I got the 77C1 & was surprised with this very basic and easy to fix issues existence, subtitles is low res & pixilated and very apparent in bigger screens, I got some ideas that will improve the experience significantly:
1. At least 5 fonts to choose from.
2. More colors and formats go detailed as possible in adding this feature (opacity, background, window, shadows, outlines,..etc).
3. Find a way to make subs high res or vector as it should be in any media software ever existed I don't know how you managed to mess this up.
4. Font size slider that has more range than the current sizes.
these are some of my suggestions, if I repeated some of the quoted points coz it's important please try to find a solution before ditching the support for C1 to focus on C2 & after
''Seriously LG, please improve this in a firmware upgrade. This is not okay for the price of your televisions, it really ruins my film experience.''
