This is about the DX-22L150A11 model but I suspect other Dynex models have the same feature.
The menu offers the following aspect ratios: auto, normal, wide, zoom, cinema.
All of them are self-explanatory except for "cinema". This ratio both magnifies the image and stretches it causing massive overscan on all four sides.
I'm new to all this, so please forgive me if I'm asking a daft question, but what possible value is this "cinema" aspect ratio?
