look for a settings or quality option. If no quality selector is available, allow Prime Video to adjust playback automatically.

• Open your TV’s picture or input settings and confirm that the display is configured for the appropriate resolution.

• If you use an external streaming device, check its HDMI connection and display settings.

If the TV app does not provide a manual quality setting, there is nothing wrong with your installation. Prime Video can automatically adapt streaming quality based on network conditions and device capabilities.

5. Adjust Prime Video Quality On Its Windows App

The Prime Video Windows app provides streaming and download controls, but there is an important limitation. Amazon currently lists Prime Video for Windows 10/11 as supporting streaming up to HD. This means selecting the highest available option does not guarantee 4K playback on a Windows computer.

• Open the Prime Video app on your Windows 10 or Windows 11 computer.

• Sign in and start playing the movie or episode, then move the cursor over the video to display playback controls.

• Click the gear icon if streaming quality control is available, then choose the highest available quality, such as “Best,” when you want maximum available quality.

• If you are changing offline video quality instead, open the app’s settings and look for the “Download Quality” option.

  

• Choose the download quality based on your storage space and desired offline quality.

Do not confuse streaming quality with download quality. Download quality affects files saved for offline viewing, while streaming quality affects online playback. For a Windows PC, display resolution, DRM compatibility, graphics hardware, connection quality, and the title itself can also affect playback.

⚡ Part 3. How To Enhance Low-Resolution Local Prime Videos Up To 8K?

Prime Video streaming settings only affect how the service delivers online content. They cannot improve an existing low-resolution local video file.

For this purpose, 4DDiG Video Enhancer is a practical option. Powered by AI, it analyzes individual frames, reduces noise, sharpens details, and increases video resolution. Its supported enhancement workflows can upscale low-resolution videos to HD, 4K, and even 8K.

Key features include:

• Increase low-resolution video to HD, 4K, or up to 8K in supported enhancement modes.
• Reduce compression noise and improve blurry or unclear details.
• Multiple AI models for general footage, faces, and animated content.
• Improve color, contrast, and overall visual appearance.
• Restore old videos and colorize black-and-white footage
• Batch enhance multiple local videos instead of processing them individually.
• Check the enhanced result before exporting the final video.

Steps To Enhance Low-Resolution Videos With 4DDiG

• Install and launch 4DDiG File Repair on your computer. Open the “AI Enhancer” feature and click “Video Enhancer”.

  

• Import your local Prime video file by clicking “Add Videos”.

  

• Select the appropriate enhancement model and resolution, then click "Enhance".

  

• Preview the result and compare it with the original. Pay attention to faces, hair, edges, text, and moving objects. Save the enhanced video in your preferred format and save it separately from the original.

  

This approach is different from changing Amazon Prime Video app video quality settings. Prime Video settings control streaming delivery, while 4DDiG processes a local video file after it has already been saved on your computer.

FAQs About Amazon Prime Video Quality Settings

Q1: Is Amazon Prime Not 4K Anymore?

Yes, Prime Video still supports 4K Ultra HD on compatible titles and devices. However, availability depends on the title, device, TV, connection, and playback setup. If you only see HD, check whether the content supports 4K and whether your device and display meet the requirements.

Q2: How Do I Know If Amazon Prime Is Playing In 4K?

Check for a UHD/4K indicator during playback or in the title information. On Fire TV, you can also use Audio/Video Diagnostics to check the detected maximum resolution. Note that choosing Best quality does not necessarily mean the stream is actually playing in 4K.

Q3: Why Does Amazon Prime Video Look Bad Even On Best?

The Best setting only delivers the highest quality currently available. Slow internet, unsupported devices, low-resolution content, or platform limits can still reduce picture quality. Browsers and the Windows app may also have lower playback limits, so a compatible Smart TV or streaming device is preferable for 4K.

Q4: Does Changing Prime Video Quality Affect Every Device?

No. Quality controls can be device- or platform-specific. A setting on your phone does not guarantee the same playback behavior on a Smart TV, Fire TV, or computer. Set the appropriate quality preference on each device you regularly use.

Q5: How Much Data Does Amazon Prime Video Use At Best Quality?

Prime Video’s “Best” setting can use around 6.84 GB per hour according to the quality information shown by Prime Video. Actual usage can vary with the title, device, and stream. If you have a limited data plan, “Better” or “Good” can significantly reduce consumption.

Conclusion

The correct Amazon Prime Video quality settings depend on your device, title, internet connection, and display. Mobile and Fire TV users can adjust quality more directly, while Smart TVs often rely on automatic selection. Browsers and Windows currently have HD limitations.

For local low-resolution videos, 4DDiG Video Enhancer offers a separate AI upscaling workflow with support for higher-resolution output, making it useful when changing streaming settings is not enough.
