Summary and next steps
Try a readable caption style with the viewer, then keep a way to restore the original settings. Device and app controls may differ.
- Record the TV, app and starting caption style.
- Compare text size, contrast and background on a familiar programme.
- Check whether the chosen style carries over to other apps.

If captions disappear against a bright scene, compare their size, color and background before buying equipment. There is no single preset that works for every person with macular degeneration. Let the viewer choose what is comfortable from their usual seat.
1. Record the starting setup
Write down the TV or streaming-box model, the app and the current caption setting. Ask before changing someone else’s familiar setup. Photograph the original settings screen if the owner agrees, avoiding account or payment details. Keep a way to restore the original style.
Use the normal seat and a familiar program. Pause while navigating menus. You do not need to move furniture, endure discomfort or buy a larger television to try a reversible caption change.
2. Find the right caption controls
Captions may be controlled by the TV, a connected streaming box, the app, or a combination. Options also depend on the program and software version. Captions cannot be enabled if the provider has not supplied a track.
Roku
From Home, open Settings, then Accessibility and Captions mode. Some models list Captions directly. For appearance, look for Accessibility, then Caption style. Roku documents options for text, background and window; apps using their own caption controls may ignore the device setting. Roku’s current caption instructions explain model and app differences.
Apple TV 4K
In Settings, look under Accessibility for Subtitles and Captioning. Use Style to choose or edit a caption style; labels can vary with tvOS. Apple’s closed captions and SDH guide lets you select your software version. The Apple TV app on another television may have different menus.
Other televisions and apps
Use the manufacturer’s help for the exact model. Search its support site for captions, subtitles or accessibility. In a streaming app, check the playback speech-bubble or subtitle menu and any profile caption settings. Do not assume a menu path for one brand applies to another.
3. Compare a readable style, one change at a time
- Text size: Increase or decrease until the viewer can follow a real sentence from their usual seat. Check that text is not cut off or crowded.
- Background: Compare a dark caption background with the original style. Keep the wording distinguishable when the picture changes.
- Text color and edge: If supported, compare a plain font, contrasting color and outline. Ask the viewer which makes words easier to recognize rather than choosing for them.
- Actual playback: Try the same short section with a bright scene and a darker scene. This is a practical comparison, not a validated vision test or a timed reading requirement.
- Reversal: If a change makes reading harder, restore the previous setting. Stop if viewing becomes uncomfortable.
Do not assign a medical score or choose a “safe” viewing distance from this exercise. A browser preview cannot reproduce your television, seating distance, glare or vision. The caption sample below is only a way to compare on-screen preferences.
4. When settings do not carry over
- One app looks different: Check that app’s caption controls and the profile currently in use.
- Only one program is affected: Check available languages and caption tracks. Ask the provider about missing or incorrect captions.
- A connected box is being used: Check its controls as well as the television’s.
- Words are part of the picture: Burned-in text cannot usually be restyled using closed-caption settings.
- An update changed the appearance: Use your saved record and the current official help page to restore the preference.
If captions remain difficult, ask the provider about available alternatives such as audio description. If daily viewing or reading has become harder, discuss vision changes and rehabilitation options with the eye-care team. Device changes do not treat AMD.
5. Keep a simple settings record
- Device and software version, if known
- App and profile used
- Caption language and mode
- Text size, color, background and outline preference
- How to restore the previous setup
- What remains difficult and whom to ask for help
No personal health details are needed in this record. Keep it where the viewer can use it independently.
