Interface text and subtitle text often have separate size controls. Enlarging system text may improve menus without changing captions, while an app can ignore unsupported scaling. Adjust both areas through documented settings and check that important controls remain visible. Decide whether the difficulty is reading menus or reading programme captions, then use the relevant supported control. Increasing interface scale may leave captions unchanged, and enlarging caption text cannot repair a clipped search label or an unreadable account dialog.
Test real screens
A larger setting can reveal clipped labels. Increase the supported interface text size and inspect the actual screens used most: category names, search results, settings and playback dialogs. Check that words remain complete and that buttons still fit without hiding their meaning. A layout that works at the default size may clip at a larger scale. Record the specific screen and setting if labels overlap, since the application's layout needs attention rather than another change to the programme's subtitle track.
Keep captions independent
Text tracks may have their own styling controls. Open a supported text caption track and adjust its own size, outline or background from the normal viewing position. Check two-line cues and bright scenes as well as a single line over darkness. Image-based or burned-in captions may not respond to the same controls, so determine track type if nothing changes. Keep picture zoom separate, because zoom enlarges the entire image and can crop captions or other information instead of improving text layout independently.
Avoid hidden tweaks
Unsupported scaling changes can make navigation harder. Use only the platform's ordinary scaling or accessibility options documented for the device. Unsupported density commands or hidden service settings can make controls unreachable and are poor first choices for a household viewing setup. Keep the original size recorded and verify that remote focus, dialogs and the back path remain usable after adjustment. If the app ignores the supported setting, report that behavior with the version and screen rather than assuming a larger television will necessarily solve the interface problem.

An example to work through
Menus become readable after text scaling, but captions still need their own size setting. Larger system text makes catalogue labels readable, but captions remain unchanged because the player has a separate text-track control. Adjusting each at its own supported setting gives readable menus and dialogue without zooming the entire picture or cutting off the edge graphics.
Questions about this topic
Does one slider affect everything?
Not necessarily. The interface and timed-text renderer can use separate settings and support paths.
Can burned-in subtitles scale independently?
No. They are part of the picture. Enlarging them requires enlarging the picture itself, which also changes framing.
