Hello,
I need to enlarge the font size for the visually impaired, the Hisense TV has the Vidaa software installed, can Android TV be installed, alternatively can I root and customize this feature?
I did not note any text or images to indicate such.
No harm in contacting Hisense for confirmation or guidance about how to do so if there are any end-user configurable options available regarding font size.
However, if you can likely control the font size via the video source then the larger font may be more visible to the impaired user.
Or, perhaps, just apply magnification as necessary if magnification is possible.
Windows provides support via "WIN" + "I" > Ease of Access > Display > Magnification
